Residents requesting neighborhood traffic calming are required to submit a traffic study request form which includes a ten-signature petition from neighbors supporting the request for a traffic study.
Neighborhood Traffic Study
Upon submission of the Neighborhood Traffic Study Request form with the required signatures, the Transportation Division will conduct a traffic study. Traffic data is collected for one week. An 85th percentile speed and daily traffic volume is measured.
Studies are completed between April and October.
Only one study request per year may be submitted for a specific street or area.
Traffic Study Criteria
The following criteria are used to develop a Neighborhood Traffic Calming Index:
Speed and Volume Criteria
Speed Points (10 pts for every 1 mph over the posted speed limit)
Traffic Volume (1/2 pt per 100 vehicles)
Other Criteria (10 Points Max)
Sidewalks (5 pts if no sidewalk)
Elementary Schools (5 pts for each elementary school or road is on a school walking route)
Pedestrian Generators (5 pts for each park, Jr. high, high school, etc...)
The traffic study criteria are summed to determine the Neighborhood Traffic Calming Index and action is taken based on the Index as follows:
Index less than 70: No Action
Index between 70–79: Driver Feedback Signs
Index 80 or greater: Physical constructed calming device (normally speed humps)
If a road meets the criteria for physical constructed traffic calming, the residents living on that road will be polled, if two-thirds of responses are affirmative, traffic calming construction will be scheduled.
Roads with a speed limit higher than 25 mph are not eligible for speed humps.
