Your benefits when routing with NUNAV, the Koelnmesse app?

1. All you need to do is enter the event name as your destination.

2. You will be routed directly to an available trade fair car park located near your destination.

3. The app uses swarm intelligence to coordinate traffic flows. In this way, it can untangle traffic congestion before it occurs. This only works, however, if users follow the instructions provided to them.

4. We use your Bluetooth connection to enable trouble-free driving on the trade fair grounds.

5. The app is ad-free. Data are not stored.

6. The app is available free of charge.

If your parking space is located on the trade fair grounds, please activate Bluetooth on your smartphone, as this permits trouble-free driving on site.

We wish you a pleasant trip!

Rerouting during your trip

Unlike other navigation systems, NUNAV suggests a new route before a traffic jam materialises. This is how NUNAV can keep traffic flowing before the roads become crowded. The computation for this stems from an algorithm based on swarm intelligence. Thanks to rerouting, the user does not lose any time compared to those driving along the original route.

What about data protection?

NUNAV Navigation does not store any personal data. Use of the app is entirely ad-free.

The system only transmits and processes information about traffic – such as the roads a driver can use and the speeds at which speed it is possible to drive. To NUNAV, the sender of these data is an anonymous user who is irretrievably deleted every two minutes and then replaced by a new one.

In coordination with the City of Cologne, it is Koelnmesse – and not an ad-based software/algorithm – that manages the route taken to the right parking spaces and access roads.
