The Main Commercial City Of Harbin Public Transportation Route Optimization And Simulation Research

With the development of economy and technology, the size of cities is doubly growing, the urbanization process is accelerating, and social and cultural activities show the unprecedented prosperity of the state, so the status of public transport in social development is gradually increasing, and the travel demands of the residents is also growing. Many cities which are facing traffic congestion, road congestion, frequent accidents and other traffic problems, these problems seriously affect the normal life of city residents and restrict the sustainable development of cities. The main reasons are excessive growth of private cars, the low level of public traffic services, less competitive, irrational construction of urban transportation structure, as well as that the road traffic infrastructure can not meet the rapid growth of traffic demands.In response to the above problems, this paper mainly expounds the general principles, goals, constraints, and optimization of bus lines as well as its commonly used methods. According to the survey of bus passengers in Harbin, combined with the foreign bus service level standards and Chinese actual situation, the paper try to determine the evaluation of the public traffic service levels for bus operating conditions in China, and put forward urban public transport service level evaluation grade. Targeted to the Daoli main business district in Harbin bus lines, and established simulation platform TransModeler, we conducted a survey of bus operating conditions and road traffic conditions data, simulation and analysis on the the Daoli main business district typical bus lines operating conditions, and proposed to optimize the program. The simulation run well.Finally, on the basis of analyzing the operating conditions of the Daoli main business district in Harbin, the paper has put forward some proposal of public transport development in the main business district of Harbin.
