The public transport system is growing at a very rapid pace to meet the needs of the overgrowing population, each day thousands of buses are carrying millions of people to their destinations, there is an increased burden on the public transport system. The situations created difficulty in managing and tracking the public transport. Since there are a lot of buses travelling through same route and it creates immense amount of congestion and thereby the buses fail to reach their destinations at promises time, and this has become a major problem especially in cities, where most of the bus users are office going people, who need to keep up with time. With this kind of uncertainty in the transport system, people have to trade off with their time standing and waiting at the bus stop, for their bus to reach. It would be better if user is certain about when the bus is about to reach, investing his time in something productive rather than wasting it standing at the bus stop. In this paper, we use the power of user’s smartphone combined with cloud computing to create a IOT system to provide certainty in the transport system. We use a very efficient and powerful IOT prototyping platform LinkIt ONE board to achieve this, integrate GPS, GPRS and other sensors are makes it stand out from other platforms such as Raspberry Pi and Arduino. We use the GPS and GPRS on the board to get the co-ordinates of the bus, these co-ordinates are sent to a Firebase cloud service and then co-ordinates are fetched in real-time to a React-Native mobile application installed on user’s device. It was observed that, the proposed system brings down the waiting time of the user. This system can be used as a base to solve much more complex problems in transport system, like scheduling the buses and avoiding congestion. © BEIESP.
