Full textAbstract:
The purpose of this study was to determine the traffic congestion that occurred on the Wonokusumo road in 2020. This study uses a method that refers to the calculation of congestion rates. In accordance with observations in the field on roads with 2/2 UD type two-lane road - two directions are not divided, with a road width of 6 meters for a total of 2 directions with shoulder shoulders 1 meter each on the right and left. The facilities on these roads are not fully equipped with traffic signs such as (no stops, no parking, no speed limit). The highest average daily traffic volume on these roads from 07.00 - 18.00 is 1606 vehicles / hour. The most dominant motorbike type of vehicle passes the road section. From the analysis of the level of congestion conducted obtained results, the side barriers on the road are categorized as moderate (M) by 396 events / hour. Congestion occurs because of crowded activities and vehicles reduce speed and stop beside the road. This causes the service value on the road section is D shows that the vehicle flow is obstructed, the speed is low and the volume of the vehicle is above capacity. Therefore the role of the government is very important to reduce the level of congestion that occurs and motorists are more orderly in carrying out activities on these roads. This causes the service value on the road section is D shows that the vehicle flow is obstructed, the speed is low and the volume of the vehicle is above capacity.

Full textAbstract:
As the first step to obtain a city urban area noise map of road traffic noise, sound power levels of vehicles on the roads should be accurately estimated over a wide area. In Japan, ASJ RTN-Model 2018 was proposed as the representative road traffic noise prediction model, and by using the model sound power level of a vehicle can be determined if the vehicle type, traveling speed, and driving mode are known. As such data on urban road network, the Ministry of Land, Infrastructure and Transport of Japan publishes the road traffic census including road traffic volume and travel speed of major roads in Japan. The data, however, is limited to major roads and there is no data on minor roads. In this study, to estimate noise condition and situation on arbitrary road, a method for estimating the traveling speed and the traffic volume of vehicles on the road from aerial photographs was examined. Road traffic noise levels along several roads in Tokyo were analyzed by the proposed method and the validity of the calculation results were verified by comparing with short-time measurement results obtained along the target roads.

Full textAbstract:
For decades, various algorithms to predict traffic flow have been developed to address traffic congestion. Traffic congestion or traffic jam occurs as a ripple effect from a road congestion in the neighbouring area. Previous research shows that there is a spatial correlation between traffic flow in neighbouring roads. Similar traffic pattern is observed between roads in a neighbouring area with respect to day and time. Currently, time series models and neural network models are widely applied to predict traffic flow and traffic congestion based on historical data. However, studies on relationships between road segments in a neighbouring area are still limited. It is important to investigate these relationships because they can assist drivers in avoiding roads which are impacted by road congestion. Also, the result can be used to improve the accuracy of prediction of traffic flow. Hence, this study investigates relationships of roads in a neighbouring area based on similarity of traffic condition. Traffic condition is influenced by number of vehicles and average speed of vehicles. In our study, clustering method is used to divide the speed of traffic into four (4) categories: very congested, congested, clear and very clear. We used k-means clustering method to cluster condition of traffic flow on road segments. Then, we applied the k-Nearest Neighbour (k-NN) method to classify the traffic condition in neighbouring roads. From the classification of traffic condition in neighbouring roads, we then determine the relationship between road segments. We presented the road with highest relationship on the map and used it as input factor to predict traffic speed of the road using neural network. Results show that combination of k-means and k-NN method produced better results than using both, correlation method and using the k-means method only.

AbstractAmphibians are the group of animals suffering particularly from the presence of roads and vehicle traffic. The seasonal migration to breeding places undertaken by amphibians in the temperate climate zone is the main reason for their appearance on roads. Between June 2001 and August 2003, 957 common toads Bufo bufo were recorded killed on 48.8 km road network with various traffic volumes (350-10500 cars per 24 h), situated in the agricultural landscape of south-western Poland. The highest mortality was recorded in April (57% of all road-kills). The places with highest recorded mortality varied markedly throughout the year. In spring, many more animals died within the built-up areas, while in summer and autumn their number increased in the open countryside. During the whole study period, 73% of all road-kills were recorded on roads (55% of all controlled) with the lowest traffic volume (350-470 cars per 24 h). The average number of road-kills on roads with the high traffic volume (5700-10500 cars per 24 h) was over 15 times lower than on the roads with low traffic (0-0.17 road-kills per 100 m on roads with high traffic vs 2.59 road-kills per 100 m on roads with low traffic). The number of road-kills on 15 road sections was most closely related to the abundance of local populations of Bufo bufo and to the size of water bodies situated in the road vicinity. The yearly level of local mortality in breeding populations of Bufo bufo due to the vehicle traffic ranged from 2 to 18%.

