Abstract
Due to the ever-growing traffic demand, urban areas all over the world are
facing serious congestion problems. To mitigate the negative impacts of congestion, for many years more roads were built and traffic management measures locally implemented. Regardless all the extra asphalt and local control solutions, nowadays demands are often still exceeding the network capacity at more and more locations within a network. Which led us to the following situation: by solving one bottleneck, others might be easily activated elsewhere. The current focus of traffic management has therefore been put on realizing collaboration between traffic management measures that deal with traffic problems from a network perspective.
However, in the operational field of traffic management there are more objectives to satisfy than just improving the overall network performance. This is related to the many different stakeholders involved in the process of formulating a vision upon the functional use of a road network, as well as our spirit of the times that emphasizes the value of the livability of our environment. Therefore, when planning for the improvement of network performance, it is increasingly important to take note of the many different stakeholder interests. With the stakeholders agreeing on a common vision, systems are needed that are able to operationalize the vision based on realtime conditions at the involved freeways and urban roads.
