Telematic control for HGV parking motorway 2 at Börde, Germany
13 September 2011 - The project at the service area Börde in driving direction Berlin is one of three pilot projects at motorway 2 concernded with the telematic control for HGV parking with different detection methods. Besides one already existing installation using geomagnetic field sensors and a planned system based on video technology, the installation at Börde is to test the usage of intelligent loops.
All three methods are to prove their applicability to be used at service and rest areas with HGV parking.
Objective is to reliably determine the actual occupancy of the parking spaces (error rate below 10%) and to neglect the vehicles leaving the parking area without parking.
The project consists mainly of the detection, evaluation and transmission of traffic data with:
Nine detection points with inductive loops in the lanes determine the occupancy rate of the parking spaces. The passing curves are evaluated by means of a special algorithm. With this, the entering and leaving vehicles can be compared and matched.
By means of the protocol TLS-over-IP, the vehicle characteristics determined by the algorithm are forwarded as unique IDs to the parking management center. There, the free spaces are evaluated by calculating the entering and leaving vehicles, not tracking individual vehicles but counting similar vehicle patterns. The number of spaces is then forwarded to the display sign in LED technology.
The system uses a detector newly developed for this application with special software. Here, our team of developers benefitted from the Weiss-Electronic detection know-how.
A particular challenge in this project is - in contrast to the application on motorways and interurban roads - that all kinds of traffic conditions such as sudden speed changes, stop and go traffic, manoeuvrering and reversing vehicles must be considered. Thus, before even starting the first comparitive measurements on location, extensive tests were executed in Trier with a true to scale model of the parking area. The model was equipped with the according miniature loops and rc-models of cars, vans and HGVs were modified in such way, so that they would give out realistic passing curves. Thus, at an early stage already, many particularities could be detected and cleared.
After the receipt of orders in mid August, the final planning documents were created and approved at the beginning of September. The pilot installation is currently being implemented and is planned to start with test operation in October.

The project consists mainly of the detection, evaluation and transmission of traffic data with:
- detecting and adding up the number of HGVs in the parking spaces by means of loops
- two video cameras used for traffic monitoring, for supporting the winter service, for supporting the police fighting crime as well as for monitoring the system functions and accuracy of the display
- one LED-sign displaying the number of free parking spaces
