Bus Network Optimization Of Yanzhou City

Urban public transportation is the harbinger of social production, the key of a city function to operate and an important window of the material civilization and spiritual civilization of a city. Therefore the development of urban public transport has become the consensus of countries in the world. Currently, there has been the opposite maturity public transportation network planning in the big cities and the medium-sized cities in our country. But compared with those cities, the whole developments level of public transportation are still at the start stage in most small cities and city towns. This is the county-level city in Shandong Province --- Yanzhou concrete examples of small and medium sized city bus line network optimization problemsYanzhou City, which is located in southwest of Jining City. It has superior geographic advantages, is one of the eight largest railway hub in Shandong's largest rail freight marshalling yard inside, is the southwest's largest cargo distribution center and passenger transit. It is a potential but young and vibrant new city. In this paper, absorbing foreign advanced on the public transport network optimization theory and methods based on the transportation system on the status of Yanzhou field research on the existing bus passenger OD surveys conducted by the evaluation of specific indicators of the status of the Yanzhou make the assessment, identify deficiencies and defects in planning. Combined with the city's public transportation network of existing situation and future development plans of the specific situation, set up urban development can be adapted to small and medium bus line network optimization model, and using the model implemented on the existing bus route optimization.Given the scale of development Yanzhou city, special transportation environment as well as the scale of the existing public transport, this comprehensive consideration of various optimization programs in the premise, put forward a total trip time for bus passengers, the minimum and maximum effectiveness of public transport enterprises to optimize the target, 13 existing bus routes were optimized. In the optimization, the center of the city and suburbs into two parts, the center will focus on optimizing the total transit passenger travel time minimum and maximum effectiveness of the two bus companies goals; in the suburbs, you need to consider the economic co-ordination and social benefits, in line between urban and rural, suburban residents to facilitate travel, the idea of building a harmonious society, strive to improve the public transportation network coverage in rural areas, to speed up the process of urbanization, Yanzhou made to achieve the goal transit villages. For the choice of bus lines, then use the line reservations, line cancellation, line extension, line truncation, diversion routes and line combined adjustment method.Yanzhou bus lines on after optimization of the original lines were compared after adjustment of bus line network operators more rational, more scientific planning, increase awareness of road use efficiency. Conducive to safe and convenient urban and rural residents to travel, to promote rapid economic development in urban and rural areas. Similar to the same level while the city's public transport planning as a reference.
