Full textAbstract:
This paper presents a preliminary analysis of light rail crashes at at-grade crossings in Denver, Colorado, based on Regional Transportation District data for 1999 through 2009. Differences in design and operation of at-grade crossings are discussed for light rail versus common carrier railroad (railroad). The differences appear to warrant the development of separate crash prediction and hazard index models because models developed for railroad at-grade crossing operations may not accurately predict the number and severity of crashes at light rail at-grade crossings. In addition, the models developed for railroads do not predict crashes at crossings for some traffic control device types such as traffic signals. The lack of information for crossings controlled by traffic signals in the railroad crash prediction equations is one reason why equations specific to light rail may need to be developed. This study identifies patterns in light rail crossing crash data that warrant further investigation and support the development of crash prediction models and hazard index equations specific to light rail at-grade crossing configurations and operations.

Introduction: Rail transportation is part of land transportation in Indonesia. The extended rail network has level crossings, namely the crossing of railroads and highways. Judging from the existing laws in Indonesia, the law mentions avoiding accidents at level crossings. Several factors influence law enforcement at railroad crossings, including legal, law enforcement, facilities, community, and cultural factors. There needs to be legal awareness from the side of law violators themselves, law enforcement officers themselves, and the government side. It is also necessary to increase cooperation between networks of law enforcement officers in crossing railroad crossings. Method: The research method used in this study is comparative descriptive. Result: The public is stated to have not understood the regulations that discuss railroad crossings listed in Law Number 23 of 2007, which discusses railways. In Law Number 22 of 2009, which discusses Traffic and Road Transportation, it is stated that Government Regulation 56 of 2009 discusses the Implementation of Railways and Government Regulation Number 72 of 2009 concerning Railway Traffic and Transportation. Conclusion: The law of crossing a railroad plot according to positive law in Indonesia has a position as a reference for travelling a railroad plot as has been written based on: Article 124 of Law Number 23 of 2007, Article 78 of Government Regulation Number 56 of 2009, Article 110 paragraph (1) Government Regulation Number 72 of 2009 & Article 114 of Law Number 22 of 2009.

Improving safety at railroad level crossings is continually conducted to reduce accidents rate at railroad level crossings, especially unguarded official railroad level crossings where accidents often occur. Railroad level crossings are prone to accidents and it mainly caused by accidents that occur at level crossings. Accidents at level crossing are caused by several factors such as human error, crossing guards who are late to lower the barrier, and inferior public awareness to comply with signs at level crossings. This research is located at the railroad level crossing KM 31+988 in Taman District, Sidoarjo. The analysis result shows that the influence factors of people violating the train early warning system are the frequency of random crossings in a day which affects the committing violations with a probability value of 60.72%, and the waiting time before a train passes which takes too long promote committing violations with a probability value of 32 .7%.

The railroad crossing is the intersection of a road with a railroad track. Accidents are the biggest problem at railroad crossings. Factors that cause accidents at railroad crossings, namely breaking through crossing gates, besides that the lack of safety facilities is one of the causes of accidents. To avoid this, it is necessary to review the improvement of safety at railroad crossings. This research on the JPL 75 KM 31+368 railroad crossing uses an analysis of calculating the average daily traffic volume multiplied by the volume of trains that pass, which is 85,407.5 smpk. These results already exceed the technical standard of railroad crossings, namely the volume daily traffic (LHR) is multiplied by the number of train trips that pass per day which is between 12,500-35,000 smpk, then the crossing does not need to be changed to a non-level crossing. Efforts to improve safety that need to be carried out by JPL 75 KM 31 + 368 from the direction of Kalitengah are in the form of safety signs in accordance with the guidelines of the technical standards of safety for a railroad crossing.

Abstract The existence of level crossings between railroads and road vehicles that do not have gates in areas far from crowds, such conditions require gates that are made automatically to avoid accidents. The Automated Railroad Crossing System (ARCS) is an automatically activated railroad crossing gate where train arrival information is obtained through sensors. For one level crossing, there are several electronic devices installed in the automatic railroad crossing system. It is planned that the automatic railroad crossing system will be installed at several level crossings. The problem is how to estimate the time to perform automatic railroad crossing maintenance at several different locations, For this reason, it is necessary to know the estimated remaining useful life (Remaining Useful Life) of the subsystems. The purpose of this research is to find the estimated remaining useful time (RUL) of the subsystem in the automatic railroad crossing system in order to estimate the time to perform maintenance. The process that is carried out to obtain the remaining useful time is through the Prognostic Health Management System development plan, while the analysis of the estimated remaining useful time is carried out using Principle Component Analysis (PCA), the results of this simulation show promising results to determine the estimated value of the remaining useful time. If it can be known the estimated remaining time of the benefit, it is hoped that the maintenance plan for each automatic railroad crossing system can be carried out more efficiently.

