The use of intelligent transport systems (ITSs) in Gahanna, a suburb of Columbus, Ohio in the USA, is described. In the 1980s, controllers manufactured by Econolite Control Products, Inc. were installed. In the 1990s, the city's system was upgraded to Econolite's advanced Windows compliant Aries traffic management software. Gahanna then developed a multiphase ITS master plan. The first phase consisted of the installation of fibre optic communication cable from City Hall to a major intersection, installation of a video detection system and pan, tilt and zoom colour camera system at the intersection. Phase 2 extended the fibre communications plant to the city's western corporation limit and added the new Image Sensing Systems' Autoscope Solo Pro colour video detection system and a second incident-monitoring camera at a second intersection.
