Class Project Report Sustainable Air Quality, EECE 449/549, Spring 2009 Washington University, St. Louis, MO Transportation Carbon Emissions Model - Midterm for Commuting Instructors: Professor Rudolf B. Husar, Erin M. Robinson More details on the class wikiclass wiki Students: Kerry Herr Katy Josh Michael Neel
Approach to the Commuting Model -Verify population change in is on previous track/trend -Add long distance commuting to the model “Driving or flying home for the holiday” -Coordinate PMT with air travel model -Air (PMT) + Ground (PMT) = total PMT for long commuting -Determine the number of long distance commuters - Obtain zip code data to determine the distances -Determine how many long distance commuters live close enough to drive, how many fly home -Make assumption about how far people are willing to drive (~7 hours?)
Approach to Commuting Model -Update Student/Faculty/Staff population per zip code data Parking Permit/zip code info for Use Google maps for actual local driving distances -Verify Color coding of permits has been accounted for - break out all permit colors for analysis -Make assumptions about how different permits correspond to amounts of driving -Coordinate limits of model with the shuttle group -Commuting model will stop at the edge of campus and shuttle model will handle all on campus travel.
