Abnormal Load Transports

The transportation of goods with oversized dimensions. Abnormal load transports need to be registered and have to follow restrictions about trip routing and times.


An inertial sensor measuring the acceleration along a defined axis. Used in inertial navigation (IN) and dead reckoning (DR).


Collecting and listing liabilities and assets of business entities (in particular CDRs might be collected in large number of open item accounts).

Area Charging

A tolling scheme that establishes fees for the presence and/or activity within an area (including measured distances, stay times, etc.).

Assisted GPS (A-GPS)

A collection of methods to reduce the TTFF of GNSS-receivers by supplying additional information about satellite positions, etc.

Automatic Enforcement

An enforcement frontend system that produces pre qualified evidence records without on-the-spot human aid or interaction. (A downstream validation of the records by human agents might be necessary). Automatic enforcement systems can only check observable tariff parameters. Automatic enforcement consists at least of DSRC Communication and electronic means for recording and recognising a Vehicle's Registration Mark (licence plate)

Automatic Number Plate Recognition (ANPR)

Extraction of a vehicles’ licence plate number from a video image by the use of an optical system which automatically detect, read, and process vehicle's number plates. "Process" means to transform the content of the picture taken from the number plate into a digital manageable form, e. g. into a text string of a program language. (Possibly including a vehicle type classification and speed measurement).

Automatic Scheme

The automatic scheme is based on a combination of mobile telecommunications technology and satellite-based Global Positioning System.
