The next decade will see numerous decision support tools emerge for traffic management. This is mainly due to the fact that all pieces necessary for the development of these tools are now at our disposal, and have emerged in the recent years. This includes sensing, communication, high performance and modeling capabilities. All over the world, several Departments of Transportation have started to investigate the steps required to build tools capable of advising humans in charge of optimization of mobility at the scale of a city. Specific breakthroughs are already visible in Australia, France and in the Netherlands. Such tools require significant amount of modeling (the interplay of various control schemes on a distributed parameter system, which can be modeled as a partial differential equation), which will be presented in the first subtopic of the workshop.
