Study On Layout Planning For Bus Stations And Parks Of Urban Public Traffic

With the rapid development of social economy and urban construction, as well as the rapid increase of vehicle ownership, the transportation characteristics and the spatial distribution have also changed. Along with the social economic development, the growth rate of urban motor vehicles is greater than the speed of urban road construction, there has been a phenomenon of traffic congestion. In order to adapt to economic and social development and urban construction, improve the image of the city and the urban grade, reduce the pressure on urban traffic, vigorously develop the public transportation, implements the strategy of "bus priority", it`s very important to meet the needs of the public transport. And the bus station plays an important role on supporting public transportation operation and residents. It is necessary to carry out the scientific and reasonable planning.On the basis of the present research status at home and abroad, this paper elaborates the basic theory of bus station, and analyzes the bus station planning supporting the implementation of the security model, and then to the bus station design and the process of combing; on macro urban population forecast based on of future years bus trips for calculation, and combining with the public traffic line network planning in the future of transportation scale. Finally, calculate public transport capacity to scale estimate the size of the various types of bus station.Respectively on continuous bus selection model and discrete bus location model are studied respectively, by constructing the objective function of bus station layout, reasonable optimization, and the suitable conditions of two models respectively as well as the advantages and disadvantages were described in detail; Traditional regular bus depot location models only consider the physical distance factor, not consider other cost. Therefore, in the process of bus location selection, we consider the generalized distance cost of time and space costs. Furthermore, we embed the generalized cost model into bus terminal optimization method, and based on the expression of the various costs, build the layout optimization model of bus terminal with minimum cost, which can get the reasonable planning of bus locations; Finally, taking Songyuan city as an example, on the basis of investigating the present situation of mining data, analyzed those data of Songyuan city, thus it is concluded that the actual problems existing of bus station layout in Songyuan city, at the same time with the overall urban planning and related data to forecast bus transit demand and by supporting the planning of the transit network of form to predict the scale of transport capacity, finally optimize the future years of bus terminal layout, combined with the actual situation continuously optimized layout scheme and eventually get the bus terminal planning scheme. Verified by integrating theory with practice in this paper, study the feasibility of the method, but also constantly find and solve problems in practice, in the process of theory to guide practice and continuously enrich the theoretical knowledge and practical experience.
