Common errors: Improve your skills!
This Wiki page is not supposed to be a full manual of how to edit the Waze Map. It is an overview of subjects that are often confusing for starting editors, because they do not know the guidelines yet and their own logic tells them differently. This is not surprising because many of the guidelines have changed over the years and if you don't know the history, you don't always see the logic. All (starting) editors had this issue. And because guidelines are still changing and will keep changing, this will also happen to more experienced editors. In addition, the technical working of Waze changes often.
On this Wiki page, we have tried to combine technical knowledge of Waze with the users guidelines in India. It is a helpful tool for senior editors to refer to when explaining the concepts to starting editors. To keep duplicate texts to a minimum, we also refer to other Wiki pages [disclaimer].
The best advice we can give to starting editors is to just start. Pick a topic that is of interest to you and practice the guidelines. If anything is unclear, just ask your community.
Other editors are very willing to help. While reading the information in the Wiki or getting it from other editors, please keep in mind that, like in real life, also in Waze things are not always black and white. That is why we say we don't have rules or regulations, but guidelines. You may receive several opinions from two experienced editors and both can be correct, although a different interpretation. In addition, exceptions to guidelines are always possible and not a problem, provided you have good arguments.

Most mistakes are because of a misunderstanding of the overall principle: 'Waze is not a topographic map, but a navigation tool'. Many starting editors try to make the map in Waze an exact copy of the actual situation. Roads are split; pedestrian boarding walks and cycle paths are added; perfect rounded corners and area places are exactly drawn. The actual goal of Waze is to get the best routing instructions. The less detail on the map, the easier and faster a map can be interpreted during driving, especially on small smartphone screens.
Another reason to keep the detail as low as possible is speed. The less details the less bandwidth the downloading of the map requires. Also the less junctions there are, the faster the route calculation is. The number of junctions that Waze can handle in one route is limited. So keeping the number of junctions as low as possible allows for a longer route.
To help you Waze has created a number guidelines. That is what this page is about.
Editing errors are inevitable
Everybody, without the need of any prior knowledge or practice, can start editing the Waze map. Therefore, Waze accepts the risk that users make edits that seems logical to them, but lead to undesired results. The Waze community is enthousiastic and active, so the mistake will often quickly be noticed. A more experienced editor will contact you to correct the mistake or do the correction himself. It is not meant as criticism, but an encouragement to learn more about editing.
Mistakes are often the result of a misunderstood or unknown guideline, or a lack of technical knowledge. In fact, there is only one true "mistake" you can make, which is withholding from communication with other editors.
Make sure that other editors can contact you
The only true mistake you can make as an editor, is being unreachable to other editors. If editors spot your edits with an undesired result, or if they don't understand the reason why you made this edit, they will try to contact you. They want to increase the quality of the map and at the same time help you to become a better editor. If other editors cannot reach you, they cannot help you! Moreover, they will probably change your edits according to their own interpretation of the situation.
Therefore, make sure that you can receive e-mails from Waze by providing a valid mail address. Check your mailbox regularly. Also check whether e-mails from Waze are not delivered to your spam- or junkfolder. You might want to make a filter to move the e-mails from Waze to a specific folder, or even create a separate mailbox for Waze. If needed, adjust your Waze settings. See the extended info about communication tools.
You might also want to get in touch with your community and get to know the Area Managers in your neighbourhood (link) who have shown good editing skills and have been allocated a specific area to look after.
Basic principles of Waze
Because Waze is a navigation tool and not a topographic map, some things may be drawn differently than expected. Waze is developed for drivers of cars and should not be used for other means of transportation like pedestrians, pedal cyclists, public transport, or commercial transport. Also, Waze is not meant to include your personal favorite places, historic railways and illegal shortcuts. While editing, keep in mind the following 3 principles:
When it comes to the map, the first and foremost goal of editing is to provide the driver with a map that is easy to follow on a small display, and to produce sensible verbal instructions when (and only when) they are needed.
- It is not a goal to model the physical roadway lane-by-lane. Doing so often leads to unnecessary complexity--which means a cluttered map, confusing verbal directions, and lots and lots (and lots!) of extra map maintenance.
- Do NOT map every road you see. Waze is meant for car drivers. If a road is not accessible to cars, it often is not useful to draw this in Waze. Pedestrian area's are usually only drawn if they are useful for navigational purposes. When in doubt, contact a more experienced editor.
- As a result of people driving with Waze on, road segments retain certain information (e.g., average speed) that is used in route optimization. When a segment is deleted, that information is deleted too. Given a choice between deleting a tangle of segments and creating new ones, or untangling them and reusing them, it is often better to "recycle".
