This article covers the automated map Problem reports and appear in the Waze Map Editor as a colored balloon with a white exclamation mark.
Overview
Map Problem is comes from the Waze system when it detects something that is happening in the real world as tracked by the Waze client apps that does not match the logic in the map data. There are two options the editor can use to respond to these Map Problems: Mark as Solved, Mark as Not identified. Just because you do not know the solution doesn't mean that another editor won't figure it out, so do not use Not Identified to mean that you alone cannot identify the problem as this closes the problem for all editors.
Interface Elements
The color of the problem balloon, just like Update Requests, are indicative of something. In the case of Problems, it is the number of drivers affected by, or driving through the problem area, in an unexpected manner. The more drive traces which follow the same route, the higher the likelihood that this problem needs to be fixed. An exclamation point in the icon shows that the problem is open and the color indicates how many drivers have gone through that area with that problem.
A yellow problem balloon has been generated by 1-3 drives.
An orange problem balloon has been generated by 4-7 drives.
A red problem balloon has been generated by 8 or more drives.
The Problem changes to this icon when you "Mark as Not identified". If a Problem is "Mark as Not identified", Waze will not show it again in that location, so "Mark as Not identified" only if you are certain that there is not actually a problem there.
