Definitions

  • the invention relates to a method and apparatus for merging traffic data with incomplete information, taking into account information from different sources mapped to functions to obtain a result based on calculations with these functions.
  • the object of the present invention is to overcome the aforementioned disadvantages of the prior art.
  • it is a method for local determination of traffic situation data, taking into account a plurality of traffic reports with fuzzy location information, which are to be merged as best as possible. It includes the following steps.
  • Fig. 1 shows a schematic representation of an inaccurate traffic information source which reports a disturbance of length L between the terminals AS1 and AS4;
  • Fig. 2 is a schematic representation of the data fusion, with the result of the data fusion displayed at the top, in the middle of which the message from the inaccurate source and the local numerical traffic situation data are displayed;
  • the present invention report deals with an optimal solution of the data fusion problem with incomplete information.
  • n (x) For each possible position x within the allowed value range, a function n (x) is determined which indicates the proportion of the reported disturbance that can not be refuted by existing traffic situation data
  • the weighting factors gx can be determined on the basis of a priori knowledge about the quality of a source. For example, disturbances reported by the police are locally blurred i.d.R. credible and try to confirm them; however, police reports are usually not timely deregistered. Further criteria for the gx are the (origin) position of disturbances (disturbances arise at bottlenecks, therefore they are preferably positioned as far downstream as possible) and quality requirements for the end product (eg correctness could be more important than completeness, then the confirmation gb would have to be heavily weighted ). By statistically evaluating the distribution among the categories "acknowledgment,” "ignorance,” and "refutation,” the assumptions made to set the weights may be reviewed and it may not be possible. an adaptation takes place.
  • the kvm indicate the locations of the connection points.
  • L the length of the possible error.
  • fusion with the local numerical traffic data is performed as follows. Wherever the sharply localized message competes with non-knowledge from the traffic assessment, the relevant share of the message is adopted as the end product. In all other places, the numerical traffic situation data is preferred.
  • Fig. 2 and Fig. 3 shows a traffic incident that occurred on 10.01.2005 due to an accident on the A555 from Cologne to Bonn shortly after the junction Bornheim / Alfter ( ⁇ km 16). From direct observation it was known that the traffic disruption was in the range of km 13 - 17. There is no stationary measurement infrastructure in this area.
