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...

Modelling the saturation flow rate for continuous flow intersections based on field collected data

The continuous flow intersection [CFI) is an unconventional intersection design which has been used in many cities all over the world. However, as an important parameter for the geometric design, signal timing, and operation evaluation, the saturation flow rate at CFI has not been carefully examined. In this paper, a saturation flow rate...

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...
