Bicycle Counts

In-Season Cycling Indicator

DOT tracks long-term trends in New York City cycling using the In-Season Cycling Indicator. The Indicator is derived from counts of bicycle traffic over the four East River Bridges, the Staten Island Ferry, and on the Hudson River Greenway that have been taken annually since 1984. Starting in April 2014, automated loop induction counters were used on the East River Bridges replacing manual counts by human enumerators; the Staten Island Ferry and Hudson River Greenway still utilize human enumerators. To best equate the automated count data with historical data, each monthly count consists of average daily volume for every non-holiday weekday without precipitation. A typical monthly loop induction count now consists of between 11 and 17 days of data while the manual system consists of 1 to 2 days. Counts are reported for the period between April and October.

All-Year Cycling and Winter Indicators

In 2008, DOT began counting cyclists in winter months and off-season cycling has seen significant growth—indicating that more and more New Yorkers are cycling year round as part of their transportation routine.

Bicycle Screenline Count

The Bicycle Screenline Count tracks bicycle traffic entering and leaving the Manhattan core via the East River Bridges, the Staten Island Ferry, each avenue at 50th Street and the Hudson River Greenway. DOT conducted its first comprehensive “screenline” count of bicyclists in 1980. The count has been conducted annually since 1985. Since 2007, DOT has counted three times a year, in May, August and September. The count had historically been conducted in July or August. The count is performed midweek (Tuesday, Wednesday or Thursday), and includes a 12-hour count (7 am – 7 pm) and, since 2007, an 18-hour count (6 am – midnight). The data collected through the screenline count is used to derive the Commuter Cycling Indicator.

The data are incorporated into New York Metropolitan Transportation Council's annual Hub-Bound Travel Report. NYMTC also collects data on cycling in the five boroughs and suburbs through the NYMTC Bicycle Data Collection Program.
