Optimization Study On The Capacity Of Multi-line Bus Station Routes

With the continuous development of China's socio-economic, urban public transport has also been a rapid development, the number of bus lines also increased a lot, especially in big cities, some bus stops at the line number has reached more than 20. As the number of paths of call too much, often at the bus station and the bus line is the phenomenon of long lines, seriously reducing the bus station and the adjacent lane at the traffic capacity, and increased traffic delaysand passengers up and down Off time, the safety of passengers get on and off also had a significant impact. The phenomenon is due to hold the line at the bus station due to lack of capacity.In this thesis, the physical characteristics of the bus station,transport properties running mechanism when public transport go into or out of the analytical site are introduced, and the bus station's research capacity is calculated. In the queuing system model for an overview of the system model using queuing theory to accommodate bus routes to influence features of site analysis of the factors to site capacity, based on established bus routes carrying capacity model of the site, and the theoretical passengers get on and off time calculation, the number of bus-stops berth, the average arrival rate of bus routes to accommodate capacity and site relationships. Carrying capacity of the bus-stops based on the formula line, changing the site from the form of increasing the number of parking sites and change the bus headway, adjust the bus departure time and the change in model para-meters and other aspects of bus routes to accommodate the capacity to site optimization. Finally the Central Hospital of Changsha, Shaoshan South Road, bus stations, for example, calculated with existing data lines to accommodate the maximum capacity of site status, site lines from different aspects to optimize the carrying capacity study and to identify appropriate measures to optimize. Increasing congestion in the city today to address the congestion at the bus station is an important element of reasonable layout site type, location and number of bus lines at the site is extremely important.Papers from the bus station and the starting line with the actual carrying capacity, carrying capacity of the bus station circuit to optimize the bus line as far as possible to resolve the traffic congestion caused by the phenomenon of bus operators and passengers to reduce travel delays, has a very great practical significance and application value.
