Estimating the speed-crash relationship has long been a focus area of interest in roadway safety analysis. Because of many confounding factors that may influence both speeds and crashes, the relationship cannot be appropriately established without considering the corresponding roadway characteristics and accounting for their effects on speeds and crashes. Texas A&M Transportation Institute researchers Eun […]

TTI Researchers Receive U.S. Patents for Pedestrian Safety, Traffic Data Systems
TTI researchers Tony Voigt, Mike Vickich and Micah Montoya received U.S. patent no. 10,535,262 on Jan. 14, 2020, for an active pedestrian warning system for rail and bus transit routes. Pedestrians distracted near vehicles on the road are at risk for injuries and fatalities in the event of a collision. Both drivers and pedestrians are responsible […]
TTI’s Pedestrian Hybrid Beacon Study Wins National Award
An Arizona Department of Transportation research study, conducted by the Texas A&M Transportation Institute, about pedestrian hybrid beacons received a national award from the American Association of State Highway Transportation Officials (AASHTO). The study (external link) evaluated the pedestrian hybrid beacon (external link), which is a traffic control device that increases drivers’ awareness of pedestrians […]
Transportation Planning in Texas Has Deep Roots Thanks to TxDOT/TTI Relationship
Newest Planning Software Receives Enthusiastic Applause A little known but decades-long relationship between the Texas Department of Transportation (TxDOT) and the Texas A&M Transportation Institute (TTI) is suddenly and steadily emerging thanks to the development of a travel demand-model application tool. The tool is the Texas Package Suite of Programs (simply known as TexPACK), and […]
Post-COVID Transportation Planning Demands the Right Data, Not Guesswork
By Johanna Zmud When will people start vacationing? How many will stick with work-from-home routines? Will online grocery shopping be a fading fad or an enduring trend? The answers to these and other related questions have big implications not only for how Americans live and work after the current crisis, but also for how they […]
Two Decades of Super 2 Research and Implementation for TxDOT Continues to Produce Benefits
With more than 57,000 miles of two-lane rural highways in Texas — where it’s estimated that 68 percent of rural travel occurs — Texas drivers are known to pull onto the shoulder to let a vehicle pass, sometimes creating an unsafe situation. Developing and increasing use of low-cost roadway safety and capacity improvements are key […]
TTI Research Supports El Paso County’s Efforts to Coordinate, Enhance Regional Transit Service
El Paso, Texas, holds a number of distinctions: the state’s only major city in a separate time zone, the only city that borders both a foreign country and another U.S. state, and perennial bragging rights as one of the nation’s safest cities. But when it comes to public transportation, the El Paso region is pretty […]
Why Maintaining a Lone Desert Highway Matters to Us All
By Katherine F. Turnbull For all of the contrasts that distinguish urban and rural Texans, one thing that unites us all is the need for reliable transportation. Exactly what that reliable transportation looks like depends on where we choose to live. Regardless of that choice, certain interests and challenges are commonly shared. Safety and mobility are at […]
Geiselbrecht Receives New Public Participation Certification
Tina Geiselbrecht, research scientist at the Texas A&M Transportation Institute (TTI), has become one of the first people in the United States to become a Certified Public Participation Professional (CP3) as designated by the International Association for Public Participation (IAP2). IAP2 is a professional association “whose members seek to promote and improve the practice of […]
Kuhn Receives ITE’s Matson Award
Beverly Kuhn, senior research engineer with the Texas A&M Transportation Institute (TTI), is the recipient of the Theodore M. Matson Memorial Award. Kuhn received the award at the Institute of Transportation Engineers (ITE) Annual Meeting in August. The prestigious Matson Award is given annually to those considered pioneers in their engineering professions. For Kuhn, transportation […]
Slower Doesn’t Always Mean Safer — NCHRP Guide Helps Planners Mitigate Work Zone Crashes
Roadways don’t build themselves. They require careful planning, construction and regular maintenance, all of which require work zones designed to keep both workers and travelers safe. Sometimes those measures fail. According to the Texas Department of Transportation (TxDOT), in 2017, there were 27,148 work zone crashes in Texas. Of those, 199 were fatalities, and 813 […]
TTI’s Center for Ports and Waterways Helps Sponsors Navigate Economic Opportunity
The Texas Marine Transportation System includes 1,000 harbor channels; 25,000 miles of inland, intracoastal and coastal waterways; and 3,700 terminals handling passenger and cargo movements. And it connects with 152,000 miles of rail, 460,000 miles of pipelines, and 45,000 miles of interstate highways. With 11 deepwater seaports as international gateways and more than 1,000 miles […]
Better Estimates, Smarter Development: Caltrans Adopts TTI’s New Smart-Growth Trip-Generation Tool
The traditional data used to estimate the transportation impact of urban development are not appropriate for smart growth or infill development, according to a study conducted by the Texas A&M Transportation Institute (TTI) for the California Department of Transportation (Caltrans). (Infill development refers to building on vacant land within a developed area.) As a result […]
Using Big Data to Improve Traffic Counts
For years, Gene Hicks thought there had to be a better way to count the number of vehicles traveling his state’s roadways. As director of the Minnesota Department of Transportation’s (MnDOT’s) Traffic Forecasting and Analysis Section, Hicks oversees the tedious task of laying out road tubes at approximately 33,000 sites (about 12,000 each year) to […]
Innovative Data Applications Improve Border Planning, Air Quality
Using GPS Devices to Get Better Emissions Estimates The World Trade Bridge crossing in the Laredo–Nuevo Laredo region is the most used Texas-Mexico port of entry (POE). The crossing’s popularity helps explain the location’s relatively high vehicle emissions, caused by high truck volumes and slow speeds as traffic makes its way across the bridge. A […]
Helping Agencies Manage Infrastructure Renewal: TTI’s Asset Management Group
As in 2013, ASCE once again rated America’s infrastructure a D+ in its latest 2017 assessment. Although several categories, such as ports and rail, achieved modest improvements, others declined. And six core categories that many think of when they think of infrastructure itself — including bridges, roads and aviation — remained unchanged from four years […]
The Texas 100: Texas Leads the Way in Data-Driven Performance Measures
In 2009, researchers at the Texas A&M Transportation Institute (TTI) began compiling its Texas 100 Most Congested Highways list as part of an interagency contract with the Texas Department of Transportation (TxDOT). Over the past nine years, the list has helped TxDOT identify and begin to address the most congested highways in the state. It’s […]
Transportation Leaders Explore Congestion, Funding, Alternative Modes at Policy Symposium
Roadway congestion challenges and solutions were front and center on November 3 as transportation policy followers gathered for a symposium hosted by the Texas A&M Transportation Institute (TTI) and the Texas Tribune. Throughout the morning, policy makers and other leaders stressed the need for careful planning in anticipation of continued rapid population growth, most of […]
TTI Researchers Find Innovative Ways to Use Rural Transit to Move People and Goods
Texas is a big state. Serving the mobility needs of rural residents is important. Public transit plays a key role in getting people where they need to go and might play a future role in getting goods to people. As part of a Texas Department of Transportation (TxDOT) project, researchers at the Texas A&M Transportation […]
Papal Visit Provides Vital Data for El Paso’s Transportation Planners
Major events typically produce major traffic issues, but when Pope Francis visited the El Paso/Juarez area in February, that wasn’t the case at all. Researchers with the Texas A&M Transportation Institute (TTI) used data provided by INRIX, a leading provider of historical, real-time and predictive traffic information, to monitor congestion during the Pope’s visit. Using […]
