Last year, Apple, along with the announcement of iOS 13, demonstrated the new Apple Maps feature – displaying traffic lights and Stop signs on the map. This feature provides drivers with more navigation information. For example, before a trip, you can compare two similar routes, on which of them there will be more traffic lights.
One of the users of Google Maps discovered a similar innovation in this application. Traffic lights began to be displayed, both in normal map viewing mode and during navigation. Small traffic light icons are not very easy to recognize right away, but they get bigger in navigation mode.
Most likely, while Google is testing a new feature among a limited number of users. It is reported that she earned on the version of Google Maps 10.44.3. However, I did not find any traffic lights on the maps in the same version of the application.
