Abstract:
This report was prepared under the “Improvement and Operation of the Vermont Travel Model” contract with the Vermont Agency of Transportation (VTrans) in the 2011-2012 year of the contract. The primary objective of the project was to continue to improve the Vermont Travel Model toward the goal of being a comprehensive, effective predictor of travel behavior of Vermonters. The purpose of this report is to document the improvement activities which were completed toward this goal in the 2011-2012 (Year 4) year of the contract. Other activities undertaken in Year 4 of the contract are documented separately. The Vermont Travel Model is a series of spatial computer models which uses the land use and activity patterns of traffic analysis zones (TAZs) within Vermont to estimate the travel behavior of Vermonters. Origin and destination tables are created which describe the number of expected trips between each pair of zones. Accommodations are made for commercial-truck trips, trips made by non-automobile modes, and the occupancy characteristics of passenger vehicles. The final outputs are traffic volumes by roadway link in the state-wide roadway network. The model currently includes 936 zones and 5,250 miles of highway network. In Year 3, the TRC updated the Model with data from the 2009 National Household Travel Survey and the Vermont Department of Labor. In Year 4, land-use characteristics in the model were updated with new residential information from the 2006-2010 American Community Survey (ACS) and the 2010 US Census, and new employment information for 2009 from the Bureau of Economic Analysis (BEA). Land-use characteristics updated included using the cross-classification of number of household members and number of household workers by town, the number of households by Census block, and the number of jobs by industry by County. Road network characteristics were also updated, reflecting modifications or improvements to the network since 2000. The characteristics of roadways that were updated included speed limits, alignments, and capacities. In addition, the TRC began the investigation into the development of the freight component of the Vermont Travel Model. The findings of this initial investigation, along with the TRC’s recommendations for the Model, are summarized in this report. This report contains a description of the Vermont Travel Model, including its history and its current functional capabilities, a description of the data used in this update, a description of the methods used to process data for use in improving the Model, a summary of the results of the update, and a summary of the results of the investigation into the development of a freight component to the Model.
