BACKGROUND



New York City
(NYC) Subway is the
largest rapid transit
system in the United
States
Express services
make fewer stops
mainly at major
stations by skipping
some minor stations
and cover longer
distance within a
short period
local services stop at
every single station

BACKGROUND (CONT.)
NYC subway
provides both
express and local
services
 Some subway lines
have both services
 Moat of the transit
service arrangement
were determined in
the middle of
twentieth century.

PRIOR RESEARCH


Transportation systems and land use are interrelated
Numerous of studies defined the relationship between land use
and transit ridership (Banerjee, Myers, and Irazabal, 2005; Brown, 2012;
Zhuang, 2014 and others)


The most relevant research conducted in New York, which
described the co-developed relationship between subway
stations and residential and commercial land use. The result of
the study revealed that the subway network was a leading
factor of commercial growth (David, 2011)
However, none of the research compares the relationship of
express vs. local transit services on surrounding land use.

Objectives
OBJECTIVES AND HYPOTHESES
• Compare the land uses in the catchment
area surrounding express stations and local
stations
• Evaluate for a single subway line (“A”
train)
Hypotheses
Residential land use is higher near express stations than local stations
Commercial activity is higher near express stations than local stations
Population density is higher near express stations than local stations
Subway ridership is higher in express stations than local stations

METHODOLOGY
Background on “A” train
The A train serves both express and local services, as well as covers
31 miles from Inwood in Manhattan to Far Rockway in Queens
Catchment Area of Each Station
Based on 𝑇𝐶𝑄𝑆𝑀 𝑖 , half a mile catchment area is considered for each
station containing the surrounding land use data
Compare Express Stations with Local Stations
Three dimensions -land use, population densities, and subway
ridership within half a mile catchment areas are calculated for each
station

Brooklyn and Queens boroughs are residential land dominant. About 60% of
land is shared by residential buildings around local stations in these two
boroughs.

FUTURE RESEARCH
Only three dimensions are considered. In future,
other dimensions like-residential building price,
economic activity, income of household, and auto
ownership could be included
 Statistical tests could be conducted to understand
the strength of the relationship between local and
express stations land uses
 Understanding the variation of land use pattern
in catchment areas would greatly enhance the
ability to provide efficient and effective transit
services
