Simulation of Pedestrian Flows

I have been working with Dr. Jeffrey Adler on applying cellular automata microsimulation for modeling pedestrian flows. Uni, bi-, cross-, and four-directional models have been developed and tested. Our simulation experiments have obtained fundamental flows that compare favorably with established curves as described in the Highway Capacity Manual. The long-term objective of the research is to develop a multipurpose modeling tool for studying pedestrian walkways, concourses, and network flows.

ITS, Driver Behavior, and Intelligent Traveler Information Systems (ITIS)

Over the past 5 years, beginning with my doctoral work (1996), I have researched how traveler information systems influence drivers’ pre-trip and en-route decisions. Much of my work has focused on the development and use of a microcomputer-based travel choice simulator that I developed using the ARENA software. I conducted numerous simulation experiments to assess the effects of in-vehicle traveler information technologies on drivers’ behavioral choice. My research investigates how drivers might use in-vehicle knowledge of a network and assesses the effects of driver information systems on path choice behavior. Research papers on this subject include:

Though many traveler information systems are innovative and make use of cutting edge technologies, they lack real machine intelligence and therefore may be limited in their ability to service the traveling public over the long run. Dr. Jeff Adler and I have been working to develop an Intelligent Traveler Information System (ITIS) that can more effectively respond to drivers’ within day path selection needs and can adapt to changes in drivers’ cognition, spatial knowledge, travel preferences and attitudes over time. Work has included the development of an adaptive fuzzy logic model of driver choice behavior and the exploration of intelligent agent-based systems.
