Real-Time Travel in Work Zones Measured

Abstract:

Computer Recognition Systems, Inc. (CRS) has completed the installation of a work zone real-time travel time measurement system for Kiewit Western Company and Arizona Department of Transportation for use on Highway Route 68. The system consists of two license plate reading stations separated by 13.7 miles. This length of construction travel time is calculated by time stamping and reading license on the roadside plate reading units. The information is sent over a newly constructed hybrid wireless network from the remote units to a Travel Time server where it is calculated and disseminated. The travel time information is used to measure the delays caused by construction and as a tool to gain baseline knowledge about traffic conditions. The system operates in the extreme desert conditions of Arizona on a 24/7/365 basis.
