Introduction
An advisory bicycle lane, also known as an ABL, is a roadway striping configuration which provides for two-way motor vehicle and non-motorized traffic using a center lane and “advisory” or edge lanes on either side. The center lane is dedicated to, and shared by, motorists traveling in both directions. Vulnerable road users (VRUs), such as cyclists or pedestrians have right-of-way in the edge lanes but motorists can use the edge lanes, after yielding to the VRUs there, to pass other vehicles. This can sound ludicrous to those not familiar with the concept but it works well in numerous countries, including the US and Canada. This roadway configuration originated in the Netherlands where they have over 50 years and many hundreds of road-kilometers of experience with this facility.
While I prefer to use the name "edge lane road" instead of "Advisory Bike Lane", "ABL", or "Advisory Shoulder", this website will use "Advisory Bike Lane" or "ABL" for the foreseeable future.
The video below was produced by the City of Ottawa and is a good explanation of how this type of road operates.

Terminology
Depending on the country and the governing agency, this roadway type can have different names. Examples include: 2-minus-1 roads (New Zealand, Denmark), Edge Lane Road (Denmark), Advisory Shoulders (U.S. Federal Highway Administration), Schutzstreifen (Germany), Suggestiestrook (Netherlands), and Suggestion Lanes (an English translation of the Dutch name, Suggestiestrook).

Purpose
This website has two goals around ABLs: 1) ensure accurate information is available to everybody and 2) put a stake in the ground on design issues with an intent to foster dialogue around those issues. This site targets traffic engineers, bicycle advocates and those that are generally more knowledgeable than average with respect to road design but can be a resource for the layperson as well.
News
The August, 2019 APBP conference in Portland was a success. Tom Bertulis and I presented on ELRs there.
Work within the NCUTCD Bicycle Technical Committee on an MUTCD addition for ABLs continues.
