Routes on this corridor

RouteBaseline mph Riders/dayFull-run time (derived) Trend
M1 5.32 7,589 96.0 min full run
M2 5.74 6,095 97.8 min full run
M3 5.02 8,255 130.1 min full run
M4 5.19 10,670 122.0 min full run
Q32 5.6 6,717 80.4 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 card scopes this project to Madison Avenue from 23rd to 42nd Street. The M1-M4 run Madison through the project area and the Q32 runs it from about 32nd Street; the M57, M66, M72, and M31 touch Madison only between 57th and 72nd and are excluded. (Verified July 11, 2026; corrections welcome.)
