A New Calculation Method of Bus Punctuality Based on AVL Data

An effective solution to traffic jam is to develop public traffic. According to global positioning system (GPS) vehicle positioning system the authors get the bus operation data. Then on the basis of the analysis of the current research, the authors build a more accurate calculation model with extreme value theory, which is used to evaluate the bus running between adjacent sites based on the automatic vehicle location (AVL) data and data mining. The effectiveness of the model is evaluated by a computational example using the AVL data of Shanghai’s No.49 bus. At last, the authors analyze the important role of this index for users and managers, and give some suggestions.
