Abstract:

In order to optimize customized bus routes in real time, a route optimization method based on reliability shortest path is proposed. The aim is to efficiently and quickly deliver passengers to their destinations in complex traffic environments. Firstly, we describe the reliability shortest path and establish the reliability spacetime network. Then, the algorithm steps for solving the shortest path of reliability are given. Next, we construct the objective function with the minimum total cost of passengers and customized shuttle bus operators which solved by Tabu search algorithm. Finally, we take a city customized shuttle bus network as an example to verify the model. The results show that compared with the shortest path scheme, the proposed method is similar to the actual operation. It can greatly improve the reliability of bus under the condition of rush-hour traffic jams and enhance the level of bus service.

Key words: integrated transportation, customized shuttle bus, reliability shortest path, space-time network, Tabu search algorithm
