Best Practices in Implementing Tactical Transit Lanes

Wednesday, April 3, 2019 - 17:30

This guide, intended for planners interested in improving transit service where traffic congestion constrains its quality, introduces a category of project called the “Tactical Transit Lane” (TTL). These are bus-only lanes installed in congested, dense areas along specific segments where operational data indicate transit vehicle delays and schedule variability are significant and affecting a large number of riders. This tactical use of bus only lanes, installed only where and when they can provide rider benefits, is a recent phenomenon: all 17 of the TTLs found in metropolitan areas across the country were implemented after 2013 (and most after 2016) either permanently or as pilot projects, which TTLs’ low cost and reversibility make feasible.
