6.3A ATTACNMENTPagg CITY OF REDWOOD CITY POLICY AND GUIDELINES FOR STOP SIGNS ON RESIDENTIAL STREETS Description: A regulatory sign placed at intersections. It requires drivers to come to a complete stop and assure that it is safe under the normal right of way rules before proceeding. Objective: Control of right of way at intersections where there is reason to believe that the intersection does or would not operate within reasonable safety expectations if left to operate as an uncontrolled intersection under the general right of way law. Often this is because of factors which obstruct sight distance for vehicles entering the intersection from conflicting approaches. Neighborhood Traffic Applications: Residents often desire STOP signs as a remedy for perceived collision or pedestrian crossing dangers, as a traffic diversion device, or for speed control. Requests for neighborhood applications frequently become controversial for two reasons. First, traffic engineering practice normally requires objective evidence of need for right of way control, rather than just the perception of danger. Second, the use of STOP signs for diversion or speed control is contrary to traffic engineering evidence and opinion, which argues such STOP applications are ineffective for those purposes. Prerequisites,Limitations & Constraints: Warrants for STOP signs defined in the California Department of Transportation Traffic Manual are followed at all intersections on streets designated arterials and major collectors. These warrants are incorporated into this document by reference. Numerous California communities have found that the warrants in the Traffic Manual tend to emphasize the traffic flow function of arterial and major collector streets,and are unresponsive to needs on residential streets. The following warrants,patterned after ones in use in other Bay Area communities, are to be used in evaluating appropriateness of STOP signs at residential intersections of local access streets or minor collectors with other local access streets. All-way stop sign installations may be considered on minor residential collectors and local streets where residents of 10 or more nearby dwelling units have signed and submitted a written request. Warrants for installation of all-way stop signs on residential collectors or minor residential streets are satisfied if both of the following conditions exist at an intersection: A. The total volume on the major (busier) street approaches is at least 1,000 vehicles per day, but not more than 4,000, and the total volume on the minor street approaches is at least 900 vehicles per day,and at least one of the following conditions exist: 1. When 20 or more elementary school children use the intersection going to or from a school or park during an hour when at least 300 vehicles (total from all approaches passing through the crosswalk)are in direct conflict with pedestrians; 2. When 20 or more elementary school children use the intersection going to or from a school or park during an hour when the 85th percentile speed is at least 10 mph higher than the posted speed limit,and lower speeds at the intersection are necessary for pedestrian protection (speed measured at or very near the intersection, on the street crossed by pedestrians);
