Installation of Intelligent Transportation Systems on US 90 from IH 610 (East Loop) to BW 8 (East Belt) in Harris Co. Texas Department of Transportation 1/12/2015 7:55:35 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, US 90 (Crosby Freeway), from Interstate 610 to Beltway 8 East in Harris County. Specifically, this project will include the installation of 6.5 miles of conduit bank and 144-strand fiber trunkline; including 10 closed-circuit cameras, 2 dynamic message signs, 4 radar-based vehicle sensing devices, and 4 travel time readers. Additionally, this ITS segment improvement 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
Yes Categorical Exclusion (CE) (c)(21) Deployment of electronics, photonics, communications, or information processing No 01/10/2015 No Yes No Utility Adjustments will be needed. No No Public Involvement activities are needed. This project is an ITS project which can be designed quickly. 30% plans can be completed within 30 days of notification to start plans.Map/Location

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. Incident information will be collected from CCTV cameras and information be transmitted through, dynamic message signs, mobile devices, websites and various media outlets. ; 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 Interstate 610 to Beltway 8 East for a distance of 6.5 miles along US 90 (Crosby Freeway) in Harris 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
Yes; This project will provide a fiber network connection between Sam Houston Toll way/BW 8 communications and IH 610 and IH 10 which will provide several communication paths, incase of disruption in the fiber optic network on a connecting freeway. ; Yes; This project will provide a fiber network connection between Sam Houston Toll way/BW 8 communications and IH 610 and IH 10 which will provide several communication paths, incase of disruption in the fiber optic network on a connecting freeway. It will provide redundancy for the Harris County Toll Road authority and Harris County Traffic management networks. It will also provide redundancy to the Port of Houston and Ship Channel Security Systems. ; Yes; This project will provide a fiber network connection between Sam Houston Toll way/BW 8 communications and IH 610 and IH 10 which will provide several communication paths, incase of disruption in the fiber optic network on a connecting freeway thus increasing reliability of the system.;