One alternative in reducing accidents at railroad crossings without guards is automatic pneumatic railroad crossings. This tool uses PLC (Programmable Logic Controller) as a processing system. Automatic crossing railroad crossing works by using two proximity sensors that are placed on the right and left crossings with a distance far from the crossing (approximately 1 KM). The system outputs are pneumatically actuated sirens, lights and door lintels. At most this door will move up and down closing and opening the crossing. The use of pneumatics in manufacturing because pneumatics saves more space around the crossing and is safe. In testing, detection is done in 2 opposite directions. The results show the tool has been working to close and open crossings with good performance.Salah satu alternatif dalam mengurangi kecelakaan di pintu perlintasan kereta api tanpa penjaga adalah palang pintu kereta api pneumatik otomatis. Alat ini menggunakan PLC (Programmable Logic Controller) sebagai sistem pemroses. Palang pintu perlintasan kereta api otomatis bekerja dengan menggunakan dua buah sensor proximity yang di letakkan pada kanan dan kiri perlintasan dengan jarak yang jauh dari perlintasan (kurang lebih 1 KM). Keluaran sistem berupa aktifnya sirene, lampu, dan palang pintu yang digerakkan dengan pneumatik. Paling pintu ini akan bergerak naik dan turun menutup dan membuka perlintasan. Penggunaan pneumatik dalam pembuatan karena pneumatik lebih menghemat ruang sekitar perlintasan dan aman. Dalam pengujiannya, pendeteksian dilakukan dengan 2 arah yang berlawanan. Hasil menunjukkan alat telah bekerja menutup dan membuka perlintasan dengan kinerja yang baik.

Full textAbstract:
More than 2,000 crashes and 239 fatalities were reported at public passive highway-railroad grade crossings in 1994. Driver error, often due to a breakdown in communication between traffic control devices and the driver, is commonly cited as a factor in passive grade crossing crashes. The objective of this study was to evaluate an improved method for communicating with drivers in an effort to improve safety at passive grade crossings. Specifically, this study evaluated the effectiveness of a vehicle-activated strobe light and supplemental sign as enhancements to the railroad advance (W10-1) warning sign at a passive highway-railroad grade crossing near Temple, Texas. Three study methods were used to evaluate this enhanced sign system including a before and after speed study, a driver survey, and a driver observation study. The results indicated that average speeds on the approaches to the grade crossing were lower after the installation of the enhanced sign system. Drivers responded favorably to the enhanced sign system, and no adverse driver reactions were observed at the onset of the flashing strobe light. The strobe light was effective in directing drivers’ attention to the railroad advance warning and supplemental signs. The enhanced sign system appears to increase driver awareness of the passive grade crossing, cause some drivers to approach the grade crossing with additional caution, and reduce the average speed near the nonrecovery zone on both approaches.

Full textAbstract:
The installation of “active” warning devices, such as crossing signals and gates, is a principal element of state and federal railroad crossing safety programs, and their effectiveness in preventing vehicle–train collision is well documented. While most active crossings are occupied by trains only a few minutes each day, non-crashworthy items are frequently present at active crossings including crossing signal masts, crossing gate mechanisms, cantilever supports, and signal controller bungalows. Various agencies utilize longitudinal guardrail systems to protect errant motorists from striking non-frangible crossing signal hardware. This study sought to determine whether such guardrails influence the prevalence and severity of motor vehicle strikes involving crossing hardware. A review of 10 years of police crash-report narratives in Iowa, United States (U.S.) indicates an average of 15.6 crashes per year at 1,853 crossings involving signal masts, signal guardrails, or related infrastructure. Over this period, one fatality and five serious injuries occurred as a result of these crashes. The crash-injury severity distributions appeared similar in crashes with and without guardrail, and regression models showed that guardrail presence did not affect the rate of crashes involving railroad apparatus. Although the use of longitudinal guardrail systems did not appear to have a strong effect on crash rates or severity at active grade crossings, other methods for reducing crash prevalence and severity could be explored in future research, such as the development of crashworthy signal assemblies for flashing-signal-only crossings and the redesign of gate and cantilever supports to increase separation from the traveled way.

Full textAbstract:
The object of research is pedestrian safety when crossing railroad tracks at pedestrian crossings. A method for improving the safety of pedestrian traffic when crossing railroad tracks within the area approaching the railroad pedestrian crossing has been developed, by introducing an information system for warning pedestrians about train movement with a fixed warning time. Experimental measurements of the speed of the rolling stock were carried out in the area approaching the pedestrian crossing over the railroad track. With the mixed movement of trains, it was found that the lowest speed of the train was 67.46 km/h, and the highest was the passenger train – 131.9 km/h. At the same time, the speed of freight trains ranged from 74 to 79 km/h. Such data are needed to determine the speed of the rolling stock on the approach to the crossing or transition, which will allow the light and sound signal to be turned on in time when the movement of a pedestrian across the track will be dangerous. The methodology for calculating the length of the approach section to the pedestrian crossing, depending on the speed of the rolling stock, has been given. It was established that the speed of the rolling stock has a significant effect on the length of the approach section. At the lowest measured speed of the train – 67.46 km/h, the length of the approach section was 317.46 m, and when the passenger train was moving at a speed of 131.9 km/h – 620.68 m. For a single-track section of the railroad, a fixed time has been established for warning pedestrians about the approach of a train to the crossing. It is a constant value that is included in the warning information system on a single-track section, and after it, a complex light and sound alarm with an information board is activated, which will warn the pedestrian about the movement of the train. The method for improving the safety of pedestrian traffic with a fixed time of the pedestrian’s anticipation of the train movement could be used at crossings with pedestrian traffic, as a supplement to the crossing signaling subsystem in railroad transport. It can also be used at equipped pedestrian crossings over railroad tracks in urbanized areas. The advantage of introducing such a method is a fixed time to warn the pedestrian, in each specific case of the train approaching the crossing

