In this paper, based on traffic flow characteristics of urban highways and discreteness 才 theory of numerical analysis, a series of traffic models including traffic generation model, car-following model, and lane changing models were built to study microscopic traffic flow simulation and calculation methods of urban road signal controlled intersections. Then a numerical simulation C++ program was coded on Linux platform using discrete mesh method after determining a reasonable traffic flow simulation parameters, and simulation results were verified using traffic survey data analysis. Finally, the basis for how to optimize urban road intersections congestion state and how to make decisions about traffic management and control of signalized intersections were provided, and the optimized way to solve traffic delay was hereby recommended.
