TomTom Dynamic Routing
5 likes2,109 views
The document describes TomTom's dynamic routing technology which uses identical software both on-board in vehicles and off-board to continuously calculate and update the fastest routes based on real-time traffic conditions, finding better routes than traditional methods and saving users time on their journeys. It allows for fast replanning of routes, dynamic routing that searches for better options, and previewing the best route in advance using a "routing time machine".

Did you know that:
- Up to 15 alternative routes
between START & FINISH
- But People use/know only 1 or 2

![TomTom’s Challenge: To find the Best Route
amongst all Options for any Traffic Situation
Europe Map: 50 million crossings, 120 million roads….
and 800 sextillion (21 zeros) possible routes
All routes together consume space equal to 50 billion times the current size of the internet
Calculating all routes would take 25 trillion years
So finding the best route takes time …
but we’ve found a solution that is FAST & EXACT .
