The City of Houston plans to install an automatic vehicle identification (AVI) system to gather real-time traffic information on 370 km (230 mi) of highway and 161 km (100 mi) of high occupancy vehicle lanes in and around Houston. Information on traffic conditions is relayed back to commuters via changeable message signs and radio broadcasts. This article describes the three-phase project, which includes: Phase I-volunteer commuters report traffic conditions; Phase II-limited installation of the AVI system; and Phase III-AVI installation on all major Houston freeways. The system will be the first of its kind in the world and will play a primary role in the operation of Houston's central control facility.
