Resilient Public Traffic Network Design Considering The Road Grade

With the rapid development of economy and the accelerated process of urbanization, public transportation, as an important part of urban traffic, is developing rapidly. But compared with the speed of economic development and the level of urban development, existing public transport development and urban economic and social development of the contradictions still exist. Therefore, a scientific and reasonable public traffic line network planning has been the important topic which the people to study and explore.Firstly in previous research background, the research status of the existing public transit network planning is summed and a method of resilient public traffic line network design considering road grade is proposed. The influence of the road grade on the line network is put forward. Secondly, a general overview about the influence factors, the principle and the steps of the public traffic network design is made.The detailed analysis and steps of the elastic line network in the entire planning process is made. Thirdly, through improvements on the shortest path algorithm, a distance matrix is translated into the time matrix of the initial line network planning. The second shortest path is calculated for sharing the passenger flow by using the shortest path algorithm. Finally, under the background of Shayang County public transportation planning project, a resilient public traffic network is designed.Through the initial line network planning, an alternate path is provided to make line network can be resilient. By comparison of the status line, initial line and the resilient line, it is proved that the rationality of the planning.By taking the road grade into the traffic network planning, this paper puts forward a feasible scheme for urban public traffic network design, and apply to the actual concrete planning.Also this paper provides a certain foundation for the future research direction.
