3. Sharing is Caring: An analysis of Citi Bike's Discounted Membership for New York City Housing Authority Residents

Presented by Thom Stead (, Transportation Planner, DVRPC

One year after its May 2013 launch, Citi Bike had garnered 100,000 annual members—a figure unprecedented for a bike share program in the United States. As part of this launch, Citi Bike offered $60 annual membership (a 40% discount), to New York City Housing Authority (NYCHA) residents. Despite this discount, NYCHA residents made up less than 1% of the total annual members after the program’s first year. To better understand why the discounted membership was not widely embraced, the author surveyed NYCHA residents living in developments near Citi Bike stations. The findings of this survey were used to develop a series of actionable recommendations that were given to the Citi Bike operations team.

4. Data Analysis at PWD using R and the Shiny Web Application Framework

Presented by Jay Cruz (, Environmental Scientist, and Liz Mannarin (, Civil Engineer, PWD

Philadelphia Water Department (PWD) scientists and engineers recognize the importance of reproducibility in data analysis workflows and are increasingly moving away from spreadsheet-based analyses. These analyses are being replaced by R, a free software environment for statistical computing and graphics, and PostgreSQL, an open source database management system. In this presentation we will discuss the use of this software and an R web application framework package called Shiny, which has been used to create intuitive user interfaces to interact with and manipulate large amounts of data.
