Learn about the design of bicycle facilities to accommodate cyclists with varying levels of ability and judgment, including novices and recreational riders. Explore different types of facilities, such as paved shoulders, wide lanes, and bike lanes, and understand the design considerations at intersections. This course references federal, national, and state policies and standards for designing bicycle facilities.

Designing bicycle facilities: Policies and Standards • Federal/National: • U.S. Access Board: Americans with Disabilities Act Accessibility Guidelines • FHWA: Manual on Uniform Traffic Control Devices (MUTCD) • AASHTO: Guide for the Development of Bicycle Facilities • State and Local Manuals • Example: Oregon DOT Bicycle and Pedestrian Plan FHWA Course on Bicycle and Pedestrian Transportation
Paved Shoulders • any additional width is better than none • If < 4 feet, cannot designate or mark as bicycle lane • Minimum 4 feet width to be marked as bicycle facility • Must be usable Bike Lane Design Guide and www.bicylinginfo.org
Paved Shoulders • > = 5 feet with guardrail, curb, or other barrier • Increase with higher bicycle usage or higher vehicle Bike Lane Design Guide and www.bicylinginfo.org
Wide Vehicle Travel Lanes • bicycle lane is best but wide travel lane is better than nothing • Allows motorist to safely pass cyclists while remaining in the same lane • 14 feet recommended for outside lane measured from edge line or joint of gutter pan to lane line

Wide Vehicle Travel Lanes • 15 feet preferred when extra space to maneuver is required • Steep slope • On-street parking Image source: King et al, 2002
Wide Vehicle Travel Lanes • 15 feet preferred when extra space to maneuver is required • Steep slope • On-street parking • Avoid lanes that are too wide, vehicles treat as two lanes • Consider creating separate bike lane
Bike Lanes • Portion of roadway designated by striping, signing, and pavement marking for preferential or exclusive use by bicyclists King et al, 2002
Bike Lanes • 4 feet minimum with no curb and gutter • 5 feet min. adjacent to parking, next to gutter, or guardrail • 11 feet shared bike lane and parking area with no curb face • 12 feet shared bike lane and parking area with curb face
Bike Lanes • Lane stripe • 6 inch solid white separates from vehicle lane • 4 inch optional to separate from parking spaces
Bike Lane • Use only by bicyclists • Bicyclists are expected to make left turn from left turn lane and not bike lane • Why not sidewalks • Motorists are not looking for fast moving vehicles on sidewalk • Have same rights as motorist • Conflicts with pedestrian • ??? Bike Lane Design Guide. 2002.

Intersections • The recommended designs are based on the assumption that: • motorists making right turns should make their turn from as close to the right-hand curb as practicable • bicyclists going straight ahead should be to the left of right turning traffic • bicyclists turning left should turn from a left turn lane or left side lane Bike lane design guide, 2002
Bike lane at uncontrolled intersection: bike lane stripes should not be extended through a pedestrian crosswalk or any street intersection (with the exception of dashed lines through some complex intersections)Bike lane at controlled intersection: bike lane stripe ends at stop line or crosswalk with right turning traffic bike lane dashed for final 50ft-200ft (15m-60m) with bus stop bike lane dashed for length of bus stop • Bike lane at intersection w/right turn lane: see diagram (on p. 29 of the AASHTO Guide for the Development of Bicycle Facilities, 3rd Edition) www.bicylinginfo.org
Bike lane at intersection w/left turn lane: optional bike lane stripe to right of left turning vehiclesBike lane at modern roundabout: discontinue lane 35-65 feet (10m-20m) prior to low speed roundaboutBike lane at multi-lane roundabout: discontinue lane prior to roundabout; consider separated bikeway, shared use of sidewalks, grade separation or re-routing (none are especially good options)Bike lane at high speed interchange: see diagram (on p. 63 of the AASHTO Guide for the Development of Bicycle Facilities, 3rd Edition) www.bicylinginfo.org
