Modification of Grace′s Density Diffusion Model and its Application

LIU Can?qi, YANG Pei?kun (Tongji University, Shanghai 200092,China)  
Grace′s density diffusion model is dissected, with error having been found.The evolving law of density during the diffusion of traffic platoon at signal?intersection is researched, and right density diffusion model is got. At last, the model is used to infer the expression of the number of vehicles queued before the green time of downstream signal intersection, which are useful in the control of coordinated signals of neighbor intersections.
