# Distance travelled

The distance that a vehicle travelled during a journey is captured by **myConnectedFleet** using one of two methods:

**CAN**

* This is the most accurate method with the OBU extracting the distance travelled from the vehicle’s CANbus. Read more about CANbus at [http://en.wikipedia.org/wiki/CAN\_bus](http://en.wikipedia.org/wiki/CAN_bus)

**GPS**

* During a journey, the telematics device calculates the distance between each GPS location and sums these distance values together to derive the total distance for the journey.
* This method is not as accurate as the distance obtained from the CANbus.
