Real-time traffic information - East Washington Ave.
Traffic condition cameras and dynamic message signs are being
used along Madison's East Washington Avenue to ease congestion and
disseminate travel information during construction. The equipment
will continue serving the corridor after construction is complete in
This traffic management and travel information project is the
first step in reconstructing the busy thoroughfare, which on average
carries at least 39,000 vehicles a day. Reconstruction started in
spring 2004, with the first phase of work taking place between Blair
Street and Thornton Avenue.
As well as helping travelers, the electronic signs and cameras
provide important information to traffic engineers and the Dane
County 911 Center. Dispatchers are able to use the signs to alert
drivers of crashes or other hazards. They are also able to direct
emergency vehicles around traffic jams, preventing delays in
Specific elements of the project include:
Five dynamic message signs stationed along the avenue and
other major streets that feed into the corridor.
Five cameras to supply data to traffic engineers and public
Wireless controls for key traffic signals to prevent
disruption during construction.
The system encourages the continued use of East Washington Avenue
during construction by maximizing green lights and controlling turn
movements in order to limit traffic through local neighborhoods. The
traffic management equipment also maintains access to local
businesses and pedestrian-friendly crosswalks.
The electronic signs will be placed between the sidewalk and curb
and will be slightly taller than electronic signs seen at other
construction sites. The system is consistent with the public's
desire to have a community sensitive design with aesthetic signal
and camera poles and sign structures.
