| 摘要 |
The invention relates to a method for monitoring the condition of traffic in a traffic network comprising effective narrow points during which the condition of traffic is classified into one or more condition phases based on recorded traffic measurement data of one or more traffic parameters, which at least comprise information concerning the traffic density and/or the average vehicle speed. Said condition phases at least comprise the condition phases of free traffic and synchronized traffic. The invention provides that, during the occurrence of an edge which is fixed at an effective narrow point and which is located between downstream flowing free traffic and upstream flowing synchronized traffic, the condition of traffic, upstream therefrom, is classified as a model of dense traffic that is representative of the respective narrow point. Said model contains one or more different regions of a different condition phase composition which is/are successive in an upstream direction, and contains an accompanying profile of the traffic parameters that are used for determining the condition phase. The invention also relates to the use of the inventive method, for example, for monitoring the condition of traffic and for projecting the traffic condition in a road network.
