City plans new bike lanes, but will they serve shortchanged areas?

Chicago has built more than 100 miles of protected bike lanes since Mayor Rahm Emanuel took office. A Tribune report showed that the network of protected bike lanes, along with the Divvy bike-share system, shortchanged minority areas of the city.

For this story, I compared the added bike infrastructure with city demographics using GIS software. This analysis drove an interactive visualization and the results also informed the writer’s reporting. Here is the report the visualization accompanied. 

I spearheaded the analysis and design, while another Tribune staff member assisted with the development of the interactive map.

Here is a link to the visualization. A screen grab is below, and if the link is dead an archived version is here.
