System Selection and Technologies

The most widely used red light camera systems employ film-based cameras and inductive loop vehicle detection technologies. However, other red light camera technologies have become available over the past five years, most notably technologies that employ digital camera equipment where photographic data, including streamed video clips, may be immediately downloaded for processing using leased telephone line or microwave communications. Additionally, red light camera systems that use video-based and radar vehicle detection methods as well as systems that employ overhead camera placements and floodlighting equipment as an alternative to the curb-based placements used by many State and local agencies are being tested.

A red light camera system consists of the following on-the-street components:

· Camera Units;
· Intersection Lighting;
· Camera Housing and Supporting Structure;
· Vehicle Detection;
· Communications; and,
· Warning Signs.

Each of these components is reviewed in the following sections:
