Several U.S. cities are piloting a traffic signal strategy known as ‘rest in red’ to combat speeding and improve road safety. Unlike traditional systems, this technology defaults signals to red and uses sensors to detect approaching vehicles. Drivers who adhere to the posted speed limit are rewarded with earlier green lights, while those speeding are forced to wait longer at red lights.

Initial implementations in Albuquerque, New Mexico, and Portland, Oregon, have shown positive results. In Portland, average speeds on tested corridors dropped from 39 mph to the 30 mph limit. Albuquerque reported a significant decrease in accidents and injuries on specific avenues. 

Broader trials in other locations, such as North Carolina, have led to a 43% reduction in overall accidents. While some critics express concern regarding potential increases in red-light violations, proponents describe the system as a ‘virtual speed bump’ that incentivizes safe driving through rewards. The strategy has been tested or utilized in various cities, including Long Beach, California, and Boulder, Colorado.
