I am currently using this VBA-Code, written by Jamie Bull, to calculate both, driving distance, as well as driving duration, between approx. 1.500 villages and a specific shopping center, using excel.

Google shows me the driving time for each trip, considering the current traffic situation. But I only need a kind of average driving time or the driving time without traffic situation, in order to be able to compare the driving times for each rout all else being equal.

Using the google Maps website, I can see several driving times: Current time and time without traffic. Is there a way to integrate this into the code?

By the way: Are there any information about, which driving speed is used for calculating the driving time (without traffic)?
