A map that focuses on striped bikeways in downtown Chicago.
When you look at your bikeways more abstractly, like in the graphic above, do you see deficiencies or gaps in the network? Anything glaring or odd?
It’s a simple exercise: Open up QGIS and load in the relevant geographic data for your city. For Chicago, I added the city boundary, hydrography and parks (for locational reference), and bike lanes and marked-shared lanes*. Symbolize the bikeways to stand out in a bright color. I had the Chicago Transit Authority stations overlaid, but I removed them because it minimized the “black hole of bikeways” I want to show.
What do you see?
Bigger impact map
This exercise can have more impact if it was visualized differently. You have to be familiar with downtown Chicago and the Loop to fully understand why it’s important to notice what’s missing. It’s an extremely office and job dense neighborhood. It also has one of the highest densities of students in the country; the number of people residing downtown continues to grow. If I had good data on how many workers and students there were per building, I could indicate that on the map to show just how many people are potentially affected by the lack of bicycle infrastructure that leads them to their jobs (or class) in the morning, and home in the evening. I don’t know how to account for all of the bicycling that goes through downtown just for events, like at Millennium and Grant Parks, the Cultural Center, and other theaters and venues.
*If you cannot find GIS data for your city, please let me know and I will try to help you find it. It should be available for your city as a matter of course.
