A recent study from Southern Methodist University reveals that fully autonomous vehicles could potentially reduce traffic delays in the Dallas-Fort Worth area by as much as 33 percent, without the need for new highway lanes. This finding is particularly relevant for Melissa, Texas, located about 50 miles northeast of Dallas, as it highlights the ongoing advancements in transportation technology in the state.
The research, led by Khaled Abdelghany at SMU's Stephanie and Hunter Hunt Institute for Engineering and Humanity, utilized traffic modeling from the Texas A&M Transportation Institute. The study was partially funded by the region's council of governments.
Researchers conducted 25 experiments simulating traffic conditions in 2045, examining scenarios with 100 percent, 50 percent, and 25 percent adoption of autonomous vehicles compared to a baseline scenario with no driverless cars. In the fully automated scenario, delays decreased by up to 33 percent, with hours spent in congested traffic dropping by at least 19 percent.
The study suggests that human drivers contribute to traffic jams through inconsistent driving patterns, which autonomous vehicles could help alleviate by promoting smoother driving. In 2024, Dallas was ranked as the 17th most congested city in the United States, with drivers losing approximately 36 hours annually due to traffic.
Texas has emerged as a leader in the development of driverless technology, particularly in freight transportation. Aurora Innovation launched the first commercial driverless delivery service between Dallas and Houston in April 2025, operating trucks along the I-45 corridor without human drivers. This route was strategically chosen, as nearly half of all truck freight in Texas travels between these two cities.
Aurora has also introduced a second route from Fort Worth to El Paso and plans to deploy hundreds of trucks.
Several other companies, including Kodiak Robotics and Waymo Via, are also advancing autonomous trucking in Texas, solidifying the state's position as a hub for this industry.
On the passenger side, Waymo has been offering a paid robotaxi service in Austin and expanded its service to select riders in Dallas, Houston, and San Antonio in February 2026, with plans for broader availability by the end of the year.
While the rise of driverless vehicles raises questions about job displacement, experts note that new roles will emerge. Positions such as technicians, remote operators, and maintenance staff will still be necessary to support autonomous operations. Industry analysts project that the autonomous vehicle sector could contribute approximately $70 billion to the U.S. GDP and generate about 9 million jobs globally by 2030.
The study's 33 percent reduction figure is based on a scenario where every vehicle on the road is autonomous, which is not expected to occur in the near term. Research from MIT indicates that many autonomous vehicle operating hours involve no passengers, as vehicles reposition between fares.
