Title PROBEX: Data Exchanges for Enhanced Traffic Reconstruction.

Abstract This report describes the results of a project that was initiated under the California-France cooperative research program CalFrance, aimed at identifying compatible research interests among researchers in California and France that could be capitalized upon for future larger research projects. In this way, the small investment of seed resources by the California and French governments could potentially leverage significantly larger resources for future work that would benefit both governments. The Californian and French members of the research teams exchanged technical documents and held seminars and more informal meetings during the project period. It became evident from the shared information, that although they were both working on probe vehicle data collection and analysis, they were starting from the opposite ends of the spectrum in probe data studies. The California probe work has concentrated on arterial applications where very detailed data are needed to support more intelligent traffic signal control strategies, where the latency times are critical. In contrast, the French probe work has concentrated on highway applications with low density data for use in traveler information systems, where the latency times are not nearly as critical. The French work has also concentrated on applications of high-powered mathematical methods for data analysis, while the California work has been based on simple but practical data aggregation techniques. Due to large differences in the technical approaches taken to date and in the underlying probe data sampling environments, the project partners did not find an immediate target project or technical topic for a larger and more integrated collaborative research project. They agreed that they should remain alert for future chances to work together on probe data analysis and for projects at the U.S. Department of Transportation (DOT) and European Commission levels that could support such work.
