Method and apparatus for the generation of early warnings of traffic collapse at constrictions

The invention relates to a method for the generation of early warnings of traffic breakdowns, comprising the steps of: - estimating the dynamic capacity of constrictions in the road network, - Determine the current demand at bottlenecks, - determining the anticipated demand for a selectable forecast horizon - triggering early warnings as soon as the situation resulting from expected demand and dynamic capacity breakdown probability a limit value, the warning threshold exceeds, - Measurement of indicators to assess the quality of information from early warning as a function of process parameters of the Early Warning System, - creating an operating characteristic of the early warning, - tailor the early warning system on the quality requirements of an application by drawing on the work characteristic of the early warning system.
