Drive around with Waze
The easiest way to improve Waze is to drive around with the application running. Whenever you move through traffic without being navigated, turn on the Waze app!
You don't have to do anything. Waze uses the information it receives from you to calculate average speeds for the streets you drive on. It also shapes the appearance of the streets, and Waze learns the directions of the streets and the turns that exist in reality.
However, in order for Waze to automatically update the map, it would take a lot of routes traveled. The more you drive your routes with Waze, the sooner the map will adapt to your routes.
