COMMUTER is a spreadsheet-based computer model that estimates the travel and emissions impacts of transportation air quality programs focused on commuting. The model is particularly useful for programs such as those recognized under the EPA’s Best Workplaces for CommutersSM and other Commuter Choice Programs.
When to Use This Tool
This tool is most useful for development impacts assessments focused on:

Travel and emission effects resulting from transportation control measures, including percentage of trips eliminated, percentage of trips shifted from the peak to off-peak period, baseline and final peak, off-peak and daily VMT, baseline and final peak, off-peak and daily vehicle trips, and changes in total daily emissions for each pollutant.
