Design Cyclist • Novice • Children • Varying levels of ability and judgment • Speeds + lack of judgment Image source: FHWA Course on Bicycle and Pedestrian Transportation

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
