We present a agent-base model to simulate the citizens mobility in a urban space where different transportation systems are at disposal. The request of mobility is determined by the "chronotopic areas": i.e. urban areas where time-dependent activities are installed and attract the citizens according to their social categories. The core of the model is a decision mechanism for the agents based on a daily program, which chooses the transportation means and the roads to reach the scheduled chronotopic areas. The decision mechanism depends on the social categories of the agents, on the informations at disposal, on the attraction force towards a chronotopos and on some random choices. The daily program can also be upgraded according to the informations given to the agents. The finite volume congestion effects are present in the private transportation and in the finite capacity of the public means whereas the crowding in the chronotopic areas causes the extension of the stay in the areas themselves. Some properties of the model are discussed in the framework of complex systems and the results of simulations on real situations are presented.

Abstract

We present a agent-base model to simulate the citizens mobility in a urban space where different transportation systems are at disposal. The request of mobility is determined by the "chronotopic areas": i.e. urban areas where time-dependent activities are installed and attract the citizens according to their social categories. The core of the model is a decision mechanism for the agents based on a daily program, which chooses the transportation means and the roads to reach the scheduled chronotopic areas. The decision mechanism depends on the social categories of the agents, on the informations at disposal, on the attraction force towards a chronotopos and on some random choices. The daily program can also be upgraded according to the informations given to the agents. The finite volume congestion effects are present in the private transportation and in the finite capacity of the public means whereas the crowding in the chronotopic areas causes the extension of the stay in the areas themselves. Some properties of the model are discussed in the framework of complex systems and the results of simulations on real situations are presented.
