Simulation, Dynamics and Control of Freeway Traffic

This paper presents the Simulator of Intelligent Transportation Systems (SITS).The SITS is based on a microscopic simulation approach to reproduce real traffic conditions in an urban or non-urban network considering different types of vehicles, drivers and roads. A dynamical analysis of several traffic phenomena, applying a new modelling formalism based on the embedding of statistics and Fourier transform, is then addressed. The results of using classical system theory tools point out that it is possible to study traffic systems, taking advantage of the knowledge gathered with automatic control algorithms.
