An New Offset Model for Arterial Road Coordinate Control and Its Optimization Method

By phase optimization design on arterial road coordinate control system, an new offset model for arterial road coordinate control is established in this paper. The model considers all the factors such as road average speed, fleet dispersion, turning traffic flow from crossway and asymmetry of vehicles arrival distribution which greatly influence the control effect of arterial road coordinate control scheme. In this paper, total delay and total number of stops are taken as the offset model output, and the rules of two directional traffic flow delay at the intersections are particularly analyzed. Moreover, programming calculation of MATLAB is introduced to realize the optimization of the offset model. A new approach that optimizes the offsets of arterial road coordinate control system is put forward.
