This paper reports on the first phase of the location technology evaluation for probe vehicles. Two technologies were evaluated, Global Positioning Systems (GPS) and the cellular phone tracking technology developed by US Wireless. Although GPS has shown great potential for vehicle probes, much...

Stop line detectors are one of the most deployed traffic data collection technologies at signalized intersections today. Newly emerging probe vehicles are increasingly receiving more attention as an alternative means of real-time monitoring for better system operations, however, high market...

Transportation Management Centers (TMCs) are focal points for monitoring and operating traffic management systems. As new technologies are developed through research in Intelligent-Vehicle- Highway Systems (IVHS), these TMCs will assume increasingly more importance as command and control centers...

The objective of this study is to develop a methodology for incident duration prediction. The authors first developed an understanding of factors that influence incident duration. A series of truncated regression models is used to predict incident duration. The models account for the fact that...

This research investigates methodologies for fusing and further processing real-time road traffic data collected by probe vehicles and induction loop detectors in order to obtain relevant traffic information that is essential for effective deployment of Advanced Traffic Management Information...

This document presents the final report on a project focusing on new traffic sensor technology, mainly video cameras, for traffic surveillance and detection. It describes a Transportation Management Center (TMC), designed for the collation and computation of multi-site statistics. The report...

In this report, the authors describe a method of collecting real-time traffic data from probe vehicles automatically sending traffic reports to one or m ore base stations, connected to a traffic center by a wired communications network. Analyzing and computing road traffic and message traffic...
