Travel Modeling Workshop
Session 2: Data Set Preparation for Model Estimation
You are cordially invited to attend another in a series of free TMIP Web Knowledge and Information Exchanges. Registration required and limited to 150, first come, first served. Note that only one person per location needs to reserve a connection for the webinar. Please coordinate with your colleagues to avoid duplicate registrations. Your cooperation is appreciated.
Date: Thursday, November 6, 2008
Time: 2:30 PM-4:30 PM (EST) / 11:30 AM-1:30 PM (PST)
Location: Online
Intended Audience
Transportation modelers who have a low to moderate level of familiarity with the estimation and validation of travel models.
Topic
This series of webinars will introduce the development of model estimation data sets, the structures of the various model components, and the procedures for estimating models. The workshop will include lectures, discussion, and “homework,” that participants will be expected to complete between sessions.
This session will focus on how data sets are developed for model estimation. The session will cover the role of data in the estimation process, and the data development process for different types of model components. These components will include household level models such as trip production, trip level models such as mode choice, and aggregate models such as gravity models. The creation of data sets from common sources such as household surveys, including definition of typical fields and records, and combining data from more than one source, will be covered. The homework for the session will be an exercise to set up a small model estimation data set.
