ATMA-MODeRN : development of a multi-objective traffic management decision tool

In policy documents concerning Transport sustainability plays an important role. Main goal is to achieve a transport system that is fast, clean, safe, quite and reliable. Further the transport system should contribute to the main goals concerning the emission of CO2 and energy use. One of the ways to achieve all of this is through a better utilization of the existing infrastructure, for instance using traffic management measures. However, it is not really known if all these goals can be reached, but also how these goals relate to each other and what measures should be taken to actually achieve all of this. When the project started the main focus was on network efficiency in terms of travel times, delay etc. Other goals were considered but not as a main objective, more as a constraint. Traffic management was evaluated in terms of network efficiency, and one was satisfied when traffic safety, noise or air pollution had not become worse. In ATMA these constraints have become objectives. It is studied how the objectives can actually be quantified in a workable manner, what the effects of specific measures are for the all goals, how reliability and the robustness of networks can be determined, and how a transport network can be optimized using multiple objectives. Further it is studies how traffic control can be improved, for instance using a distributed control, or an anticipatory control framework.
