Projects
- Finding potential new bike parking facility locations – The project uses data (bikeway network, land use, existing bike racks), GIS software, and reverse geocoding to identify specific locations at which bike parking could be installed. This PDF contains the five page paper explaining the project, methods, and tasks, an index of attachments, and attached sample maps and tables. Also included is a detailed procedures/task list that describes how to recreate the project.
Maps
![Quantity (frequency?) of workers bicycling to their jobs](http://farm3.static.flickr.com/2471/3999908370_3b9935cc04_m.jpg "This map shows, with increasing color intensity, the number of workers who rode their bikes to their jobs in each Census Tract in Chicago.
<b>A darker color means more people rode their bikes to jobs in that Census tract than in a lighter colored Census tract</b>.
I chose to work on the Census Tract level for now (while testing the data and my GIS skills) because there it's faster (there are 25,000 Block Groups in Chicago and only 1,300 Census Tracts).
White means that no workers were recorded bicycling to jobs in that Census Tract.
This data comes from the Census Transportation Planning Package, which estimates the number of workers traveling to the Census Tract and by what means did they travel.
I think this took me 3 hours to make. I'm trying to develop a method to prioritize bicycle parking installation as part of my school project.
There are many ways to make a similar map with similar information: I could normalize the number of bicycling workers by the total number of workers in the tract to show which Census tract has the greatest share of workers arriving via bicycle (this would probably move some Census tracts to a lighter hue, like South Deering).
I could normalize the number of bicycling workers by the total area of the tract to show which Census tract has the greatest number of workers per square foot (actually, I have no idea what story that would tell). I could normalize the number of bicycling workers by the total number of workers in all tracts to show which Census tract is the "most green."

![Bike Rack Installation Comparison](http://farm5.static.flickr.com/4059/4293325285_8343290d42_m.jpg "I submitted this to the University of Illinois at Chicago Graduate School's contest, "Image of Research." The purpose of the map is to show the difference in distribution between 2008 and 2009.
All of the data to produce this map is freely available at the Chicago Department of Transportation Bicycle Parking Program Public Interface (wow, long!). The URL is:
<a href=\"http://www.chicagobikes.org/bikeparking\" rel=\"nofollow\">www.chicagobikes.org/bikeparking</a> - easy to remember!
The Chicago Tribune's RedEye used the data from that website to create a similar map about which to write an article.
My project, "Underserved Wards," has been mentioned at several meetings of the Mayor's Bicycle Advisory Council. <a href=\"http://bike2015plan.org/mbac\" rel=\"nofollow\">Read the meeting minutes</a>.
In October 2009, <a href=\"http://www.flickr.com/photos/jamesbondsv/4039121730/\">I posted a similar map</a>. The new map is up-to-date and slightly better designed. The map graphics themselves would be slightly higher quality if I had ArcGIS at home. The original vector PDF files are at work and I didn't have access to them at the time I submitted this map. I created all the text and the new legend in Adobe Illustrator.")
