2.0 2.1 2.2 Figure 1. Snelling A venue is a divided roadway that provides two through lanes, dual left -turn lanes, and a right-turn lane for southbound traffic at County Road B. Northbound traffic uses two through lanes and separate right turn and left turn lanes. County Road B is a four- lane undivided roadway with separate left-turn lanes at each Snelling A venue approach. Frontage roads aceess County Road B approximately 25 feet from Snelling Avenue's east and west approaches. Approximately 400 east of the intersection, County Road B intersects driveways that access Target, Perkins, and other small businesses on the north, and Har Mar mall to the south. Throughout the observations, it could be seen that there was some relation between issues at this intersection and those at Snelling Avenue. However, consistent eonnict observation and accident analysis could not be completed within the existing scope of the project. Occasional observation did lead to limited analysis of this intersection. Analysis of County Road B's intersection with West Snelling Drive and the Burger King driveway, located approximately 400 feet west of Snelling Avenue. was similarly included. Quantitative Intersection Analysis Task 1 - Geometric Analysis A geometric analysis of the intersection was completed to familiarize the observers with the intersection. This included checking for issucs that may be contributing to a high crash risk. These included sight distance, turn radii, horizontal and vertical alignment, signal visibility, signal operation, pavement marking, clear zone, pedestrian and transit facilities, as well as any other relevant geometric features. A list of each of the intersection's deficiencies, including those geometric in nature, can be found in Table I. Task 2 - Historical Volume and Collision Analysis Historical volume data was reviewed to determine trends and peak hours. These volumes showed that during the average weekday, traffic volumes peak during the morning, midday and afternoon peak hours. Due to the absence of average weekend traffic volume data, the intersection was considered to have similar traffic volume patterns to the similarly studied intersection of County Road 42 and Nieollet A venue in the City of Burnsville. The Burnsville intersection is near the retail area of Burnsville Center and has land uses similar to thnse surrounding the intersection in this study. Weekend traffic volume data for County Road 42 and Nicollet A venue indicated a Saturday midday peak comparable to the weekday midday peak hour. Thus, based on the absence of a significant amount of accidents during the morning peak hour at Snelling Avenue and County Road B, a Saturday midday observation was substituted for a weekday morning observation.
