Does the lane approach a congested highway/interstate on ramp, is it in a non-curb lane, do more than 30 buses per hour use the lane, or does the bus have a dedicated signal phase?
No to All. Yes to any.
Use red paint (full block) and "bus only" lane markings.
Could a "reasonable" motorist accidentally end up in bus lane due to mixing, crossing, turn movements (from driveways or side streets) or lane configuration changes (such as start/end of BAT lane)?
Use red paint (at start/end of block or key locations) and "bus only" lane markings.
