GPS signals are often very inaccurate, which can lead to individual GPS points being outside the route actually travelled. This, in turn, complicates precise route tracking and accurate projection of the route on a digital map. However, highly precise tracking data is required for a large number of applications:
PTV components can match GPS signals (tracks) with the underlying map. So-called map matching has a built-in logic which enables it to recognise the driving direction, lane and speed, etc. on the basis of the route previously driven. Inaccurate positioning data can therefore be corrected, resulting in precision in the recording of the route, which cannot be achieved with unmatched GPS signals.
