The invention discloses an intersection signal optimizing control method in a heterogeneous traffic state. The method comprises the following steps that an intersection with heterogeneous traffic flow convergence serves as a research object, a video detector is installed on the intersection, and heterogeneous traffic characteristics of all entrance lanes are identified; a vehicle driving simulation model is established according to the heterogeneous traffic characteristics of all the entrance lanes, heterogeneous traffic flows are simulated, and saturation flows of all the entrance lanes are obtained; signal parameters are optimized on the basis of an all-phase equisaturation principle, and a signal timing plan of the intersection is obtained. By means of the intersection signal optimizing control method in the heterogeneous traffic state, maximum utilization of traffic capacity of the intersection can be achieved, delay of the heterogeneous traffic flows for passing through the intersection is greatly reduced, and the operating efficiency of the signal intersection is improved.
