In today’s world, due to rapid increase in population, there is a need for efficient public transportation system, as the increased population increases the burden on public transportation like bus, etc. (Manini Kumbhar et al., 2015). The main objective of this paper is to carry out a research on city bus tracking in Demand Responsive Transit (DRT) using RS485 LAN, in order to make it much more efficient, reliable and less expensive. This research is not the only way to develop this kind of system and by no means suggested as the best solution, but it can definitely be one of the best alternatives we have today and can be used in many areas where there are no 3G, WiFi or other long-range wireless technologies available. This study will also help to understand the potential of city bus enquiry and make the bus commuter’s life easy. Till now, RS485 is being used as in-house or in-vehicle technology, but this study brings in the idea of using RS485 as communication tool for Inter-Vehicle and Vehicle to Infrastructure.

In today’s world, all the cities are overpopulated. The tracking of buses while moving on highway is a very critical task. A person who is waiting for the bus may want to enquire about the position of current location of bus, but phone discussion is not always possible due to traffic disturbances (Sujatha et al., 2014). By understanding the future scope of technologies available today, we will have various types of applications and improvement of bus stand monitoring and control. The most efficient way for people to transport is public transport such as city busses, etc. The main advantage of city bus commuting is that it reduces the overall pollution, reduces the traffic on road, and also the problem of parking is solved to a certain extent.
