Circular Bus Network Planning Method in Chessboard-Shaped Road Network

Bus routes planning is the key to the design of public transport system, it determines the status of public transports at a large degree. For the existing bus network traffic problems, such as bus traffic is not balanced in both pace and time, flat-peak conversion is slow, non-linear coefficient is high. Therefore a circular bus network planning method is put out. The overall interests of passenger and bus operators are used as the objective function; the public transportation network technical indicators are used as the constraint conditions. When designing the network, the transfer coefficient and the line length are used for the control conditions. The main through passenger is satisfied at first, and the initial network is laid out by the circular line. Then the bus network is revised according to the constraints conditions with the status of the road network. From the different purposes, different option should be compared by the value of objective function, and the optimal one is gained at last.
