Discussion on the Future Building of Urban Rail Traffic Network of Hohhot

Based on the detailed analysis of the characteristics of urban rail traffic planning，and with analyzing city current situation of Hohhot，the necessity and sufficiency of the future network of urban rail transit in Hohhot are firstly analyzed .Then，according to the economic and social development goals of Hohhot，city scale and the present traffic situation as well as the city traffic construction planning and urban population forward distribution, the future sort of the project construction here is discussed. Finally,from the perspective of view of the economical society, some suggestions are put forward on integrated planning of urban rail transit network—— railway in order to enrich the theories and the methodology of the urban mass transit network planning.

Emergency is one of the main factors affecting the operation security and reliability of urban mass transit system. In order to improve the ability to copy with sudden accident, the Emergency Passenger Flow Guidance System was adopted, which can realize the effective guide of passenger flow under the emergency. On the basic of the study of passenger guidance technology and the design of the passenger guidance system, this paper takes Beijing urban rail transit network as an example to simulate the process of emergency passenger flow guidance. The result shows that the passenger guidance can ensure the security and open of the urban rail transit network to some extent through effecting passengers' travel plans.

Urban Rail Transit Network

Hyperpaths enumeration is one of the basic procedures in many traffic planning issues. As a result of its distinctive structure, hyperpaths in Urban Rail Transit Network (URTN) are different from those in road network. Typically, one may never visit a station more than once and would never transfer from one line to another that has been visited in a loopless URTN, meaning that stations a hyperpath traversed cannot be repeated, neither do lines in loopless networks. This paper studies the relationships between feasible path and the shortest path in terms of travel costs. In this paper, a new definition of hyperpath in URTN is proposed and a new algorithm based on the breadth first searching (BFS) method is presented to enumerate the hyperpaths. The algorithm can safely avoid hyperpath omission and can even be applied in networks containing loops as well. The influence of parameters on hyperpaths is studied by experimentally finding hyperpaths in the subway network in Beijing. A group of suggested parameter pairs are then given. Finally, a numerical experiment is used to illustrate the validity of the proposed algorithm. The results imply the significance of the convergence of the BFS algorithm which can be used to search hyperpaths in large scale URTN even with loop.
