Design and implementation of passenger guidance system based on accessibility analysis of the last train

With the expansion of urban rail transport (URT) network, the average transfer number has increased. At the same time, not all the coordination among connecting routes can be implemented. Passengers can query the last train time of the stations, but they aren´t sure if they can reach their destinations. Given the demand, a passenger guidance system based on the accessibility analysis of last train is designed. At first, the paper analyzes demand on the accessibility of last train under the condition of network. Secondly, function modules of this system are designed in the paper, including modules for accessibility judgment and information distribution. Then, this paper suggests the function structure which represents logical relation of several functions and information transfer among them. Finally, implementation methods for these functions are proposed.
