Abstract

Intelligent Transport System involves the usage of short-range communication technologies such as the IEEE 802.11, WAVE or the dedicated short range communications standards. Long range communication technologies involve the WiMax, Global system for mobile communication or Global Positioning Systems. The sensor technology such as the Radio frequency identification has also been exploited. This technology ensures better results than the other methods imposed. One such application of intelligent transport system in the public transportation system is the tracking of buses using global positioning system and to inform the commuters about the real time position of the bus. This paper focuses on comparing three different technologies used to help the commuters regarding the positioning of the bus. The comparative study is done between the Advanced Transit Traveler Information Systems, Data warehouses and global positioning system tracking methods. Here, we perform the comparison of the Radio frequency identification technology of determining the bus arrivals being more efficient by message alerts than the other three technologies mentioned above.
