{{mbox|type=important|text='''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.}}
Oftentimes roads on the map 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.
* [[File:Closure arrow in WME.png|right]][[File:Closure_report_button_in_client.png|right|60px]]'''{{#ifeq:{{SUBPAGENAME}}|Real time closures|[[#Real time closures|Real time closures]] (this page)|[[Real time closures]]}} —''' 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 prevents 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.''' <br />Real-Time Closures can be submitted in a variety of methods discussed in detail further on this page:
** Add a [[#Closure feature in the waze map editor|closure in WME]]
** Submit a [[#Major traffic events|Major Traffic Event]]
** Enter a closure using a [[#Closure sheets|regional closure sheet]]
** [[#Report closure feature in the waze app|Report a closure in the client]] as you drive by them.
* [[File:Restriction_arrow_yellow_mouseover.gif|right]]'''[[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 and names|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 situation.
* '''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|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|Report a Closure in the Waze client app]]
*[[#Major traffic events|Major Traffic Events (MTEs)]]
*[[#Temporary closures in wme|Temporary Closures in WME]]
*[[#Closure sheets|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 [[#Major traffic events|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 ===
==== Illustrated slideshow ====
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|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 ====
[[File:Livemap closure alert.png|250px|thumbnail|right]] Adding a Temporary Closure does not put your name as the last editor for the segment (<small>Updated By: user (#)</small>), 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 {{u|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 names/USA#Construction zones and closed roads|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 [http://wikipedia.org/wiki/ISO_8601 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 =====
{{mbox|image=[[File:Clock.png|40px]]|text=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.
===== Time zone =====
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 =====
{{red|'''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 2011-12-01 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 [http://support.google.com/waze/answer/6081233 Waze Help Center].
=== 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. Only if Waze decides not to support the event, or if you don't have at least one weeks advance notice should you submit these closures through other methods.
To notify Waze of a coming event in your area, use the [http://docs.google.com/a/google.com/forms/d/1R0XIsGkHQmk8Nc0U5DDID1PwMQWqLMwmindiLDFwcjo/viewform 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 [http://script.google.com/a/macros/google.com/s/AKfycbwegLpBUyCBB07OBDXHK8H5Js3ynsGkmn8YFI-NGxS_7--JDGud/exec Waze Mini Site] <small>''(if the mini site gives an error try refreshing the page)'' </small>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 [[#Closure sheets|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 ====
If your event is going to receive further support as an MTE, or if more information is needed, Waze will be in touch after the form is submitted. Waze further supports some events by providing local push notifications, inbox messages, social media announcements and/or website features on the [http://www.waze.com/events Major Events page] on Waze.com.
If Waze notifies you that your submitted Major Traffic Event will not be supported, or if you have less than one week advance notice of the closure, you should submit the closure through one of the other [[#Real time closures|Real-Time Closure methods]].
=== 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 varioius levels aceess to the feaure.  If you would like to request access, contact a member of the community in the [http://www.waze.com/forum/viewforum.php?f=663 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 [http://docs.google.com/forms/d/1oGINt4UEkBV0Par5VCingXzTZpJq9KjG8GbZpGqbRow/viewform  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 {{key press|Add Closure}} button in the left panel.
# Click to {{key press|+ 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. '''{{red|NOTE:}} End date can not be more than 183 days after the start date.''' (see [[#Start and end time settings|below]] for more information.)
[[File:Add closure details.png|center]]
==== 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 {{u|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 '''{{red|(!) 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. {{Red|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 =====
{{Red|'''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.
=== Closure sheets ===
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 Mega 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 closure|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.<br />
'''Permalink -''' You have to provide a permalink which shows all the segments you wish to close selected. See the [[Waze Map Editor#Permalink|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 {{u|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.
