A study(external link) into the impact of marked and coloured cycle lanes concluded that where a cycle lane was coloured, drivers appeared to be more aware of cyclists as they gave cyclists more space. Cyclists also appeared to feel safer as they were found to ride further from the kerb.

The study also investigated the cost of implementing coloured cycle lanes.  Maintenance of coloured surfaces varies with the amount of traffic travelling over the cycle lane (eg at intersections), colour retention of the product used, future roadworks and laying conditions. Thermoplastic was found to be the most cost effective product over a 20 year period.
