|Do NOT use any of the tools discussed on this page for lane closures. These methods of controlling traffic flow are only to be used when a segment is completely closed in one or both directions to all public through traffic temporarily.|
Roads on the map often need to be closed for a variety of reasons; ranging from planned construction or a large-scale event, to emergency closures for accidents or natural disasters. These are called Real-Time Closures, and will be discussed in detail on this page.

Controlling traffic flow
There are several mechanisms to prevent Waze from routing traffic over specific roads. The method used depends on the reason traffic flow needs to be prevented. Here is a brief overview of the various mechanisms available for controlling traffic flow on specific roads. For specific details on any of these mechanisms, please see the corresponding wiki pages linked below.
- Real time closures (this page) — Should be used when a road is temporarily unusable, but does not need modification (including turn restrictions). These display in the client and Livemap with alerts and candy stripes on the segments to notify users of the closures in real-time (no wait for tile updates), and prevent routing during the closure time on these segments. Due to its safety (protecting the map), and its visibility (in the client and Livemap), this is the preferred method of closing a road.
Real-Time Closures can be submitted in a variety of methods, discussed in detail further on this page:
- Partial restrictions (AKA Scheduled or Time-Based Restrictions) - Used when turns or roadways are restricted at certain times of day, days of the week, vehicle types, etc. These have the ability to only restrict during a specific date range, but should NOT be used in place of Mega Traffic Events or Real-Time Road Closures.
- Road types — Certain road types (Private, Parking Lot Road, Dirt Road/4X4 Trail) will automatically prevent routing and should be used when appropriate for permanent situations.
- Disconnect road segments — Road segments should only be physically disconnected if the road is no longer intended to connect or is being permanently removed. When a road is disconnected it becomes absolutely unroutable, and all stored speed data for the junctions are lost. This should be done with the support of a senior editor. In the past, this method was used for longer term construction projects, but now the Road Closure feature should be used.
Real time closures
This is the preferred method for closing roads due to its safety and visibility to Wazers.
The editing community can be informed about these closures by:
- URs/MPs submitted through the app
- Knowledge of local happenings
- Notification from the local community / Waze Major Traffic Event Team
- Long term closures
All Real-Time Closures follow the same general principles below, regardless of which method is used to submit them. Depending on which method is used there are additional guidance and instructions in the corresponding unique subsections below.
Real Time Closures can be added to Waze in four ways:
- Report a Closure in the Waze client app
- Major Traffic Events (MTEs)
- Temporary Closures in WME
- Closure Sheets
As mentioned above, if the closure is part of an event which will be impacting a large number of people in your area (i.e. - major highway closed, city-wide marathon, natural disaster) please be sure to submit the MTE form first.
Safety and visibility
This feature is safer than other methods of controlling traffic flow for a number of reasons.
- It allows 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.
- The history of the segment is preserved.
- When the RTC is removed, proper routing can be restored immediately, without waiting for a tile update.
- 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 Livemap, and the Waze app with special alert icons, and segment highlighting. They are also visible in WME with special icons.
General closure guidance
This slideshow was prepared by Waze staff to show how to add a closure in WME. It contains information on which segments to select as part of a closure as well. The information in this slide show is also presented throughout this page in text.
Real time closures vs. partial restrictions
Many major roads have ongoing restrictions, which are based on day of the week or time of day. Some examples include:
- No Left Turn between 12:00pm-6:00pm
- No passenger cars on weekdays
For these types of restrictions, please see the Partial Restrictions page on the Wiki.
If a road is closed with a Real Time Closure, there is no need to duplicate the Closure with an additional Partial Restriction (AKA Time-Based Restriction) for traveling across the segment, or change any turn restrictions. (This also helps preserve the map, as soon as the Temporary Closure expires, or is cancelled, the map will route as it's supposed to.)
Usernames and closures
Adding a Temporary Closure does not put your name as the last editor for the segment (Updated By: user (#)), however you can see who added a closure by looking at the alert in livemap or the client.
Junctions and cross traffic
When adding a Real-Time Closure consider whether any cross traffic will be blocked as well.
- If traffic going across your Real-Time Closure at a junction must be blocked as well, you will need to close one of the cross street segments as well.
- You should close the segment leading away from the main road with the Real-Time Closure.
- If the cross street is a two way street, close only the shorter segment.
- When closing a two way cross street segment, only set the Real-Time Closure to the direction leading away from the Temporary Closure.

