There were more than 100,000 frequent connections between 344 bike stations in 2014. I visualized only top 1% most frequent connections (stations have more than 677 connections), including 247 bike stations and 1100 bike connec-tions. Most riding activities were happened within speci�ic neighborhoods: Chel-sea and Clinton, Greenwich Village and Soho, Lower East Side(Manhattan), and Northwest Brooklyn.

Cycling activities in the morning are near trains and bus stations. When people commute from their home to transit, they use citi bikes for their �irst mile/ last mile transportation. In the afternoon, cycling activities spread out to attractions in Downtown Manhattan. Cycling activities in the evening and night concentrate on lower east side of Manhattan, a safe popular neighborhood for late night desti-nation.

NEW YORK CITI BIKE PROGRAM 2014 Citi Bike is the largest public bike sharing program in the U.S, providing bicyles for shared use to individuals on a very short term basis. Since a majority of all trips (54%) made in New York city are less than two miles, bike share gives New Yorkers a cheap, easy, ef�icient option to get around the city. It’s also a green transportation that helps reducing emis-sions, road wear, collisions, road and transit congestion, and improving public health.

DataSince its �irst public in May 2013, the program has collected a lot of information regarding to the people who use the bikes, the time and date when they ride, the location where they go and how far they they have been going. In order to visualize these information, I has collected and processed 1GB cycling data for the whole year 2014, including 8,081,216 cycling activities of more than 6,000 bicycles arross 344 bike stations around various neighborhoods in Manhattan and Brooklyn.

AudienceResearchers can see from this visualization riders’ demographics and behavior when they use the bikes. Policymakers, engineers and developers can determine the effectiveness of the program in order to plan infra-structure to engage more users and improve rider experience.

Cycling Activity Density

Question- Demographics and cycling habit of users who use the Citi Bike program ? - Cycling activities during days, months and years? - Where did riders pick up and drop off their bikes ?

There are more cycling activities in speci�ic months, from May to September. These months are the best time of the year, with bright sun and comfortable temperature, allowing riders to enjoy various outdoor activities in the city. Winter season from December to February, with snow, storms and low temperatures, is the worst time for riding. During this time, people prefer use other transportations (trains, bus, cars,..) for their commute.
