Traffic Control Requests | City of Plymouth, MN

The City of Plymouth receives a significant number of requests for traffic control signage each year – many from residents who wish to slow the speed of motorists driving through their neighborhood. View information about submitting a request below.

Are stop signs effective for speed control?

The city often receives requests for the installation of stop signs to reduce speeds on residential roadways.

Are stop signs effective for speed control?
According to the Minnesota Local Road Research Board, stop signs are meant to assign right-of-way to motorists to prevent crashes – but stop signs are not an effective tool for speed control.

Studies have shown that when stop signs are used inappropriately, motorists may intentionally violate stop signs and increase their speed between stop signs to make up lost time from what they perceive as an unreasonable stop.

Are additional speed limit signs effective?

The City of Plymouth frequently receives requests to post speed limit signage in residential areas to influence motorists to slow down. However, all residential roadways in Minnesota have a speed limit of 30 mph, as mandated by the state.

Are additional speed limit signs effective in reducing speeding in residential areas?
Studies show there is little change in speed patterns after additional speed limit signs are posted, nor is it effective to reduce the speed limits on residential roadways. According to the Minnesota Local Road Research Board, motorists are influenced by the conditions of the road and will drive a speed at which they feel comfortable.

Roundabout Resources

What's a Roundabout?

A roundabout is a circular intersection designed to let vehicles go through more safely and in less time. Roundabouts also help simplify crossings for pedestrians and bicyclists.

According to the Minnesota Department of Transportation, roundabouts show an 86% decrease in fatal crashes, an 83% decrease in life-altering injury crashes and a 42% overall decrease in the injury crash rate at intersections. In addition to reducing the severity of crashes at intersections, roundabouts handle high levels of traffic with less delay than most stop signs or signals.