Full textAbstract:
For large and medium-sized cities, the planning and development of urban road networks may not keep pace with the growth of urban vehicles, resulting in traffic congestion on urban roads during peak hours. Take Jinan, a mid-sized city in China’s Shandong Province, for example. In view of the daily traffic jam of the city’s road traffic, through investigation and analysis, the existing problems of the road traffic are found out. Based on real-time, daily road traffic data, combined with the existing road network and the planned road network, the application of a road intelligent transportation system is proposed. Combined with the application of a road intelligent transportation system, this paper discusses the future development of urban road traffic and puts forward improvement suggestions for road traffic planning. This paper has reference value for city development, road network construction, the application of intelligent transportation systems, and road traffic planning.

Traffic congestion is a major issue of Asian megacities which causes the irritation, anger and frustrations among drivers and owners of vehicles during driving in these cities. This paper aims at understanding traffic congestion issues from the perception and experiences of car drivers and owners and their satisfaction level concerning accessibility of circulation within urban roads of Karachi. The issues addressed in this respect are road construction, traffic flow, road crossing, shopping malls along roads, traffic blockage due to VIP movement, congestion during school timing, animal presence on roads, traffic police behavior, marriage halls along the roads, peak hour traffic jams, traffic jams during sociopolitical and religious rallies, road disputes, traffic congestion due to young inexperienced drivers, alternate road availability and pedestrian bridges. The method of investigating these issues is through 42 questionnaire surveys with car drivers and car owners from June to October 2018 on urban roads of Karachi. The analysis of feedback from respondents showed that, more than 90% respondents were satisfied with construction of pedestrian bridges and annoyed with sociopolitical and religious rallies on main urban roads. More than 80% respondents were satisfied with marriage halls along the roads, felt congestion during peak hours and preferred alternate routes to go home. More than 70% agreed that, young and inexperienced drivers cause traffic congestion and felt unsatisfied and displeased with disputes on the streets among residents, traffic police and drivers. More than 60% respondents were satisfied with the road construction but annoyed with VIP protocol and felt congestion during school timings and quite uncomfortable while crossing the road. More than 50% respondents were unsatisfied with shopping malls on both sides of the road, presence of animals on main roads and behavior of traffic police during traffic jams. Finally, concerning traffic flow the respondents were equally divided in their perception. Thus this research presents a detailed perspective of people regarding traffic congestion issues in Karachi for the appropriate response by decision makers of urban transport planning and urban traffic management institutions in city.

Introduction. The issue of road traffic safety has been studied by many modern scientists. However, despite the research, this issue remains relevant to this day, both theoretically and practically. This is due to the fact that the concept of road traffic safety is not currently enshrined in law, and there is no unanimity among scientists on its content. Moreover, the relevance of the practical component is evidenced by the fact that over the past three years a number of important regulations in the field of road traffic safety and procedures for their implementation have been developed. The purpose of the paper is to determine the state of road traffic safety in Ukraine. In accordance with the goal, the main objectives of this study are to formulate a definition of “traffic”, “road traffic safety”, outlining their elements; determining the state of road traffic safety in Ukraine and further development trends, establishing the main directions of implementation of state policy in the field of road traffic safety. Results. Covering the issue of road safety, it should be noted that the current legislation of Ukraine does not provide a definition of this concept, but in 2016 there was an attempt to legislate both the legal category of “road traffic safety” and a number of closely related to it. Thus, the authors of the draft Law on Road Traffic and Safety defined traffic as “the process of traffic on roads and other places where it is not prohibited by the draft law”, and road traffic safety as “a state of the road system, due to which the appropriate level of protection of road users from road accidents and their negative consequences is determined and achieved”. It should be emphasized that road traffic safety is achieved through the application of appropriate measures of organizational, administrative, socio-economic and technical nature, which are enshrined in regulations and which are aimed at ensuring the proper and safe level road traffic safety for all its participants. It should be noted that neither the Ukrainian legislator nor the state executive bodies reduce the state of danger on the roads of Ukraine, so they are constantly developing appropriate programs and taking measures to increase the level of road traffic safety. Thus, in 2020, a state program was approved, the main goal of which is to reduce the level of accidents on the roads and the severity, first of all, of the socio-economic consequences of road accidents. Conclusion. According to the legislation of Ukraine, road traffic safety should be understood as a set of socio-economic and organizational-technical measures to ensure road traffic safety and road user, prevention of road traffic accidents and elimination or minimization of their negative consequences.

