In about a month, the city of Marysville, California
will test the country's first "smart" red light system, which is designed to predict and prevent traffic collisions at intersections. According to Sacramento's Fox 40 News, the city has incorporated predictive software into an existing red-light camera system, which is located at the intersection of 3rd and F streets. The system predicts when an approaching driver is most likely to run the red light, and it holds traffic coming from other directions until the unlawful car zips safely (and illegally) past. If there isn't a threat of somebody running the light, the intersection lights will just operate as usual.
From the beginning, traffic cameras were meant to make intersections safer by discouraging drivers from running red lights and ticketing those who violated the law. Despite these fines and threats, some people will always break the rules of the road, which is why the preventative aspect of this "smart" red light is so important. It's a much more active way to prevent collisions. The one or two additional seconds a driver might wait at the intersection could literally be the difference between life and death.

Things have gotten so desperate in Marysville that in November they had to shut off half the street lights in town. I wonder if someone will study how that affects crime and accidents.
Don't drop your guard when you're driving in Marysville. The new collision avoidance equipment will protect you from drivers running the light a fraction of a second late (who are no threat anyway), but it can do nothing about the impaired or distracted drivers running the red three or more seconds late - and those are the ones who will kill you.
Collision avoidance is not new, by the way. It just never caught on elsewhere, likely because other potential customers recognized it as a sales gimmick. In Marysville, the gimmick worked - it got the council to keep the cameras, and to pay way too much for them, too.

Empirical studies by several universities indicate that RLCs do not prevent colliions at intersections and in fact are the cause of more rear end collisions. The only thing that RLCs do is provide a evenue source to municipalities. To increase safety at intersections, experts suggest lengthing the yellow light 2 seconds.
