Hello Transportation SWATeam,
Per our discussion today, here are a couple of files and links.
- The most recent version of the Clean Air Cool Planet emissions calculator.
- Excerpts from the calculator as related to transportation emissions. Note the tab called “data for average commute” explains the current math for the average commute distance.
- 2007 mode-choice survey details: http://www.ihavemiplan.com/results/index.html
- 2011 mode-choice survey details: https://icap.sustainability.illinois.edu/project-update/mode-shift-update
Both of the mode choice surveys were done in completely different ways and not exactly for the purpose we are using them. It would probably be good to develop a survey specifically for this calculation purpose that can be administered by the UI in future years.
