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. DOT counts cyclists monthly from April to October, with three additional counts in May, August and September for a total of 10 counts per year.
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.
