Abstract: The intended position and/or an intended alignment of at least one sensor for monitoring traffic at a traffic route is determined easily, quickly and reliably with the aid of computer technology. The methodology employed involves identification of a traffic route to be monitored in a data processing device, and requesting and providing data about the traffic route from a database. From this, at least one possible target position and/or target orientation is determined from the provided data. The methodology avoids the need to manually enter lanes and other local conditions of the traffic route. Instead, the data processing device recalls the required traffic data from a database, and based on manipulation of a graphical representation of the sensor by the user with the aid of the provided data and specified sensor characteristics an intended position and/or intended alignment of a sensor can be visualized and stored for later use during installation.

The device has a storage device and a computational device and an association module to calculate an association between a measurement and a track. The device further has an output module to output a sequence of track updates from an assignment module maintaining a set of active tracks using the association module as a function of active tracks and the incoming measurements to calculate associations, containing possible track updates and deciding which track updates to keep in the active tracks set and which to add to a passive tracks set. Computations on the passive tracks may be deferred until at least one passive track handling criterion is fulfilled. The computational device may activate and transfer a passive track from the passive set to the active set.
