NJ Transit Ridership Patterns

The NJ Transit railroad carries nearly 90,000 passengers per day to and from New York Penn Station – the busiest rail station in North America. The majority of these passengers are commuters, who live in bedroom communities dotting northern New Jersey. The construction of these railroads – mostly in the late 19th and early 20th centuries – reveals patterns of urban growth centered around New York City. Like spokes on a wheel, these rail lines converge around Midtown Manhattan. As with many urban rail networks, this growth pattern makes it easier to travel from center to periphery than between towns on the periphery.

Hover over individual dots to reveal corresponding station statistics. Dot color corresponds to train line. White dots are for stations where multiple lines intersect. Dot size corresponds to number of riders per day. Large dots for busy stations, and small dots for less busy stations. For each station, the average number of riders is listed. This average should control for any aberrations in ridership, such as a particularly busy weekend, line closure, or major event in New York. These visualizations are derived from data NJ Transit provided me, here and here.

The map above shows weekday ridership patterns. Clearly, the movement patterns are New York City and Newark centric – where the jobs are. The next two busiest stations are Secaucus Junction and Hoboken – but these stations are not primary commuter destinations. Rather, they operate as transfer points. Weekday commuters collected from stations along the Pascack Valley, Bergen County, and Main Line are mostly headed to destinations in New York City. And because no trains on these lines arrive in New York City, they must transfer at Secaucus (to another NJT train) or at Hoboken (to PATH / the Hudson River ferries).

This map shows Sunday ridership. Unsurprisingly, the riders per station are correspondingly less because NJ Transit is mostly a commuter railroad. Stations are on average 66% to 75% less busy on weekends. The thirteen stations along the Montclair-Boonton Line – between Bay Street and Denville – are also entirely closed on weekends and serve no riders. The one line, however, that seems to be only slightly less busy on weekends is the Atlantic City Line – possibly because this line is popular on weekends for people traveling to the casinos and beaches there.

The infographic above lists weekday ridership by station. Notice the large gap between the first four stations and all the others listed. Keep in mind that a lot of this data implicitly involves double-counting a single passenger. For instance, someone riding from their home near Bay Street (Montclair) to Penn Station (New York) will be counted once in the morning when they clock-in at Bay Street, and then again once they return through New York Penn the same evening.

Writing Here Is New York in 1949, E.B. White has the following to say about the suburban commuter:

.

The commuter is the queerest bird of all. The suburb he inhabits … is a mere roost where he comes at day’s end to go to sleep. Except in rare cases, the man [or woman] who lives in Mamaroneck or Little New or Teaneck, and works in New York, discovers nothing much about the city except the time of arrival and departure of trains and buses, and the path to a quick lunch…. About 400,000 men and women come charging onto the Island each week-day morning, out of the mouths of tubes and tunnels…. The commuter dies with tremendous mileage to his credit, but he is no rover…. The Long Island Rail Road alone carried forty million commuters last year, but many of them were the same fellow retracing his steps. (p.18-21)
