Development of bus location system using smart phones

Route bus system is the fundamental transportation device for aged people and students, and has an important role in every province. However, passengers decreases year by year, therefore the authors have developed the shortest path searching system called ”Bus-Net” as a web application to sustain the public transport. But traditional Bus-Net can´t inform passage information on a location of a running bus, and does not correspond to the case when the bus is delayed by the road situation. Then, we develop a bus location system that informs a location of a running bus and bus stop passage information. In addition, we develop an algorithm that estimates delay of the bus.
