Does VROOM retrieve route and duration from Valhalla based on historical traffic data?

Does VROOM retrieve route and duration from Valhalla based on historical traffic data? i create graph of valhalla with historical traffic.

For example, if a job starts at 6 AM and takes until 9 PM to complete, does vroom get routes from Valhalla dynamically and calculate the next route’s duration based on the estimated completion time of the previous route? In other words, does each subsequent route consider the updated start time based on when the previous route finishes?

No, this would mean waiting for a full routing computation each time we need to evaluate possible trip options which would be prohibitively too expensive.

What happens is that we first fetch matrices for all travel times and distances between all locations involved in the problem, then re-use that throughout the optimization phase.

Consequently, the travel times that are used are static, meaning they do not account for time of day information. We'll simply pick whatever values are returned by your routing engine a priori.