A railroad crossing is an intersection where a railway line crosses a road that can become an accident-prone point. The high number of accidents on a railroad crossing is due to the low level of society’s discipline in traffic. One of the communities who cares about this phenomenon is Edan Sepur Indonesia Community. There were 16.111 violations on 5 railroad crossings in Bandung for the last 6 months of the Crossing Discipline Event 2022. The purpose of this design is to make an interesting media presentation related to railroad crossing discipline that will be socialized to the teenagers aged 15-18 years old in Bandung. The method used on this design is a qualitative method by doing observation, interview and questionnaire. This media presentation design is aimed to provide knowledge and early education concerning the awarness of railroad crossing discipline to prevent accidents.

Full textAbstract:
To understand drivers' decisions and actions at grade crossings, we examined human factors contributing to noncompliance at grade crossings using a sociotechnical framework. This perspective allows driver behavior at grade crossings to be examined not as individual elements but rather as a function of how each element interacts with other elements within the system. In this paper, we present a model that addresses driver decision-making at grade crossings at a systems level. We identify and describe four elements of the grade crossing system influencing driver compliance: the design of the grade crossing environment, driver characteristics, the role of organizations and management, and social and political forces. We then apply the model to identify how failure to consider safety from a systems perspective contributed to the grade crossing accident that occurred in Fox River Grove, Illinois, in 1995.

There are many issues related to highway–railroad grade crossings. For historic and practical reasons, trains have the right-of-way at grade crossings, which results in delays to motorists. In addition, the differential in size, speed, and stopping ability between motor vehicles and trains raises many serious safety concerns. Historically, the methods used to address these delay and safety problems at grade crossings have been reactive in nature. For example, the Manual on Uniform Traffic Control Devices specifies a minimum of 20 s of warning time for active warning devices at grade crossings. Intelligent transportation system (ITS) technology offers potential solutions for increasing the warning time at grade crossings. Advanced on-board devices and off-track detection equipment can allow train position and speed to be monitored. This information can be shared through wireless and wireline telecommunications equipment being deployed for ITS. Transportation management center personnel can then predict the arrival and crossing times of trains at grade crossings. It is hypothesized that if the warning time could reliably be increased, the traffic-operation strategies in the vicinity of grade crossings could be more proactive, reducing delay to motorists and increasing safety for both trains and automobiles. The research focuses on a second-generation technology approach to an advanced prediction of train arrival and crossing (gate-up and gate-down) times at highway–railroad grade crossings, including problems faced at grade crossings, background on detection and prediction technology for grade crossings, the train monitoring system used as the test bed for the research, the development of the methodology, the results of the analysis, and the conclusions of the research and potential applications for the model.

Thailand has a railway system that is available throughout the country, so there are several railroad crossings. These crossings are generally made of concrete or logs with multiple constraints. There are some disadvantages of concrete railroad crossing, such as, crack, noise during car passing over. To overcome these disadvantages, the softer materials should be used instead. Therefore, this research proposes the natural rubber, widely grown throughout Thailand, panel railroad crossing. However, the natural rubber alone is not enough to withstand the harsh condition. Thus, it is necessary to have some addition ingredients that will enhance the natural rubber properties. The material used in this research is a rubber compound between Chloroprene Rubber (CR) 75% and Natural rubber (NR) 25% blend with additives such as carbon black (CB), magnesium oxide (MgO) and sulfur (S8). The objectives of this article were to analyze the deformation of the natural rubber panel railroad crossing and to evaluate its safety factor, defined as the ratio of strain at break and the maximum equivalent strain, using finite element method. In the analysis, the applied loading of the model was obtained from the State Railway of Thailand. The analyzed results reveal that the deflection of rubber panels passes the standard from State Railway of Thailand. Safety factor of external rubber panel is 27.03 and for internal rubber panels are 9.12 and 15.29. The metal pads had elastically deformed and concrete railroad sleeper deformation was very small.

Railroad crossing security on highways is an important issue for road user safety. The current security system still has limitations, such as a lack of timely response and negligence of crossing guards, resulting in a high number of accidents at railroad crossings, which often claim lives. The high rate of accidents that occur today causes safety to be one of the most important things. Therefore, it is necessary to apply sophisticated technology to minimize the risk of accidents. The utilization of computer technology in the railway crossing security system can be an optimal solution. The system will work by using sensors that are able to detect the arrival of trains and send information about the state of the crossing to the crossing guards in real time. Thus, the crossing guards can take appropriate and quick action if there is a malfunction in the system. By integrating advanced technology, it is hoped that accidents at railway crossings can be minimized and the safety of road users can be guaranteed.

