[DRAFT] Intersection Control Evaluation SRF Consulting Group, Inc. County Road E at Snelling Ave N (CR 76) 12 November 30, 2021 Alternatives Assessment Right-of-Way Considerations No additional right-of-way is anticipated to be needed for the all-way stop control or traffic signal alternatives. Based on the concept sketches of a single-lane roundabout, no additional permanent right-of-way is anticipated to be needed, although temporary easements maybe needed for construction. The driveways for the business (Lindey’s Prime Steak House) in the northeast quadrant nearest the intersection will likely require closure under a roundabout design. However, even with a traffic signal or under the existing all-way stop, the driveway is close to the intersection and would be recommended to be closed. Transportation System Considerations Currently, intersections in the immediate study area operate with a mix of traffic signal control and side-street stop control. However, none of the adjacent intersection control dictates the preferred alternative at this intersection. The nearby traffic signal at the TH 51 interchange does cause some platooning into the intersection, which would be better accommodated by a traffic signal or a roundabout. Multimodal Considerations There are existing marked pedestrian crossings across all approaches of the intersection. There are trails in the northwest and southeast quadrants. Another trail is anticipated to go south of the intersection in the near future and another one in the planning stages going to the west. These trail improvements are anticipated to increase pedestrian and bicycle activity through this study intersection. The design of signalized intersections can create a safer environment for pedestrian crossings with the use of pedestrian signal phasing. This phasing allows pedestrians to cross an intersection while adjacent vehicular movements are served. Depending on the signal timing, there can be longer wait times for pedestrians to legally cross with signalized control. The design of a roundabout allows pedestrians to cross one direction of traffic at a time on each leg of the roundabout and recent MnDOT research indicates that roundabouts have improved safety performance for pedestrians compared to signalized control. Local Acceptance All the proposed alternatives are common forms of traffic control in Ramsey County. Roundabouts are the newest form and many of the existing roundabouts are multi-lane or have large radii. The current roundabout concept is a much simpler single-lane and smaller diameter that would fit better into the project constraints.
