ISSUES FOR EXCESSIVE SPEED LOCATION • Minnesota Manual for Uniform Traffic Control Devices • “Authorized Speed Limit shall be within 5 MPH of the 85th Percentile Speed” • Functional Classification of the Roadway • Residential Street will receive the full range of Traffic Calming Devices, some of these are not appropriate for Arterial or Collector Streets.
