Abstract: An improved pedestrian delay model was proposed for signalized intersections with a two-stage crossing in this paper. This delay model considers the pedestrian physical queuing length when they are waiting on the curbside ...

Abstract: This paper addresses the global optimal signal plan of a fixed time control for an isolated signalized intersection with central pedestrian refuges considering both vehicle delays and pedestrian delays. A signal phase plan, ...

Abstract: Operators of personal transport units (PTUs) face the challenge of intelligently balancing the locational demand and supply of PTUs in order to mitigate surpluses or deficits at PTU pickup stations. To accomplish this goal, ...
