Installation of Intelligent Transportation Systems on IH 45 from League Line Rd to Walker County Line in Montgomery Co. Texas Department of Transportation 1/12/2015 7:41:20 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. This project will improve real-time incident detection, responsiveness and notification; and also improve real-time traffic monitoring and reporting capabilities of recurring congestion. The project will involve instrumentation of a freeway, I-45 (North Freeway), from League Line Road to the Walker County Line in Montgomery County. Specifically, this project will include the installation of 10 miles of conduit bank and 144-strand fiber trunkline; including 20 closed-circuit cameras, 2 dynamic message signs, 5 radar-based vehicle sensing devices, and 10 travel time readers. Additionally, this ITS segment improvement will better serve an existing regional evacuation route. 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
Yes Categorical Exclusion (CE) (c)(21) Deployment of electronics, photonics, communications, or information processing No 01/07/2015 No Yes No Utility Adjustments will be needed. No No Public Involvement activities are needed. This is an ITS project that can be at 30% completion within 30 days of notification to start..Map/Location

H-GAC to conduct analysis based on the GIS/map project location and project scope information provided above.
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 10 travel time (Bluetooth) readers that provide updated traveler information on TranStar’s speed map and email alert free subscription service. Camera Images will be made available on the website and mobile devices to view traffic conditions. Information about incidents obtain from cameras ; 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 provide the communication and monitoring infrastructure foundation for the future implementation of integrated corridor management applications such as ramp metering, variable speeds, variable pricing, etc. However, immediate benefits of this project will provide for traffic condition monitoring that will enhance travel time reporting and tripmaking reliability. ;Coordination
System Migration/Expandability
Yes; The system will expand/extend the regional communications network from League Line Road to the Walker County Line for a distance of 10 miles along I-45 North Freeway in Montgomery County.; 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.; 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.;Asset Mgmt/Efficient Operations
Continuity Operations
No; This project extends the ITS Network infrastructure. However at this time it does not tie into any other fiber network. It will provide a future connection for future ITS for Montgomery county and Walker Counties. ; Yes; This project is an important leg in the connection to Montgomery County, Walker County and the TxDOT Bryan District. This project extension will continue a path along Interstate 45 North northward. ; 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.;