- Does the area look different on the satellite view than the roads show? Check if the roads have been recently updated before changing it - satellite imagery might not be up te date.
- Are you working in an area which has been edited recently? Remember that this has been done by other editors who have invested their time trying to make the roads and cities as accurate as possible, so please be careful before changing others' work. Rather contact the editor first and discuss the changes.
Common functional problems
Incorrect or incomplete data can have a negative effect on the navigation or even make it impossible to navigate to a specific location. We call these functional mistakes and they should be corrected as soon as possible. Functional mistakes are, if noticed by an other editor, often directly corrected because of the great impact to the functionality of the App.
When a road does not have a city- or street name, it will get a red outline in WME and it won't be used for navigation. These roads can originate from
- Paving roads, who have not been confirmed in the WME.
- an editor added a road, but forgot to give it a name.
Before you delete a segment, first consult the editor who added it. If you think the segment is an improvement to the map, fill in the missing data. Also check the junction arrows; when an editor has forgotten to fill in the name, probably the junction arrows are not set either.
Read more information in: Create a road.
>> Checked/updated up to here <<
Junction Arrows (JA)
Junction arrows used to be called Turn Restrictions. Junction Arrows are the red, green en orange arrows when you select a segment. They control which turns are allowed. Green is allowed, red is not allowed and orange is partially restricted. You can also restrict entrance based on vehicle type but this feature is not yet functional in the routing calculation.
When you change the driving direction of a segment always remember to check the junction arrows. The WME does not adjust them automatically based on the driving direction. The quickest way to correct hem is to select the junction and press q and w or click on the button 'Allow all turns'. When creating a new road by default all JA's are red. In the advanced settings of the editor check the option 'Draw new roads with all turns allowed'. If you select this option, it is advised to also check the option 'Draw new roads as two-way'.
An easy way to check incorrect red junction arrows is Shift-Z. This will show all the red arrows in the area on your screen, also for the not selected segments. Of course these are not all incorrect, but you can check them. It is advised to before you do the correction, you press Shift-Z again and select the segment with the red arrow. Otherwise you can not see which segment has the red arrow.
Even when segments appear to be connected on your screen, it does not necessarily mean they actually are properly connected. The fastest way to check this is to select one of the segments. When you don't see the Junction Arrow(s) light up, it is not connected.
When a road should be connected, please check the Junction Arrows. If it is not connected, move the end node away from where it should connect, and drop it somewhere else. Than pick it up again and drag it to where you want the junction to be. WME now automatically creates a junction. Again, check the [Arrows].
If you cannot connect a segment using the above described method, one of the segments could have a lock level higher than your editing level. In that case you cannot solve this functional mistake yourself and you might want to ask for an unlock. If the segment is a pedestrian boardwalk, check whether this segment should be connected anyway. If you are unable to connect the segment and cannot get a hold of a more senior editor that can make the connection, leave a gap between the 2 segments. That way it is clear to other editors that this segment still needs to be connected. If you place it onto the other segment it will look ok at first glance but routing instructions will not function properly.
To protect the map from unwanted errors, some segments are secured with a lock. Important main roads will show higher locks than small side streets. Locked roads can only be changed by editors with a rank the same or higher than the lock level. Even if you succeed to edit such a segment, you won't be able to save your changes. Also, you will not be able to connect other roads to locked roads. If you try to do that, it will result in disconnected segments, like described in the previous paragraph.
When you want to change a segment with a higher lock level than your own rank, propose your changes to a higher rank editor, or ask a temporary decrease in lock level. You always need to make a permalink, and specify the region or city, and the needed rank.
Use one of the following methods:
- Use the appropriate channel in one of the chat platforms.
- Use a private message (DM or PM, in forum, Slack, or Hangouts) to ask the last editor, who is visible at the bottom left of your screen when selecting the segment. If you do not get a response, you can also ask the Area manager or one of the Local Champs of your country instead.
Incorrect use of roundabouts
When approaching a roundabout specific instructions are given. For a standard roundabout (4 exits) the instruction is 'Turn left at the roundabout'. For other roundabouts the instruction will be 'Take the third exit at the roundabout'. If these instructions are not correct for the situation, please don't use a roundabout. A dead-end street should not have a roundabout at the end. If there is no road sign for a roundabout don't use a roundabout. This will give incorrect instructions, where a driver thinks he is approaching a roundabout, when this is not the case. for more information about how to create a roundabout see [User:Moweez/WME_Quick-Start#Create_a_roundabout Quick Start Guide].
