AN INTEGRATED GPS/GIS SYSTEM FOR REAL TIME CONGESTION, DELAY AND VEHICLE PERFORMANCE MONITORING

Research at the Transport Systems Centre (TSC) has demonstrated that GPS can allow the capture of not only positional data but also time, speed and GPS reliability variables at a rate of once per second. This data can then be processed in real-time and used as a means of quantifying the amount of congestion and delay being experienced on the road network. This paper presents a case study showing the features of GPS-GIS integration with a series of travel time runs performed along the first author's journey-to-work, in October-November 1994. The paper discusses how GPS-GIS integration will aid in advanced traveller information systems (ATIS) in public transport (using the case study of the 580 bus route in metropolitan Adelaide) as well as wide area congestion monitoring. The paper indicates the levels of accuracy and reliability of GPS, and describes some of the disadvantages for GPS applications in urban areas and investigates the means to overcome them.
