Routes on this corridor

RouteBaseline mph Riders/dayFull-run time (derived) Trend
BX39 6.26 4,023 85.0 min full run

Full-run time is derived: route length divided by average speed. Rider counts are fare-paid boardings, weekdays 7am–7pm, on tracked local routes. The plan's own rider figures count all riders, all day, so they run higher.

How this corridor was mapped to routes

The Bx39 is the White Plains Road trunk. The Bx36 crosses for about half a mile and is excluded, consistent with how other partial overlaps are handled. (Verified July 11, 2026; corrections welcome.)
