Installation of Arterial Intelligent Transportation Systems on SH 146
IH 45 South to SH 96
This project will provide necessary expanded coverage of Intelligent Transportation Systems on SH 146 to provide incident management, congestion management, and traveler information systems for the TxDOT Houston District (TranStar) region. This improvement project will also allow TranStar to move closer to achieving district-wide integrated coverage. The fiber connection will enhance reliability and provide communications network redundancy and continuity of operations for IH45 South and NASA 1.
This project will involve instrumentation of SH 146 with Intelligent Transportation Management Systems devices and traffic signal integration to improve real-time monitoring and reporting capabilities. Specifically, this project will include the installation of approximately 15 miles of fiber optic cable, closed circuit cameras, dynamic message signs, vehicle sensing devices, and travel time readers. Additionally, this ITS segment improvement will better serve an existing regional evacuation route and provide fiber optic communication redundancy.
This project will improve real-time incident detection, responsiveness, notification, real-time monitoring, and incident response. This project will contribute to identifying recurring and non-recurring congestion, creating reliable travel times to improve safety, efficiency, and improving the quality of life for road users experiencing delays.

This project will provide the necessary expanded coverage of existing incident management, congestion management, and traveler information systems infrastructure for the TxDOT Houston District, Houston TranStar partnership.
This project will provide real-time incident detection, responsiveness, and notification to facility users by messaging on Dynamic Message Signs.
The proposed system would tie into Houston TranStar, the region's Transportation Management and Emergency Management center. Other than the four government agencies that comprise the consortium, numerous local government agencies have agreements for sharing resources at Houston TranStar.
This project would provide communications redundancy between IH45 South and Nasa Road One. With other projects, it will also provide communications paths to SH 225 and SH 288.