The article explores the driving conditions for determining the demand of drivers of vehicles for the movement of roads, the road conditions of which should ensure this demand. The object of the study is automobile international and national transport corridors. When optimizing the management of the complex transport system «International, national and local traffic flows - Automotive International and National Transport Corridors» (MNMTP-AMNTC) can be sought to achieve different goals (criteria of optimality), and, depending on these goals, consider the different tasks of optimal management. On road transport, including in this concept of the system of communication routes (highways), the following tasks are the most important: ensuring the least time of communication at limited road costs; - ensuring the specified time of communication at the lowest road costs; - ensuring the lowest transport costs at a limited level of road costs; - ensuring the lowest road costs at a limited level of transport costs; - ensuring the maximum possible level of traffic safety at a limited level of road costs; - ensuring the required level of traffic safety at the lowest road costs; to achieve a minimum of road costs, provided that the specified volume of traffic (traffic), the specified speed and the necessary safety of traffic; ensuring maximum road capacity at a limited level of road costs. According to its parameters, the MMMTP-AMNTC refers to complex systems, the main characteristics of which are: efficiency indicator; stability; obstruction; Reliability. The newest approach of the «Traffic Triad» will allow to evaluate the functioning and ensure the rational management of any transport system with a focus on meeting the needs of users of highways - road users.

Road safety and measures to ensure it are a priority area of our state’s activity in view of the content of Article 3 of the Constitution of Ukraine, where a person, his life and health, safety are recognized as the highest social value in Ukraine. Reducing the number of accidents, reducing the severity of the consequences of traffic accidents, and especially reducing road accidents with fatalities to a minimum is the main task of specialists who are engaged in improving road safety. Traffic lights are one of the main components of road infrastructure, they are an optical signaling device designed to regulate traffic vehicles and pedestrians on roads and railway crossings. It is this device that regulates the movement of vehicles and pedestrians on the roadway and helps to avoid traffic accidents. Today, the traffic light has entered our lives so much that it is even difficult to imagine how it is possible to regulate traffic flows and ensure the safety of pedestrians on the roads without it. Adaptive or so-called “smart traffic lights” are considered the most modern type of traffic light regulation. Smart traffic lights are modern equipment that allows you to measure the intensity of traffic at the intersection and quickly, in real time, change regulation programs to reduce traffic jams. Artificial intelligence itself analyzes flow parameters, time and date, intensity to improve traffic. It is worth noting that despite the obvious advantages, smart traffic lights will not be able to completely solve the problem of traffic jams, but they will help to partially solve the problem of traffic accidents and support the ecological situation, since the level of emissions of harmful substances into the atmosphere is reduced thanks to the smooth movement of traffic.

Abstract Road inspection regularity and existing types made by road maintenance crew have not been good enough to be aware what is really happening on the roads. Road users' contribution in road traffic safety is very important to ensure fast reaction on different road hazards. It is important to ensure not only the most common ways to report road hazards on state roads by phone, by email and on social media, but also expand data sources options in modern and user-friendly way. Waze navigation application already had functionality to report road hazards – to warn other application users, but no one acted to solve these road hazards until someone reported them through existing communication channels supported by Latvian State roads or Latvian road maintainer. To ensure better road traffic safety and faster reaction time on road hazards solving, Latvian road maintainer gained access to Waze report feed, and, in corporation with Riga Technical university, made a system for analysing and processing Waze data. As the result - Latvian roads maintainer can improve road safety by faster reaction to road hazards reported by Waze users. Today, up to 70 % from total reports processed by Latvian road maintainer are generated by Waze.

Road speed is an important indicator of traffic congestion. Therefore, the occurrence of traffic congestion can be reduced by predicting road speed because predicted road speed can be provided to users to distribute traffic. Traffic congestion prediction techniques can provide alternative routes to users in advance to help them avoid traffic jams. In this paper, we propose a machine-learning-based road speed prediction scheme using road environment data analysis. The proposed scheme uses not only the speed data of the target road, but also the speed data of neighboring roads that can affect the speed of the target road. Furthermore, the proposed scheme can accurately predict both the average road speed and rapidly changing road speeds. The proposed scheme uses historical average speed data from the target road organized by the day of the week and hour to reflect the average traffic flow on the road. Additionally, the proposed scheme analyzes speed changes in sections where the road speed changes rapidly to reflect traffic flows. Road speeds may change rapidly as a result of unexpected events such as accidents, disasters, and construction work. The proposed scheme predicts final road speeds by applying historical road speeds and events as weights for road speed prediction. It also considers weather conditions. The proposed scheme uses long short-term memory (LSTM), which is suitable for sequential data learning, as a machine learning algorithm for speed prediction. The proposed scheme can predict road speeds in 30 min by using weather data and speed data from the target and neighboring roads as input data. We demonstrate the capabilities of the proposed scheme through various performance evaluations.

