Predicting Optimal Trajectory of Left-Turning Vehicle at Signalized Intersection

Delay at Signalized Intersection

An intersection is a shared space that is used by more than one approach at a time. A signalized intersection is one where the shared space is used alternatively by a fixed number of approaches for a pre defined time interval as per the phasing scheme used for the intersection. Delay and queuing process are the main characteristics of such an intersection which help in analyzing and designing t...

Characterizing Signalized Intersection Performance Using Maximum Vehicle Delay

Average delay is perhaps the most commonly used measure for characterizing the performance of signalized intersections. Current methodologies for estimating the average delay rely on the use of models based on volumes and green times. In practice, it is challenging to develop such real-time measurements of delay, due to the difficulty of accurately measuring vehicle arrivals and departures. How...

Pedestrian Accidents with Left-turning Traffic at Signalized Intersections: Characteristics, Human Factors and Unconsidered Issues

Gap Acceptance Models for Left-turning Vehicles Facing Pedestrians at Signalized Crosswalks

Pedestrian-vehicle conflicts are considered as one of the most common safety problems at signalized intersections. The threat to pedestrian safety is mainly related to the interaction with turning vehicles, especially left-turners (left-hand traffic). This paper aims at analyzing the lag/gap acceptance behavior of left-turning vehicles considering pedestrian movement at signalized crosswalks. F...

A Model of the Urban Road Intersection Left- Turning Restriction

Intersection left-turning restriction is one of the important ways to solving the road congestion of the builtup area; however, how to set scientifically and rationally is the key. A bi-level programming model was making under the minimum the premise entire traffic network access time by using the stochastic traffic assignment model which is more appropriate. The upper planning described the in...
