Abstract

The backbone of any successful Integrated Traffic Management System (ITMS) for a metropolis is the availability of reliable, accurate and real-time data. Travel time, speed and delay are three of the most important factors used in ITMS for onitoring, quantifying and controlling congestion. A global positioning system has recently become available for civil applications and, as it provides real-time spatial and time measurements, it has an increasing use in conducting different transportation studies. This paper presents the application of GPS in collecting travel time, speed and delay information on 64 major roads all over the State of Delaware. A comparative statistical analysis was performed between data collected by the GPS method and data collected simultaneously by the conventional method. The GPS data proved to be at least as accurate as the data collected by the conventional method and was 50% more efficient in terms of manpower. Moreover, the sample-size requirement was determined to maintain a 95%confidence level throughout the controlled test. Benefiting from the Geographic Information System's Dynamic Segmentation tool, our travel time, delay and speed information was integrated with other relevant traffic data and presented graphically on the internet for public use. Statistical trend analysis for the data collected in 1997, 1998 and 1999 are also presented and applications in the overall ITMS are discussed.
