Notification window at certain time with traffic jams from work to home Wow, today I saw a great window.

This is a notifier from google maps or apple maps that shows me a way to home from work at certain time (when I usually go home) with traffic jam.

Does anybody know what is it and which app / service show me that window?

I suppose that it can be a google chrome plugin or apple os x service. Not sure
This sounds like the Google Now feature.  If you have chrome installed and running, you can click the alarm-bell-like icon in your menu bar to configure it.
From Google's support page:

How Google Now works in Chrome
If you use Google Now on your mobile device, you can see certain Now
cards on your desktop computer if you're signed into Chrome, including
weather, sports scores, commute traffic, and event reminders cards.
Some of these cards may be based on the location of your mobile
device. Learn how to sign into Chrome
To see these cards, open the Chrome Notifications Center by clicking
the bell icon  in the system tray on the lower right corner of your
computer screen (on Windows) or in the menu bar on the upper right of
your computer screen (on Mac).

Emphasis added.
Below is a screen shot showing where the bell is on my menubar (YMMV).
