Traffic Island - Muirfield Road

Traffic Circle - South Shore at Emerald

Neighborhood Traffic Management Program provides a mechanism for City of Madison alderpersons, neighborhood groups and representatives to work with City staff to make decisions about traffic management in their neighborhood.

The Neighborhood Traffic Management Program is a response to community concerns about traffic in neighborhoods such as:

  1. speeding.
  2. excessive traffic on local streets
  3. drivers not being courteous to pedestrians.
  4. traffic safety around schools including drivers not slowing down in school zones and parent drop-off/pick-up safety issues.

Neighborhood associations or groups, Alderpersons representing a neighborhood and neighborhood business associations are eligible for participation in NTMP.

Individuals are encouraged to work with or form a working group of residents in their area of concern.

  1. Traffic signs rely on driver cooperation and adherence to laws related to the signs.
  2. Police enforcement is typically needed to ensure effectiveness of signs.

The advantages of physically changing the street over simply installing traffic signs include:

  1. Police enforcement is generally not required to achieve lower speeds.
  2. Removal of excess pavement width in some areas.
  3. Eliminates straight appearance of the roadway.
  4. Vertically deflect and horizontally shift the vehicle driver's path, causing the driver to devote more attention to the task of driving.
  5. Visually enhances the street by adding greenery.

Traffic calming is the combination of mainly physical measures that reduce the:

Pedestrian islands have also been installed on Muir Field Road between Elder Place at Rosa Road and at Bordner Drive.

In most cases on local streets, traffic islands will require the prohibition of parking at all times along the street curb the full length of the narrowed section plus approximately 40 feet.

Speed Humps are a rounded raised area of pavement, placed at mid-block on residential streets classified as local by Madison Department of Transportation. These are the most common traffic calming devices in the United States. They are effective speed control devices and are not like the speed bumps you may have encountered in private parking lots.

Speed Humps are often placed in series. The speed humps on S. Shore Drive were placed as part of the NTMP. Speed humps have also been installed on South Shore Drive, Fisher Street and Yuma Drive.

Speed humps are generally installed on streets where the posted or prima facie speed limit is 25 mph or less and volume of vehicles does not exceed 3000 vehicles per day. They are used on streets with no more than two travel lanes and less than or equal to 32 feet in width.

Speed hump heights range between 3 to 3.5 inches.

Speeds between humps have been observed to be reduced between 20 and 25% on average.

Studies indicate that traffic volumes have been reduced on average by 18% depending on alternative routes available.

Traffic circles are circles of varying diameter formed by curbs. The curbs are partially or wholly mountable to enable large vehicles to turn around the circle.

Madison's first neighborhood scale traffic circle was installed in 1997 at the intersection of Kendall and Grand Avenues (left).

Traffic circles have been installed at New Washburn Way/, Dandaneau Trail/Chautauqua Trail and Glenway Street/Hillcrest Drive intersections.

Traffic circles slow down traffic by forcing drivers to slow to a speed that allows them to comfortably maneuver around them.

Please see the guide for safe driving around a traffic circle.

Traffic circles have been reported to reduce midblock speed by about 10%.

Reduction in intersection collisions on average by 70% and overall collisions by 28%.

  1. Continuous involvement of the neighborhood residents.
  2. Emergency services must not be seriously impaired.
  3. Build attractive devices.
  4. Traffic diversion to other streets must be minimized.
