Description of Project Our aim is to discuss some capital points, limits and possibilities in order to describe, explain, predict and govern the urban and metropolitan mobilities in a interdisciplinary context with the contribution of physicists and mathematicians, engineers, urban planners and sociologists. The common background is complexity as the key to understand phenomena in multi-agents systems, characterized by individual dynamical and cognitive properties. It is well established that the City is a complex system where biological, physical, social historical, aestetics, information components interact to produce urban structures, self-organized processes and evolution dynamics. The purpose of this conference is to build a common area for the fundamental scientific discoveries, the mathematical and physical modeling, the information projects oriented towards e-governance of the cities. The development of the concept of complexity emerging from biological and physical sciences has given rise to the study of dynamical and statistical properties of living systems. In recent years several models have been proposed to simulate the peculiar properties of living systems that cannot be explained by means of fundamental laws of Physics but require the introduction of information based interactions, memory and learning processes and cooperative behaviors. A big effort is going on to introduce the right mathematical tools that allow to explain and control the dynamics of complex systems, but most of the results are still based on computer simulations. Urban systems modeling is one of the main research topics in physics of complex systems and the problem of mobility is becoming extremely important due to its implications on the life quality. Various mathematical models have been proposed in the past to study the mobility problem. The traditional approach was essentially based on traffic simulations that reproduced the origin-destination mobility related to the work time-schedule. Recently the sociologists and the urban planners have pointed out the necessity of taking into account new kinds of mobilities based on individual choices. As the consequence microscopical models were introduced based on decision dynamics intended to reproduce the citizens behaviors (agent based models). One of the main problems remains the comparison of model results with the reality. This topic requires a close interdisciplinary collaboration among physicists, mathematicians, sociologists and experts in urban and transport planning. There are intrinsic difficulties to collect sufficiently long time series of data for one or more observables and moreover the definition of experiments in the science of complex systems is still a debated problem, for which the Galilean philosophy is not suitable. This is a crucial point for future applications of the scientific results and toward the e-governance of the cities: i.e. the introduction of Information and Communications Technologies that both require and 4
promote a high degree of participation by peripherical units of the systems in order to induce two-way, highly interactive decision-making processes. The international conference Physics and the City promoted by the University of Bologna UniboCultura will gather some of the major experts in planning, sociology, transportation systems and physics of complex systems to discuss the present state of the art with applications and the future perspectives. The conference will be also opened to experts coming from public administrations and from private/public companies. www.physycom.unibo.it 5
