Abstract
Traffic signal locations in Broward County, Florida.
Purpose
This coverage was created in 1994 to be used in traffic analyses of the Broward County Congestion Management System. In addition to its use in the Congestion Management System analyses, maps of the traffic signals have been prepared in response to general public's requests.
Maps of the traffic signals are also used by the County's staff including signal design engineers and transportation engineers/planners.
Supplementary Information
Full-color signals only. Does not include fire house signals, preempters, post or span beacons, U-turn signals, and pedestrian signals.
