The Four Phases of Model Development Data Collection Model Architecture Model Estimation Panic BEYOND THE GTA 3
Is the estimation dataset compatible with the application dataset?
Estimation vs. Application Estimation: Household travel survey Place of Work Distribution: TTS vs. Census Application: Census Survey expansion is never perfect Potential solutions: • LOCAL SURVEY RE-EXPANSION • CALIBRATE POTENTIAL BIAS 2016 TTS 2016 Census BEYOND THE GTA 5
Are all critical travel markets being captured?
Critical Travel Markets Not all trip-makers are captured by Peterborough Transit Ridership by Fare Type household travel surveys (or the Census) U-Pass (~55%) Through travel; student travel Adult (~30%) Potential solutions: 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 • THIRD-PARTY DATA • SATELLITE SURVEY BEYOND THE GTA 7
What are the local travel “quirks”?
Travel Quirks Best to capture quirks in architecture and estimation You have to know what you’re looking for, so do your research! Potential solutions: • DETERMINE “MOTIVATION” FOR QUIRK, AND MODEL IT! BEYOND THE GTA 9
