Definitions

  • the invention relates to a method for determining traffic situation information within a transport network using mobile detectors, in particular Vehicles of a sample fleet, which have a terminal, a center for Determination of traffic situation information within a traffic network, the at least from a mobile detector receives data of its geographical position, a Terminal in a mobile detector, the at least one Positioning device includes or is connected to this, and a Data processing device and a device for data exchange with the Central includes, as well as a software program product directly into an internal Memory of a central office and / or the terminal of a mobile detector can be loaded.

  • Another task consists of identifying information for traffic and road network planning.
  • the German patent application DE 195 21 919 A1 proposes a method for determining traffic situation information in which the detected vehicle and position data are already assigned in the vehicle operating as a detector to at least one predetermined class of vehicle and position data corresponding to a specific typical vehicle behavior become. These classes are called vehicle behavior patterns.
  • the assigned vehicle behavior pattern is transferred with the position data of the vehicle at least partially in coded form to the traffic control center.
  • the terminal then located in the evaluation state t 0 now checks the detected speed values in comparison to the limit speed and interprets after passing through a time t 0 + t 1 the traffic condition on the route section as a total traffic disturbance when the mobile detector is driven at a lower speed than the deposited limit speed. If the terminal analyzed a traffic status as disturbed, a corresponding data telegram is generated and transmitted to the traffic center via a mobile radio network.
  • the disadvantage of the previously known methods lies in the fact that a large number is generated by incorrect and / or non-relevant messages, in particular longer stops before traffic lights, barriers, etc. in the inner city area as well as braking operations before passing through towns are recognized as traffic disruptions and passed on to the customer.
