Signal Phasing-Sequence Optimization of Intersection Based on Traffic Track

Liao Ran-kun

Open publisher page 1 citations

Abstract

Among Intersection signal control in urban areas,the Phasing-Sequence design has a very close relationship with the traffic flow path through the intersection.Without changing the phase combination of circumstances,a reasonable Phasing-Sequence can greatly enhance the efficiency of intersections.By analyzing the conflict point of traffic tracks in intersection and ensuring the safe passage of vehicles to pursuit the maximum of green signal ratio,this paper establishes a Phasing-Sequence optimization model.Taking the intersection of Guangzhou as an example,the Phasing-Sequence optimization resulted in an upgrade of efficiency of 13.4%.
