From guardrails to potholes, AI is becoming the new eyes on America’s roads

Article content

As America’s aging roads fall further behind on much-needed repairs, cities and states are turning to artificial intelligence to spot the worst hazards and decide which fixes should come first.

Hawaii officials, for example, are giving away 1,000 dashboard cameras as they try to reverse a recent spike in traffic fatalities. The cameras will use AI to automate inspections of guardrails, road signs and pavement markings, instantly discerning between minor problems and emergencies that warrant sending a maintenance crew.

“This is not something where it’s looked at once a month and then they sit down and figure out where they’re going to put their vans,” said Richard Browning, chief commercial officer at Nextbase, which developed the dashcams and imagery platform for Hawaii.

After San Jose, California, started mounting cameras on street sweepers, city staff confirmed the system correctly identified potholes 97% of the time. Now they’re expanding the effort to parking enforcement vehicles.

Texas, where there are more roadway lane miles than the next two states combined, is less than a year into a massive AI plan that uses cameras as well as cellphone data from drivers who enroll to improve safety.

Other states use the technology to inspect street signs or build annual reports about road congestion.

Every guardrail, every day

Hawaii drivers over the next few weeks will be able to sign up for a free dashcam valued at $499 under the “Eyes on the Road” campaign, which was piloted on service vehicles in 2021 before being paused due to wildfires.

Roger Chen, a University of Hawaii associate professor of engineering who is helping facilitate the program, said the state faces unique challenges in maintaining its outdated roadway infrastructure.

“Equipment has to be shipped to the island,” Chen said. “There’s a space constraint and a topography constraint they have to deal with, so it’s not an easy problem.”

Although the program also monitors such things as street debris and faded paint on lane lines, the companies behind the technology particularly tout its ability to detect damaged guardrails.

“They’re analyzing all guardrails in their state, every single day,” said Mark Pittman, CEO of Blyncsy, which combines the dashboard feeds with mapping software to analyze road conditions.

Hawaii transportation officials are well aware of the risks that can stem from broken guardrails. Last year, the state reached a $3.9 million settlement with the family of a driver who was killed in 2020 after slamming into a guardrail that had been damaged in a crash 18 months earlier but never repaired.

In October, Hawaii recorded its 106th traffic fatality of 2025 — more than all of 2024. It’s unclear how many of the deaths were related to road problems, but Chen said the grim trend underscores the timeliness of the dashboard program.