A model for managing the system "road conditions - traffic flows" is proposed that allows to ensure the functioning of the complex "driver - car - road - environment" in any weather and climate conditions. The analysis of the proposed model and target functional shows that optimization of the "road conditions - traffic flow" system can proceed in many directions, the main of which are: optimal development and placement of the network of forest roads, improving their technical level and level of maintenance, road engineering equipment , efficient traffic management, excluding the rational distribution of forest traffic on the network of forest roads and the management modes on individual logging roads and sections of forest roads. The developed model makes it possible to carry out a theoretical analysis and experimental verification of the interaction between «driver-car-road-environment" system in order to identify the reserves of increasing efficiency of its operation and purposeful management of this process. Transport-operational characteristics of logging roads are the main factors that shape the conditions of timber transport on the road, mode, convenience and safety of traffic and determine the efficiency of road transport, and connections of many characteristics of roads with the traffic modes have deterministic, corrective character. These patterns are the basis for the development of technical requirements for logging roads. The proposed model for integrated creation and management of the functioning of a forest road may already be implemented. However, the design of roads is expedient to provide complex control engineering and organizational measures to ensure the estimated traffic conditions during the whole period of operation of the road, regardless of the time of year and weather and climate conditions. Evaluation of the effectiveness of taken decisions should be made with mandatory consideration for ensuring the required performance of logging road in adverse periods of the year and in difficult weather conditions

Compared with the expressway, most of the traffic flow in urban road network can be denoted as interrupted traffic flow. Based on the current employed equipment for traffic flow collection and traffic signal control in urban roads, different types of traffic flow in urban roads are analyzed with the traffic flow arrival/departure model in transportation engineering. Mathematical models complying with traffic flow changes are utilized to match the traffic flow in both entry and exit road blocks, thus, enabled the automatic detection of traffic incident. This algorithm provides a measurement for the automatic judgment of urban road congestion and the expansion utility of intelligent transportation facilities in urban areas.

Accurate estimation of traffic emissions and analysis of spatio-temporal distribution on urban roads play a crucial role in the development of low-carbon transportation system. Traditionally, a region’s emission characteristics have been studied using numerous emission models with GPS-based spatio-temporal data. Due to the heavy data processing needs of GPS-based data, emission characteristics for a large region have been studied by dividing the region into a limited number of smaller areas or units. Additionally, GPS data are based on a few vehicles in the traffic which does not fully reflect road conditions. This paper proposed an approach that can be used to study and calculate the spatio-temporal emission pattern of a region at a roadway section level by using Baidu’s online traffic data and COPERT model. The proposed method can be used to estimate road-level emission patterns while avoiding the impact of redundant data in large datasets, making the dataset more reliable, applicable, and scalable. The proposed approach has been demonstrated through a study of spatio-temporal emission patterns in the Qiaoxi district within city of Shijiazhuang, China. Online data crawling technology was used to obtain data on urban road traffic speed and driving distance. The linear reference technology was used to construct a two-layer road network model to conduct the coupling and matching of traffic data with the road network data. The COPERT model was implemented to calculate the average traffic emissions on each road in the road network, and a traffic emission intensity index was proposed to quantify the CO, VOC, NOx and CO2 emissions on urban roads in the study area. The analysis results show that the traffic emission intensity of the expressway, trunk road, secondary road, and branch road is high during the morning peak (7 AM-9 AM) and evening peak (5 PM—7 PM). The sections with higher traffic emission intensity are mainly concentrated on the main roads and secondary roads such as Jiefang South Street, Shitong Road and Xinhua Road. Nearly one-third of 2nd Ring and 3rd Ring roads also have relatively high emission intensity. The research results provide new ideas for estimating traffic emissions in urban road networks and analyzing the spatio-temporal distribution of traffic emissions. The research results can also provide a decision-making basis for traffic management departments to formulate energy-saving and emission-reduction measures and promote the development of urban green and low-carbon transportation.

Road traffic accidents claim over a million lives every year in the world. As per World Health Organization (WHO) it is one of the leading cause of death. India, being a rapidly developing country with expanding economy has its own issues as regarding road traffic accidents due to rapid proliferation of motorization. Road traffic accidents causes enormous morbidity and mortality and at the same time, the toll on the economy of the country as a result of it is quite heavy. Road traffic accident is a result of an interaction among different factors which include the environment, vehicle and the human being. Traditionally it is considered that road traffic accidents are accidents which are unpredictable, inevitable and not preventable. But road traffic accidents are indeed predictable and preventable in majority of the cases. This require the knowledge of factors contributing and leading to road traffic accidents. There are certain preventive measures which if adopted can lead to decrease in morbidity and mortality resulting from RTA. Hence, it is the responsibility of all to contribute in reducing road traffic accidents.Keywords: Road traffic accidents; Road traffic injuries; Roads in India, Road safety; Vehicular registration.

ABSTRACT Road traffic accidents (RTAs) result in tremendous loss of lives and prolonged morbidity besides causing sufferings to relatives and friends. Loss of lives and useful working hours inflict heavy damage to a nation's economic activity, loss of breadwinner to family, and deprivation of family bond of love and security. Increasing traffic accidents and subsequent trauma creates heavy burden on our scarce funds and already overburdened hospitals. Road traffic accidents are one of the major causes of death and illness which is preventable. There is tremendous rise in RTAs due to increase in vehicular volume on our roads, incredible speeding of the vehicles, poor driving skills, drunk driving, bad roads, poor traffic control, and lack of public awareness, rampant indiscipline, incompetent authorities and lack of implementation of existing laws to tackle the menace of disrespect to law and rules. The solution to the problem lies in reducing the volume of traffic on roads by instituting efficient public transport system all over, like the one prevalent in advanced nations of the world, honest road engineering, universal education and training of all citizens in driving, creating awareness about road safety precautions, enforcing strict punishments upon offenders indulging in drunk driving and crossing the speed limits, and regulating control of traffic on highways and accident-prone areas.

