In order to alleviate the pressure of the transportation system,the optimal scheduling method of traffic flow balance of smart city road network under node cell division is designed.Obtain the flow separation function between different traffic routes,define the path traffic flow and available section cost,obtain the probability function of travelers on a certain section of the path,and calculate the traffic flow of each section of the smart city road network.Obtain the flow conservation and vehicle transfer function,calculate the separate sequence of variable cells,and establish the cell division model of traffic nodes.The optimal scheduling algorithm of traffic flow balance is designed to obtain the optimal scheduling results of urban road network balance.Set the simulation parameters and compare the path flow of the three road network models before and after optimization.The simulation results show that the path flow in the road sections in the morning peak and evening peak hours is significantly reduced,and in other periods,the optimized path flow also decreases to varying degrees,and the more complex the road network model is,the better the scheduling effect of this optimization method is.
