Digital transportation infrastructure pilots became real — and helped move millions of people around host cities. Policymakers should build on that momentum.

For American cities, the World Cup was more than a sporting event. It was a national stress test.

Across the country, host cities moved unprecedented numbers of fans through streets, sidewalks, highways, stadium districts and downtown corridors, often under intense time pressure and global scrutiny. The result could have been paralysis. But in many places, it was experimentation.

Technologies and systems that had long been stuck in pilot programs, planning documents or procurement limbo suddenly became real. Smart traffic signals, real-time data sharing, lidar-enabled traffic monitoring, new shuttle networks and tournament-specific transit systems moved from “someday” to “game day.”

Innovative digital infrastructure solutions for transportation are here. In many cases, these solutions are faster, better and cheaper than building new physical infrastructure. The question now is whether we treat these innovations as temporary World Cup fixes or as the beginning of a smarter, safer and more efficient transportation future.

In Arlington, Texas, traffic engineers used the World Cup as an opportunity to expand smart signaling to reduce congestion after a successful pilot program. The city deployed the AI-powered platform NoTraffic, an Israeli-developed radar and livestream video detection system that differentiates between vehicle types, cyclists and pedestrians, automatically adjusting signal timing in real time. The $600,000 investment, covering about 30 intersections in the Entertainment District around AT&T Stadium, came after a 2023 pilot triggered by a World Series parade that drew three to four times the crowd.

Kansas City, Missouri, which lacks the direct transit infrastructure of coastal host cities, built a new tournament-specific bus network, Connect KC26, a direct motorcoach service to 15 locations that previously had no public transit access. The city also deployed a smart signaling system to support transportation during the tournament, leaving behind a more responsive traffic-management network designed to improve the safety, efficiency, and reliability of travel throughout the region.