Full textAbstract:
Suburban roads are an important part of China’s road network and essential infrastructure for rural development. Poorly designed road curves and scarcity of traffic signs have caused an excessively high traffic accident rate in plain topographical areas. In this study, an approach to evaluate and improve rural road traffic safety is introduced. Based on fuzzy and cask theory and weighted analysis, a cask evaluation model is built. It provides a quantitative instant method for analyzing road safety in the absence of traffic accident information or rigorous road space data, by identifying dangerous sections and key impact factors, and ultimately help to put forward traffic safety improvements. Based on the application to a specific section of Xiaodang Central Road in the Fengxian District of Shanghai, the result shows that the pavement conditions of cement-hardened dual-lane rural roads was good, but traffic safety was poor. Missing traffic signs, unreasonable road alignment, and poor roadside conditions were the main problems. Finally, improvements of the short-stave subsystem were proposed: the location of guide signs and roadside conditions should be improved, and the number and efficacy of the rural road traffic signs need to be increased, and markings should be and receive regular maintenance.

Full textAbstract:
In rural areas, land use activities around primary arterial roads influence the road section’s traffic characteristics. Regulations dictate the design of primary arterial roads to accommodate high speeds. Hence, there is a mix of traffic between high-speed vehicles and vulnerable road users (pedestrians, bicycles, and motorcycles) around the land. As a result, researchers have identified several arterial roads in Indonesia as accident-prone areas. Therefore, to improve the road user’s safety on primary arterial roads, it is necessary to develop models of the influence of various factors on road traffic accidents. This research uses binary logistic regression analysis. The independent variables are carelessness, disorderliness, high speed, horizontal alignment, road width, clear zone, road shoulder width, signs, markings, and land use. Meanwhile, the dependent variable is the frequency of accidents, where the frequency of accidents consists of multi-accident vehicles (MAV) and single-accident vehicles (SAV). This study collects data for a traffic accident prediction model based on collision frequency in accident-prone areas. The results, road shoulder width, and road sign factor all have an impact on the frequency of traffic accidents. According to a realistic risk analysis, MAV and SAV have no risk difference. After validation, this model shows a confidence level of 92%. This demonstrates that the model generates estimations that accurately reflect reality and are applicable to a wider population. This research has the potential to assist engineers in improving road safety on primary arterial roads. In addition, the model can help the government measure the impact of implemented policies and engage the public in traffic accident prevention efforts.

The price of ensuring the conditions of continuous, safe and convenient movement of public roads of Ukraine should be based on general patterns of development of society and the country's economy, taking into account the financial and tax policy of the state, the specifics of the road economy, speed, density and intensity of traffic – the main components of road productivity, cost and terms of construction and costs for maintenance and repair. roads, demand for road traffic, other socio-economic indicators, including material losses from road accidents (accidents), as well as the severity of their consequences. The developed methods of assessing the conditions for continuous, safe and convenient traffic on highways establish the priority of planning and implementation of road works aimed at ensuring transport accessibility of different territories of Ukraine, as well as improving safety and improving road convenience 259 through extraordinary, priority and regular improvement of road conditions on those sections of the road network that do not meet the requirements of traffic flows, as well as to provide further development of the road network through the improvement of their transport and operational condition to meet the demand of users for their movement. Improving road conditions both in the most dangerous areas and on highways in general, leads not only to a decrease in the number of accidents and their consequences, but also increases the level of convenience of traffic flows, which is beneficial for the country's economy and society as a whole.

Full textAbstract:
With the rise in vehicle ownership, traffic congestion has emerged as a major barrier to urban progress, making the study and optimization of urban road capacity exceedingly crucial. The research on the medium and long-term free-flowing capacity and queue emission rate of roads takes an in-depth exploration of this issue from a cutting-edge perspective, aiming to find solutions adaptable to the progression of the times. The purpose of this study is to understand and predict the road capacity and queue emission rate more accurately, thus improving the urban traffic condition. Existing literature primarily focuses on short-term forecasts of road capacity, leaving a notable void in the research of medium and long-term road capacity and queue emission rate. This gap often results in a lack of sufficient foresight when urban traffic planning faces practical issues. To fill this void, this study undertook an in-depth examination of the road capacity and queue emission rate over the medium and long term (10 years) based on big data analysis and artificial intelligence theories. This paper employs a Radial Basis Function (RBF) neural network, combined with twelve other parameters that could potentially impact road capacity, such as traffic volume, road width, number of lanes, traffic signal control methods, etc., to analyze the relationship between each parameter and free-flow traffic and queue emission rate. These analyses are grounded in extensive road data, encompassing not only the city’s main roads but also secondary roads and community roads. The study results show a continuous downward trend in the free-flowing capacity of roads and a slight upward trend in the queue emission rate over the past decade. Further analysis reveals the extent of impact each factor has on the free-flow traffic and queue emission rate, providing a scientific basis for future urban traffic planning.

