September, 12-16, 2016. Facing an increasingly complex traffic, optimal exploitation of existing infrastructure is a challenging problem. Control systems tools can bring here innovative and well-performing solutions, thanks also to new technologies involving a multitude of sensors and actuators. This Summer School aimed at presenting the main mathematical tools which allow modelling, predicting and controlling the traffic, starting with the classical ones to the most advanced ones, including optimal routing and cooperative ITS. To this end, domain experts have been present to share their expertise and cutting-edge research results.
