[DRAFT] Intersection Control Evaluation SRF Consulting Group, Inc. County Road E at Snelling Ave N (CR 76) 13 November 30, 2021 Conclusions and Recommendations The following intersection control evaluation (ICE) conclusions and recommendations are provided for the County Road E and Snelling Avenue N intersection in Arden Hills, Ramsey County, Minnesota: · Warrants Analysis The results of the signal warrant analysis indicate that Warrant 1A, Warrant 2, Warrant 3B, and the all-way stop warrant are expected to be met under Opening Year 2023 conditions and continue to be met under Forecast Year 2043 volumes, along with Warrant 1C. A signal or all-way stop being warranted is also justification that a roundabout is “warranted.” · Operations Analysis Results of the operational analysis indicate that the all-way stop control alternative is expected to perform at an overall LOS D with a worst approach at LOS F during the p.m. peak hour under Forecast Year 2043 traffic volumes and existing lane configurations. The traffic signal alternative is expected to perform at an overall LOS B during the a.m. and p.m. peak hours, and the roundabout is expected to perform at overall LOS A under Forecast Year 2043 traffic volumes and proposed lane configurations. Bethel College and Mounds View High School (MVHS) are in the vicinity of the study intersection, which can result in sharp traffic peaks due to the release of students. The all-way stop control alternative does not accommodate these peaks in traffic volumes as well as a traffic signal or roundabout would. · Safety Analysis Based on the results of the crash analysis, all three alternatives are anticipated to have a similar number of crashes per year. Although, serious injury and fatal crashes are not currently a concern at the study intersection based on observed crashes, roundabout control is likely to have the fewest number of serious injury and fatal crashes per year based on the speeds and angles of the conflicts. · Planning-Level Cost Analysis A traffic signal or roundabout would require capital costs to construct. Traffic signals typically have higher operation and maintenance costs because of the electricity required to operate the signal and routine maintenance required to keep the signal in operation. Operation and maintenance costs associated with a roundabout can vary depending on the amount of illumination required or landscaping alternatives used for the center island. A roundabout is anticipated have a higher construction cost ranging between $1,200,000 and $1,500,00 compared to $300,000 and $400,000 for a traffic signal. · Right-of-Way Considerations The roundabout control, as currently designed, is not expected to require additional right-of-way, and may only require temporary easements during the construction phase. A traffic signal is also anticipated to not require additional right-of-way. The existing business in the northeast quadrant
