An Intelligent Transportation System (ITS) is comprised of an infrastructure within the transportation network involving information processing, communications, and electronics technologies designed to improve overall safety and operational characteristics. The emerging technologies represent how transportation agencies are addressing the increasing demands placed on existing transportation network in order to provide for the safe and efficient movement of people, goods, and services in rural and small urban areas as well as large metropolitan areas. Presently there is limited use of available ITS technologies in rural and small urban Texas Districts. While these Districts account for a large majority of the landmass in Texas, they make up a small percentage of the actual deployment of ITS technology. By contrast, TxDOT's urban Districts have begun to develop ITS on the transportation network encompassing their boundaries. This paper contains a current state-of-the-practice regarding small and urban ITS technologies in Texas and other states. |
