what the correct intersection control should be; however, the following factors should be evaluated when determining intersection control. Traffic Conditions: The traffic conditions of an intersection include: • Traffic approach volume • Speed of traffic approaching the intersection • Number of turning vehicles in an intersection • Vehicle makeup (i.e. trucks, buses, etc.) • Crash history in the intersection Topographic Conditions: The topographic conditions of the intersections are the physical features in the area, including: • The grade of each approaching roadway • Location and size of adjacent buildings or structures • Angle of the intersection • Geometrics (number of lanes) of the intersection • If a school, park or major pedestrian generator is located in the area Based on these conditions and factors, potential intersection control should be evaluated and determined. Several techniques have been developed to determine what type of intersection control is warranted at a specific location. Policies for two-way and all-way stop sign installation are discussed below. Intersection Control Policies: When developing policies for two-way and all-way stop sign controlled intersections, the traffic conditions and topographic conditions can be used quite readily in the analysis procedure. Additional, non-technical factors may also be considered during the analysis procedure. Therefore, engineering judgment should be utilized when evaluating the appropriate intersection control. Analysis Procedure: The best procedure in evaluating the need and location of two-way or all-way stop sign control can be found in the Minnesota Manual on Uniform Traffic Control Devices (MnMUTCD), Section 2B-5 and 2B-7. Based on those warrants, the following two-way and all-way stop sign installation procedures should be followed: Step 1: Request for intersection control evaluation This request can come from either a resident, the City Council, the Traffic Safety Committee, or from staff observation of a particular intersection. If a request is made from a resident, a signed petition of more than 80% of the households within a 300' radius of the intersection, must accompany the request. Step 2: Data collection This step in the procedure involves collecting the data necessary to evaluate the proposed intersection control. The data required for each phase is listed below.
