A unique public/private venture is underway in Houston, Texas, to improve the accuracy and timeliness of real-time traffic information available to motorists, commercial vehicle operators, and transit agencies. A system is currently under development which utilizes the concepts and technologies of Intelligent Vehicle/ Highway Systems (IVHS) to collect travel time and incident data directly from commuters traveling in the 1-45 (North) Freeway/US-59 (Eastex) Freeway corridor. A fully automated system for collecting information is planned, but until the hardware can be selected and installed, a manual system using cellular telephones will be used. Traffic and incident information will be made available to motorists, commercial fleet operators, and transit agencies through a variety of communication mediums, including changeable message signs located at key diversion points in the corridor and direct line connections to dispatching centers of transit and commercial fleet operations.
