Does changing road speed affect arrival time?

[ezerhoden]

I am curious if changing a roads speed limit has an effect on the ETA. Also does it effect routing? I am curious if these chages are considered by the routing engine or are these changes only noticed on the display of the unit.

I have noticed a difference since I updated to the new maps. The speed limits are appearing in the display. So far I haven't noticed route changes but the route calculation times are much closer. On a 45 minute trip I have out of 8 attempts (with traffic ant) I have not been more than 4-5 minutes off and have been spot on 2 or 3 times. Before I was always about 8-9 minutes early.

It takes the suggested road speed from th every point you are going FORWARD. However if you clock out a simple trip with a stopwatch VS the TT as you go you will see the time shift to sooner on the stopwatch than that which is displayed on the TT.

I'm seeing/experiencing similar results.

Very nice !! Since I can confidently call ahead to a company's recieving department giving them a reliable time of arrival of the freight i'm about to deliver.
