Easing Crowded Corridors

Coordinated plans in three Texas cities, eight nationwide, aim to reduce congestion

The Dallas, Texas, proposed corridor is U.S. 75 from from downtown Dallas to SH 121. The corridor includes HOV, tolling, express bus and light rail.

Congestion. It is the bane of the modern, busy and enterprising city. More than just an irritant for commuters, congestion is like a clogged artery that affects every aspect of a city’s “health” from air quality, to the economy, to quality of life.

A unique approach to easing congestion along major travel corridors is being led by the US Department of Transportation (US DOT). Known as Integrated Corridor Management, or ICM, the idea is to assemble a “toolbox” of transportation operational policies, analysis tools and Intelligent Transportation Systems (ITS) technologies that can be tailored to match the infrastructure and the characteristics of different corridors.

US DOT selected eight metropolitan areas nationwide to develop ICM plans for specific corridors. Three of these eight metropolitan areas are in Texas. Dallas, Houston, and San Antonio were selected along with Seattle, San Diego, Oakland, Montgomery County (Maryland) and Minneapolis.

“Transportation agencies in Texas are doing many of the right things to ensure the efficient and safe operation of major corridors,” says Christopher Poe, assistant agency director at the Texas Transportation Institute. “The state is poised to take corridor operations to the next level, and developing these ICM plans will help advance these efforts.”

The Houston, Texas, proposed corridor is I-10 from Loop 610 West to SH 99. The corridor includes HOV, tolling, value pricing, express bus and bus rapid transit.

Poe says that while travelers do not seem to care which agency is operating the part of the transportation system they are using, they do care about getting from point A to point B as quickly as possible.

“ICM plans to help answer questions like, ‘How do all of the agencies along a major urban corridor (e.g., transit authorities, departments of transportation and toll authorities) work together to operate roadways, buses, rail, and traffic lights and utilize other strategies to make things better for the customer?’” says Poe. “Cities, transit agencies, and TxDOT do a very good job managing their own systems, but working together, these agencies can reduce travel times, increase the use of transit, ensure the reliability of roadways and improve air quality. That’s where teamwork comes in.”

Teams in the three Texas cities (see “TTI and Teamwork” sidebar) were formed with transportation planners and experts from TxDOT, transit agencies, communities, stakeholder groups and universities.

The San Antonio, Texas, proposed corridor is I-10 from downtown San Antonio to Loop 1604. The corridor includes express bus, real-time freeway and arterial traffic control.

The eight cities selected nationwide were chosen for stage one of a three stage, long-term project by US DOT. Each site was provided funding to develop a Concept of Operations or operational plan.

US DOT expects to select up to four of the original eight pioneer sites to participate in stage two, which involves funding to analyze and model the proposed operational plans in each corridor developed in stage one.

Stage three, the demonstration stage, will also involve up to four pioneer sites. As much as $10 million will be awarded to demonstrate key ICM strategies estimated to have significant benefit as defined from operational plans and modeling exercises conducted earlier in the initiative.

Teamwork to Fight Congestion

The transportation industry has a history of investing in highway, arterial and transit systems. However, this investment is typically focused on one mode. Texas’s ICM pioneer sites will demonstrate how technology can link routes and modes to leverage available capacity. By managing the individual transportation networks in a corridor as a multimodal system, we can realize significant improvements in managing congestion. Texas’s Pioneer Sites will play an important role in what could become a transformation in America’s approach to congestion management.

DART, TxDOT and the local cities have been working collaboratively on operations for over 20 years. ICM provides new tools to build on those relationships and provide superior service to the customers traveling in corridors such as U.S. 75. In Dallas, we have excellent freeways, HOV lanes, arterials streets, and a state-of-the-art light rail system, but through better information sharing among agencies and to the public, we can allow the traveler to maximize their use of the entire transportation system.

Dallas Area Rapid Transit

The partners in San Antonio’s Integrated Corridor Management team have been working together for many years. The established relationships allow the project team to use their cumulative knowledge of the transportation issues within San Antonio to develop the Concept of Operations and Requirements Document to support the goals of Integrated Corridor Management for the I-10 Northwest corridor.

ICM will help people make pre-trip and en-route decisions based on real-time traffic information. We’re looking at an aspect called “rolling telecommuting,” where some businesses can look at a prediction of heavy traffic for the next day and possibly encourage their telecommuting employees to schedule their telecommute day for the day we’re predicting a bad traffic scenario.

TTI and Teamwork aid ICM in…

DALLAS—TTI Assistant Agency Director Christopher Poe is leading a university team on data collection, modeling, and analyzing the ICM operational strategies for the U.S. 75 Corridor.

Dallas’ ICM Team: Dallas Area Rapid Transit (DART); TxDOT; the Cities of Dallas, Richardson, Plano, University Park, Highland Park; North Central Texas Council of Governments, North Texas Tollway Authority, TTI, Southern Methodist University and University of Texas at Arlington

HOUSTON—TTI Research Engineer Tony Voigt worked with TxDOT to craft the ICM plan for the I-10 west corridor, which runs from the IH-610 west loop, SH 99 in the west, U.S. 290 in the north and the West Park Toll Road in the south.

Houston’s ICM Team: TxDOT, TTI, Houston Metropolitan Transit Authority of Harris County, Harris County, City of Houston, and Houston Galveston Area Council

SAN ANTONIO—TTI Associate Research Engineers Steve Venglar and Cesar Quiroga led the data archiving effort for the I-10, I-35, and Loop 1604 corridor in the Alamo City.

San Antonio’s ICM Team: TxDOT, TTI, City of San Antonio, VIA Metropolitan Transit Authority, and the Southwest Research Institute

“Cities, transit agencies and TxDOT do a very good job managing their own systems, but working together, these agencies can reduce travel times, increase the use of transit, ensure the reliability of roadways and improve air quality. That’s where teamwork comes in.”
