Evaluation of a Combined Bicycle Lane/Right Turn Lane in Eugene, Oregon

Federal Highway Administration



In many bike-lane retrofit projects, there is not enough space to mark a minimum 1.2-m bike lane to the left of the right-turn lane. This report focuses on a combined bicycle lane/right-turn lane used when right-of-way at an intersection is limited. This evaluation took place in Eugene, OR.

The narrow right-turn lane described above was evaluated by comparing the behaviors of bicyclists and motor vehicle drivers at an intersection that had the shared, narrow right-turn lane described above in place with behaviors at an intersection that had a standard-width (3.7-m) right-turn lane and accompanying bike lane (pocket) to the left of the right-turn lane.

Bicyclists traveling through each intersection were videotaped. The videotapes were coded to evaluate operational behaviors and conflicts with motorists, other bicyclists, and pedestrians.
