As I drive around the metro area I see more signs indicating that the intersections have red-light cameras. If public safety were important to the proponents of the cameras, maybe they could alter the green-yellow-red sequence by adding a flashing green a predetermined number of seconds before it changes to yellow. The flashing green would indicate that the green light is “stale.” Stale green lights allow drivers ample time to reduce speed. This would be especially beneficial for big trucks.
Some intersections in the metro area have red-light warning signs some distance back from the intersection. Those are the signs that are illuminated when the intersection ahead will be at a red light as drivers approach the sign. What a great idea! However, I see them installed only at blind intersections such as over the crest of a hill. Those red-light signs must have been quite expensive. Would the flashing green be more cost-effective?
Why not add the flashing green to all intersections? If someone runs a red light with either the illuminated sign or the flashing stale green, they are without a doubt a scofflaw and deserve a ticket!
