[SUPPORT] Routing doesn't consider Day of Week

Postby islupepa » Thu Mar 15, 2012 1:35 pm

Waze doesn't seem to consider time of day/night when calculating ETAs.
It should take less time to get to your destination when driving off peak hours than during rush hours.
At least if you drive in a city like São Paulo, with its 19 millions inhabitants.
I have an example where it shows that something is strange with the calculated ETAs. I have chosen to show the same route at different time of day/night to show my point.
The route goes from the airport straight into the "heart" of São Paulo.

It's really unrealistic that it should take the same time driving this route during off peak hours and during rush hours!!

This is probably just on the web live map?
Are you getting the same results on the client?

Unfortunately I get the same ETAs on the client!!
The route can change if there's any black, red or yellow marked traffic jam, but if there's not it will allways be the same route and the same ETAs. But from the description of Waze, it will know the average speed on every intersection at every time point of the day. We can see from the screenshots of this route that it's not working as intended!

Waze isn't going to consider time of day when calculating ETA, however, it's supposed to consider average speed of the segments on your route.

This was not working properly and was reported to Waze support a few weeks ago. I had a 15 mile route, and Waze was showing a drive-time of 18 minutes, but there was a couple of miles on the route that had an average speed of 2 MPH. Obviously, this should have added an hour to the ETA.

I think an announcement was recently made that it has been fixed, but I haven't had a chance to see if it's working now. Obviously not.

EDIT: I just sent a note to support referencing this thread.

Do you mean that Waze is not supposed to work like Tomtom's IQ route? It will calculate with the average speeds any hour of the day? This meens that Waze will overestimate the ETA during night and underestimate during rush hour!?

I'm pretty sure that Waze is supposed to give appropriate ETAs for the time of day (kinda the whole point of the app), but only if it has enough traffic data for local area.

On my routes waze uses the average speed for the time of day when calculating the ETA.

(I'm not sure how the widget would work otherwise.)

Does it work for you?

Yes, it generally seems to work for me. But I haven't turned waze on without being told that were at least 500 wazers near me (since that feature was added here), so its not entirely clear whether it is working because it is using good historic data for the time period, or whether waze actually has good realtime data for my routes.

I guess that my post has been read by Waze because something different is happening with the ETAs.
Right now I was verifying some routes and I saw that I could get much different ETAs within the same minute.
So back to the route I posted here.... Yes I could see the same behavior here.

2012-03-17 at 15.50 (local time), only ten seconds later

https://skydrive.live.com/?cid=1b307252 ... 201%211427

I did this a couple of times within the same minute and I could see these two results alternating.

You can try yourself by clicking this permalink...http://world.waze.com/livemap/?zoom=6&l ... g=61767782

Update a couple of times with the key F5 and you will see it alternating.

No color coded traffic jam on the route!!!
