Simplify an intersection 
Starting editors often tend to draw the map exactly like the satellite view shows. However, the Waze map should be as simple as possible, in a way that yield the best navigation instructions, with a clear and simple map on screen. This implies that sometimes roads or parts of roads are even not drawn, or drawn differently from the satellite view. As the examples show, when you draw the roads exactly like the actual situation (picture left) you will end up with lots of segments and junctions. This will result in a lot of maintenance, cluttered screen and database load. In addition, the driver receives many unnecessary navigation instructions that can be confusing. Simplified mapping (picture right) yields only one navigation instruction, with an easy and quickly readable map on a small screen.
