Signal Timing and Detector Databased Reconstruction of Vehicle Trajectories on Urban Arterials

Abstract:

Based on the shockwave theory and traffic simulation concept, this paper presents a new reconstruction method of vehicle trajectories on urban arterials with detector data and signal timing data. Unlike the existing methods, the proposed method takes into consideration the impacts of lane change and roadside entrance and exit on vehicle maneuvers without relying on highfrequency floating car data. The proposed method has been validated at a signalized arterial in Qingdao City of China.
