Study On BRT And Normal Bus Combined Dispatching

Urban public transport is an important public service closely related to people's livelihood, is Social welfare services. The Priority Development of Public Transport meets China's national conditions and the actual situation of urban transport development is an important tool to improve transport efficiency of resource use and ease urban traffic congestion. For the purpose of improving the utilization of bus rapid transit lanes, public transport system resource utilization and bus service quality, it systematically analyses Bus Rapid Transit and Normal Bus combined dispatching.After summarized the studies of construction and theory on Bus Rapid Transit at home and abroad, it is found that the most prominent point is the low utilization rate of Bus Rapid Transit lane but it takes up too much road resources. The concept of Bus Rapid Transit and Normal Bus combined dispatching is defined, its basic principles and requirements are described, and its process is analyzed.The model for Bus Rapid Transit and Normal Bus combined dispatching is established with the objective ofminimizing the sumof passenger congestioncosts, passenger waiting time cost, bus enterprise operating cost based on the constraints of bus departure times, distribution of vehicles, fleet size, site resources, passengers' value of time, driver wages, vehicle maintenance costs, and other parameters. The process of building the model, the objective function and constraints identified are analyzed in detail.An example is provided to validate the proposed model. The results show that Bus Rapid Transit and Normal Bus combined dispatching is effective and feasible. Finally, the application of this method in practice was studied, mainly in bus lanes planning, the daily scheduling and traffic planning arrangement; further its application and Process in emergency dispatching is studied.
