My City Fast Public Transport System Analysis And Design

Public transit system was the most important constituent of urban transit system in China. As the rising public transit model, the Bus Rapid Transit (BRT) was the key to the sustain development of urban transit to our country. Rapid public transit system was a complex system, based on the achievement of BRT in China and abroad, the paper began with the situation of society and economy in Mianyang city as well as the trend of urban transit, and pointing out the pressing for Mianyang to developing BRT, for the city urban transit and public transit operating status, the paper analized four systems which included the public transit system, the demand and forecast of the passenger system, the planning and design system and the construction planning and projiect management system with the methods which were system analysis, projiect management, transport planning, and provided effective support for the implementation of the public transit construction.Firstly, based on the current situation of urban transit and public transit in Mianyang, the survey date of public transit was analyzed. And the classic Travel-Demand Model was selected to forecasting the passenger flow volume, and proved the necessity of BRT for Mianyang city.Secondly, on the result of passenger flow volume forecasting, the planning and design was discussed for Mianyang BRT in 4 aspects, such as public transit networks, bus terminal, bus capacity, operational and signal priority system. Moreover, some strategy were brought forward and discussed, such as BRT networks with 2 east-to-west routes and 1 north-to-south route, bus only lane by sides, constructing bus terminal in Transit-Oriented Development model, 18 meters bus, bus priority signal system, intelligent operation system, passenger information service and so on.Finally, based on the public transit technical equipment of Mianyang, and unified the native national economy and the social development, bringing forward the steps of Mianyang BRT. Carrying on the BRT planning, the strategy for BRT project management was formulated.The research obtained the rapid public transit system of BRT in Mianyang city, which enriched the connotation of Mianyang public transit system, and summarized and promoted the research in past. The research provided some basis for constructing BRT system, so as to match the requirement of decision makers, offering some theoretical and practical reference for the later BRT research and the sustain development of Mianyang urban transit. Meanwhile, this system was based on current social circumstance and would change with the variety of the social, just a starting point of a huge public transit system.
