The importance of Trajectory Checks
and the impact on our society.

Smart cameras store a huge amount of data every minute. Originally this data comes in as one big mess, but put a decent back-office system behind it and what do you get as a result? Indeed, an enormous amount of metadata.

I'm sure many of you will know what we're talking about when we drop the word "metadata", others amongst you will probably shout out loud "meta-what?".

To put it very simply, metadata is data that describes a huge amount of data. In this specific example, metadata can be license plates, the type of cars or the colour of the cars.

Trajectory checks & their impact

In Belgium there is a series of route checks throughout the country. An ANPR (Automated Number Plate Recognition) camera is placed at the beginning and the end of this distance for over approximately 4 or 5 kilometres. If you drive too fast, this will be recorded by these cameras.

Research done by Macq & PoliVisu has shown that 2 years after the start of the route checks, there are up to 4 times less speeding violations within the given distance.

A general analysis of a large number of route checks within a 70 km/h zone shows a clear decrease in the number of overspeeding drivers & fined offenders. In the long term there are 8% speeding drivers in the beginning, with only 2% remaining at the end of the study. If, on the other hand, we look at mid-2017 and mid-2018, we can see a brief increase in the number of offences. This has to do with the installation and commissioning after homologation of a series of new average speed measurement areas.


Behind the scenes of the ANPR-camera

A single ANPR camera records millions of vehicles every year. Number plate recording occurs when a vehicle passes in the field of view of an ANPR camera and that camera is able to read the license plate clearly.

You can imagine that a smart camera is not only able to read license plates. Everything that is recorded on screen is readable. All that is needed is a good back-office system. A back-office provides the possibility to convert all data recorded by the camera to metadata. Such as reading license plates, detecting who is over-taking a car when prohibited, which is driving too fast in a certain zone, which is driving through a red light, you name it. There are therefore many possibilities with the same data.
