City of Dubuque steers the future of traffic safety towards IP technology
“The system gives me a really good heartbeat on the city. We can go back through the footage to see what led up to accidents and get a good feel for what might help [in the future].” David Ness, professional engineer for the City of Dubuque.
The City of Dubuque, Iowa, is a regional hub of 60,000 people on the border of Illinois and Wisconsin. In the early 2000s, the traffic department began linking traffic signals and intersections together in a fiber optic network. Initially, they installed network cameras to detect vehicles at the intersections for signal changes, but they later switched over to microwave-based detectors. Unfortunately, with the change, they lost the ability to view and record video at the intersections.
To reestablish visual support, the traffic department selected a mix of Axis network cameras provided by systems integrator and Axis partner RACOM Corp. They first installed fixed HDTV AXIS Q1755 Network Cameras, as well as HDTV 1080p AXIS Q6035 pan/tilt/zoom (PTZ) for targeted examination. Then, when Axis released the fixed AXIS Q1604 Network Camera with Wide Dynamic Range-Dynamic Capture, the city saw how well wide dynamic range could combat the effects of direct sunlight, reflections off passing vehicles and glare from nearby lights. AXIS Q1604 cameras soon became the standard for future installations. Milestone XProtect® Video Management Software provides critical support for viewing and extracting video at city hall.
The IP cameras have become an integral component of the city’s Intelligent Transportation System. Video analysis helps traffic engineers improve roadways without incurring the high costs of new construction. They are able to update signage and roadway markings to improve traffic safety. Police use footage to get an accurate account of accidents and other incidents. ocal citizens also use the video to settle disputes over accidents without the need to go to court.
