Simulation is a strong tool for traffic engineers to investigate phenomena, to test control strategies and their impacts, but it also has its limitations. The data needed to calibrate the simulation is limited, mostly from low quality, or - when looking into behavior - not available at all. For the latter on, methods ranging from simple surveys to highly technical experiments in driving simulators are used. The trade off is between the number of people a survey/experiment reaches and the level of realism one can generate to get accurate information. In this paper we are introducing a behavior studies platform based on 3D Internet that will allow researchers to reach out to a broad audience with a high level of realism, but limited technical effort. The system is now in the final testing stage before being utilized to test drivers' reactions on intelligent traffic system (ITS) measures to reduce the emission of CO2. ©2010 IEEE.
