As one of the most important urban commuter transportation modes, urban rail transit (URT) has been acting as a key solution for supporting mobility needs in high-density urban areas. However, in recent years, high frequency of unexpected events has caused serious service disruptions in URT system, greatly harming passenger safety and resulting in severe traffic delays. Therefore, there is an urgent need to study emergency evacuation problem in URT. In this paper, a method of bus dynamic coscheduling is proposed and two models are built based on different evacuation destinations including URT stations and surrounding bus parking spots. A dynamic coscheduling scheme for buses can be obtained by the models. In the model solution process, a new concept—the equivalent parking spot—is proposed to transform the nonlinear model into an integer linear programming (ILP) problem. A case study is conducted to verify the feasibility of models. Also, sensitivity analysis of two vital factors is carried out to analyze their effects on the total evacuation time. The results reveal that the designed capacity of buses has a negative influence on the total evacuation time, while an increase in the number of passengers has a positive effect. Finally, some significant optimizing strategies are proposed.

This article analyzes the current development status of rail transit in various cities in China. Most cities are still dominated by subways. Then the relevant data is processed to obtain the linear relationship between transfer stations and rail mileage, rail stations and summarize the domestic rail Establish quantitative standards and conclude that rail transit has not yet become a transportation network. Then use the five indicators of line mileage, number of stations, number of interchange stations, average daily passenger volume, and passenger transport intensity to cluster the domestic urban rail transit using the method of cluster analysis, combining spatial Euclidean distance and compactness and other indicators Analysis, the classification results obtained have certain reference value.

This paper researches the influence of urban rail transit based transportation structure on development of dispersed multi-center city. After the studies of the features of urban rail transit and characteristics of city forms, we constructed the snowflake-shaped transportation structure model of dispersed multi-center city, which took urban rail transit as the backbone of transport network. Finally we analyzed the feedback effect from urban rail based transportation to the development of urban form.
