Are signals in downtown St. Charles synchronized and have improvements been made to them?
The downtown signals are synchronized. The City worked with the Illinois Department of Transportation (IDOT) in 2002 on a computer model of traffic signal operations using traffic count data observed in the field. This simulation identified discrepancies in the coordination between signals along IL 64 (Main Street) between 7th Ave. and 7th St. The computer software also modeled ways to optimize signal coordination. The updated traffic signal synchronization along IL 64 was installed in 2003 and also coordinates with the Illinois corridor just two blocks south. Since 2003, City staff have been monitoring downtown traffic signal performance weekly and promptly addressing signal malfunctions.
