Modeling of Gap Acceptance Characteristics of Right-Turning Vehicles at Signalized Intersections

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...

Effect of Gap Acceptance Behavior of the Right Turning Vehicles on the Major Road Stream for Uncontrolled Three-Legged Intersections under Mixed Traffic Conditions

Uncontrolled intersections are the intersections where there are no external signs or signals to control the movement of vehicles. In mixed traffic conditions priority rules are often violated by the road users. In All-way-stop-controlled intersections (AWSC), the vehicle should stop themselves before they enter the intersection and should check whether any vehicles are present in the other app...

Micro-simulation of vehicle conflicts involving right-turn vehicles at signalized intersections based on cellular automata.

At intersection, vehicles coming from different directions conflict with each other. Improper geometric design and signal settings at signalized intersection will increase occurrence of conflicts between road users and results in a reduction of the safety level. This study established a cellular automata (CA) model to simulate vehicular interactions involving right-turn vehicles (as similar to ...

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

I Guidelines for Right - TurnTreatments at Signalized Intersections

arterial corridor greatly impacted by strip commercial development. The data-gathering efforts consisted of extensive traffic counts and travel-time and delay studies. This enabled us to see firsthand the great congestion that was occurring on the street. At the four most-congested intersections, unequal queuing between the two through traffic lanes was observed. In all cases, the right lane’s ...