Transportation safety must be obeyed by all modes of transportation. The railroad crossing is one point that has the potential for conflict between railroad shares and road users. In accordance with applicable regulations, railroad facilities are prioritized when passing level crossings. In fact, road users often try to break the rules. This research aims to present alternative solutions to improve the safety of road users and railroad lines at cross section level. This research uses a method that begins with a literature study. Next through the design phase, the prototype stage and finally the testing phase. The results of this study are the prototype of the railroad direction detector and the identification of electronic-based railways by using an Arduino Microcontroller. The result shows an LCD board that can provide information to road users for the train's arrival direction and train name. With this information it is expected that road users are more concerned with safety and can be careful when passing a level crossing.

Full textAbstract:
The critical points on the rail and road network are their intersections, i.e., level crossings. During a train crossing, car traffic is stopped. This reduces the fluidity of traffic on the road and, consequently, can cause congestion. The problem increases with the number of cars and trains. Frequently, due to national regulations, level crossing closure times are long. It is mainly dictated by safety issues. Building two-level intersections is not always a good solution, mainly because of the high cost of implementation. In the article, the authors proposed the use of sensors to reduce level crossing closure times and improve the Level of Service on the road network. The analyzed railroad lines are local agglomeration lines, mainly due to safety (low speed of commuter trains) and high impact on the road network. The sensors proposed in the article are based on radar/LIDAR. Formulas similar to HCM methods are proposed, which can be implemented in a railroad crossing controller. Simulations using the PTV Vissim program are carried out and the results are worked out based on the obtained data. The considered method can reduce the level crossing closure time by 68.6%, thereby increasing the Level of Service on roads near railroads.

Due to the high mobility of those passing by and the presence of trains that cross the intersection between the highway and the railroad, also known as level crossings, Jalan Hasanudin experiences heavy traffic during rush hour. Additionally, because of the large volume of train traffic at the Poncol station and the proximity of this intersection to the station, there is frequently a buildup of vehicles at the level crossing on Jalan Hasanudin. As a result, researchers will determine how Jalan Hasanudin Semarang performed. After conducting research, it was discovered that the highest vehicle queue length occurred on Monday, February 27 2023 from Jalan Hasanudin - Imam Bonjol at closing time 16.45 with a queue length of 123 meters and the highest stop delay occurred on Saturday, March 4 2023 from the direction of Jalan Hasanudin - Imam Bonjol with an average stop delay duration of 372.00 seconds. Therefore, the occurrence of long lines led to fuel losses for the drivers; their total gasoline loss over the course of the three research days was IDR 886,550.7. The researchers offer recommendations based on the findings of the research analysis to control street vendors and people near railroad tracks and railroad crossings that result in side barriers and long lines during stop delays, install traffic signs like those that prohibit stopping, prohibit parking, and prohibit raising and lowering passengers on roads, and so that there is no congestion along Jalan Hasanudin and around railroad crossings.

Level crossing, also known as railroad and highway crossings, pose a risk to those who use both modes of transport due to collisions that may occur. This risk associated with level crossings is of great importance both in Turkey and in the world. In this study, data envelopment analysis was performed on the accident data occurring on five types of level crossings in Turkey and a measurement of safety performances of level crossings in Turkey was provided. As a result of the analysis, the most efficient three-level crossings were found to be Hilal-Bandırma in Manisa, Samsun-Kalın in Amasya_1, and Samsun-Kalın in Amasya_2. In addition, a linear regression model that serves with the variables which are the components of level crossing and the number of accidents is established. In this model, it is seen that the ratio of independent variables to dependent variables was statistically significant.

Full textAbstract:
Railroads are a critical part of the United States’ transportation sector. Over 40 percent (by weight) of the nation’s freight is transported by rail, and according to the Bureau of Transportation statistics, railroads moved $186.5 billion of freight in 2021. A vital part of the freight network is railroad bridges, with a good number being low-clearance bridges that are prone to impacts from over-height vehicles; such impacts can cause damage to the bridge and lead to unwanted interruption in its usage. Therefore, the detection of impacts from over-height vehicles is critical for the safe operation and maintenance of railroad bridges. While some previous studies have been published regarding bridge impact detection, most approaches utilize more expensive wired sensors, as well as relying on simple threshold-based detection. The challenge is that the use of vibration thresholds may not accurately distinguish between impacts and other events, such as a common train crossing. In this paper, a machine learning approach is developed for accurate impact detection using event-triggered wireless sensors. The neural network is trained with key features which are extracted from event responses collected from two instrumented railroad bridges. The trained model classifies events as impacts, train crossings, or other events. An average classification accuracy of 98.67% is obtained from cross-validation, while the false positive rate is minimal. Finally, a framework for edge classification of events is also proposed and demonstrated using an edge device.

