Real time closures (RTC)

Return to the editing manual [Return to the editing manual] [image] A Real Time Closure (RTC) may be used when a segment is completely closed temporarily in one or both directions to all wazers. When the RTC is active, the affected segment will be marked with red-and-white candy stripes and Waze will not route any traffic through or onto the segment. Only use an RTC when a road is completely closed in one or both directions. Do not use an RTC for lane closures, width restrictions or other cases where traffic is still allowed to move. The real time closure is the preferred method for temporarily closing roads because it is visible to Wazers and because it helps protect the map. Deciding when to use an RTC There are several possible ways to prevent Waze from routing traffic over a segment. The best choice depends on the situation. Method Vehicles Affected Takes Effect Ends Traffic Data Guidance Real time closure All Immediate Expires Kept Preferred option for temporary (even long term) one-way or two-way closure. Visible to drivers. Immediate effect. Automatically removed when it expires. Road direction change All Tile update Permanent Kept Use only for permanent change in direction from two-way to one-way. Time-based segment restriction Some/All Tile update Optionally expires Kept Use only where the restrictions (time of day/ day of week) are permanent, or where certain vehicle types are allowed or prohibited. Example: No passenger cars on weekdays. Time-based turn restriction Some/All Tile update Optionally expires Kept Use where travel on the segment is allowed, but turns onto the segment are temporarily forbidden or else permanently forbidden at certain times of day, days of week or for certain vehicle types. Example: No left turn 4:00pm-6:00pm Permanent turn restriction All Tile update Permanent Kept [image] Use where a turn onto the segment should be permanently forbidden for all vehicles. Conversion to a penalized road type All Tile update Permanent Kept Penalties make routing less likely, but are not absolute. Vehicles with a destination on the segment will be routed onto the segment. Normally  Private Road  is used. Disconnection All Tile update Permanent Lost Use only if the disconnection is permanent. All turn data is lost. Deletion All Tile update Permanent Lost Use only if the road is permanently closed. All data is lost. [image] Real time closures are the preferred way of temporarily controlling traffic for a number of reasons They begin to affect routing within a few minutes of being saved, without waiting for a tile update. When the RTC is removed, proper routing can be restored immediately, without waiting for a tile update. They allow editors to temporarily prevent routing over specific segments, without having to make any changes to, or damage those segments, and their road types, junctions, or turn restrictions. They preserve traffic data. By default (see below), a road closed with an RTC will be continually evaluated for through traffic. If enough traffic is detected driving through a closure, the closure is temporarily deactivated until the traffic is no longer detected. Therefore if an RTC is mistakenly placed on an open segment it will only affect drivers for a few minutes until the through traffic is detected, and the closure deactivated automatically. Real time closures are visible in Live Map and the Waze app with special alert icons and segment highlighting. They are also visible in WME with special icons. They can be created and commented on within the Waze app, with app creations and comments generating notifications for editors. They can be associated with Traffic Events to get notifications sent to nearby Wazers. They eliminate the need for addition and removal of partial restrictions. In fact, partial restrictions should not be used redundantly with real time closures Effect on routing [image] Waze will not choose a closed segment as the closest segment to the destination. When a real time closure is active, Waze will not route through or even partway through the closed segment in the direction(s) it is closed. It will not route to a destination on the closed segment(s), even if that is the closest segment to the destination. Instead, it will pick a stop point on the next closest segment. If the closed segment is much longer than the part of the road that is actually closed to all traffic, this can result in wazers being sent to a nearby street even though they should be able to drive to the destination.
