- Abstract
In order to reduce the increasing adverse impacts on the life and traffic of residents in the region during the implementation of traffic microcycle, minimizing road connectivity, minimizing travel time of slow traffic, minimizing environmental pollution and minimizing road saturation were taken as optimization objectives. The constraints of arterial road saturation, average speed limit of slow traffic and density of slow road network were considered. A two-layer programming model of multi-objective regional traffic path optimization was established. Genetic algorithm was used to solve the problem, roulette operator and non-uniform mutation operator were used to operate, and the optimal organization of microcirculation road network was obtained. Through the analysis of the example, compared with the road network before the implementation of microcirculation, the road network saturation decreases obviously after the implementation of microcirculation, which reduces the impact on residents and the destruction of ecological environment in the street area, and a reasonable street traffic microcirculation network is obtained.
