North America smart highway market was valued at $30.5 billion in 2025 and is projected to reach $164.7 billion by 2035, growing at a CAGR of 18.5% during the forecast period (2026–2035). The growing number of pilot projects, along with the rising adoption of connected and autonomous vehicles, is significantly driving the demand for the North American smart highway market. For instance, Driverless semi?trucks are now being tested or operated on the SH 130 Smart Freight Corridor in central Texas, supported by smart infrastructure enhancements in partnership with TxDOT and Cavnue.

As companies are focusing on developing fully autonomous vehicles and this advanced technology needs a smart supporting solution. For instance, autonomous vehicles need real-time hazard alerts, and as compared to normal roads, smart roads can detect accidents or debris kilometers ahead and send this data directly into the vehicle's computer so that a timely reroute can be taken by the vehicle even before the sensor detects this obstacle.
Secondly, smart highways have machine-readable markings that use highly reflective, sensor-compatible lane markings so that autonomous vehicle cameras can detect them even in adverse weather, unlike normal highways, whose paint markings may fade along with time and can create issues for autonomous vehicles.
Furthermore, the usage of edge computing by smart highways acts as an enhanced safety feature of the autonomous vehicle. A car’s sensors (LiDAR/Radar) only see what is in front of it, and in case it gets covered by a large object, it cannot see anything. So, in this case, collective intelligence solves this by using the roadside unit (RSU), the roadside camera detects it and broadcasts an alert to all the autonomous cars via the edge node, even before the car sensor senses it.
