In view of the increasing demand for urban distribution in traffic congestion environment, the calculation method of vehicle speed and travel time across time periods in time-varying network from the change law of urban traffic flow is put forward. Considering the influence of distance, time, speed, load and fuel factors on the cost, a mathematical model with the sum of fuel consumption cost, carbon emissions cost and fixed vehicle cost as the optimization objective is set up and the genetic algorithm is applied to solve the model. The comparison of the path optimization arrangements from the traditional TDVRP model with the total mileage minimization and carbon emissions minimization verify the effectiveness and feasibility of the model and algorithm in this paper.
