Abstract
There is described a method and a device for automatically generating traffic management strategies in the event of suddenly occurring traffic events that lead to a disruption in the flow of traffic. During the method, a database is used in which information concerning elements of the influencing of traffic and control of traffic, which exist in the traffic network, local positions of the elements, switching states that can be adopted by the elements, and immediate effects of the respective switching states upon the traffic is contained in a form that can be processed by a computer program. Based on the incoming data concerning the traffic events or disruptions in the flow of traffic as well as an actual traffic situation, a simulation is automatically carried out with an analysis program, during which dynamics of the spread of the disruption in the traffic network are modeled and one or more new traffic-optimal route allocations with capacity values required therefore are calculated. A generation program selects from the database the elements that can make a contribution to the conversion of the new route allocation, and automatically parameterizes these elements using the adoptable switching states and their effect. The selected elements and their parameterization are suggested to an operator as a strategy. The method and the associated device make possible a quick reaction to unforeseeable events in the traffic network.
