Joan Serras
Joan is a Research Fellow in the Dept of Design, Development, Environment and Materials. He is currently working on improving the accuracy of the Milton Keynes model using TRANSIMS and also on the role of microscopic models for CO2 emissions estimation. Joan finished his PhD on "Multidimensional Multilevel Representation for Microscopic Traffic Simulation Models" in 2007. This research involved familiarisation on the TRANSIMS urban model, implementation of an algorithm based on the theoretical formulation from Johnson's Multilevel Representation (Johnson, 1981), and study of the dynamics arising from the integration of both. Joan's research interests include microscopic transport models, GIS, multilevel representations, cellular automata and traffic flow theory.

Research Interests
My main research interests lie in the field of microscopic transport
modelling systems, specifically those packages dealing with
disaggregated demand (activity-based approach) and large urban areas
(≥10^5 inhabitants). The disciplines those packages interact
with are geography (GIS databases), demographics (Census databases),
transport planning (land use planning) and traffic flow theory
(driver behaviour models).
My current research focusses on the use of the output data of one of these packages, TRANSIMS, to implement a Multidimensional Multilevel Representation formulated by Johnson (1981).
My future research plans are to build on the foundations
of my PhD to further investigate the effects of such integration,
focussing on the possibility of generating a more effective dynamic
traffic assignment for such modelling systems.
