Target architecture

The target architecture of our device is made up of three parts:

  1. The SpangBox, a standalone smart box, which analyses the situation and notifies the following vehicle

  2. The SpangApp on the user's phone which controls the SpangBox and manages information transit

  3. The SpangServer which receives and stores the anonymous information

Herewith a model of the SpangApp's landing page :

A validation model was built to prove the technical feasibility.

We are currently developing a prototype and we are looking for potential partners to industrialize a version that can be integrated into the majority of private vehicles.


In order to have a more accurate idea of how our innovation works, you can now view  an illustrative video of the latest version of our prototype

Technical analysis

These images display the current version of the real-time image analysis software in action. Through machine learning, it is able to analyse snapshots of the road and infer intra-vehicle distance. 

The SpangBox on the road

To keep track of vehicles behind a car (or any four-wheels vehicle), the SpangBox is placed on its rear window with a suction cup fixation system.​

To keep track of vehicles behind an electric scooter (or bike), the SpangBox is placed on the backpack of the rider with a clipping fixation system.​

Futurs developments

Spangbox on public and private buses​

In order to protect travellers, a SpangBox with an adjusted display can be placed at the back of a bus. ​This is especially relevant for school buses.
