City of Arden Hills – 2040 Comprehensive Plan Approved: XXXXX B-17 3.1 ROADWAY WIDTH Roadway and travel lane widths are directly associated with a roadway’s ability to carry vehicular traffic. On Major Collector roadways and Minor Collector streets, a 12’ lane is recommended for each direction of travel. The 24’ total travel width is recommended to accommodate anticipated two-way traffic volumes. In addition to the travel width, a minimum 6’ shoulder lane width accommodates pedestrian and bicycle traffic, parked or stalled vehicles, and maintenance activity. Roadway widths not meeting the Geometric Design Standards results in decreased performance of the particular roadway and additional travel demand on the adjacent roadway network components. For example, a sub-standard Major Collector roadway may result in additional travel demand on an adjacent Minor Collector or local street, resulting in an overburden for adjacent landowners. Similarly, additional local circulation on an adjacent Minor Arterial results in reduced mobility for regional trips. Due to the varying right-of-way widths present in Arden Hills, Figure B.5A and B.5B identify four different typical sections for Minor Collector roadways to be considered as reconstruction is pursued. 3.2 PATHWAYS Pathways, including bikeways, sidewalks, trails, and some roadway shoulders, are recommended to be on or adjacent to Major Collector and Minor Arterial roadways, and most Minor Collector roadways to accommodate pedestrian, bicycle, and other non- motorized travel in a safe and comfortable manner. These roadways carry a considerable amount of vehicular traffic and non-motorized facilities are recommended. Design and accommodations for non-motorized traffic facilities in Arden Hills follow the MnDOT Bikeway Facility Design Manual; Americans’ with Disabilities Act (ADA); AASHTO Guide for the Planning, Design, and Operation of Pedestrian Facilities; FHWA Designing Sidewalks and Trails, Part II, Best Practices Design Guide; and FHWA Design Guidance, Accommodating Bicycle and Pedestrian Travel: A Recommended Approach. The City will continue to work with Ramsey County and MnDOT to plan, evaluate, and design non-motorized facilities and integrate the facilities into reconstruction efforts. At the discretion of the City, the requirements for trails, sidewalks, bikeways, and shoulders may vary. The non-motorized traffic facilities will provide connectivity as shown in the Arden Hills Parks, Trails, and Open Space Plan. 3.3 DESIGN SPEED The design speed of a roadway is directly related to the roadway’s function in the roadway system. The focus of Minor Arterial roadways is mobility; therefore these roadways should be designed to accommodate higher travel speeds. Likewise, Minor Collector roadways are more focused on accessibility and should be designed to Dr a f t 11 / 2 0 / 2 0 1 7
