Study On The Relevence Between Rail And Bus Transit In Mountain Cities

In recent years, with bus priority becoming more important and quick development of railway transportation, it gives the opportunity to improve the traffic problems in China. Because railway transportation has important roles for urban transport, special for the mountain cities, how to coordinate bus and rail transit is a key problem in improving traffic problems in the hill cities. This thesis will have important theoretical and practical significance through doing some researches on the relevance between them.The mountain citi's definition,morphology,internal road network and travel's characters are first given, then three more famous mountain cities: Chongqing, Hong Kong and Tokyo public transport's development pattern, especially the special role of rail transit are introduced.Through analyzing the relations of recycling and feedback between rail and bus transit, causality diagram of social economic and population system, road network system, rail transit system and bus transit system is established. With system dynamics theory's application, population development submodel, network service submodel and public transit contribution rate are used to study the whole systems. and the respectively allocation proportion models are established to determine the development level in urban transportation. Three relevance influence aspects of public traffic network, site and management are researched,then according to every aspect of the subfactors' attributes and the correlation planning methods, suggestion measures of management system and information integration are presented. Finally, a case study with transit line 6 of Chongqing is given.Through these studies, theoretical model of public transit trip contribution, coordinated planning of the bus line and site, and suggestions of management system and information integration are acquired. Some results in this thesis can provide certain theoretical and practical reference for the cordinated development of mountain cities' rail and bus transit.
