                Consistent Speed Limits for Vulnerable Road Users – Examples from Various Agencies
**Publication Year:** 
            2020
    
        Background

Speed limits are sometimes inconsistent within a jurisdiction for similar roadways. In some cases, this is because speed limits are applied to roadway sections based on characteristics which may not be obvious to the driver. For instance, speed limits on one roadway classified as a collector are set at 35 mph while another collector with similar characteristics is set at 30 mph due to a higher crash history. Since both appear similar to drivers, they are likely to apply the speed they believe is the most suitable to both roadways.

In other cases, as noted by “Methods and Practices for Setting Speed Limits: An Informational Report,” varying levels of experience, use of different procedures, as well as subjective procedures for determining speed limits can lead to inconsistencies in setting speed limits within or between jurisdictions. In either case, inconsistency violates driver expectancy and can lead to drivers disregarding speed limits.
