The invention discloses a load balancing method for an urban road network. The load balancing method comprises the following steps that S1, statistics is carried out on information of departure places and destinations of all vehicles in given traffic flow, all the vehicles, with the same departure place and the destination, in the given traffic flow are defined as one traffic flow branch, and the shortest path, from the departure place to the destination of the traffic flow branch is calculated; S2, the shortest path is utilized for forming first network topology, weights W of all links of existing second network topology are calculated according to the first network topology, and the shortest path of the traffic flow branch in the step S1 is calculated again according to the weights W in all the links; S3, the steps S1 and S2 are repeated, shortest paths for all the vehicles in the given traffic flow are calculated. According to the method, the traffic flow is distributed, the effect of utilizing city road network resources more effectively is achieved, under the circumstance of ensuring that traffic is not jammed, the handling capacity of the road network is improved, and then the overall performance of the city traffic road network is improved.
