Abstract
|
Developing BRT public transport system is one of the best choice in a short period of time effective way to solve the traffic problems in the city and improve urban public transport service levels and operational efficiency . Chongqing 's first BRT line BRT bus priority control system as the main goal of this study , carried out in-depth analysis and research on public transit network and BRT line network model , the model and algorithm design system positioning , develop a BRT bus signal control strategy , and the completion of a GPS - based BRT bus priority control system design . The main contents of this paper : ( 1) to understand the basis of the principle of GPS positioning BRT lines and intersection plane control strategy to optimize the analysis , design a system of two - point positioning model and algorithm ; (2) based on the road , the route , intersection direction of traffic flow , signal control capabilities and characteristics on the basis of research , the development of the BRT vehicles to maximize control strategy ; ( 3 ) through the investigation and analysis of practical problems , for when the BRT conventional public vehicles public intersection interval when , how to ensure that the case does not affect the normal traffic , has a research priority than other public transport vehicles ; (4 ) design of the the BRT bus priority control hardware and software system . Designed based on the analysis of the hardware module function , based on GPS, short-range wireless communications technology , automatic control technology , data communication technology and computer processing technology in one BRT bus priority control device to ensure punctuality BRT vehicles greatly improve the level of the BRT bus service , and promote the development of the BRT . This system has been successfully applied to the first BRT line in Chongqing , made ??good practical effect .
