We are currently updating the pages to include all regionally different guidelines. If you find inconsistencies, please refer to the English page. Thank you!

Real Time Closures (RTCs)

If a road is closed, we can map it using Real Time Closures or Partial Restrictions. A Real Time Closure (RTC) may be used when a segment is completely closed temporarily in one or both directions to all wazers. Examples are closures due to an accident, during an event, or to enable road works. RTCs are visible to the driver and can be removed in real time as well. For roads that have a structural and partial closure, such as during specific times or for specific vehicle types, we use Restrictions. Changes in restrictions need a map update and are not visible to the driver. This page deals with Real Time Closures (RTCs).

RTCs are used when a road is temporarily unavailable. From the moment an RTC is added, routing through these segments is prevented. Users are notified in real-time: active closures are immediately visible in the app and the Live map with alerts and candy stripes on the closed segments. WME shows RTCs with a red (active) or grey (planned) icon.

RTCs can be set by editors with Level 3 and above. The start date should be within the next 365 days, the end date and duration are unlimited.

When to use (and when not)

RTCs are used for closing off as well as opening up all traffic flow on certain road segments in real time. It can only be used when a road is completely closed in one or both directions, for all vehicles normally allowed.

If only one lane of a multi-lane road is closed, but traffic can still go in this direction using other lanes, RTCs should not be used. Waze will calculate the average traffic speed and automatically adjust its routing if possible.

For structurally closed segments with partial conditions, like during specific hours or for specific vehicles, RTCs should not be used. Instead, use Restrictions. Examples are closed routes during rush hours, or a route that is only suitable for motorcycles.

Permanent changes closing off a route, such as a road that changes to one-way driving direction, map it as such, and don't use any kind of closure.

Requests for closures

If you need to set or remove an RTC but the road segment is above your level or outside your editable area, you can always file a request. Requests for RTCs are welcome in the Slack closure channels: #30-vl_closures, #30-fr_fermetures, #30-bl_closures-bxl. With the script Send to Slack you can do this directly from WME. Non-Slack users may request closures on the forum.

Please provide following details in your request:

- Editor level
- City and optionally Street name
- Starting date and time / End date and time
- Closure reason / description
- A permalink of the segment to close
- Source of the closure information

Closures set in App

Drivers can mark an unexpected road closure while driving. Reliable requests become immediately active on the Waze map as an RTC . However, App closures are almost always defined in one-way direction with a limited duration, and they often need modification.

Therefore, closures from the App, together with information from several sources are automatically send to the relevant Slack-channels.

The date a closure is marked from the App is also the start date of the closure. To change the end date of an App closure: delete the App closure and create of a new one. More info on how to follow up these closures is described on the page about the closures bot.

Updating closed segments

It is not possible to modify some attributes of a closed segment.

The logical workaround (removing the closure and closing again after the update) will frequently fail, read next section.

Closing recently created/updated segments

It is not possible to close a recently created segment, until the segment is fully created by a map update.

Some recent changes do not allow closing a segment, or closing one direction of a segment, until the change is fully applied by a map update. In such a case, it is sometimes possible to create "short term" closures, expiring within the next 48 hours. As an example, after changing a two ways street into a one way street, it is possible to immediately close the forbidden direction, if the closure expires within the next 48 hours. Such “short term” closures can be extended later if necessary, if the end time remains within the next 48 hours.

It is not possible to close a deleted segment: it is not possible to apply closures from the "Current live map" view of the WME.

Multiple Closures for Events

For defining special events with multiple closures, see the Major Traffic Events page. Major Traffic Events, or MTE’s can be sport events (marathons, triathlons, etc), festivals, parades, significant construction works or even (natural) disasters like flooding, VIP visits, etc.

Automatic opening of a closure

If a certain amount of traffic passes through a road with an active RTC, it might disappear. This is checked about every 10 minutes. If traffic is detected only incidentally, the closure will return until the RTC s defined end time.

If the segment is paralleling another road in use, or needs to remain closed at all times until the given end time, even if movement is detected, mark the check box at HOV/Service Road adjacent (see picture).

Closing junctions

When adding an RTC to consecutive segments, all junction nodes in between those segments will be closed too. The nodes on the edges remain open.

If all RTCs on segments attached to a closed junction node are removed, the node closure will be automatically removed as well. However, if any segment attached to a closed junction node remains closed, the node closure will also remain.

How to work with node closures

1. Select the segments to be closed and fill in the details
2. Review the list of involved nodes at the bottom of the closure menu. Hoover over a node's cross-street name in the list of junction nodes in order to highlight that node on the map. When a node is closed, a symbol will appear on the map at that junction.
3. Enable and disable node closures as necessary, by flipping the switch.
4. Save the closures.

Remarks

• When closing two consecutive segments, the junction node in between will be closed too. This means that the entire junction will be closed for traffic. If you can cross that junction for any other route, make sure to remove the closure from the node. An open junction is shown as
• If you close two-way segments in just one direction, you will not be able to close the junction node.
• When removing an RTC from a segment that is connected to adjacent closed segments, the junction node will remain closed. You will then still see the closed node icon on the map. Traffic in any direction through this junction won't be possible. The same happens if you flip the switch on only one of the consecutive segments.

The above is also presented in this video tutorial made at the introduction of this feature.

Note: Prior to the introduction of node closures, the only way to prevent traffic crossing a closed street was to apply closures on the side streets as well. With the node closures feature, editing is more intuitive and easier and you'll have a better overview of the closed nodes.

• The Waze Closures Bot publishes RTCs reported via the app in the Slack BeLux Closure channels. Editors can easily use this data for modifying and implementing closures.
