The largest number of bike crashes occur at intersections. Travel lanes for autos continue to the intersection. Often the turn lane is also marked with bots dots or dashed lines. Bike lanes however terminate ahead of the intersection. The engineering consideration is for shared space. However with vehicle speeds typically over 35 mph, multiple lane configurations which force irresponsible drivers to hold their position, the situation is quickly dicey.
Discretionary cyclists press left early to provide motorists with a predictable vehicle that they can plan around, often slowing down through the intersection, until they can pass once the bike lane resumes. But other cyclists endanger themselves by trying to share the space. The police typically take the side of cultured or perceived wealth, the motorist. The engineer has standards on his side. Between words and numbers the common traveller is unable to “leave and return unharmed and without fear by land (Magna Carta 42).”
In an ideal situation all marking should be dropped. The intersection as a clear space would be a common for all vehicles to be used at their discretion and caution. A land use allocation on modal footprints would imply that there should not be many intersections.
