Zaragoza

This summer I'll drive to Galicia. Barcelona La Coruña. Looking at Google Maps, I calculated a route and gave me an estimate of the number of hours it would take to arrive.

How reliable is this estimate? Anyone who has driven thinking is that there are many factors that can spoil the estimate. A jam, an accident resulting in retention, road cuts or road works.

Apart from these details, on the road (or highway), there are other drivers. And that keeps me from going to the speed of the track, because as I have to pass him, and until I can, I go slow.

O is joining somebody, I I can not change lanes, and I have to stop a bit to let him. Nor should it be a bastard right? You brake a little and he has to stop right in the acceleration lane. Well

. As I was saying. What time deviation between the calculated route that Google Maps, and made the same trip by car?

The tour will be this:

tour


According to Google Maps are 305 km and would take 2 hours and 48 minutes.

I came from Barcelona at 17:40. And I got to that point (near Pilar de Zaragoza) at 20:50. Therefore, it took 3 hours and 10 minutes. 22 minutes more than estimated by Google. We could say that about 8 minutos más por cada hora de viaje.

¿Y la vuelta? Del mismo punto de Zaragoza (Pilar) salí a las 0:35. Y llegué a Barcelona a las 3:40 (a ese punto de Ronda de Dalt). Pero en el viaje de vuelta me paré a repostar. Unos 15 minutos.

Por tanto, el viaje real fue de 3 horas y 25 minutos. El Google Maps marca 2 horas y 48 minutos. Unos 37 minutos más. En este caso, unos 12 minutos más por cada hora.


Añadir que el viaje de ida lo hice por la tarde (salí a las 17:40) y el de vuelta de madrugada (salí a las 0:35). En la ida, además, tuve que coger un desvió de unos 10 Km porque había obras en la A-2.


En resumen.

Not that this is a calculation based on statistical rules, but only experimental, I would say that for every hour that marks the Google Maps, I need to add between 8 and 12 minutes a time marked by Google.

an example.

If I want to go from Barcelona to Seville, the Google Maps brand me 10 hours and 21 minutes. If every hour I had 12 minutes, would add 10 * 12 = 120 minutes or two hours.

Therefore, from Barcelona to Seville, respecting speed limits, it would take 12 hours to arrive. :-)