Several feature paths running adjacent to the railroad tracks, and crossing a highway; they serve urban areas, recreational activities, light rail station access, and a variety of other purposes. Some of these crossings see a disproportionate number of violations and conflicts between rail, vehicles, and pedestrians and bikes. This research focuses on developing a methodology for appropriately addressing the question of treatments in these complex, multimodal intersections. The methodology is designed to be able to balance a predetermined, prescriptive approach with the professional judgment of the agency carrying out the investigation. Using knowledge and data from the literature, field studies, and video observations, a framework for selecting treatments based on primary issues at a given location is developed. Using such a framework allows the agency to streamline their crossing improvement efforts; to easily communicate and inform the public of the decisions made and their reasons for doing so; to secure stakeholder buy-in prior to starting a project or investigation; to make sure that approach and selected treatments are more standardized; and to ensure transparency in the organization to make at-grade crossings safer for pedestrians and bicyclists, without negatively impacting trains or vehicles.

State programs in grade crossing safety are an important and successful traffic safety initiative. Their cost-benefit ratios are close to those achieved on all other highway safety projects. Estimates suggest these railroad crossing improvements have contributed to an 88 percent reduction in fatalities and a 62 percent reduction in injuries. While these achievements were obtained through the combined efforts of railroad companies and federal, state, and local governments, the primary responsibility for carrying out the program has fallen upon the states. States have developed individual procedures in identifying and improving high-risk grade crossings. These procedures, which constitute a naturally collaborative process, often lead to long periods of time between the initial identification of high-risk crossings and the physical installation of improvements. Most states either have initiated action or are considering procedural changes to reduce these times. One particularly beneficial action is a status tracking procedure. Described here is a computerized office support system that combines status tracking and reporting capability with the ability to produce system-compiled documents necessary for the functioning of the office. Alabama's Multimodal Office Support System (AlaMOSS), is designed to improve the productivity and effectiveness of Alabama's grade-crossing safety program.

The limited number of air quality sensors causes the presentation of Air Quality Index information to be not optimal. In principle, the installation of Air Quality Index sensors can provide input in air quality control and monitoring policies in an area. However, some places that have the potential to become local tourism or gathering places such as around the railroad crossing area do not have air quality sensors installed. Wind speed when trains pass can cause dust to scatter. Therefore, it is necessary to conduct further studies related to air quality around railroad crossings. Therefore, this research proposes to analyze and monitor air quality around railroad crossings in the Special Region of Yogyakarta based on the Internet of Things. In this study, the installed sensors functioned to monitor air quality at 3 locations that have different characteristics so that the data generated is also different. Based on the PM25 sensor, the air quality is categorized as Good 50% and Moderate 50%, while the PM10 sensor is categorized as Good 80% and Moderate 30%. The Internet of Things sensor built in this study is still not integrated in its recording between wind speed and air quality.

Implementation of Innovative Technologies During The Modernization of Existing Level Crossings for High-Speed Train Traffic Purpose. The main purpose of the study is to review innovative technologies for improving safety at the intersection of railways and roads. The object of research is the processes of functioning – railway crossings with different intensity and parameters of traffic, which require solving a fairly wide range of theoretical, practical and organizational tasks. Methodology. The study is based on the theory of mathematical modeling and numerical methods of computer calculations. The subject of the study is indicators that allow to assess the state of safety after modernization or new design solutions. Findings. A model of an improved method of the final coefficient is proposed, which allows predicting changes in the initial data and obtaining different values of the final coefficient, and thus planning measures to introduce innovative technologies that improve traffic safety at level crossings. Closing railroad crossings or switching to a two-level intersection of railroad and road (overpasses) is the only way to completely eliminate the risk. However, it is virtually impossible to close all railroad crossings immediately. In addition to financial and practical constraints, user convenience should still be a key factor. Using hierarchy, brainstorming, and other methods, a reliable set of indicators can be identified to assess and ensure the overall safety of passengers and vehicles related to all aspects of the design, construction, maintenance, and operation of the rail network. The introduction of innovative technologies during the modernization of existing level crossings is an important step towards organizing high-speed train traffic. These technologies will increase the level of traffic safety at railroad crossings and protect people's lives. Originality. The scientific and applied problem of introducing innovative technologies during the modernization of existing level crossings for the organization of high-speed train traffic has been solved. Practical value. The implementation of a sound technology for the modernization of existing level crossings will provide a significant increase in traffic safety and throughput.

Full textAbstract:
Traditionally, locomotive engineers begin sounding the train horn approximately one-quarter mile from the crossing to warn motorists and pedestrians approaching the intersection. To be heard over this distance, the train horn must be very loud. This combination of loud horns and the length along the tracks that the horn is sounded creates a large area adversely impacted by the horn noise. In urban areas, this area likely includes many nearby residents. The automated-horn system provides a similar audible warning to motorists and pedestrians by using two stationary horns mounted at the crossing. Each horn directs its sound toward the approaching roadway. The horn system is activated using the same track–signal circuitry as the gate arms and bells located at the crossing. Once the horn is activated, a strobe light begins flashing to inform the locomotive engineer that the horn is working. Horn volume data collected near the crossings clearly demonstrate the significant reduction of land area negatively impacted by using the automated horns. Residents overwhelmingly accepted the automated-horn systems and noted a significant improvement in their quality of life. Motorists preferred the automated-horn systems, and locomotive engineers rated these crossings slightly safer compared with the same crossings in the before (train horn) condition.

