Installation of Arterial Intelligent Transportation Systems on SH 6 from Ft. Bend Co. line to SH 288 in Brazoria County Texas Department of Transportation 1/12/2015 12:01:31 PMProject 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. This corridor is a major hurricane evacuation route. This segment will also provide a redundant path for SH 288 and US 59. The Cities of Missouri City and Sugar Land would benefit from this project. Ft. Bend County Toll Road and Harris County Toll Road would also benefit from this project. There are five signals on this segment of the roadway that need to be coordinated with other TxDOT signals, Missouri City and Sugar Land signals to allow maximum throughput of the traffic. This project would enhance the monitoring and traffic flow efficiency of a hurricane evacuation. 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 a vital link for providing redundant connections between Missouri City and Houston TranStar. This project will provide a vital link for providing redundant connections between the City of Sugar Land and Houston TranStar. This project will provide a vital link for providing redundant connections between the Ft. Bend Toll road, Harris County Toll road Authority and Houston TranStar. There are three signals on this segment of the roadway that need to be coordinated with Missouri City and Sugar Land signals to allow maximum throughput of the traffic. This project would enhance the monitoring and traffic flow efficiency of a hurricane evacuation. The project will involve instrumentation of a principal arterial, SH 6, from the Ft. Bend County Line to SH 288 in Brazoria County. Specifically, this project will include the installation of 3.2 miles of conduit bank and 144-strand fiber trunkline; including 6 closed-circuit cameras, 2 dynamic message signs, and 4 travel time readers. Five signals will be interconnected. 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 2 dynamic message signs and 4 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; This project will provide a vital link for providing redundant connections between Missouri City and Houston TranStar. This project will also provide a vital link for providing redundant connections between the City of Sugar Land and Houston TranStar. This project will provide a redundant connections between the Ft. Bend Toll road, Harris County Toll road Authority and Houston TranStar. This project will enable the connection between SH 288 and US 59.; 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. This project will provide a vital link for providing redundant connections between Missouri City and Houston TranStar. This project will provide a vital link for providing redundant connections between the City of Sugar Land and Houston TranStar. This project will provide a vital link for providing redundant connections between the Ft. Bend Toll road, Harris County Toll road Authority and Houston TranStar. ; 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. Signal vehicle detectors will also provide performance data. ;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. This project will provide a vital link for providing redundant connections between Missouri City and Houston TranStar. This project will provide a vital link for providing redundant connections between the City of Sugar Land and Houston TranStar. This project will provide a vital link for providing redundant connections between the Ft. Bend Toll road, Harris County Toll road Authority and Houston TranStar. ; Yes; This project will provide a vital link for providing redundant connections between Missouri City and Houston TranStar. This project will provide a vital link for providing redundant connections between the City of Sugar Land and Houston TranStar. This project will provide a vital link for providing redundant connections between the Ft. Bend Toll road, Harris County Toll road Authority and Houston TranStar. This also will provide a connection between SH 288, Ft. Bend Toll way and US 59. ; Yes; This project will provide a vital link for providing redundant connections between Missouri City and Houston TranStar.