Private access roads that distort routing
Many new editors enthusiastically start mapping all small streets, alleys, driveways, parking lot roads, etc. They think "if I can drive on it, I should map it". But this can have some negative effects. Of course it means a lot of extra data (bandwidth) and extra calculations. Also it can make the map less clear on small screens. But the biggest disadvantage is that it can distort the routing.
The way Waze works is that is it finds your destination based on GPS coordinates, in a lot of cases from Google. Based on those coordinates it pins your destination. Then it looks for the closest drivable road, without looking at the name of that road. So that means if the driveway of the rear neighbors is closer to the pin of your destination then you will be lead to the wrong road. And when this is a long road, it can be far of from your actual destination.
Local agreements (that are not logical at first glance)
Waze users have gathered to make agreements on how to best implement Waze's functions and features. In addition, every country has different laws, habits and regulations. Therefore, agreements within local communities of Waze also can vary. These agreements may not always seem logical at first. However, they exist to ensure the best navigation possible, with the features Waze offers, and the with the least amount of data used. If you have made edits that were not in accordance with these agreements, you might have been asked to update them. Here is where you can read why.
The relation between the satellite view and map
Starting editors often tend to draw the map exactly like the satellite view shows. However, the Waze map should be as simple as possible, in a way that yield the best navigation instructions, with a clear and simple map on screen. This implies that sometimes roads or parts of roads are even NOT drawn, or drawn differently from the satellite view. In addition, the satellite view may be outdated or doesn´t show everything. For example, a road in a forest is probably not visible on the satellite view. Thus, use the satellite view as a source, not as a goal to copy. In case the road is mapped differently, please consult the previous editor or the area manager.
Many examples can be found in Advanced editing Guide.
Too many geometry nodes
Too many geometry points can slow down the build of your screen. Also, it is harder to maintain the map. Therefore, we use as few nodes as possible, even if that means that a road in Waze does not exactly follow the road in the Satellite View. If a segment has too many nodes, please remove them by hovering your mouse over the nodes, and press 'd'.
For more information see Create a road.
Simplify an intersection
More examples of drawing complex situations can be found in Advanced guide.
Starting editors often tend to change the road type of a segment. E.g., we often receive questions why the rail road type is not used for a rail road in the BeNeLux. Obvious question, of course, but the answer (see below) is not that obvious. Choosing the type of a road segment has many implications, due to the consequences for visibility, routing and such. These typics can vary across countries and you will see some of these differences when choosing another language in WME. Thus, some road types are differently used than expected at first sight, and some are even not used. If you think a road type should be changed, please consult the last editor or the Area or Region Manager.
More information on the use of the various Road Types in the BeNeLux are different. Therefore check this page
Freeway / Highway
Freeway and Highway are both translated to the same word in Dutch ('Snelweg'). In Waze however, these road types are mainly applied based on the amount of traffic they bear compared to other roads in the neighbourhood, the distance they serve in routing, and the passage possibilities. Therefore, a small local road can be defined a minor highway, and a normal street in a city that serves ongoing traffic as a major highway. This way of dealing with Road types is called Functional Classification (FC). Most of the roads that serve ongoing traffic, will be locked. Changes to these segments can only be made by experienced editors with a rank similar or higher than the lock level. If you think a change to a locked segment is needed, ask an editor with the appropriate rank, or place your request on the map modification forum in Belgium, the Netherlands, or Luxembourg.
Pedestrian boardwalks and cycle paths
In general both Pedestrian boardwalks and cycle paths should not be added to the map of Waze, because Waze should only be used by motorvehicles. There are some exceptions and they are explained in Wiki non-drivable roads. One of the exceptions is when a non-drivable roads are addeding a value as a landmark. In that case the PB is set to driving direction unknown and not connected to any drivalble road. In the Benelux Walking trails are not used for walking path, but for public transport, like train rails.
Also parking lots should be drawn as simple as possible with the aim at good navigation instructions. There is not value added to draw every lane on a parking lot and with the inaccruarcy of GPS Waze probably does not know on which lane you are exactly, resulting in wrong instructions. Roads on parking lots have no name, excepts when the road has a housenumber of an official address that can not be linked to regular street.
See Parking Lot Roads for more information.
Splitting up roads
Splitting roads into two single segment for both lanes should only be done when it is needed for navigion. The fact that a road is physically splitted, is not a reasons. With Junction arrows you can make sure that physically impossible turns are restricted. Splitting (or unsplitting) an existing road should only be done after consulting with the area or region manager. Be aware that unsplitting a road takes about the same effort as splitting it.
