Red light camera systems tend to be the very first approach that a city takes towards "intersection safety". This is wrong.

The Federal Highway Administration and the National Highway Traffic Safety Administration have jointly published the "Red Light Camera Operational Guidelines" (see source #2). These guidelines state that the proper progression to red light cameras is;

1. Intersection Engineering Improvements
Engineering solutions to be considered include, but are not limited to, modifying traffic signal timing, improving signing and marking, improving sight lines, modifying grades and/or grade separation, adjusting the prevailing speeds, changes in surface treatments, altering lane configuration, and replacing the traffic signal with some other form of traffic control device or intersection type.

2. Education
A well-designed public information and education campaign will assist motorists and the general public in understanding the safety issues inherent to red light running. It will provide information and data that explain what red light running is, why red light running is dangerous, and what actions are currently being undertaken to reduce the incidence of red light running.

3. Traditional Enforcement By Law Enforcement Officers
Traditional enforcement efforts by law enforcement officers specifically targeting red light running violators can be a cost effective deterrent in reducing red light violations at problem intersections.

4. Red Light Camera Systems
Red light camera systems can be a cost effective tool to reduce red light violations. Red light camera systems should be part of a comprehensive intersection safety program, which considers all countermeasures to reduce fatal and injury crashes at intersections.

Clearly, cities that install red light camera systems without following this progression violate these guidelines. They also shatter the illusion that their use of these systems is related to traffic safety.
