An Efficient Real Time Query System for Public Transportation Service using Zigbee and RFID

In recent decades, the number of vehicles in India has increased enormously, which results in rigorous traffic congestion and pollution in urban areas, especially during peak hours. This paper describes an implementation of Real Time Query System (RTQS) for public transportation service using ZigBee and Radio Frequency Identification (RFID) as a communication medium. The System is a Demand Responsive Transit (DRT) but it is more competent and suitable as it entertains passenger?s demands and gives data such as bus locations, bus number, and number of persons inside the bus in real time. The real time synchronization of this system makes this system more informative and distinctive when compared with other DRTs. Moreover, this system is more flexible and efficient when compared with the conventional systems. This paper discusses the usage of wireless technologies in real time query system and how to make it more reliable using wireless technology ZigBee and RFID.
