Khaled Abdelghany<\/a>\u00a0describes autonomous vehicles as a “big elephant” coming to North Texas roads.\u00a0Yet\u00a0the SMU civil and environmental engineering professor\u00a0does not expect them to\u00a0account for more\u00a0than about\u00a010% of traffic by 2045 unless\u00a0the\u00a0technology\u00a0advances significantly\u00a0and\u00a0gains wider public acceptance.<\/p>\n

But Abdelghany says the effects could\u00a0extend\u00a0beyond traffic, reshaping where people live and work, how lower-income residents get around and how passengers connect to public transportation.<\/p>\n

The study<\/a> was partially funded by the\u00a0North Central Texas Council of\u00a0Governments\u00a0and published in the Journal of Urban Technology. This conversation\u00a0with Abdelghany\u00a0has been condensed and edited for clarity.<\/p>\n

How could autonomous vehicles reduce D-FW congestion without adding highway lanes?<\/p>\n

Abdelghany: The main short-term benefit is making better use of the lanes we already have. Vehicles driven by robots could coordinate their speeds and movements. We call this speed harmonization. You can think of a platoon of vehicles moving together like a train at a steady speed.<\/p>\n

Today, drivers travel at different speeds and have different reaction times. That creates instability and what we call flow breakdown. Sometimes traffic slows to a\u00a0crawl,\u00a0drivers assume there must be a crash ahead and then find nothing. The slowdown was caused by instability in the traffic.<\/p>\n

Connected vehicles could communicate with each other, agree on\u00a0a speed\u00a0and keep traffic flowing more steadily. That could increase how many vehicles a highway can accommodate without adding more concrete.<\/p>\n

You\u00a0expect autonomous vehicles to\u00a0represent\u00a0only about 10% of traffic by 2045. Why did the study examine\u00a0scenarios\u00a0reaching 100% adoption?\u00a0<\/p>\n

Abdelghany:\u00a0In one experiment with 100% adoption, the model estimated a 33% reduction in total daily traffic delay. Delay means the\u00a0additional\u00a0time spent traveling under congested conditions compared with free-flow conditions, such as driving the same route at 2 a.m.<\/p>\n

That is why we examined different adoption rates. Even at 25%, the model found benefits, although mixing autonomous vehicles with human-driven vehicles creates another challenge. One idea under consideration is\u00a0establishing\u00a0dedicated technology lanes,\u00a0similar to\u00a0HOV lanes, to separate the two types of traffic.<\/p>\n

How could autonomous vehicles increase the number of miles traveled while reducing congestion?<\/p>\n

Abdelghany:\u00a0People may become more willing to travel longer distances because they will no longer have to concentrate on driving. The vehicle could become an office, game\u00a0room\u00a0or another place where passengers do something useful. Someone working in downtown Dallas, for example, may become more willing to live in a distant suburb.<\/p>\n

That could also change where businesses\u00a0locate. If workers move farther out, employers and services may follow them. Over several decades, autonomous vehicles, remote\u00a0work\u00a0and digital connectivity could reshape where people live and work across the region.<\/p>\n

Could\u00a0robotaxis make transportation more affordable, or could they deepen existing mobility gaps?<\/p>\n

Abdelghany:\u00a0The future transportation system could include large fleets of robotaxis\u00a0operated\u00a0by competing companies. Instead of owning and\u00a0maintaining\u00a0a car, someone could request a vehicle through an app. Competition among those companies could make transportation more affordable.<\/p>\n

But there is also an equity concern. The vehicles could concentrate in parts of the region where demand and profitability are highest. Someone in one area may receive a vehicle in two minutes, while someone in southern Dallas waits much longer because fewer vehicles are available. Prices may improve while the quality and reliability of service remain unequal.<\/p>\n

Robotaxis could also help solve public transportation\u2019s first- and last-mile problem by taking passengers to and from rail stations. That would require public agencies and private transportation companies to coordinate their services.<\/p>\n

What is the biggest misconception readers should avoid when interpreting the study?<\/p>\n

Abdelghany:\u00a0The numbers should not be treated as precise predictions. This is a long-term planning study based on assumptions about\u00a0the technology, adoption\u00a0rates\u00a0and travel behavior.<\/p>\n

The 33% reduction is not a promise. It is the model\u2019s estimate under a particular set of assumptions.\u00a0As we learn more about autonomous vehicles and how communities adopt them, those assumptions and estimates will need to be updated.\u00a0This study describes\u00a0possible futures, not a fixed forecast.<\/p>\n
