Installation of Arterial Intelligent Transportation Systems on SH 6 from IH 10 to US 290 in Harris Co. Texas Department of Transportation 1/12/2015 9:41:09 AMProject Narrative
This project will provide necessary expanded coverage of existing incident management, congestion management, and traveler information systems infrastructure for the TxDOT Houston District (TranStar) region. This improvement project will allow TranStar to move closer to achieving the goal of DISTRICT-WIDE integrated coverage. Harris County Traffic would benefit from this project for redundant communications. This route is a major hurricane route. There are 24 signals along this route that need to be coordinated. This project will improve real-time incident detection, responsiveness and notification; and also improve real-time traffic monitoring and reporting capabilities of recurring congestion. This project will provide real time monitoring for a major hurricane evacuation route. Harris County Traffic would benefit from this project for redundant communications. The project will involve instrumentation of a principal arterial, SH 6, from Interstate 10 to US 290 in Harris County. Specifically, this project will include the installation of 11 miles of conduit bank and 144-strand fiber trunkline; including 11 closed-circuit cameras, 4 dynamic message signs, and 12 travel time readers. This project will provide communications to 24 signals. Additionally, this ITS segment improvement will better serve an existing regional evacuation route and provides for fiber-optic communication redundancy. None. However, since this is an ITS infrastructure expansion versus conventional roadway capacity expansion, the inherent benefit is to gain more capacity utilization of the existing facility without any environmental impacts or requiring additional right-of-way/heavy construction.Project Narrative

Congestion Safety
Incident/Event Management
Yes; This ITS project improvement segment will be a fully-integrated extension of TxDOT’s current ITS system operated out of the region’s multi-agency housed Traffic & Emergency Management Center (Houston TranStar). ; Yes; This ITS project improvement segment is both on the National Highway System and a component on H-GAC’s CMP Network. ; Yes; This ITS project improvement segment will include the installation of 4 dynamic message signs and 12 travel time (Bluetooth) readers that provide updated traveler information on TranStar’s speed map and email alert free subscription service. ; No; However, through the extension of ITS instrumentation (i.e., CCTVs, RSVDs, and travel time readers) emergency vehicles can be routed more efficiently during their incident arrival and departure tripmaking. ; No; However, through the extension of ITS instrumentation (i.e., CCTVs, RSVDs, and travel time readers) mobility management for the OVERALL travel corridor will be improved.; Yes; This project will improve real-time incident detection, responsiveness and notification; and also improve real-time traffic monitoring and reporting capabilities of recurring congestion. This project will also interconnect the signals along SH 6. This will provide the synchronization, real time monitoring and remote access capability to the signal system along the corridor, thus maximizing the throughput of traffic. ;Coordination
System Migration/Expandability
Yes; The system will expand/extend the regional communications network from Interstate 10 to US 290 for a distance of 11 miles along SH 6 in Harris County. It will allow for connections to Harris County Fiber and provide redundancy to IH 10 and US 290.; Yes; This ITS project improvement will be fully-integrated into the region’s Traffic and Emergency Operations Center (Houston TranStar). This will allow all real-time traffic and incident information to be viewed and shared among the principal transportation and emergency management agencies in Harris County (TxDOT, Harris County, City of Houston, and METRO).;Integration and Information Sharing
AND, System ties into another agency’s systems to allow for the sharing of data; All information and data captured by this ITS improvement project will be transmitted to the region’s Traffic and Emergency Management (Houston TranStar). Since all information and data will be coming into TranStar, the capability for sharing among the primary TranStar partners is inherent. It will allow connections to the Harris County Fiber network. ; Yes; The system will provide data to Houston TranStar website, TxDOT website, Dynamic Message Signs via TranStar operators, local media outlets, and free individual subscription service for customized email alerts.; Yes; The system will collect segment speed and travel time data that can be used for mobility performance measures. Additionally, the system will assist in the real-time monitoring of incidents providing the necessary time increments to define total clearance timelines by various types of incidents to report incident clearance performance. Data from the signals vehicle detection will be integrated and can be used for performance measures. ;Asset Mgmt/Efficient Operations
Continuity Operations
Yes; This ITS improvement project will expand the general area of real-time coverage/monitoring of traffic and traffic incidents, thereby providing a greater capability to minimize any disruption due to recurring or non-recurring congestion. ; Yes; This project is an important leg in the connection to US 290. This project extension will continue a path along SH 6 and provide for a redundant ring to Beltway 8 and Interstate 610 Loop. ; Yes; This project improvement will provide expanded monitoring and communication for the region, thereby allowing more mobility benefits to be available to a greater number of travelers.;
