Optimization Model of the Cross Intersection Signal Timing Based on the Simulation

Abstract

In order to solve signal timing optimization problem of the cross intersection with irregular four phases, this paper presents a new method based on the calculation of lane design capacity. There are five steps of the application in this paper: the collection and simple statistics of basic data; the analysis of present situation; the formulation and solution of signal timing optimization model; the evaluation of optimization results which are based on simulation software VISSIM; an actual example was tested to verify the feasibility of the optimization model.