Accidents at highway-rail grade crossings can cause fatalities and injuries, as well as significant property damages. In order to prevent accidents, certain upgrades need to be made at highway-rail grade crossings. However, due to limited monetary resources, only the most hazardous highway-rail grade crossings should receive a priority for upgrading. Hence, accident/hazard prediction models are required to identify the most hazardous highway-rail grade crossings for safety improvement projects. This study selects and evaluates the accident and hazard prediction models found in the highway-rail grade crossing safety literature to rank the highway-rail grade crossings in the State of Florida. Three approaches are undertaken to evaluate the candidate accident and hazard prediction models, including the chi-square statistic, grouping of crossings based on the actual accident data, and Spearman rank correlation coefficient. The analysis was conducted for the 589 highway-rail grade crossings located in the State of Florida using the data available through the highway-rail grade crossing inventory database maintained by the Federal Railroad Administration. As a result of the performed analysis, a new hazard prediction model, named as the Florida Priority Index Formula, is recommended to rank/prioritize the highway-rail grade crossings in the State of Florida. The Florida Priority Index Formula provides a more accurate ranking of highway-rail grade crossings as compared to the alternative methods. The Florida Priority Index Formula assesses the potential hazard of a given highway-rail grade crossing based on the average daily traffic volume, average daily train volume, train speed, existing traffic control devices, accident history, and crossing upgrade records.

How effective is the horn on trains in alerting motorists, cyclists and pedestrians of the approach of a train to a highway-railroad crossing? Road users become aware of trains approaching crossings either by seeing them, hearing the warning horn or by warning devices at the crossing. Auditory warnings have some advantages over others, but practical problems of sound transmission and the noise environment of road users limit their effectiveness. Factors that affect the audibility of train horns and crossing bells are discussed. Train and crossing bells are generally effective for persons in their immediate environment, but are relatively ineffective for occupants of closed vehicles. Because of the lack of reliability of the detectability of auditory warning signals provided to motorists and others approaching rail-highway crossings, they should visually scan the tracks to ascertain the presence of a train.

An evaluation was performed of special X-box pavement marking configurations at railroad–highway grade crossings, originally used in several European countries. The intent is to provide motorists with supplemental visual cues about whether sufficient space is available for safe storage of a vehicle beyond the track for a motorist to proceed across. It is intended for application where nearby intersections can cause queues to back up to the track. These conspicuous markings, configured as an X in a box, were tested at two Florida locations, one in an urban area and one in a rural area, over a 1 ½-year period. The rates of cars hazardously stopping on or closely adjacent to the railroad tracks at the crossings were compared under pre- and postinstallation conditions. Results at the rural location showed a decline of more than 60% in hazardous stoppage rates over an extended period. No significant differences were found between the pre- and postinstallation tests at the urban location. A control site was utilized near the crossing in the urban location, and it showed no significant differences between the two test periods that were concurrent with the analysis at the treated site. Recommendations are provided for application of these markings at grade crossing sites in rural and urban locations.

Railroad level crossings are potential points that are prone to serious accident risks. As transportation infrastructure grows, the importance of safety at level crossings increases. The accident prediction equation developed by the United State Department of Transportation (U.S. DOT) is one of the most frequently used formulas due to its accuracy in predicting the number of accidents at level crossings. In this study, the calculation of hazard index and hazard index and probability of accidents for the next few years using the U.S. DOT formula approach at level crossings located in Madiun City, namely JPL 1, JPL 136 and JPL 138. Based on the results of the Hazard Index calculation, JPL 136 has the highest hazard index value of 194.859 followed by JPL 138 and JPL 1. The results of accident predictions for the next three years at both JPL 1, JPL 136 and JPL 138 are likely to occur 2 accidents at the crossing.

Railway and road transportation are land transportation that service users widely use because these modes play an important role in community activities, especially people on the island of Java. The train is a mass transportation with many advantages over other transportation, especially as a solution to the congestion problem in the country. Level crossing is a meeting between the railroad and the highway. Level crossings must meet the standard requirements set by the relevant agencies including geometric conditions, free space and wake space, and visibility so that level crossings are comfortable and safe for vehicles to pass through. The purpose of this study is to evaluate the geometric conditions, free space and shape as well as the visibility of level crossings. This study uses field observations and data from DAOP 7 Madiun to compare field conditions with requirements. The research was conducted at level crossings, namely JPL 136 and JPL 138 Kota Madiun.

At-grade highway–railroad crossings cause traffic control problems that have a bearing not only on traffic safety but also on traffic flow efficiency. Crossings located near freeway exits pose particularly acute problems, as long closures could result in vehicle queues that spill back onto freeway lanes. A potential solution to this problem was evaluated by investigating the use of variable message signs to divert exiting freeway traffic through non-congested alternate exits. This was done using the crossing near the Fredericksburg Road exit on Interstate 10 (I–10) in San Antonio, Texas, as a case study. In the evaluation, microscopic simulation was used to determine the impacts of train operations at the crossing and the potential benefits of a variable-message sign (VMS) system installed on I–10. These effects were gauged by considering scenarios with varying levels of train duration, traffic demand on the freeway exit, and driver compliance to the displayed messages. While little network improvements were obtained, the analysis demonstrates the capability of the INTEGRATION software in analyzing such scenarios and the extent to which exiting freeway traffic may benefit from the VMS system, as well as the need to consider fuel consumption and vehicles emissions in the evaluations.

