Optimization Control And Designing In Intersection On Bus Rapid Transit

With the development of urban economy, because the traffic of urban increases in the gross and the traffic problems of urban become increasingly severe, the traffic have become the bottle neck restricting urban economy. Because of less of the average dynamic occupying road area and little pollution, urban public transport is the main approach accounting for the transport problems. Limited by the disadvantages of high invest, long build period and less flexible, railway transit isn't advocated. Owing to a economic and efficient public transit, Bus Rapid Transit (BRT) is a better way to solve the urban traffic problems.Compared the method of BRT lane, the paper mainly study the bus lane intercalated in the center of road. It analyses the setting principle in the aspects of the condition of road and traffic, works out the total travel time and optimal vehicle scale being saved after the bus lane sitting in the center of road for all traffic participators total travel time is shortest.The paper analyses the necessity of BRT signal priority in the intersection, and enumerates the main control mode. It discusses control tactic on the side of signal priority in the plane intersection, the paper considers how to make the BRT vehicle carry out line control in the intersections.From the point of view of the shortest travel time, the paper discusses two aspects if the intersection signal cycle is aptotic.The case analyzed, method is maneuverability to control and design optimally in a intersection on bus rapid transit.Factors of liner control, impact of BRT stops and corrected modulus on passby and non- mobile can be studied in the ulterior research.The research will provide the references to control and design optimally in a intersection on bus rapid transit for in our country's cities.
