Michigan is constructing the nation’s first smart highway. A three-mile stretch of Interstate 94 will be transformed into a smart highway, thanks to the Alphabet-backed startup Cavnue. This pilot project, located between Ann Arbor and Detroit, Michigan, could potentially inspire similar construction projects across the country.
The smart highway is essentially a large, long-tracking system for Michigan’s Department of Transportation (MDOT) and drivers on the highway. It is designed to alert both MDOT and drivers about potential issues ahead, such as obstacles in the road, accidents, or traffic jams. The ultimate goal is to alleviate traffic congestion, prevent accidents, and enable efficient responses to roadway emergencies.
The smart highway operates with a series of poles placed every 200 meters along the road. These poles hold sensor pods, compute pods, and communication equipment. Cameras along the highway monitor every stretch of roadway and take images that are analyzed by AI and machine learning algorithms to identify hazardous driving conditions. Alerts are then sent to MDOT and drivers connected to the roadway.
Cavnue’s technology can connect with any vehicle that has connectivity features. Most modern cars with built-in navigation features fit into this category. The smart highway project is expected to extend to 40 miles in six more phases, connecting Ann Arbor and Detroit once the pilot program is complete.