Safety at railroad grade crossings is a critical issue for highway and rail networks. Relevant databases can be analyzed to find the causes of or factors contributing to crossing accidents so that appropriate counter-measures can be applied. Manually establishing the order of the contributing factors of the accidents and extracting useful information from accident databases are not feasible because of the enormous number of possible permutations of contributing factors. This paper presents a new automated method for sorting and clustering accident attributes to identify and visualize trends in the accident databases. The method is called modified nested sorting and crossing cluster (M+C). The method creates a dynamic tree visualization that highlights attributes resulting in the greatest accident concentration along a tree branch, uncovering the most common nested accident factors. This approach is a significant improvement over static methods that rely on a fixed hierarchy of attributes. With the M+C method, a unique hierarchy of the attributes can be determined for a single crossing or for a set of crossings. This approach is completely data driven and is suitable for corridors and large groups of accidents that are otherwise difficult to analyze. The method is illustrated for single crossings and a corridor with several crossings identified from the FRA online database. Absolute sorting and nested sorting are discussed, and the evolution of M+C is presented. The M+C method is useful for assessing many single grade crossings or crossings that are along a corridor or within a region.

The volume of video data in the railroad industry has increased significantly in recent years. Surveillance cameras are situated on nearly every part of the railroad system, such as inside the cab, along the track, at grade crossings, and in stations. These camera systems are manually monitored, either live or subsequently reviewed in an archive, which requires an immense amount of human resources. To make the video analysis much less labor-intensive, this paper develops a framework for utilizing artificial intelligence (AI) technologies for the extraction of useful information from these big video datasets. This framework has been implemented based on the video data from one grade crossing in New Jersey. The AI algorithm can automatically detect unsafe trespassing of railroad tracks (called near-miss events in this paper). To date, the AI algorithm has analyzed hours of video data and correctly detected all near-misses. This pilot study indicates the promise of using AI for automated analysis of railroad video big data, thereby supporting data-driven railroad safety research. For practical use, our AI algorithm has been packaged into a computer-aided decision support tool (named AI-Grade) that outputs near-miss video clips based on user-provided raw video data. This paper and its sequent studies aim to provide the railroad industry with next-generation big data analysis methods and tools for quickly and reliably processing large volumes of video data in order to better understand human factors in railroad safety research.

Crashes at Highway–Rail Grade Crossings (HRGCs) that involve a truck or a train carrying hazardous materials (hazmat) expose people and the environment to potentially severe consequences of hazmat release. This research involved statistical modeling of the probability of hazmat release from trucks and/or trains in crashes at HRGCs to identify factors associated with hazmat release. The Federal Railroad Administration (FRA) HRGC crash dataset (2007–2016) yielded two subsets of crashes: 1) those involving hazmat-carrying trucks, and 2) those involving hazmat-carrying trains. Results from a logistic regression model using data subset 1 (crashes involving hazmat-carrying trucks) with hazmat release/no release as the response variable showed that standard flashing signal lights, railroad crossbucks, and railroad classes II and III (relative to railroad class I) were associated with lower hazmat release probability from hazmat-carrying trucks. Hazmat release probability from trucks was higher with freight train involvement. Results from a logistic regression model using data subset 2 (crashes involving hazmat-carrying trains) revealed that hazmat release probability from trains was lower with warmer temperature. However, the probability of release from trains was greater with railroad class II (relative to railroad class I), type of highway user (different types of trucks and motorcycle relative to automobiles), and weather conditions (fog, sleet or snow, relative to clear). A comparison of the results from this study with HRGC crash severity studies highlighted the importance and usefulness of this study.

Vehicle-train collisions at Highway-Rail Grade Crossings continue to be a safety concern and despite improvements in warnings, many of these incidents are attributed to human error. In some cases, distractions other than railroad traffic, such as nearby highway intersections, may create additional burdens for drivers’ decision making. In this study, we systematically examined safety concerns across two types of Highway-Rail Grade Crossings: non-short storage and short-storage. In a controlled experiment, 48 college-aged drivers viewed a series of driving scene images and identified, rated, and explained up to five safety concerns in each image. Participants reported more safety concerns and higher average severity of those concerns for short-storage rail crossings than non-short storage, but these findings did not depend on rural vs. urban driving experience. Content analysis of the 1,230 safety concerns using chi-squared analysis revealed differences in attention to dynamic safety concerns by rail crossing type, but not to static concerns.

The study aims to find the most suitable regression model of railroad level crossings accident data to obtain factors significantly affect the number of fatalities in DAOP VII Madiun. The variables used were road width, right slope, left slope, train frequency, type of crossing, large kilometer angle of view, small kilometer angle of view, Early Warning System, road status, type of crossing gates, left and right caution sign, and rumble band markings. The study used comparing method between the results of the Poisson regression model and the Negative Binomial regression model. It is found that the Negative Binomial regression model has a smaller Akaike Information Criteria and Root Mean Square Error than the Poisson model. It can be concluded that the Negative Binomial regression model is a better choice in modeling accident data in DAOP VII Madiun level crossing. Based on the modeling result, the factors significantly affect the number of fatalities in level crossings accident are road width, road status, type of crossing gate, and the presence or absence of caution signs.

