This paper introduces a new bus mapping system, especially for mobile usage. Web architecture is purposely used so as not to limit the system into a particular organization. Once a local map is given, an automated map will be ready to use in the mobile device to interact with Global Positioning System (GPS) and mapping service API (Bing Map) features. The paper describes the instrument and component of the key design of the system. The feasibility of the architecture has been evaluated with Window Phone 7 (HTC HD7) within the campus. A wellknown optimal shortest path algorithm, Dijkstra, is used to find the local route. In addition, especially for a large number of nodes or bus-stops, a heuristic method based on Dijkstra is proposed when a particular route needs to be recalculated, and the performance evaluation results comparatively show the substantial reduction of computational time with a slight increase of path cost. |
