We have developed a field prototype of a laser-based non-intrusive detection system for real-time measurement of delineations of moving vehicles for highway testing, based on our previous research on the laboratory prototype of the system. The primary goal of this project is to develop a roadway...

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...

This report describes the outcome of a set of experiments undertaken to assess the net benefits of ITS applications in a stylized urban and near urban highway network.

The introduction of electronic toll collection on the eight bridges crossing San Francisco Bay has provided the means for a relatively simple and low cost system for measuring travel times on many Bay Area bridges and roads. The toll tags sued for electronic toll collection can be read by...

This paper calibrates on-line the parameters of a controller-estimated driver behavior model used in a deployable behavior-consistent approach for real-time route guidance by checking the consistency between the time-dependent actual and estimated system states. The behavior model has a fuzzy...
