Advisory Shoulders & Bike Lanes: Multiple Locations

Transportation
Upcoming
PBOT has installed advisory shoulders or bike lanes in three locations in Portland in 2022. Advisory shoulders and bike lanes are a low-cost, low-impact treatment for narrow streets with lower volumes of traffic and speeds.
When using an advisory bike lane, drivers from both directions use the center lane. Drivers move into bike lanes to pass each other safely.
Construction in 2022 and 2023

What's happening now?

Advisory shoulders and bike lanes are complete for the 2022 construction season. The easternmost section of NE San Rafael Street will not have advisory lanes installed until further evaluation takes place.

  • NE San Rafael Street between 132nd and 148th avenues is on hold while the project team evaluates advisory shoulders and bike lanes in other parts of the city.
  • NE San Rafael Street between 122nd and 132nd avenues does NOT have advisory bike lanes. The section between 122nd and 132nd avenues has two standard width travel lanes, two buffered bike lanes, and one parking lane on the north side of the street. 
  • Read the project notification and update from October 20, 2022.
  • Community meeting with the Russell Neighborhood on Thursday, 10/6/22. Here is the presentation from the Russell meeting.

Advisory shoulders and bike lanes have been installed in three locations in Portland in summer and fall, 2022: 

  • NE San Rafael Street between 111th and 122nd avenues as part of the resurfacing project.
  • NE 43rd Ave between NE Tillamook St and NE Sandy Blvd on the Tillamook Neighborhood Greenway
  • NE 53rd Ave between NE Hoyt St to NE Irving St on the 50s Bikeway

How do advisory shoulders and bike lanes work?


Project background and description

View a one-page hand-out about PBOT's plans for advisory bike lanes in Portland

PBOT will monitor and evaluate the advisory bike lanes after installation. The installation uses low-cost, non-permanent materials to allow for modifications as needed. 


Why advisory shoulders and bike lanes?

  • On shared roads, they provide space for people walking and using mobility devices where sidewalks don't exist.
  • The design provides more space between people biking, walking, and rolling and people driving.
  • They limit the likelihood of a bicyclist being hit by a parked car’s opening door, while still allowing for on-street parking.
  • They’re a great treatment for narrow streets with low vehicle traffic and low speeds.

What do we know about advisory shoulders and bike lane safety?

  • Studies from 11 US cities over 8 years and 60 million vehicle trips showed a 44% overall reduction in crashes compared to previously existing 2-lane configurations. (Mineta Institute. Safety Considerations for All Road Users on Edge Lane Roads. 2022)
  • Friction on the road typically leads to vehicles operating more carefully and at safer speeds.
  • PBOT will only install advisory bike lanes on streets with low motor vehicle traffic and low speeds.

Frequently Asked Questions

What qualifies as a "low traffic street" for advisory shoulders or bike lanes?

Federal Highway Administration guidance recommends streets that average less than 4,000 vehicles per day. PBOT's constructed or proposed advisory shoulder and bike lane project streets all operate with less than 4,000 vehicles per day, with most in the 1,500 to 3,000 average daily traffic range. The last 10 years of collected traffic data is available on our publicly accessible webmap.

What traffic studies have you done on the existing or proposed projects? 

Each project will have before and after traffic impact analysis completed. Those studies include collecting and interpreting vehicle speeds and volume data, evaluating crashes and crash risk, and conducting transportation network analysis for potential benefits and issues that could arise.

For example, PBOT has conducted 81 traffic counts (and 34 since 2015) on NE San Rafael Street between NE 111th and NE 148th Avenues. Depending on the street's operating conditions and the length of the proposed project, the number of traffic studies will vary.

Will advisory lanes or shoulders lead to more crashes?

In other cities, the advisory lane design led to equal or lower speeds, and equal or reduced crash rates. The Mineta report (2021) studied 13 US advisory lane sites and estimated a reduction in crashes of 7 – 44%, with zero head-on crashes.​ The Alta report (2017) studied 10 advisory lane sites in US/Canada. No significant issue with crashes has been reported in any installation. Some reported improvement.​ PBOT intends to post each advisory shoulder or lane at 20 mph.​

Why build advisory lanes or shoulders where there are few people biking?

Portland city goals call for creating conditions that encourage and allow for increased pedestrian, bicycle, and transit use as alternatives to driving. PBOT experience has been that creating good conditions for biking results in more biking and less driving. PBOT understands that not everybody is going to ride a bike. Even those who do ride bikes don't do so for every trip. All of our advisory shoulder or bike lane designs continue to accommodate two-way traffic for automobiles. These projects improve mobility for more people and modes of traffic.

Why not build sidewalks instead of advisory shoulders or protected bike lanes instead of advisory bike lanes?

PBOT's goals are to build to sidewalks and better bike lanes on many miles of city streets. However, many of those streets require significant financial investments to build new sidewalks or protected bike lanes. In the meantime, advisory lanes and shoulders can provide increased mobility and better spaces for walking, biking, and rolling.

What if two cars collide, who will be at fault?  

Traffic is expected to yield to oncoming traffic, This website has more information from the Oregon Revised Statutes (oregon.public.law/statutes/ors_811.300). If you have specific questions around the law, it is best to contact legal consultants.

Do advisory lanes violate the Oregon law that prohibits driving in bicycle lanes (ORS 811.440)?

ORS 811.300 addresses the need for drivers to move right for oncoming traffic. The duty of care that all drivers must take in ensuring that there are not cyclists in the bike lane before entering into that bike lane, assuming they needed to avoid oncoming vehicular traffic, would also apply. These are concomitant duties; they are not necessarily exclusive of one another. This specific design is consistent with advisory bike lane design in the US, Canada, and other parts of the world, and approved by the Federal Highway Administration. PBOT has no indication that the design will increase the risk of crashes, with published research concluding it typically reduces crash risk. If you have specific questions around the law, it is best to contact legal consultants.