Lane closures and construction zones
For situations where only some lanes are closed but the road is still driveable, and general road construction situations, refer to that article for additional specific information.
DO NOT use Real-Time Closures for roads which only have some lanes closed.
Web based closure guidance
Dates and times
All Real-Time Closures are set using the ISO-8601 "extended format".
Put simply this means whenever entering a date, it should be in the format of YYYY-MM-DD. The YYYY is the four digit year, MM is the two digit month, and DD is the two digit day of the month. (For example March 15th, 2015 would be entered as 2015-03-15.)
Whenever entering a time, it should be using the 24 hour clock, in the format of HH:MM:SS. The HH is the two digit hour, MM is the two digit minute, and SS is the two digit seconds. The seconds may be optional depending on the feature you are using. (For example 2:53 pm will be entered as 14:53.)
In the 24 hour clock, the first 12 hours of the day from midnight until 11:59 am, are represented as 00:00 - 11:59. The second twelve hours of the day from noon until 11:59 pm, are represented as 12:00 - 23:59. To make it easy to remember, any time in the AM hours, is just the same (with a leading zero for the first nine single digit hours). Any time in the PM hours, add 12 to the hour (so 2 pm becomes 14 - 2+12=14).
The minute of midnight can be represented both as 00:00, and as 24:00 depending on if it is connected to the previous day (24:00), or the new day just beginning (00:00). For example Monday 24:00 is the same minute as Tuesday 00:00. To prevent confusion you should avoid using 00:00, or 24:00 as a closure time, instead use 23:59, or 00:01.
Start and end time settings
|Be careful choosing closure times. 00:00 is the first minute of a day, 23:59 is the last minute of a day. A closure ending on Jan 1st at 00:00 will leave the road open for the entire day of Jan 1st, while 23:59 would leave the road closed for that entire day. To prevent ambiguity try using 00:01 instead of 00:00 as a closure time.|
- Real-time Closures are active for the full minute they are set for.
- A Closure set for Start: 03:00 - End: 03:01, will actually be closed for 119 seconds, from 03:00:00 - 03:01:59.
- A closure set for Start: 03:00, End: 04:00, will actually be closed for 60 minutes and 59 seconds, from 03:00:00 - 04:00:59.
All times entered are in the local time zone of the segment being closed. If you are in one time zone, and are submitting a closure for a segment in another time zone, use the start and end times in the time zone where the segment is.
Setting long-term closures
NOTE: Temporary Closures must not be longer than 6 calendar months (183 days to be precise).
To enter a Temporary Closure longer than 6 months, split it into multiple Temporary Closures. Each Temporary Closure entered should be less than 6 months. E.g. A one year Temporary Closure from 2014-12-01 through 2015-11-30 can be entered as two individual Temporary Closures.
- 2014-12-01 - 2015-05-31 (182 days)
- 2015-06-01 - 2015-11-30 (183 days)
Report closure feature in the Waze app
Users in the client app can mark an unexpected road closure they see while driving. It is typically used for unexpected, short term closures of up to a few days. This feature requires multiple users to be at the location to enter the same road closure information on the map before it will be seen by other drivers.
Instructions on how to use this feature in the Waze app is available in the Waze Help Center.
App reported closures in WME
Any closures reported from the Waze app are visible, and can be manipulated in the Waze Map Editor. Waze app reported closures do have an effect on routing until enough user report the same segment closed. However if an editor sees it in WME and edits it, they can they take effect immediately. For all the details on the display and handling of app-reported closures in WME please see the section below that explains the WME aspect of these closures.
Major traffic events
If a road closure is part of a larger event, it can be submitted to Waze as a Major Traffic Event, or MTE. MTEs are generally determined by the scale of the event and how many people will be impacted. The closures should be submitted using the MTE sheets provided. This way Waze is able to track the closures and help spread the word.
To receive further support from Waze (website and/or push + inbox message) for a closure, the event must be submitted through the MTE submission form below.
To notify Waze of a coming event in your area, use the MTE Submission Form. Helpful information to have for submissions are as follows:
- Name of Event
- Website for event
- Roads which will be effected (not necessary)
- Start and End Date
- Start and End Time (if available)
All MTE submissions are posted to the Waze Mini Site (if the mini site gives an error try refreshing the page) so that other editors in your area can find the name for an event and mark the closure consistently.
