The goal of Iowa City’s Neighborhood Traffic Calming Program is to reduce excessive speeding and/or traffic volumes on streets. Participation in the program is neighborhood-initiated and is not imposed by the City. To find out more about the traffic calming program, review the traffic calming brochure.
Below is a list of current traffic calming projects happening in Iowa City.
Current phase: pilot program
The City will install two radar feedback signs along 7th Avenue between Glendale Road and Court Street, one for northbound traffic and one for southbound traffic.
The signs display the driver's speed and caution them to slow if they are speeding. Research indicates that feedback signs may be effective at lowering speeds, especially among drivers exceeding the speed limit by 10 MPH or more.
Staff will re-evaluate speeds 6 and 12 months after installation to measure their effect on speeds. Staff recommend that signs be removed if they do not produce a substantial sustained reduction in speeds or if maintenance and reliability becomes an issue.
No additional installations of radar feedback signs will be considered elsewhere until after the end of the 12-month study period is complete.
Current phase: construction Spring 2018
The residents of Friendship Street, between Court Street and Brookside Drive, have successfully completed the City of Iowa City’s Traffic Calming Program.
A traffic study determined that the street qualifies for the program based on traffic speeds. Staff discussed the proposal with residents at a neighborhood meeting. A follow-up survey of neighbors yielded an 81 percent response rate. Of those households that responded, 78 percent indicated their approval of the proposal to install speed humps.
Speed humps will be installed at four locations along Friendship Street and spaced to allow drivers to travel at a consistent speed of 20-25 MPH. Signs will be posted and speed humps are painted to make drivers aware of their location.
