Provided are an adjacent intersection arterial road coordinate control model and an optimization method thereof. The method includes the steps of building an adjacent intersection four-phase arterial road coordinate control model; performing individual coding, initializing data and setting parameters; performing population initialization; calculating values of the fitness of individuals in a population; performing minimum spanning tree clustering on the population; selecting individuals in the population to participate in genetic manipulation; performing genetic manipulation and mutation on the selected individuals; repeating iteration until obtaining the best individual. According to the adjacent intersection arterial road coordinate control model and the optimization method of there adjacent intersection arterial road coordinate control model, the minimum total delay of each vehicle team waiting in line is set as performance indicators, a more complete adjacent intersection arterial road coordinate control model is built by analyzing the signal states that front vehicles and rear vehicles of a vehicle team released in different phases at the upstream intersection encounter before reaching the downstream intersection and whether all vehicles at the intersection are released during release or not, an improved genetic algorithm is used as an optimization algorithm, and the length of the cycle, the arterial road timing, the signal timing and the phase difference are used as parameters for optimization solution.
