Roger Chen, "Travel Time Perception and Learning in Traffic Networks" Download: Travel Time Perception and Learning in Traffic Networks Postdoctoral Fellow Transportation Center Northwestern University Time: 1:30 pm Location: 1000 SEO View/download a copy of Dr. Chen's presentation here: "Travel Time Perception and Learning in Traffic Networks". Abstract: The study of human decision making is central to understanding of socio-economic systems, including transportation systems. Understanding and modeling these decisions are essential for the microscopic understanding of macroscopic social phenomena, such as socialization, opinion formation, economic markets, and urban traffic and activity patterns. This research focuses on the last phenomena, namely the decisions underlying time-dependent network traffic flows. An understanding of the human-level dynamics or mechanisms governing traffic flow by means of empirical and numerical studies, can lead to improved insights into the resulting macroscopic phenomena. This research explores the decision mechanisms underlying day-to-day route choice. Their implications on system performance over time is explored through experiments performed using a network performance model, in this case an agent-based simulation model of individual experience given the collective effects arising from the interaction of the agents' route choice decisions. The results indicate that users' perceptions of travel time uncertainty greatly affect the system performance, in particular the convergence of traffic flows. Future directions for the research will be discussed in terms of empirically modeling these decisions. Bio: Roger Chen is currently a post-doctoral fellow at the Transportation Center at Northwestern University. He completed his PhD in Civil Engineering from the University of Maryland, College Park and his MS and BS from The University of Texas at Austin. His current research focuses on modeling the trip-making and activity scheduling decisions of travelers, and understanding their impact on the behavior and performance of transportation systems over time. Furthermore, he has worked on a broad spectrum of projects that range from the design of air cargo screening systems to emissions modeling for transportation planning. |
