Leveraging GPS and SMS-Based Bus Tracking Architecture for an Efficient Transportation

Nowadays, we note a huge population growth in Dakar Region due mainly to the drift from the land. Therefore, the suburbs keep growing and daily workers need to be transported since economic activities and most urban infrastructures are located in Dakar-downtown. The lack of punctuality and the amount of time wasted at a bus stop are big concerns for the national society of transportation “Dakar Dem Dikk” (DDD). We aim to enhance the communication system by allowing the bus passengers to know either how many bus stops it remains for a given bus to reach a fixed bus stop; or the estimated distance between a target bus and its position. The proposed architecture is based on GPS sensors and mobile networks that relay bus position towards bus passengers that request the information. Relying on two heuristics, Landmark-Based and Polygon-Based approach, the obtained results show that \(70\%\) of targets are localized with an error distance less than 100 m.
