Towards sustainable dynamic traffic management

Dynamic traffic management (DTM) measures are potentially powerful measures to not only improve network efficiency, but also to reduce externalities of traffic (e.g. emissions of substances, noise and safety). In current practice the deployment of DTM measures (or DTM-strategies) focuses on improving efficiency on a local level. Further the assessment of DTM is concerned with a number of predefined strategies where not always behavioral responses are taken into account. However, because of spatial correlations DTM has network wide impact, and the predefined set may not contain well performing strategies. So ideally the assessment and selection of a DTM strategy should be based on several network performance measures, including externalities, where potentially all possible strategies are considered. This can be achieved by optimizing multiple objectives on a network level, where decision variables are DTM measures. Previously no research has been done on how these objectives relate and what strategies can be effective, taking traffic dynamics and route choice behavior into account.
