Modified BUSTRAP: An Optimal BUS Travel Planner for Commuters using Mobile

In this paper, we present an enhanced, efficient and reliable travel planner named Modified BUSTRAP (BUS TRavel Planner). Modified BUSTRAP can be used for planning a bus travel in two well-known metro cities of India. Locations of buses are recorded at a few instances on the roads through sensors. The Planner finds their current and future locations based on these records. We have considered changeover points on a route according to which a route plan would be formed. This helps commuters to break their journey and change/board to another bus to reach their destination. The path from source do destination is found by A* Algorithm, which gives an optimal path. Database Caching has been used to reduce the response time for frequently used queries. The solution employs mobile communication facilities like SMS for proper guidance on the route plan for a given destination and source of the mobile user.
