GPS-GIS APPLICATION IN REAL-TIME TRAFFIC CONTROL, CONGESTION MANAGEMENT AND FLEET MANAGEMENT

This paper examines the use of GPS in real-time vehicle tracking, congestion monitoring and vehicle performance monitoring, for both private vehicles and public transport. It addresses these issues from a practical point of view and provides some results on accuracy and reliability issues for GPS in urban traffic situations. The paper indicates how GPS data can be used to derive a number of parametric measures of congestion and in automatic vehicle identification and location. The paper demonstrates the value of integration of GPS with Geographical Information Systems (GIS) software, especially for fleet management and traffic systems control.
