The generation model of urban rail transit planning line network and its application in route design

At present, the research on urban rail transit planning line network is not in-depth, which leads to the decline of the utilization rate of line network. Therefore, this paper studies the generation model of urban rail transit planning line network and its application in route design. The basic network of urban rail transit planning line network is analyzed. The travel demand, urban population size and residents' travel intensity are taken as the limiting conditions. The interrelation between the line network and the city size is analyzed by using the service coverage area method of line network. The application results show that the model can attract more than 1400 passengers per unit length in peak hour, and the average generalized travel cost of passengers is about 12 min. The model has a high matching degree between the structure of the line network and the intensity of urban travel demand, and the utilization rate of the line network is high, the practical application effect is good.
