Effectiveness Volumes: Depends on the makeup of traffic, number of stop signs, and the available adjacent routes. Stop signs generally do not result in a net reduction of traffic. Speeds: Unlikely to reduce speeds, and depending on the saturation of stop signs, improperly installed signs can often lead to increases in speed between intersections to reduce lost time stopping at the stop sign. (3&10) Safety: If installed in a location that does not warrant a stop sign or where motorists are likely to ignore the sign, the stop sign can lead to an increase in crashes due to driver behavior. (3 & 10) If sight distance is poor due to a permanent installation blocking driver's line of sight, stop signs can have a positive effect on safety. X101 Can add unnecessary delay to the roadway network. Evaluation • Schedule a site inspection to determine if other factors are leading to the issue. (i.e. sight distance, lack of gaps, etc.) • If a lack of gaps is the issue, collect traffic data to determine if stop signs are warranted. • Provide stop/yield sign warrant analysis Reasons to Install • The proposed stop sign will alleviate an existing safety concern. • The intersection traffic volumes meet stop control warrants and are determined to be necessary. Things To Be Aware Of • If a stop sign is installed, there will be an increase in acceleration and deceleration, potentially resulting in noise impacts to the surrounding citizens. �3) • Due to likely low compliance, there could be safety issues. • Adding unnecessary and unwarranted stop signs will likely have a low effectiveness at solving the identified problem. • Additional stop signs can make the intersection feel like it is busier • More signs to maintain Alternative Implementation Options • If speed is the actual issue that is prompting the stop sign request, see the next section for ideas on addressing speeding. • If sightlines are the issue, determine the cause. Things such as trimming bushes or moving a fence post may be effective. • Increase compliance patrols with the police department. • Have neighbors institute a "Neighborhood Speed Watch" program, which may encourage peer pressure to reduce speeds. 110) • Install a yield sign, if appropriate • Installing a stop sign could create a false sense of security Addressing Citizen Requests For Traffic Safety Concerns 15