The closures for each MTE are submitted in a unique Google Sheets spreadsheet. If you need access to a particular event spreadsheet, request access in the spreadsheet and it will be granted by Waze HQ.
Support for major traffic events
Once the submitted event is reviewed, the submitter receives an MTE closure sheet and further instruction on how to provide all of the information needed to properly close the effected roads.
Once the closure sheet is fully completed, the closure will be live in the app.
Waze further supports some MTEs by providing local push notifications, inbox messages, social media announcements and/or website features on the Major Events page on Waze.com.
MTEs are likely to be announced on the Major Events website and/or via inbox + push message if the event effects a significant portion of the local population. For your event to be considered for inclusion in the following weeks push/inbox messaging, all closure information must be received by Wednesday prior.
A closure may not appear in the app if Waze is unable to obtain the proper information, either through user-completed closure sheets or if other resources cannot be found.
WME closure feature
This is the preferred method for closing roads due to its safety and visibility to Wazers. The feature allows editors to temporarily prevent routing over specific segments, without having to make any changes to, or damage those segments and their junctions.
With this tool, closures can be entered directly in WME, and is visible almost immediately in the client and Livemap. It is displayed prominently on the map as a closure alert, and with red and white candy stripe lines along the closed segments.
Closure feature permissions
This feature is restricted to rank 5 editors and above, unless otherwise decided by the local community. Global champs also have the ability to allow users of various levels access to the feature. If you would like to request access, contact a member of the community in the Waze Community Forums.
Alternatively, If you do not have the required rank to access the Closure feature in WME, you can ask a higher ranking editor to implement the closures for you. Your country may have a streamlined monitored process for this, or it can be submitted like any other unlock/update request. You can also ask a higher editor directly in a PM, or WME Chat. In the USA the Road Closures Form (USA) is used for example.
Step by step instructions to add a closure
- Select the segments you want to close.
- Click the Add Closure button in the left panel.
- Click to + Add Closure and fill out the fields shown:
- Location - This field will auto-populate to name of affected street. If multiple streets are selected, add a general description of the area (name of the road, the interchange, or the area if several roads in a known area are being closed). This section is NOT view-able in the client app, it is only seen in the WME.
- Reason - This section will be view-able in both the client app and the LiveMap. Write a description of closure / event here. Once supported, #hashtags will go here.
- Direction - Closure direction should be noted carefully (using the A and B nodes for reference). Close one way direction on a two way road here.
- Event - This field is not currently active, please ignore.
- Start/End Date & Time - Enter date/time the closure will remain active (the start date can be a date in the past). Enter local time for area of map you are editing. Format is 24-hour clock and YYYY-MM-DD. NOTE: End date can not be more than 183 days after the start date. (see below for more information.)
Saving your work
Save & Check in the live map. Active closures will appear with red closure icons in WME, and with closure alerts bubbles and red and white (candy stripe) road segment highlighting in Livemap immediately.
Inactive closures will appear with grey closure icons in WME only. They do not appear at all in Livemap or the Waze app.
A closure can not be entered along with any other saves, similar to House Numbers. If you have any edits pending a save, and try to add a Temporary Closure you will get an error at the end. Be sure to save before trying to add a Temporary Closure.
WME closure feature guidance
Closing recently edited segments
Real-Time Closures entered using this feature are not subject to waiting for a tile update, they will go live almost immediately. However, since the Real-Time Closures are effected on the segments and nodes as they are now in the current live map, they don't work on segments and nodes which are not already included in the current tile build. If you enter a Real-Time Closure for a segment which has been modified enough (e.g. changed the segment ID, node ID, or junction location) since the last tile update, the Real-Time Closure would be corrupted and not functioning properly until after the next tile update.
To protect against this, if you try to close a new or modified segment before the tiles update, the closure will not save and WME will display an error (!) Element Segment with ID xxxxxxxx was not found (probably deleted). Wait till after the changes are included in a tile build, and then enter the closure again and it should save fine.
Closing multiple segments
Real-Time Closures can be added to multiple segments simultaneously by selecting all the affected segments first. Be careful to verify all the segments after you save that the Real-Time Closures were added properly. It's been reported before when multiple Real-Time Closures were added at once, that some of the segments either weren't closed, or had incorrect details in the closure (e.g. direction).
