The 85% speed is the commonly accepted engineering value indicating the speed at which 85% of drivers fall under and is found to be the speed at which the majority of drivers feel is a safe speed given the roadway conditions and surrounding environment. The 85% speed is also the value typically used to set speed limits and evaluate compliance with speed limits.
Residential roadways with a consistent speeding problem which may be effectively altered with traffic calming device installation typically have greater than 3% of drivers traveling at greater than 10 mph over the speed limit.
Based upon the cumulative results of the neighborhood traffic data, it has been determined that traffic calming device installation is necessary within the neighborhood.
A survey will be performed in February of 2022, in which all properties will be solicited within 600' of a proposed traffic calming devices or whose sole access(es) would be impacted by traffic calming device installation. To move forward with installation, greater than 60% of respondents are required to tally "yes" for the proposal.
This NTS project will propose the installation of two (2) speed tables proposed near the following addresses:
- 4310 92nd ST NE
- 4503 92nd ST NE
