Rack Up (formerly known as bikerackfinder)
Team Members:
Jonathan Freeman
Project Description:
Four-square for bike-racks, mashed up with crime data and friendly competition a la king-of-the-hill.  The app helps users find bike racks on a map(with related crime-data overlays), allows them to “check-in” to bike racks(called “racking up”), report damaged racks, and requests more racks at a particular location.  Users gain points through all of these actions, and can gain extra points by completing extra challenges, such as racking up once in each neighborhood in Chicago.  Additionally, the app will allow users to share if their bike has been stolen, and will provide resources to the user about next steps for reporting the theft.
More generally, this is a proof-of-concept application to demonstrate that the documentation of city resources can be reliably crowd sourced.
Link to the Sustainable Chicago 2015 Action Agenda:
Rack Up correlates with several points on the 2015 Sustainable Chicago action plan.  Most directly, it links to transportation options.  Chicago is becoming more and more bike-friendly, thanks to this and other action plans promoting ridership, and this app is designed to serve the growing constituent of bicyclists here.  In addition to the benefits to the bikers themselves, the app also helps the city.  By documenting previously unknown or undocumented bike racks, easy consuming reports of damaged bike racks, and viewing valuable usage statistics, the city will be granted better visibility into the biking community, which leads to better decisions to help them.  Also, these statistics can be used by third-parties(such as the Alliance for Biking and Walking) to assess the bike friendliness of a city.
Rack Up also has links to:
  • Climate Change – More bikes = less cars.  Less cars = less exhaust.
  • Clean energy – The exhaust from a bike? Breathing out C02.  That’s pretty clean.
  • Economic Development – Studies in many states attribute bike recreation and bike tourism to substantial economic gains ($400M in Iowa, $924M in Wisconsin).  This is not including the health benefits of biking that some states report to be worth up to $400M (Wisconsin).
