Posted by Stephen Bauman on Tue Nov 11 11:33:16 2025, in response to Re: Middle Village and Maspeth NIMBYs come out to oppose IBX, posted by New Flyer #857 on Tue Nov 11 08:52:58 2025. the roles of circumferential lines are being minimized here.I have quantified them by looking at 3 different open data sources to estimate latent IBX demand. This is something neither the MTA nor IBX proponents have done. The open data sources are: the MTA's own subway trip origin-destination passenger data for 2023 and 2024 which quantifies travel by subway station; the census bureau's LEHD census for 2019 and 2023 which quantifies journey to work travel by census block; the MTA's 2018 travel survey which quantifies all trips by census block group. There have been numerous anecdotal stories of how the IBX would save time for cherry picked individuals. Brooklyn Borough President Reynoso cited a Bay Ridge resident who started a new job in Jackson Heights. Such trips constitute 0.6% of all trips originating in Bay Ridge, according to these data sources. The demand for travel between all the IBX stations constitute 10% of trips that originate at a proposed IBX station. The figure isn't much better for the IBX's role as a connector for existing lines at Roosevelt Ave. The percentage is 13% of all trips originating at the IBX and those existing lines. how many existing bus and subway lines should hypothetically be removed because most of their stops are within walking distance of other stops. Let's look at one recent expansion, with stops within walking distance of existing stations. That's the SAS between 57th and 96th Streets. 87% of all Manhattan buildings are within 1/2 mile walking distance of an existing subway entrance. The SAS opened on 1 Jan 2017. The number of passengers crossing the CBD boundary have been compiled by NYMTC since the 1960's. This provides a measure of total subway use, which isn't available for most trips. Let's look at the data. Here's the 2016 before data: https://www.nymtc.org/Portals/0/Pdf/Hub%20Bound/2016%20Hub%20Bound/DM_TDS_Hub_Bound_Travel_2016-FINAL.pdf#page=43 It shows the number of passengers using the downtown Lex local and express between 8-9am as: 49,263 Here's the 2017 after data: https://www.nymtc.org/Portals/0/Pdf/Hub%20Bound/2017%20Hub%20Bound/2017_Hub-Bound-August_15_2019.pdf#page=50 It shows the number of passengers using the downtown Lex local, express and the Second Ave local between 8-9am as: 47,693. Essentially there is no change in the number of passengers due to subway expansion for an expenditure of $4.5 billion. |
