5.33 mph baseline, weighted so
busier routes count more (the pre-plan year)
5.05 mph on the corridor's own segments (segment-clipped baseline)
+1.4% July 2026 vs July 2025 (5.41 to 5.49 mph). Pre-plan months on these routes swung −4.6% to +0.3%. Too soon to call.

| Q32 | 5.62 | 6,740 | 80.2 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.)
