Abstract


With China 's rapid economic development , urban transport has become tighter , to some extent affected the city's economic development and people's living standards improve . One important way to ease the traffic congestion a priority the development of public transport system. Priority to the development of public transport is an important content is to optimize public transportation network , improve the public system service levels, enhance the competitiveness of public transport . So how to combine the needs of urban development construction and optimization of existing public transportation network , enhance attractiveness of public transport , has become necessary to study the issue. Transportation system is affected by many random factors effects, such as weather conditions , traffic accidents , etc. Therefore, in the planning and management of the public transportation system , only take into account the constant indicator is not enough, as the probabilistic reliability index to better reflect its dynamic random , allowing for transit operating conditions for a more accurate and more comprehensive evaluation of non- employed than ever before, the probability targets more applicable . This transport system at home and abroad on the basis of the reliability of research results , drawing on the road network reliability optimization theory, the public transportation network reliability optimization methods for initial exploration , this paper proposes a general idea of ??public transportation network reliability optimization and procedures ; describes the importance public transportation network in the line , the line unit meaning the degree of importance , and the importance line formulas are derived ; established a reliability analysis based on run- time urban public transportation network optimization model ; finally describes the use of positive post enumeration method for solving the optimization model approach for optimizing bus network , improve public transportation network service level has important practical significance.
