Study On Optimize Method For Urban Conventional Bus Lines

Theoretical study and urban traffic's construction practice of internal and overseas shows that the fundamental way to resolve the problem of urban traffic congestion is : by giving priority to the development of public transport , to optimize the structure of urban transport and achieve the efficient use of road resources. This article relies on《Technology research of city bus line optimization and rational allocation of resources》which is the science subject of Jiangsu Province , research a practical optimization methods of bus line.By reading reference literatures, this article gives out the optimizing target of the bus line firstly, then analyses the influencing factors for optimization of bus lines and gives out a optimization ideas of bus line for supervising the following specific studies.Aiming at the jumbled status of bus network's functional levels, by combining with city land layout,passengers corridor,road network structure, this article gives out a idea of"on base of the analysis for bus hinges'hiberarchy, by combining with the actulity bus network, bed the busnetwork"for the analysis of bus lines'functional levels, and gives out a corresponding practical method.Diagnoses of bus lines and analysis of optimization way is the base of the bus lines'optimization. Through the point views of macroscopical network and microcosmic lines, this article filtrates the guide lines of reasonable, then use clustering analysis method to analyze the bus network and lines. On base of this, through summarizing the practice experience of specialties layout for bus network, it gives out a idea and practical method of the analysis for bus lines'optimization way.Bus lines'optimization method is the core content of the bus lines'optimization.Through two sides of bus lines'economy benefit and social benefit, on base of the diagnoses of bus lines and the analysis for bus lines'optimization way , by the analysis of bus lines'functional levels , this article gives out a bus lines'adjuestment idea of"adjusting the bus lines delaminately, mainly for bus lines'direction adjusyment, assitantly for bus stations'adjuesment and attemperment adjuetment"and a bus lines'laying idea of"laying delaminately, optimizing for joining the bus network", then gives out the corresponding practical methods.Finally, this article summarizes and lays out the study outcomes and expects the future study direction.
