TravellerSim: An Agent Based Model of Settlements and Situations Shawn Graham University of Manitoba #1 Wren Street Box 240 Bristol Quebec J0X 1G0 fhg1711@yahoo.com Abstract: In this paper, I present an agent based simulation which I use to generate likely patterns of interconnections between settlements in a region, focusing on "situation", the human patterning of social connections over space, rather than "site", the physical location (in contrast to a common trend in much of landscape archaeology).  This methodology, whilst created for study of distributions of ancient settlements in Italy and Greece and their concomitant social networks, also generates social networks which "make sense" for historical North American settlements, at least prior to innovations in transportation technology such as the railroads.  As such, the model (which is a re-implementation and "re-imagination" of an earlier model by Tracey Rihll and Andrew Wilson) captures something "deep" of the human interconnections in a given region. Bio: Shawn Graham is currently the Post-Doctoral Research Fellow in Roman Archaeology in the Department of Classics at the University of Manitoba. He completed his undergraduate degree at Wilfrid Laurier University in Waterloo, Ontario Canada, and his graduate degrees at the University of Reading in the UK. His research interests range from artificial intelligence(s) in archaeology to the construction industry of Rome. He is working on a number of agent-based simulations of various aspects of Roman society and culture, including the emergence of social class, the robustness of Roman social networks (based on the prosopography of Roman brick stamps), and the emergence of trading networks. His fieldwork activities include time as a research assistant at the British School at Rome, excavations at Forum Novum and Silchester, and developing public archaeology and cultural resource management programmes in Western Quebec. His thesis work on social networks and the complex dynamics of the Roman brick industry has been published this year in the BAR International Series (1486) entitled "Ex Figlinis: The Network Dynamics of the Tiber Valley Brick Industry in the Hinterland of Rome".