The article aims to identify and consider the basic collisions of administrative legislation on road safety on the territory of the Russian Federation. The theoretical basis includes the normative legal acts of the Russian Federation regulating the designated area of research. The empirical basis is the official statistics of the Main Directorate for Traffic Safety of the Ministry of Internal Affairs of the Russian Federation and the World Health Organization. The analysis of road traffic accidents in the Russian Federation over the past decade (in the period from 2011 to 2021 the total number of deaths in road traffic accidents amounts to 238,663) shows that an acceptable level of safety for road users has not yet been achieved, just like in most of the developed countries, where 1.3 million road users were killed and about 50 million injured as a result of traffic accidents in 2021. Considering the relevance of this problem, the author discloses the targets set by the President and the Government of the Russian Federation in a number of regulatory legal acts aimed at improving road safety; outlines the principles of activities and legal and non-legal means of affecting the participants in these relations to achieve these targets; analyzes and defines the relevant legal categories: “safety”, “safety of participation in road traffic”, “ensuring road safety”. The author assumes that the road traffic safety is possible only in the case of neutralization and elimination of all the negative consequences of road traffic accident, such as death, various injuries of individuals, material losses, etc. Specific conditions that form the road traffic situation and affect its assessment, depending on the correlation of positive and negative segments of its total value, are noted. According to the author, measures to eliminate collisions of administrative legislation on road traffic safety are: legislative consolidation of the concepts “safe driving conditions on roads” and “dangerous driving conditions on roads”, with specification of their content; determination of road traffic safety criteria without limitation to sections of roads equipped with service facilities, which means considering the entire length of the road used.

In many regulatory acts, such as “The Priority Action Plan for Improving the Road Traffic Safety of the Republic of Kazakhstan for 2017–2020”, developed with the support of the Asian Development Bank, and in the “National Concept of Road Traffic Safety” project as well , developed by the Interdepartmental Research Institute called “The Academy of Law Enforcement Agencies” of the General Prosecutor’s Office of the Republic of Kazakhstan, the urgent need to improve road traffic safety is clearly pointed. At the same time, it is necessary to have the information about the extent of the existing problem in the field of road traffic safety, which is ensured by the constant consideration and analysis of the statistical indicators, as well as by planning appropriate measures aimed at correcting the situation and achieving planned indicators in the framework of, for example, the national concept of road traffic safety. Currently, statistics on road traffic accidents, occurring in Kazakhstan, are published by the Committee on Statistics of the Republic of Kazakhstan and the Committee on Legal Statistics and Special Accounting. However in the current situation, this is not enough, especially since the ARC MIID of the Republic of Kazakhstan outlined the program of actions aimed at eliminating the existing shortcomings in the field of the road traffic safety and significant improving its indicators. The analytical investigation of the status of the road traffic safety on the roads of the Republic of Kazakhstan was carried out. This will become a kind of starting point in the consistent work in this direction, which will provide the interested parties, first of all the experts, with the high-quality and reliable information about the main figures, characterizing the state of safety of the road users. Based on objective accident data, it is possible to take the effective measures aimed at improving the situation on the roads of the Republic of Kazakhstan.

We investigated the effectiveness of different approaches at limiting motorized vehicle traffic on unpaved roads designed to support forestry operations (i.e., resource roads). The approaches (i.e., year-round closure, seasonal closure, deactivation, and deactivation and closure) were employed to provide non-road-based opportunities for people to pursue outdoor recreation and nature-based tourism activities by deterring hunters and others from using motorized vehicles to access areas beyond a road closure/deactivation. Using the case of weekend traffic on single-lane resource roads in northern Ontario, Canada during the gun portion of the moose (Alces alces) hunting season, we developed and investigated three general hypotheses. The first hypothesis that closure and/or deactivation approaches significantly reduce traffic on these resource roads was supported. In fact, we estimated that on average these approaches should reduce about 78% of traffic. No support existed for the second hypothesis that the effectiveness of these approaches depends on road quality. The third hypothesis was supported that differences exist in the effectiveness of the four road closure and/or deactivation approaches to reduce traffic on resource roads. A year-round closure was amongst the least while a seasonal road closure was amongst the most effective approach to reduce traffic on these roads.

