google maps
I am using Google Maps to determine my route to work. It is about an hour currently, but I know that when I factor in traffic it will be longer. I want to know just how much longer it will be.
I was wondering if there is a way to use the past traffic delays to calculate what my travel time might be given a specific travel time for that day?

The trick is in the ?layer=t query string ;)
New Maps
Head to new Google Maps and go to where you want to view traffic.
Clear the search box (yeah, the UX people were out that day).
Hover your mouse over the search area and underneath "Getting around" should appear with some options. Select "Traffic":
You can then select "Typical Traffic" and change the date/time of the traffic you are looking at:
Check out the map and try some different routes - avoid the red bits!
Old Maps
Head to old Google Maps and select your start and finish points as usual. Then select 'Traffic' from the dropdown at the top right:
You should then get a menu on the lower left of the map that allows you to change the date/time of the traffic you are looking at:
Check out the map and try some different routes - avoid the red and black bits!
Best Answer
If you hover over the directions box (top-left) on the map, you will see that it tells you the estimated time for leaving now.
If you click on the "Leave Now" part, you can change the departure or arrival time. When you do, you will see the estimated time update to take into account known traffic flows for that date/time.
That's as good as it gets since those kinds of calculations are highly complex and based on all sorts of factors including road works and average traffic flows.
