Human mobility and, in particular, commuting patterns have a fundamental role in understanding socio-economic systems. Analysing and modelling the networks formed by commuters, for example, has become a crucial requirement in studying rural areas dynamics and to help decision-making. This paper presents a simple spatial interaction commuting model with only one parameter. The proposed algorithm considers each individual who wants to commute, starting from their residence to all the possible workplaces. The algorithm decides the location of the workplace following the classical rule inspired from the gravity law consisting of a compromise between the job offers and the distance to the job. The further away the job is, the more important the offer should be to be considered for the decision. Inversely, the quantity of offers is not important for the decision when these offers are close by. The presented model provides a simple, yet powerful approach to simulate realistic distributions of commuters for empirical studies with limited data availability. The paper also presents a comparative analysis of the structure of the commuting networks of the four European regions to which we apply our model. The model is calibrated and validated on these regions. The results from the analysis show that the model is very efficient in reproducing most of the statistical properties of the network given by the data sources.
International Symposium on Cellular Automata Modeling for Urban and Spatial Systems
November 8–10, 2012 — Oporto, Portugal
CAMUSS, the International Symposium on Cellular Automata Modeling for Urban and Spatial Systems, will be held in Oporto, Portugal from November 8 to 10, 2012.
After more than three decades of intensive research on the development and application of cellular automata (CA) models to simulate urban and spatial systems, it is the time to gather all the researchers that have participated in this area of research. This Symposium is expected to be a reunion of the CA community across the world, bringing together all the generations of researchers who have gave to CA modeling the complex scientific structure that it currently has.
AAMAS is the largest and most influential conference in the area of agents and multiagent systems, the aim of the conference is to bring together researchers and practitioners in all areas of agent technology and to provide a single, high-profile, internationally renowned forum for research in the theory and practice of autonomous agents and multiagent systems.
10 years ago Alasdair Turner (2002) reviewed Self-Organization and the City by Juval Portugali. Now, the same author published a new book where cognition pops up in the title. The review by Turner was very positive and I am also inclined to express my admiration: What a book! It took me some time to digest it, but I strongly recommend it to scholars who work on spatial agent models. On the other hand, I would like to warn the readers as the book suggests a synergetic approach to agent-based modelling, which many of us are unfamiliar with. Moreover, although being almost perfect, the book missed something that crept into my brain while reading these 400 pages.
The forthcoming 5th International Conference (CHAOS2012) on Chaotic Modeling, Simulation and Applications (www.cmsim.org) was decided by the previous Committee meeting in June 2011 following the successful organization of the 4th ...
