7.65 mph on the corridor's own segments (segment-clipped baseline)
−1.4% July 2026 vs July 2025 (6.23 to 6.14 mph). Pre-plan months on these routes swung −11.0% to −1.6%. Too soon to call.

Routes on this corridor
| Route | Baseline mph | Riders/day | Full-run time (derived) | Trend |
|---|---|---|---|---|
| B38 | 5.96 | 9,696 | 63.5 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 plan text scopes this corridor to improvements along the B38. An early automated match added the Q50 by mistake - a same-named Lafayette Avenue in the Bronx - and was corrected. (Verified July 11, 2026; corrections welcome.)
