Twenty months of the toll (version 1.0.1)

Twenty months in, fewer vehicles are entering Manhattan's toll zone than in its first year, but a count at the door is not a measure of congestion. The speed measures answer different questions: the city's yellow-taxi indicator fell, the state's before-and-after figures rose, and a Google Maps study estimates the zone is faster than it would have been without the toll.

The article's own data file, aggregate statistics cut to what it analyses, and the script that computes every figure in it. Computed from: MTA toll-gantry entries, 5 January 2025 to 19 September 2026; NYMTC Hub Bound counts 1990-2024; the city's speed indicator, fiscal 2009-2026; TLC monthly trip reports 2010 to July 2026; NYC DOT bike-route and bus-lane files as of September 2026.

Public-use microdata are disclosure-protected records derived from survey responses, published by the issuing agency so that no respondent can be identified; synthetic records are generated by SparkyData and correspond to no real person, household or address. Neither may be used to identify anyone.
