Dynamic User Optimal Signal Design at an Intersection

In this paper, we investigate the intersection signal design problem from a brand-new point and propose a variational inequality model to describe the intersection signal design problem based on the dynamic user optimal state. The cell transmission model is used to model flow propagation through the intersection and obtain the cumulative flow curves, which is consequently used to formulate vehicles´ travel delay. A sample intersection is used to illustrate the application of the proposed model and solution algorithm, and some results are got by comparison.
