Bicycle Lane Paint Markings

Green-painted bicycle lanes that some cities apply at intersections and conflict zones create a visual claim on road space that uncolored bike lanes don't achieve. Paint signals to drivers and cyclists simultaneously where the bicycle path continues through an area where vehicles typically merge or turn. Color choice of green was standardized by the Federal Highway Administration. Consistency across cities means a cyclist traveling between different jurisdictions encounters the same visual language, which reduces the cognitive load of navigating unfamiliar roads. I admire the simplicity of the solution because the paint is cheap to apply, easy to replenish. Visible in rain and low light when combined with thermoplastic markings that have reflective properties built into the surface. Painted lanes work best as part of a connected network. An isolated green patch at 1 intersection surrounded by unmarked road on both sides sends a mixed message about how seriously the city takes cycling infrastructure. Infrastructure tells you where a city's transportation priorities are. Presence or absence of green paint at dangerous intersections reveals whether the bike plan is a policy document or an actual commitment. I think the painted lane is a minimum viable version of protected cycling infrastructure, better than nothing but far less effective than a physical barrier. Cities that are moving from paint to concrete bollards and grade separation are the ones that understand the difference between signaling safety and providing it.
