Huge journey time difference

[Tom Loder]

I plotted a c. 250 km route in Scotland on MRA and it gave me a time of 3 hrs 12 mins. The same route on Googlemaps comes up as 4 hrs 12 mins. A huge 30% increase !
What are other users experiences of the accuracy of MRA and Google maps driving times please?

@Tom-Loder There can indeed be differences in travel time. The route calculation is inherently different between Google and MRA (route engine). However, a one-hour difference does seem quite significant to me! Do you get these differences when you perform the route calculation, for example, using the TomTom map? Are you navigating based on a custom route with waypoints or an A-B route?

@Tom-Loder I usually find MRA times to be good. Are there roadworks showing on Google as Google will add the delay. MRA does not add a delay in the planner but will route around closed roads.

Does seem a lot as @Rob-Verhoeff says. Could you share the route? You will need to make the route ‘Public’ to do so.

I find the MRA calculation a bit too optimistic. I do not know how it is calculate, but in real-time you need to hurry to be in time.
In Norway for example, the average was quicker than the allowed max. 80km/h.

@Tom-Loder

Routes are not calculated based on applicable speeds but by a speed category (e.g. 30 zone = category 11-30 km/h - 50 zone = 31-50 km/h). But you may also have situations where your 100 km/h is allowed but practically cannot be achieved. It is therefore possible that in a 100 zone you may encounter - 61-80 km/h, which in turn affects the route calculations.

This was a custom route with 4 waypoints. There was a very small difference , less than 5km, in the measured difference of the two routes
