Green Bike Lanes

Flagstaff Welcomes Green Bike Lanes

What are they?

Green Bike Lanes are colored pavement markings placed through an intersection, acting as a supplement to the white dashed bike lane extensions. The purpose of the Green Bike Lane is to draw the attention of the motorist to the bicyclist, in turn, avoiding vehicle/bicycle collisions in high conflict areas.

Where are they located?

The locations of the Green Bike Lanes were chosen due to the high amounts of crash volumes between motorists and bicyclists. The Green Bike Lanes have been installed at various intersections along Beaver St.; Phoenix Ave., Cottage Ave., Butler Ave., and Dupont Ave. See the pictures above and the map below.

Why are they being utilized in Flagstaff?

Green Bike Lanes have been placed at various locations throughout Flagstaff as an experiment for the Northern Arizona University’s traffics department. The City of Flagstaff has agreed with the university’s staff to supply the materials and labor for this project. The university’s staff will record the interaction of motorist and bicyclist before and after the installation of the Green Bike Lanes. A video camera will capture approximately 90 hours worth of data from the three intersections. This information will be used by the university to conduct research on the topic, while teaching students how to analyze data from a practical experiment.

How are they used?

When a motorist needs to turn across the Green Bike Lane, they need to ensure there are no bicycles approaching. If there is a bicycle approaching, the motorist needs to attempt to make eye contact and yield to the bicyclist. The driver needs to make sure they fully turn and check blind spots.

When a bicyclist is approaching an intersection with the Green Bike Lane application, they need to be cautious and attempt to make eye contact with the motorist. The bicyclist needs to always assume that the motorist does not see them.

Rules of how to use the Green Bike Lanes

What are they made of?

The material used for the Green Bike Lanes is a skid resistant asphaltic pavement marking. The material consists of three different components; resin, powder hardener, and aggregate. The elements are mixed thoroughly and applied either by pouring and spreading, or by spraying the designated location. This material has features that include:

  • Skid-resistant surface
  • Alerts drivers to "special-use" traffic lanes
  • Variety of colors and aggregate sizes
  • Easy application
  • Fast cure time
  • Strong adhesion to concrete and asphalt surfaces
  • Long-lasting
  • Positive demarcation
  • Enhances traffic calming
