Left-turn crashes occur frequently at signalized intersections and often lead to severe injuries. This problem can be addressed through the implementation of protected left-turn signals. This gives left-turning vehicles the right to enter the intersection free from conflict with opposing drivers and pedestrians. The present study analyses the effect of this measure on crash occurrence. The stud...

203 words) In ITS (Intelligent Transportation System) equipped urban transportation systems noncritical junctions are often ignored in short-term traffic condition prediction algorithms as the traffic data collection systems in these junctions are not adequate. The paper proposes a shortterm traffic volume model based on a combination of discrete wavelet transform (DWT) and Bayesian hierarchica...

The acceleration and deceleration rates vary from one vehicle type to another. same also exhibits variations in due vast variation their dynamic physical characteristics, ratio between weight power, driver behaviour during manoeuvres. Accurate estimation of is very important for proper signal design ensure minimum control delay vehicles, which are passing through the intersection. present study...

How to estimate queue length in real-time at signalized intersection is a long-standing problem. The problem gets even more difficult when signal links are congested. The traditional input–output approach for queue length estimation can only handle queues that are shorter than the distance between vehicle detector and intersection stop line, because cumulative vehicle count for arrival traffic ...

unlike the typical stage-based policy commonly applied in Japan, the group-based control (often called movement-based in the traffic control industry in Japan) refers to such a control pattern that the controller is capable of separately allocating time to each signal group instead of stage based on traffic demand. in order to investigate its applicability at signalized intersections in Japan, ...

The problem with traffic congestion is particularly expressed in urban areas where possibilities for physical increment of capacity are limited or impossible. Significant in the approach to solving this problem is the usage of Public Transport (PT) and the implementation of various advanced control measures that can improve the quality of overall public transport system. The main objective of t...

Abu Dhabi’s government has taken several initiatives to improve the safety of city’s highways, such as reducing traffic accident occurrence, red light violations, and property damage associated with accidents. However, intersections are still many severe accidents, violations. To help authorities pinpoint major contributors deterioration performance signalized junctions, this study employed a n...
