Background on Vision Zero

Vision Zero Chicago (VZC) is the commitment and approach to eliminating fatalities and serious injuries from traffic crashes.

Much more information is available in the Action Plan, and the City’s website: https://www.chicago.gov/city/en/depts/cdot/supp_info/vision-zero-chicago.html

The plan emphasizes reporting and accountability in an transparent manner. To this end, the VZ committee has requested a public facing dashboard that communicates our progress toward Vision Zero goals, which can be referenced internally and externally.

The Vision Zero Dashboard

The purpose of the proposed dashboard is to help Vision Zero Chicago achieve its mission, and increase transparency and accountability.

There are a wide variety of ways this information could be communicated, and technologies that could be used. We feel that it would be best to begin with open source software and open data. The most relevant data that we would want to communicate is already publicly available on the open data portal: https://data.cityofchicago.org/Transportation/Traffic-Crashes-Crashes/85ca-t3if

The data sets include crash, vehicle, and person information reported into our eCrash system. These data sets are updated on a daily basis.

We are also working with IDOT to determine how we can incorporate data for prior years so that we can accurately measure progress toward goals, and identify trends.

Elements of the dashboard:

Progress toward Vision Zero goals
Cause of crash
Was the crash in a High Crash Corridor
Demographics impacted by crashes
Summaries by time of day, day of week, season
Anything that would provide insight to help prevent crashes

Examples of dashboards from other cities, and Illinois:

Technical Details

Please fork, clone, push, and then issue pull requests to the Chicago repository. Please use the issues in Chicago for general discussion, unless you have topics specific to your group. The ddiscussion tag indicates discussion areas.

To install geneorama please uuse devtools, devtools::install_github("geneorama/geneorama")

Please use the metadata for the crash data in data-idot to understand the nuance of the crash data.

Gnenerally speaking, reference data can be found in the resources\ folder, including a Word Document with dashboard examples. The final example in that document is a template created by CDOT which represents a great starting point. From a technical perspective, check out the example-shiny-crashes\ app.

** Please use issues! Let us know what you're thinking.
