Summary Information

The city of Indianapolis, Indiana, upgraded more than 220 of its intersections with advanced signal controller systems and connected them to a central computer system for $5.1 million. The new system, covering a 6.5 square-mile area of the downtown and surrounding intersections, allows traffic signal timing at the cities busiest intersections to be adjusted and synchronized from a remote central control facility. The system allows traffic engineers to quickly modify a.m. and p.m. peak period signal timing strategies, or check operations at a single traffic signal. The computer interface allows engineers to view overall traffic signal operations on an interactive map that superimposed traffic signal activity on an aerial view of downtown Indianapolis.