Full textAbstract:
With continuous economic development, most urban road networks are facing unprecedented traffic congestion. Centralized traffic control is difficult to achieve, and distributed traffic control based on partitioning a road network into subnetworks is a promising way to alleviate traffic pressure on urban roads. In order to study the differences between different partitioning methods chosen for distributed traffic control, we used the normalization algorithm to partition a part of the road network in Changsha City, and we used the results of the Girvan–Newman algorithm and the manual empirical partitioning method as a control group. Meanwhile, an abstract road network was constructed using VISSIM simulation software based on realistic road network parameters. And then, the different partitioning results were applied to the simulated road network to analyze the control effect. The results of the simulation software show that different partitioning methods have different effects on traffic control at subnetwork boundaries and improve traffic pressure to different degrees. Partitioning the road network into four subnetworks provided the greatest degree of traffic improvement. Overall, the proposed distributed traffic control method effectively improved operational efficiency and alleviated the traffic pressure of the road network.

In this paper, we propose a method for deep-learning-based real-time road traffic predictions using long-term evolution (LTE) access data. The proposed system generates a road traffic speed learning model based on road speed data and historical LTE data collected from a plurality of base stations located within a predetermined radius from the road. Real-time LTE data were the input for the generated learning model in order to predict the real-time speed of traffic. Since the system was developed using a time-series-based road traffic speed learning model based on LTE data from the past, it is possible for it to be used for a road where the environment has changed. Moreover, even on roads where the collection of traffic data is invalid, such as a radio shadow area, it is possible to directly enter real-time wireless communications data into the traffic speed learning model to predict the traffic speed on the road in real time, and in turn, raise the accuracy of real-time road traffic predictions.

Jalan Temanggung Tilung is a 2/2 UD type road (two undirected two-way lanes) with a road width of 5.5 meters, which is a connecting road between two major roads, namely the RTA road. Milono and the path of G. Obos. Over time, the volume of traffic through these roads increases every year, plus roadside activities that also increase cause congestion at several points of the way. To overcome this problem, the local government carried out road widening to increase the capacity and level of road services. The study was conducted to determine the amount of traffic volume, performance, service level of the Temanggung Tilung road section at peak traffic hours before and after road widening. Data retrieval is done by the direct survey to the field to obtain primary data in the form of geometric road data, two-way traffic volume data, and side obstacle data. Performance analysis refers to the 1997 Indonesian Road Capacity Manual (MKJI) for urban roads. From the results of data processing, before increasing the road (Type 2/2 UD), the traffic volume that passes through the path is 842 pcs/hour and after road widening (Type 4/2 UD) the traffic volume for two directions is 973 pcs/hour, with route A equaling 528 pcs/hour and direction B equaling 445 pcs/hour. Based on the analysis of road performance before road enhancement, the capacity = 2551 pcs/hour, saturation degree = 0.331, and the service level of the two-way road are level B. Based on the analysis of the performance of the way after increasing the way, the direction capacity A = 2686 pcs/hour and direction B = 2674 pcs /hour, saturation degree for direction A = 0.196 and direction B = 0.166, service level for road direction A and direction B increase to level A

The studyfocuses on the availability and conditions of traffic signs and road markings in some selected roads in the city.Auditing of traffic signs and road markings is carried out as one of the means of promoting road safety andimproving road capacity in the city. The auditing procedure involved field studies through the use of trafficsigns/markings checklists and ranking of road stretches according to the availability and conditions of trafficsigns observed for improvement prioritization in case of financial constraints. In ranking the road sections in accordance to the overall conditions and availability of traffic signs, an index was developed. The index considered six factors of traffic signs availability and conditions that were observed in the field; (i) availability (ii) orrectness of size (iii) visibility of signs (iv) physical condition (v) correct placement and (vi) the need of sign protection. It is recommended that the responsible agency and Municipal councils carry out auditing f traffic signs/markings and identify deficiencies in signage and road markings and plan for improvement accordingly. In case of financial constraints, the developed performance index may be used to rank roads/road sections for improvement priority.

In new-tier cities with rapid urbanization, the reorganization of urban spatial functions and the development of road networks have brought novel challenges to traffic congestion control. Urban land use patterns have a significant correlation with urban traffic congestion. However, whether and how land use patterns of cities close to the roads affect road congestion is less to be discussed. This article investigated the relationship between land use patterns close to the urban trunk road network and traffic congestion in new tier cities Xi’an, China. We adopted the DBSCAN algorithm to cluster POIs and use the mixed POI clusters to label the socio-economic functions of roads. We found the spatial heterogeneity of POIs on the trunk road network and identified the impacts of the scales and types of POI on road congestion based on the empirical analysis. Compared to the POIs as origin and destination of the trips, the POIs as stopover points of the trips cause significantly more road congestion. The POIs with bidirectional flows at entrances/exits are more likely to cause road congestion than the POIs with unidirectional flows. Moreover, the POIs with flexible traffic flows increase road congestion, while the POIs with predicted traffic flows have no statistically significant correlation with road congestion. The results help urban planners to plan the scale, type, and location of POIs close to roads and to optimize the socio-economic functions of roads and alleviate road congestion.

