B2B Design Standards for Bicycle & Pedestrian Facilities

  • B2B Signage placed every ¼ mile and at every turn (AASHT0 Guide pg. 21)
  • 4-ft. minimum width for bicycle lanes on streets without curbs or gutters (AASHTO Guide pg. 22)
  • 5-ft. minimum width for bicycle lanes on streets with curbs and when adjacent to parking (AASHTO Guide pg. 23)
  • Bicycle lanes should be placed on each side of the street, going with the flow of traffic and, where applicable, placed between the motor vehicle lane and parking lane (bicyclinginfo.org)

    Signage and Traffic Control Devices comply with the Manual on Uniform Traffic Control Devices (MUTCD)

  • 11-ft. minimum width for shared bike lane and parking area (if parking area does not use stripes or stalls) without a curb (AASHTO Guide pg. 22)1
  • 12-ft. minimum width for shared bike lane and parking area with a curb (AASHTO Guide pg. 22)1
  • 6 inch minimum solid white line delineating bike lane from motor vehicle lane (AASHTO Guide pg. 23)
  • 4 inch optional solid white line delineating bike lane from parking spaces, where applicable (AASHTO Guide pg. 23)
  • 10-ft. minimum width for a two-way, shared use path on a separate right of way (AASHTO Guide pg. 35)
  • B2B improvements are necessary anywhere the BLOS (Bicycle Level of Service) is determined to be below a C rating
  • Americans with Disabilities Act guidelines for Accessible Public Rights-of-way included in design elements, including provision of handicap ramps, marked crosswalks and pedestrian signals/pushbuttons.
  • 5-ft. minimum width for sidewalks, excluding curbs and obstructions, recommended by FHWA and Institute of Transportation Engineers on each side of the street (walkinginfo.org)2
  • A buffer of 4-6 feet is desirable to separate pedestrians from motor vehicle lanes (walkinginfo.org)3

    Notes:

    1. Where parking volume is substantial or turnover is high, an additional width of 1-2 feet is desirable
    2. Additional width should be installed in the following areas: near schools, transit stops, downtown areas, and in areas with high pedestrian concentrations
    3. Parking lanes, bicycle lanes, a street furniture zone, and/or a landscape strip are all acceptable buffers
