Speaker: Peter Stopher, Professor of Transport Planning, Institute of Transport and Logistics Studies, University of Sydney
Topic: Using a GPS Panel to Evaluate Travel Behavior Changes
When: Friday, May 18, 2007, 12:00-1:30 pm
Where: 204 Urban Center



Current research at the Institute of Transport and Logistics Analysis of the University of Sydney, under Professor Peter Stopher, has been concentrating on using personal GPS devices to collect travel behaviour data of individuals. In this seminar, Professor Stopher will outline the several projects that have been conducted and are currently underway that are using GPS. He will describe the survey procedures, and then provide an overview of some of the results emerging from collection of such data. Of particular interest is that the GPS surveys are being conducted in most cases by using a panel, with at least two waves of data collection, and that panel members carry the GPS devices for anywhere from one week to one month. Initial studies of the variability in daily travel, where there are no fatigue effects from recording multiple days in a diary, are showing some interesting patterns and leading to some important conclusions.
