Recently, bike lanes in high traffic or congested areas have been identified with color markings to increase lane visibility. Color markings have been used in Europe for a number of years and more recently in the USA. For example, Portland, Oregon, and Cambridge Massachusetts mark the pavement in blue while Burlington, Vermont uses a blue-green color.
The unit cost provided is for a thermoplastic application. Usually 2 per lane per intersection.
How the Default Unit Cost was Determined
In a study conducted by Hunter et al. in Portland, Oregon, the city identified seven different materials that can be used to mark the pavement. The materials were tested for durability, visibility, and cost. Recent experience by the City of Cambridge has identified thermoplastic as the material of choice due to its combination of durability and affordability. The cost of materials and installation in Cambridge was reported to be $10/square foot.
