Intersections can the most dangerous place on the roads for people, whether you walk, bike or drive. 

Designs for intersections should minimize conflicts between people in vehicles and vulnerable road users, people walking and biking, by heightening the level of visibility, denoting a clear right-of-way, and facilitating eye contact and awareness with other road users.

Intersection treatments, such as using colored pavement markings, can help resolve both queuing and merging maneuvers for bicyclists, highlight proper lane positioning, increase motorist yielding behaviors, and is a more attractive facility for many people on bikes.


Colored pavement within a bicycle lane increases the visibility of the bike lane, identifies potential areas of conflict, and reinforces priority to bicyclists in conflict areas. Colored pavement can be utilized either as a corridor treatment along the length of a bike lane or as a spot treatment, including bike boxes, conflict areas, or for intersection crossing markings. 

Colored Bike Facility Benefits

  • Promotes the multi-modal nature of a street corridor.
  • Increases the visibility of bicyclists.
  • Discourages illegal parking in the bike lane.    
  • When used in conflict areas, raises motorist and bicyclist awareness to potential areas of conflict.    
  • Increases bicyclist comfort though clearly delineated space.    
  • Increases motorist yielding behavior.    
  • Helps reduce bicycle conflicts with turning motorists.    

Typical Applications

  • Within bike lanes.
  • Across turning conflict areas, such as, vehicle right turn lanes.
  • Across intersections, particularly through wide or complex intersections where the bicycle path may be unclear. 
  • Across driveways and stop or yield-controlled cross-streets.
  • Where typical vehicle movements frequently encroach into bicycle space, such as across ramp-style exits and entries.

The City of Redding is trying two different products of the green pavement markings to see which one better performs in our area.

The first are preformed thermoplastic pavement markings that contain uniformly distributed glass beads is designed to be used in heavy traffic locations. Anti slip and skid resistance is built in. 

The second is a liquid hot process that is applied in a similar way as thermoplastic striping like edge-lines and crosswalks by doing a controlled pour while in motion. It contains anti skid materials designed to provide continued anti slip and skid resistance as the material wears down.

The "green stuff" actually isn't paint at all, it is thermoplastic. It comes in sheets.
