Urban freeways are undergoing significant changes due to reconstruction and rehabilitation of roadways to increase the capacities, to provide for High Occupancy Vehicle (HOV) operations, and to repair damaged and worn-out pavements and structures. There is a need for large quantities of timely and comprehensive data on traffic and travel conditions in order to effectively implement these changes. The State Department of Highways and Public Transportation (SDHPT) does not now collect these types of data as part of their state-wide traffic data aquisition program. This project investigates the development of an urban data collection system that employs district personnel to operate automatic traffic recorders on an expanded network of loop detectors embedded in the roadways. The system emphasizes automatic collection and analysis equipment and permanently installed sensors to reduce the manpower requirements.
