Travel Time Model of Left-Turning Vehicles at Signalized Intersection

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...

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...

Observing space - time queueing dynamics at a signalized intersection using connected 1 vehicles as mobile sensors

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...

Developing an Analytical Model and Simulation of The Contraflow Left-Turn Lane at Signalized Intersections

At some intersections, excessive queue lengths may spill out of the left-turn bay and block the through lanes, jeopardizing level of service for the entire intersection. One of the most effective plans recently presented by the researchers is the "Contraflow left-turn lane" (CLL) In this method, left-turn vehicles will use the nearest lane in the opposite direction in addition to the usual left...
