Space-Time Resource Integrated Optimization Method for Time-of-Day Division at Intersection Based on Multidimensional Traffic Flows

Based on the change trends of traffic flow in different controlled directions at an intersection, space-time resource integrated optimization method for TOD (time-of-day) division based multidimensional traffic-flow data is proposed this paper. By analyzing 8, 4, 2, and 1 dimensions commonly used dynamic Fisher algorithm to complete time segment sequence dimensions. On basis, preliminary completed, phase timing lane-use assignment corresponding periods are optimized. Then, adjacent merged tested final result division. In order verify effectiveness method, schemes carried out by using actual intersection Wuhu City, total average vehicle delays throughout day evaluated VISSIM. The results show that more adopted, refined scheme is, less delay intersections are. particular, after further optimizing can reduce day. It shows carry division, assignment, has good applicability.
