Automatic map updates and the locking of roads

From waze

Waze looks at driving routes and makes adjustments to the map. It will change the directionality of a road, enable turns, and reportedly it will change the geometry or layout of a road.

This can cause map errors, especially in areas where there are few wazers. One wazer who always travels one way down a road may change a correctly recorded two-way road into one-way.

Some roads are restricted to one way during normal driving hours. Some late night driving may change these roads to two-way causing problems when people try to use that route during the day. Other roads have turn restrictions that apply at peak times. Waze may enable a restricted turn causing bad routing advice at peak times.

If you observe this, the solution is to correct the road and then to tick the Locked checkbox on the Edit Map Details screen, making sure to Save Your Changes.

A Locked road segment will not change its directionality or geometry. It also makes it unlikely to make changes to the connections on the road junctions at each end. If it is the junction turns that you wish to lock, lock all road segments that connect to that junction.

Locking a road segment will prevent lower users from changing it only if it is close to their driving area. If they are area managers at this location, they can still edit the segment.
