City of Arden Hills – 2040 Comprehensive Plan Approved: XXXXX B-8 Each access location (i.e. driveway and/or intersection) creates a potential point of conflict between vehicles moving through an area and vehicles entering and exiting the roadway. These conflicts can result from the slowing effects of merging and weaving that takes place as vehicles accelerate from a stop turning onto the roadway, or deceleration to make a turn to leave the roadway. At signalized intersections, the potential for conflicts between vehicles is increased, because through-vehicles are required to stop at the signals. If the amount of traffic moving through an area on the roadway is high and/or the speed of traffic on the roadway is high, the number and nature of vehicle conflicts are also increased. Accordingly, the safe speed of a road, the ability to move traffic on that road, and safe access to cross streets and properties adjacent to the roadway all diminish as the number of access points increases along a specific segment of roadway. Because of these effects, there must be a balance between the level of access provided and the desired function of the roadway. In Arden Hills, access standards and spacing guidelines are recommended as a strategy to effectively manage existing ingress/egress onto streets and to provide access controls for new development and redevelopment. While the City of Arden Hills has access authority for those roadways under its jurisdiction, Ramsey County and the Minnesota Department of Transportation (MnDOT) have access authority for roadways under their jurisdiction. The permitted width of accesses to County or State streets or roads is subject to County or State regulations. The State regulations for access standards and spacing are included in the MnDOT State-Aid design standards and the MnDOT Access Category System and Spacing Guidelines (referenced in Table B.3 and B.4).
