All of this data from TomTom has been supported by other mapping services, including Google Maps, but it was the only one offering real-time updates to its users.

By offering alternative routes to travellers, TomTom’s system also aims to help dissipate traffic jams more quickly by spreading out the journeys.

“Over 50% saturation you begin distributing traffic. It actually works better that way” she said, explaining that, if TomTom knows where your car will be going, it can re-route other drivers so they don’t get in your way, and vice versa.

“As you get more people using satnav you get better at distributing traffic, so not all users follow the same route” she said.

The theory is your TomTom won’t just calculate the fastest route using average road speeds, traffic congestion or even weather conditions – it’ll actually take into account other people’s journeys along the same stretch of road. This state of affairs just came one step closer as TomTom just signed a deal with Renault to install its GPS systems inside their new cars.
