Microscopic Traffic Modeling Inside Intersections: Interactions Between Drivers

Microscopic traffic flow models enable predictions of traffic operations, which allows traffic engineers to assess the efficiency and safety effects of roadway designs. Modeling vehicle trajectories inside intersections is challenging because there is an infinite number of possible paths in a two-dimensional space, and drivers can...

Robust Signal Control of Exit Lanes for Left-Turn Intersections with the Consideration of Traffic Fluctuation

Traffic throughput at intersections can be improved by using exit lanes for left-turning (EFL), tidal flow lanes near an intersection, which has been recently introduced. This paper considers the operational robustness of the EFL intersection in relation to the control scheme applied to the traffic light setting. For safety and efficiency, it...

Two-dimensional vehicular movement modelling at intersections based on optimal control

Modeling traffic flow at intersections is essential for the design, control, and management of intersections. A challenging feature of microscopic modeling vehicular movement at intersections is that drivers can choose among an infinite number of alternative traveling paths and speeds. This makes it fundamentally different from structured...

An innovative design for left turn bicycles at continuous flow intersections

To improve the practical capacity of the continuous flow intersections (CFI)<br/>and eliminate the conflict between left-turn bicycles and through vehicles,<br/>an optimization design method for left-turn bicycles was proposed.<br/>The pre-stop line for through vehicles and the crossing passage for leftturn<br/>bicycles were set at the pre...