Taking the traffic flow characteristics of Beijing's entire road network as the object, and using the low-frequency traffic big data of GIS (Geographic Information System), the roads of the whole road network are divided into four road grades, and the traffic flow-speed models are constructed respectively. In view of the deviation of the model calculation caused by the sudden rise and fall of the traveling vehicle at night, the flow of the traffic flow model is corrected by cubic polynomial fitting, and the mathematical model is compared, calibrated and verified. Focus on analyzing the influence of roads of different grades and seasons on the characteristics of road traffic flow, and provide data support for further research on intelligent transportation.

The obligation to maintain roads has been regulated in Article 24 of the Road Traffic Traffic Law and criminal sanctions in Article 273 of the Road Traffic Traffic Law. Accidents caused by damaged roads occur quite often, but they are still common in society so that accident victims report their losses to the authorities so it is not uncommon to find cases that have advanced to court. This paper aims to find out how law enforcement is against road administrators who are negligent and what factors are the obstacles. case (case approach), while the data sources used are secondary data sources, data collection techniques through library research, and analyzed by qualitative analysis. Based on the results of the study that the review of criminal law in cases of traffic accidents due to the impact of road damage is based on the description of article 273 of Law Number 22 of 2009 concerning Road Traffic and Transportation, the material crime committed by road administrators is a passive crime that does not pure.

Abstract Introduction. Compared to European countries, the level of road safety in Ukraine is extremely unsatisfactory due to high mortality and road traffic injuries. Improving road safety is one of the important social problems of our time, which is associated with the preservation of human life and health. Problem statement. The problem of road safety in Ukraine is well visible due to the number of dead and injured people on the roads. Road accidents cause huge social losses for citizens and place a heavy burden on the health care system and the economy as a whole. Reducing injuries from road accidents and saving people’s lives is one of the most important tasks for our country. Purpose. In the article the evaluation of safety level on roads of national importance will be conducted (according to certain indicators), which allows to make a conclusion about the compliance of the road network or individual sections of roads with traffic conditions and, accordingly, to decide on planning and prioritization of traffic safety measures. Materials and methods. The study used the method of statistical data processing for the analysis of roads by safety level. Results. The rating of highways according to the level of safety has been established to determine the priority of the road safety inspection in conditions of limited funding. Conclusions. According to the value of the weighted average coefficient of accident rate and severity of consequences of road accidents, it is possible to draw a conclusion about the general level of road safety. This allows to assess the level of safety on the road network as a whole in Ukraine and within a particular region, which helps to develop and implement measures to improve traffic safety on the most dangerous sections of roads. Key words: road, accident, road safety, traffic accidents, dead, road network rating, safety level, injured.

he aim of this paper is to assess vehicular traffic congestion in Yenagoa, Bayelsa State, Nigeria. Traffic congestion is akin to major cities of developed and developing countries, the bane of urban life. The gravity model provided the theoretical foundation for this study, while a survey design involving volumetric count of vehicles and administration of questionnaire to 400 road users along major roads in Yenagoa was also used. The immediate causes of vehicular traffic congestion along major roads and conflict points in Yenagoa are: poor state of the roads, road side trading/market, inadequate public mass transit vehicles, road capacity, and poor traffic signalization. Generally, the effects of vehicular traffic congestion on road users include road traffic crashes and accidents, exposure of commuters and pedestrians to ambient pollutants with attendant health implications, parking problems, effects on aesthetics of buildings and the environment and encouragement of street trading. The result of the regression model revealed that the extracted components explained 0.614 (61.4%) of influence on vehicular traffic congestion in Yenagoa at 0.05 significance level. This study recommends an efficient transport planning system, the pull and push measures of traffic management such as introduction of mass transit and encouragement of off-street parking at affordable price

Full textAbstract:
Short-term traffic prediction under corrupted or missing data for large-scale transportation networks has become an important and challenging topic in recent decades. Since the critical roads have predictive power on their adjacent roads, this paper proposes a novel hybrid short-term traffic state prediction method based on critical road selection optimization. First, the utility function of the quality of service (QoS) for the critical roads in a large-scale road network is proposed based on the coverage and the data score. Then, the critical road selection optimization model in the transportation networks is presented by selecting an appropriate set of critical roads with the maximum proportion of the total calculation resources to maximize the utility value of the QoS. Also, an innovative critical road selection method is introduced, which is considering the topological structure and the mobility of the urban road network. Subsequently, the traffic speed of the critical roads is regarded as the input of the convolutional long short-term memory neural network to predict the future traffic states of the entire network. Experiment results on the Beijing traffic network indicate that the proposed method outperforms prevailing DL approaches in the case of considering critical road sections.
