The objective of this research project was to explore the benefits of an intelligent transportation system (ITS) field cabinet communication design using local area network concepts and Ethernet technologies. Two products were required for this project: (1) technology demonstration for TxDOT staff, and (2) technical report addressing the cabinet architecture choice and the concept of operation of an Ethernet cabinet. The technologies developed in this project will be employed as a wireless-based and fiber-based Ethernet network in the Laredo District on the TxDOT Camino Colombia Toll Road as well as the existing Laredo metropolitan area ITS network. Through field implementation, the developed architecture will enable the development of TxDOT standards and specifications for low-cost, low-maintenance, high-capacity ITS communications network options primarily for ITS deployments in smaller districts, but will also be applicable for deployments in larger districts. In addition, it is expected to provide insight into options for monitoring and managing small toll-based road segments throughout the state. |
