How It Works

Traffic calming is the process of physically altering the roadway, such as by installing speed humps or raised crosswalks, in order to force drivers to be more compliant with area speed limits. 

The purpose of traffic calming is to:

  • Increase livability in nieghborhoods
  • Reduce vehicular travel speeds
  • Reduce/eliminate "cut-through" traffic
  • Improve neighborhood and pedestrian safety
  • Utilize a neighborhood-wide approach

Current Traffic Calming Areas


Currently, there are 35 traffic calming areas in the City of Lansing. Generally, the City can evaluate up to three areas per year.

Stop Signs vs. Traffic Calming


Many people wonder why stop signs cannot just be implemented to reduce speeding in areas, but stop signs must be warranted and are based on volume (the amount of traffic on the street) and accidents, not travel speed. Furthermore, in many residential intersections, stop signs are not warranted, making them ineffective. 

Traffic Calming Process


The process of traffic calming begins with collecting data such as traffic volumes (vehicles per day), traffic speeds (85th percentile), existing traffic control, street widths, parking regulations ("no parking," "one-hour parking," etc.), fire routes and accident data. 

Traffic Management Techniques


Prior to implementation of traffic calming, temporary measures can be taken such as police enforcement. Depending on the severity of the issue, residents can request enforcement in their area, however, this is again a temporary service. Another way that temporary traffic calming is implemented is through mobile traffic monitors; these are the electronic machines that reflect the speed limit of cars as they drive passed it.