Update request (UR)
While driving, a driver can report a problem by submitting an Update Request (UR). Often there is not enough time to fully describe the issue. Therefore, Waze developed the possibility to start a conversation in the UR. Whenever you respond to an UR, you should take this seriously. The user does not report if he or she doesn't encounter a problem! It is your task to solve the problem as best as you can, or find the help needed to solve it. By solving the user's problem, we can improve Waze to serve the needs of all Wazers. Never just close a UR, even if you think it is bogus. Some general guidelines (your country may use different guidelines; always follow the guidelines of the country you are editing in):
- Start with thanking the reporter for reporting the issue.
- If the report is clear and you can solve this issue directly, please do and explain to the reporter what you have done. The reporter receives a message of your comment, and will feel valued for his/her addition. In addition, other editors can learn from your solution and it can help solving other issues in the neighborhood. You can close the UR as solved.
- When the issue is not clear, ask the reporter politely for more information.
- If the reporter doesn´t respond to your question within 5 days, you may send a reminder message. It often happens the reporters do respond only after a reminder.
- When the reporter also does not respond to your reminder within 8 days, you can close the UR as "Not identified", with a comment in the conversation why you closed it.
Officially, nobody ´owns´ a UR. However, if another editor is already handling the problem, don't close or take over without consulting this editor. If the editor does not react withing two weeks after the initial response, you may close it as "Not identified".
Samples of comments can be found in the script WME URComments.
Elaborate information on URs can be read in the US Wiki page Update Requests. Be aware, that if guidelines differ from what is written above, the guidelines of the country you are editing in take precedence.
Starting editors: what they can do and what not
Everywhere you have driven using Waze you can edit. In the Benelux the maps are quite good, so there is not much to do for a starting editor. Altough at first you might think there is not much to do for you, please zoom in and you can almost always find something to improve. Even in areas with a lot of editors you will find missing parking lot roads or a part of a street is missing. Also sometimes streetnames are missing or misspelled. Most work you can do is to remove unnessary geonometry nodes, see #Too_much_or_incorrect_geometry_nodes. Read the Wiki and just start editing, that way you will learn to use the editor and earn points to get to a higher level.
Because the maps in the Benelux are already quite good, there is also a risk with editing. You can break things that are working fine. Please be aware that some things might look incorrect or not logical to you, but can be correct based on the #The_principles_of_Waze. Be carefull with changing and deleting work of other editors. In case of the slighest doubt, first contact the previous editor.
To make this more clear we have made two lists, one of things you can do as a starting editor and one you should not do or be extremly caustious.
Risky activities for starting editors
Unless you work together with a more experienced editor be very careful with doing one of the following activities.
- Deleting road-segments. This also deletes the historic traffic information, e.g. the historic average speed.
- Do not change or delete segments that are connected to locked segments.
- Do not split roads, even when there lanes are physically split.
- Do not add non-drivable roads, like pedestrian boardwalks, cycle paths, railways, runways and bus lanes. This seems harmless, but they can result in a wrong navigation advice. It will also clutter the map and increase the amount of bandwidth used.
- Do not add parking lots roads when there are alreay roads on the parking lot. See Wiki PLR.
- Do change the roadtype, this has a big influence on the navigation.
- Be careful with adding roads, especially private roads and driveways. The same risks as for non-drivable roads apply.
- Do not close update requests or make changes based on them. If you want to help, because you have local knowledge, please make a comment that can help a more experienced editor.
Things a starting Waze-editor can do
- Read the Quick Start Guide.
- Check if streetnames are filled in and spelled correctly. Use sources, that we are allowed to use, to check.
- Check if the city names are correct.
- Check the driving direction of streets. You can base this on Streetview within Waze, your own local knowledge or other sources. When the source is older than the last edit on the segment, assume that Waze is more up-to-date than your other source and don't change it.
- Check if Junction Arrows are set correctly. With Shift-Z you will see all the red arrows. When you suspect a red junction arrow to be incorrect, first do Shift-Z again and select the segments connected to the junction one by onr. That way you can see which segment has the red junction arrow.
- Check the category, name and address of places. The name should be the official name of the place. If you know this place is called most of the times differently, please add that name as a alternative name. That way the search will improve. Also check if this place is visible on the live map, if not, please convert it to a point place, when applicable.
- Inform your area or region manager of possible issues. See the section #Communication how to do that.
- Monitor road-closures in your neighborhood, see this forum topic how to report them.
- Help with keeping the Wiki up-to-date and make it better. For example with suggestion to improved existing text or help with translations. See this forum how you can help.
