Abstract: Speed and delay studies are performed routinely on urban street networks. The data are used for a variety of transportation engineering purposes including signal timing design, roadway construction program formulation, and evaluation of traffic engineering improvements. This paper describes the hardware and software components of a system designed to collect speed and delay data using a moving vehicle. It explains the data collection concept and presents an example of a simple data collection run from the user's point of view. It concludes with a discussion of the existing data analysis capabilities and the potential for the development of a permanent area-wide data base of travel time history.
