Most maps when getting directions ask you for the parameters you want.
Fastest, scenic, coastal, stops, diversions, motor ways or not, Tolls or not, A roads, B roads etc.
Then the software works it out using the parameters you have stipulated.
I have family in Cornwall about 300 miles away. I tried out of curiosity mostly, different route scenarios and found that there was a three hour difference between the fastest and the slowest times although the distance was within a 30 mile + or - difference.What is the average driving speed for Google Maps directions?
What the other guy said.
It takes no note of anything other than the legal limit for roads; so whether that road is a bullet straight hard top or a twisty single track road they'll say, in the UK, that you will be driving at sixty.
This is fair enough, as to do it differently would be a bigger logistical nightmare than Streetview.What is the average driving speed for Google Maps directions?
It uses speed limits provided by our data providers,which generally get the information from road signs or public records.
