Abstract:

A two-lane highway is an undivided highway with only one lane of traffic in each direction. Two-lane highways are one of the most common roadways at mountainous areas in China. Due to the wider range to choose the horizontal and vertical curves in the design of two-lane highways, the combination of both leads to larger differences on two-lane highway capacities. Thus, the highway alignments are one of the key factors which affect the two-lane highway capacities. According to the empirical data and existing studies, it is regarded that there is no impacts on the capacity for horizontal curves w

Abstract:

The performance of two-lane, two-way highways in Iraq, especially in rural areas, is often hindered by high traffic volumes, inadequate infrastructure, and safety concerns. This research focuses on evaluating and improving the performance of the highway connecting Salah al-Din Governorate to Kirkuk Governorate, which faces significant congestion and safety challenges. Using the Highway Capacity Software (HCS 2024) and the Highway Capacity Manual (HCM 7th edition), the study aims to assess the current and short-term future conditions of the highway, particularly in terms of traffic flow and ser

Abstract:

Consistent highway design is expected to provide safe, economical, and smooth traffic operation. Several studies have been performed to investigate the effect of highway consistency on traffic safety. However, the relationship between design consistency and highway capacity and level of service has not been addressed in current research work and design practices. In addition, the effect of the three-dimensional (3D) nature of highway alignments was not considered, and design consistency was studied based solely on two-dimensional (2D) analysis of highway horizontal alignments.

With the nationwide promotion of ETC applications, congestion at highway toll gates has significantly decreased. However, some highway toll gates still experience frequent congestion due to mismatched passage capacity and demand. To address this issue, an innovative approach is proposed to use mobile IP technology in combination with ETC and manual lanes to achieve zero congestion at highway toll gates. Mobile IP technology involves switching IP addresses across different sites to monitor user entry and exit from highways. This reduces congestion at toll gates and significantly saves time for

Abstract:

A microscopic gap acceptance model is presented that simulates overtaking behavior on two-lane highways. The decision to initiate overtaking is expressed as a function of each driver’s perception of the expected time-to-collision (TTC) with the nearest opposing vehicle at the end of maneuver. The available gap is accepted if the driver’s perception of TTC exceeds a predetermined threshold for safe return (critical TTC). The gap acceptance model is calibrated and validated based on overtaking video-recording data for a two-lane highway. The overtaking gap acceptance model is then compared, for

Abstract:

The behavior of a driver of any vehicle is important in estimating heterogeneous traffic conditions with no strict lane discipline. In the present study, a micro-simulation model is used to analyze the mixed traffic condition with different drivers’ behavior parameters. The field data collected on traffic flow characteristics of multilane highways are used in the calibration and validation of the simulation model. Out of the ten coefficient of correlation (CC) parameters in the simulation model, five are used in the present study to make a model of simulation for heterogeneous traffic; the oth

Abstract:

The traffic capacity of the highway toll station strongly affects the traffic capacity of the whole road, and restricts road traffic. In order to avoid the highway traffic jams and decline of traffic efficiency, this article studied highway tollgate queuing discipline, which is one of the main contributing factors, aiming to reduce waiting time and reduce traffic jams. Based on the study of arrival rate of vehicles during peak hours and normal time, waiting time, queue length and the average efficiency of the service for each tollgate, a reasonable and feasible mathematical model is proposed.

Abstract:

The development of weaving area analysis procedures for the next edition of the Highway Capacity Manual, which is to be published in 2000, is described. Weaving has proved to be one of the most complex types of operation to analyze consistently. Although many studies and investigations have examined weaving areas, no single comprehensive research document exists that has resulted in an analysis procedure that has withstood the test of time and application, despite many attempts to do so. As the publication of the Highway Capacity Manual for the Year 2000 (HCM 2000) nears, weaving analysis proc

Abstract:

This paper considers the problem of toll and capacity choice of a new highway with a bottleneck added onto an existing transit network under four ownership/tolling regimes: public fine toll, public flat toll, private fine toll, and private flat toll. Whenever fine toll and flat toll are imposed, in a competitive highway/transit network with constant returns to scale in road construction, an optimally designed and priced privately owned highway would produce positive net benefit justly equal to the total markup with respect to all autocommuters, whereas an optimally designed and priced publicly

Abstract:

A landslide disaster, especially a highway landslide, may greatly impact the transport capacity of nearby roads. Keeping highways open, in particular, is crucial for supporting the functioning of the economy, society and people. Therefore, evaluating the highway landslide susceptibility is particularly important. In this paper, the city of Laibin, in the Guangxi Zhuang Autonomous Region of China, was taken as the study zone. According to data on 641 highway landslide disaster points measured in the field and a basic evaluation of the study area, nine evaluation factors—the elevation, slope, as

The construction of intelligent logistics by intelligent wireless sensing is a modern trend. Hence, this study uses the multistate flow network (MFN) to explore the actual environment of logistics delivery and to consider the different types of transportation routes available for logistics trucks in today’s practical environment, which have been neglected in previous studies. Two road types, namely highways and slow roads, with different speed limits are explored. The speed of the truck is fast on the highway, so the completion time of the single delivery is, of course, fast. However, it is al

Abstract:

A performance assessment tool was developed to assist managers and operators of highway networks containing toll collection facilities. The toll network capacity calculator (TNCC) quantifies a toll facility’s ability to process traffic. The calculator can also help engineers who are designing toll facilities to serve highway systems adequately. TNCC determines the maximum amount of traffic that a collection facility can handle. In addition, TNCC may be used for disruption management during lane closings, incidents, or maintenance checks. Furthermore, TNCC may be employed as a planning tool and

This relationship was utilized to ascertain the field capacity. Subsequently, this data was inputted into VISSIM to generate a simulated speed-flow curve, which was then compared with the actual field curve.