This research aims to make a warning light with a microcontroller base as a control system. With the aim of reducing the use of manual systems in general that are in use today. The advantage of this warning light control system is that it functions to reduce the number of accidents that occur and can be used for railroad crossings where there are still no latches that have not been installed on the railroad railroad crossing (wild road). The display of the work system that is made will be monitored using a web monitoring display that supports and is easy to understand. Even though it has some delay in the process, the planned system has run well based on the average delay value. The experimental results show the average delay measured in the system is 0.31 seconds before sending from the node and 0.49 seconds when there is a change in conditions, while when there is data transmission from the node. The measured packet loss on the system is 0% before transmission and fans and 8.88% when data is transmitted from the node.

The paper aims to investigate objects located in railway natural industrial complexes, e.g. the Kuybyshevskaya Railway within the boundaries of Samara region. The authors analyse its following characteristic properties: geometric (proximity to water bodies); intercepted (crossings with bridges or waterbodies); watercut (proximity to subsurface water outlets and high groundwater); hilly-mountainous terrain (washouts and washaways); violation of surface (water drainage from the walls, washaways of flood-prone slopes). The researchers studied a schematic map of the Kuybyshevskaya Railway and came to the conclusion that there is a considerable number of railways crossings with water objects in Samara region, Ulyanovsk region and the Republic of Tatarstan. Some of these railways crossings are located in close proximity to waterbodies. The average value of the crossings is 0.549 km for every 1 km, i.e. approximately every 500 m railway tracks cross at least one water object. It means that there is a surface run-off coming from railroad tracks and near-by territories into a waterbody every 500 m. Systematic monitoring of water pollution is performed by a considerable number (up to 20) of gauging stations located within all railroad tracks in Samara region.

The number of accidents at level railway crossings, especially crossings without gate barriers/attendants, is still very high due to technical problems, driving culture, and human error. The aim of this research is to provide road maps application based on ergonomic visual displays design that can increase awareness level for drivers before crossing railway crossings. The double awareness driving (DAD) map information system was built based on the waterfall method, which has 4 steps: defining requirements, system and software design, unit testing, and implementation. User needs to include origin-destination location, geolocation, distance & travel time, directions, crossing information, and crossing notifications. The DAD map application was tested using a usability test to determine the ease of using the application used the System Usability Scale (SUS) questionnaire and an Electroencephalogram (EEG) test to determine the increase in concentration in drivers before and immediately crossing a railway crossing. Periodically, the application provides information on the driving zone being passed; green zone for driving distances > 500 m to the crossing, the yellow zone for distances 500m to 100m, and the red zone for distances < 100 m. The DAD map also provides information on the position and speed of the nearest train that will cross the railway crossing. The usability test for 10 respondents giving SUS score = 97.5 (satisfaction category) with a time-based efficiency value = 0.29 goals/s, error rate = 0%, and a success rate of 93.33%. The cognitive ergonomic testing via Electroencephalogram (EEG) produced a focus level of 21.66%. Based on the results of DAD map testing can be implemented to improve the safety of level railroad crossings in an effort to reduce the number of driving accidents.

Research quality railroad crossings with under sleeper pad. The quality of the railway track is infl uenced by a number of factors, such as durability, reliability, swelling and cost. The article made use of impact assessment under sleepers pad (USP) on the quality of rail track. The author has presented laboratory research, computer research and dynamic study of turnouts with USP. The impact of the USP on the quality of turnouts was assessed. Research results have shown an increase in the quality of turnouts with USP.

Full textAbstract:
Railroad Crossing Guard, commonly known as Penjaga Perlintasan Kereta Api (PJL), has a task in safeguarding the railroad crossing. In carrying out their task, PJL needs to communicate with other PJL and Train Dispatcher (PPKA) in the working area. Therefore, communication plays a critical role in the safety aspect. In 1987, the worst train accident happened in Indonesia’s history of railways, which was caused by miscommunication as the main factor of this accident. This study aims to improve communication skills for all PJL staff in Indonesia to achieve safety at railroad crossings. This study used primer data obtained from questionnaires distributed to 97 PJL individuals under Transportation Department (Dishub) and 97 PJL individuals under PT KAPM. Nowadays, PJL in Indonesia is under Dishub and PT KAPM. The sample was determined using Lemeshow’s formula because the number of subjects from previous studies was unknown or data on the exact number of all PJL in Indonesia was unavailable. Data were analyzed using descriptive and inferential statistics with the Man Whitney U test. PJL under the Transportation Agency and PJL under PT KAPM did not understand the importance of recording communication when maintaining a railroad crossing. The Mann-Whitney U test inferential statistics analysis indicates that the hypothesis was accepted, namely differences in communication skills between PJL under Dishub and PJL under PT. KAPM. The average ranking value was obtained from the total comparison value of all variables from PJL of Dushub and PJL of PT KAPM, with the Mann- Whitney U test results was 79.90 and the average ranking value of PJL under PT. KAPM was 113.10.
