Building and Calibrating Activity-Based Models: Stories from the Trenches


Note, no video/audio recording is available for this webinar because it was not recorded


Date: Thursday, May 27, 2010
Time: 2:30pm - 4:30pm Eastern Time
Location: Online

Intended Audience

This webinar is intended for anyone who is interested in a close-up view of the process of building an activity-based travel model, including those who already have such a model and would like to see what another agency's models look like in detail, those who don't have such a model but are thinking of trying to get one, or those who aren't planning to "take the plunge" anytime soon, but would like to keep track of developments in the field.


The webinar will cover the Denver Regional Council of Governments' (DRCOG) process of developing its activity-based model "from soup to nuts", beginning with the initial planning stage. We'll air the dirtiest laundry we feel we can get away with (pretty darn dirty!), with the aim of giving webinar attendees a sense of where the trouble spots were for us, and how others might avoid them! Topics will include:

You may not be thinking of designing either your project process or model the way we did, but this webinar should help you think through the realities of each step in the process, however you plan to do it.


Erik Sabina, P.E. is DRCOG's Regional Modeling Manager, and has 27 years experience in travel demand forecasting and computer-based modeling and simulation. He holds a BS in Aerospace Engineering from the University of Colorado, and an MS in Transportation from the Massachusetts Institute of Technology.

Suzanne Childress is a Senior Modeler at DRCOG, and has eight years experience in travel demand forecasting, both as a consultant and in the public sector. She holds a BS in Mathematics from Carleton College, and an MS in Industrial Engineering from Northwestern University.
