INVESTIGATION OF SOURCES OF FREEWAY SPEED DATA IN THE DALLAS AREA AND PRESENTATION TO TRAVELING PUBLIC BY ELECTRONIC MEANS

This report documents the analysis of existing sources of freeway operations data in the Dallas Urban Area. Recommendations are made for sampling vehicle detectors to be strategically placed to provide operational data prior to full implementation of a freeway management system. In addition, a procedure for interfacing to 911 emergency services to provide notification and location of freeway incidents not otherwise detected is proposed. A graphical Internet display format is described for presentation of these data to the traveling public.