Segment direction for one-way closures
If only some of the segments are one-way, or some one-way segments are in opposing direction (B-A, A-B), you can set the Closure as two-way for all the segments. When you save you will see an error line for each direction of a closed segment which failed to save because the segment is one-way. You can ignore the error, and all your segments should be closed in all possible directions. (Be sure to double check them all.)
Editing closed segments
NOTE: If a segment is closed using this feature, the segment will not be editable by any editors - regardless of rank - while the closure is in effect. This is by design, to prevent any changes to segment and junction node IDs which will corrupt the closure.
If you need to edit the segment, you will have to first remove the Temporary Closure (copy the details first), then modify the segment and save. Depending on the type of edit you can either replace now, otherwise you will need to wait for a tile update before being able to add a new Temporary Closure. Add a new Temporary Closure with the details you copied to the appropriate segments.
Understanding closures with an end date circa 1970
You may occasionally see an RTC in WME with an end date set as 1970-01-01 00:00 ±1 day.
- These may not be actively affecting routing in Livemap or the Waze app.
- They may be submitted by any rank user, even if the user is below the rank to have RTC permission.
- There may be more than one of this type of closure overlapping for the same segment and direction.
These are Closures reported from within the Waze app'.
A Closure reported from the Waze app does not include an end date in it. These closures are therefore reported to WME with no assigned end date. The end date field is essentially blank - it is "null".
In the Unix operating systems a time is encoded as the number of seconds passed since January 1st, 1970. A "null" date will be zero seconds passed and show a date time of 1970-01-01T00:00 UTC. Adjusted for time zones, and you could have a date-time anywhere from 1969-12-31T12:00, to 1970-01-01T12:00.
This explains the anomalies listed above;
- Because they are from the app, they don't immediately affect routing until there are multiple identical reports.
- They can be reported by any rank user.
- There needs to be multiple reports to activate them.
- It is possible to have than one report on the same segment.
These closures are editable by editors in WME who have permission to use the RTC feature. If you do edit and/or delete one of these app-reported RTCs the effects are seen immediately. If you change the end date, the RTC will start affecting traffic like any regular RTC immediately.
If there are multiple app-reported RTCs on a segment you may have to remove the duplicates before being able to save any changes to one of them, otherwise you may get an error for trying to create an overlapping closure.
There are generally two types of Closure Sheets;
- Regional Closure Sheets supplied by Waze staff and shared with the community leadership of some countries.
- Supported Major Traffic Events are also processed using a unique closure sheet for each MTE.
These Closure Sheets have some unique advantages over submitting closures directly in WME, and also have some unique guidelines listed here below. They still also follow all the general guidance for Real-Time Closures listed above.
Closure sheets vs closure feature in the WME
Real-Time Closures which could just as easily be submitted using the Closure feature in the WME, shouldn't be submitted using the Regional Closure Sheets. If there is some feature of submitting them through the Regional Closure Sheet easier somehow, then it is fine to use the Regional Closure Sheets for them. The Regional Closure Sheets may also have some features not yet available in WME, closures utilizing those features should be submitted through the sheets.
How to submit a closure using a sheet
Many aspects of submitting a Real-Time Closure in a sheet are the same as other forms of submission. However because the sheets are not part of the Waze ecosystem, there are some important differences. Not all Closure Sheets are identical, but they all follow the same general principals:
Username - You must enter your exact Waze Username as it appears in WME and the Forum. This allows Waze staff and the community leadership to contact you for any updates as necessary.
Permalink - You have to provide a permalink which shows all the segments you wish to close selected. See the Permalink article for details on how to create a Permalink which has the segments selected.
There may be other elements you are asked to provide to make use of some advance features of the Closure Sheets. There will usually be some instructions and guidelines included somewhere in the sheet.
The Closure Sheets are processed by scripts and contain formulas which automatically perform functions and calculations on the data you submit. To make sure you don't break the sheets, please be careful never to type or paste anything columns of sheet labeled "DO NOT EDIT" in the header row.
Closures not displayed on the map
Real-Time Closures entered using this feature are not subject to waiting for a tile update, they will go live as soon as they are uploaded by Waze. However, if you enter a Real-Time Closure for a segment which has been modified enough (e.g. changed the segment ID, node ID, or junction location) since the last tile update, the Real-Time Closure will not work until the new segment changes go live.
When entered through a Regional Closure Google Sheet the alert bubbles will likely show in the new location of the nodes, but the candy stripe and routing effects won't be implemented until the segment changes are live after the next tile update.
