About this Event

Presenter: Konstadinos (Kostas) G. Goulias (Laurea Magistrale, MS, and PhD in Civil Engineering) is a Professor of Transportation at the UC Santa Barbara Department of Geography since 2004. From 1991 to 2004 he was Professor of Transportation in the Department of Civil and Environmental Engineering of PennState University. His research is on Large Scale Transportation Systems Modeling and Simulation, Travel Behavior Dynamics, Sustainable Transportation, Economic Geography Travel Survey Methods, Geocomputation and Geoinformation. He chairs the International Association for Travel Behaviour Research and is the co-Editor-in-Chief of the journal Transportation Letters.


Abstract of Lecture: Activity-based models are model systems designed for travel demand forecasting and have an approximately 40 year history. Their foundation is on microsimulation and random utility models. These model systems synthetically generate populations and their characteristics, contain sophisticated car ownership and type models, and reproduce daily time allocation and travel of people in households and places. Important outputs include estimates of energy consumption, greenhouse gas and other pollutants emissions, and use of the transportation system. In this presentation I review the basic ideas underlying these models and describe the state of the practice in California to address legislative mandates for Sustainable Community Strategies. I will also provide examples of promising future directions and open science consortia initiatives.
