[DRAFT] Intersection Control Evaluation County Road E at Snelling Ave N (Old Hwy 10) 1 SRF Consulting Group, Inc. Introduction Ramsey County, in partnership with Arden Hills, is evaluating the County Road E and Snelling Avenue N (CR 76) to improve operations, improve safety, and plan for future needs of the intersections. The intersection currently experiences longer delays and queues when traffic volumes are elevated within the day-to-day fluctuation range (i.e. 10 percent higher than the average). The intersection is planned to be rebuilt in 2023. This report contains the intersection control evaluation (ICE) results for the County Road E and Snelling Avenue N (CR 76) intersection in Arden Hills, Ramsey County, Minnesota (see Figure 1). The MnDOT ICE is a process that identifies the most appropriate intersection control type through a comprehensive analysis and documentation of the technical (safety and traffic operations), economic (societal and agency costs), and other factors of viable alternatives. The goal of an ICE is to select the optimal control for an intersection based on an objective analysis of existing conditions and future needs. The purpose of this evaluation is to analyze various intersection control alternatives under near- term and long-term conditions to identify a preferred intersection control alternative. The following alternatives were considered applicable for this intersection: · All-Way Stop Control (existing) · Traffic Signal Control · Roundabout Control (single-lane) A detailed warrants analysis, operational analysis, and safety analysis was performed to determine a preferred intersection control alternative. In addition to this analysis, other factors considered for this evaluation that were applicable to determining the long-term preferred intersection control included: · Right-of-Way considerations · Construction costs · Transportation System Considerations, including proximity to Bethel College and Mounds View High School (MVHS) · Pedestrian and bike Considerations · Local acceptance.
