Evaluation • Schedule a site inspection to review the issue with the citizen. • Review crash history, roadway geometry, and land use within the area. • Perform speed data collection via road tubes or radar detection (i.e. speed trailer/board) to determine what the speeds are. Identify the, average speed, 85th percentile speed, and 10 mph pace. Reasons to Install • If the collected speed information indicates drivers are driving the roadway at a different speed than that is set, a speed limit change can be submitted to the commissioners office for review. Note, this sometimes results in a speed increase rather than decrease. Things To Be Aware Of • Speed related complaints are typically identified by someone's perception of a vehicle speeding, not an actual speed issue. • Speeding issues where the request it to install speed table/speed humps are larger scale issues involving much more time and money to evaluate. Also, speeds tend to only be affected near the humps, not necessarily in between. • A change in speed limits likely have a low effectiveness at solving the identified concern. • Speed limits within neighborhoods are likely already at the minimum based on state law. • Often citizens request for a sign to be installed in residential areas that reflects the unposted statutory speed limit. However, posting speed limits advertises that a given speed is acceptable even though it is desired that drivers drive slower. • Roadway narrowing to reduce speeds can be effective, but can be an expensive measure. 121 • Often the speed offenders are people that live in the neighborhood. (12) 18 DECEMBER 2017 1 LOCAL ROAD RESEARCH BOARD Alternative Implementation Options • Meet with the citizen and identify vehicle speeds using a radar gun to determine if it is only a perception, not an issue. • Encourage the citizen to talk with their neighbors in person, as they are typically the offenders. (12) Use a community event such as "Night to Unite" to have the discussion. Avoid using social media. • If speed is the key issue, install a temporary speed trailer to monitor traffic speeds, speed trailers can bring attention to drivers that their speeds are too high. • Install temporary yard signs ( similar to political signs i.e, drive like your children live here), green children signs/figures or toys in yard when children are playing. It is key to put these items away when children are not present. Be sure to consider right-of-way impacts when putting up signs (i.e. if on shoulder of a roadway) • Citizens can help their cause by parking on street (can help reduce speeds) • Increase compliance patrols with the police department.
