Before editing the maps in Delaware, be sure to fully review and understand the editing manual.
The Waze user community follows the Waze etiquette guidelines discussed in the Wiki. Be sure to familiarize yourself with these guiding principals while editing the maps and this Wiki, as well as when communicating with other Waze users.
Here are some examples of resources that we cannot use because of copyright restrictions. See Using external sources for a general discussion of the problem. You can contact the copyright holders, representing no-one but yourself, and asking them to create a copyright/license notice that would allow anyone to freely use the information without attribution. The Waze team is working to come up with an allowed list of online mapping resources.

New editors should consider checking into the formal mentoring program available at no charge.
New Delaware editors are welcome. We need you. Please review the New Editors Guide and contact other editors in chat before editing. Please feel free to reach out to other Delaware editors listed below for assistance if needed, either in chat or "PM" (private message) on the forums.
Cities and towns
One of the most common errors when editing the maps is when an editor creates a road and does not confirm the road by setting the city and road name (or stating it has none).
Some states and territories manage a separate page on cities and towns to identify the specific city names that should be entered, and no others. For states that do not have a separate page to track the names, see this Wikipedia link and find the state or territory in question.
- Delaware uses SR-## for all state routes (e.g. SR-58)
- If the primary name is a street name and the road also has a US or state route (SR), add it to the alt name (e.g. Primary Name: Capitol Trl, Alternate Name1: SR-2, Alternate Name2: Kirkwood Hwy). If a divided road, also add the cardinal direction to the alt name. e.g. "SR-7 N" on the northbound side and "SR-7 S" on the southbound side. When using alt names, be sure to be consistent and avoid gaps in naming, as this can cause routing issues with detour prevention. If the road switches back and forth between divided and two-way you should add a simple SR-## Alt Name for the entire length as well to avoid detour prevention.
- Generally, regarding state route numbers, even numbers run east-west and odd numbers run north-south
- Some Delaware routes are continuations from other neighboring state routes. e.g., SR-273, SR-896, SR-299.
In Delaware we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.
|Highest rank of connected segments|
Note: Do Not Mass Edit just to update locks to these standards, these can adjusted as you find while editing other aspects of the segments such as FC, speed limits, naming, etc.
Some segments still warrant higher locks and care should be taken when setting segment lock to these standards to look for and protect these special setups with higher locks. Some examples; segments which are part of BDP, U-turn prevention, or using micro-doglegs, or other complex intersection setups.
Delaware follows the national guideline for speed limits, with a few exceptions listed below.
- When a speed limit changes at an intersection, the sign for the new speed zone can be found up to 200 feet after the intersection. Map the change at the junction if signs immediately after the junction on each side are different speed limits.
- If the speed limit changes more than 200 feet from the intersection, add a junction at the sign and make the speed limit change there.
- If opposing speed limit signs are opposite each other, attempt to make the change as close as possible to the actual speed limit signs but do not create a new segment if within 200 feet of a junction. When adding changing speed limits, choose the junction that is on the higher speed limit side. Basically if the change is going to happen slightly early or late, best to have a lower speed limit come earlier and a higher speed limit come later.
- Long term work zone speed limits may be mapped instead of the "ordinary time" speed limits. If placing a work zone limit, use Livemap to place a UR there, note that it is a temporary speed limit, and add [CONSTRUCTION] somewhere in the comment.
- If no speed limit sign is posted, the default speed limits in Delaware are
- Residential or business district: 25 MPH
- Two lane road: 50 MPH
- Divided highway: 55 MPH
Town Speed Limits
Do not assume every housing development is 25 MPH. Some localities have lower limits. Below is a list of some of them:
- Bethany Beach: 20 MPH
- Elsmere: 20 MPH
Delaware (especially NCCo) is really bad about signing speed limits on many roads. So even though the law says an unsigned road is above values, outside or rural areas of the state, that is probably not the case. May need to infer some speed limits based on signage pretty far down the highway.
Summary of National Guidelines
- Only map speeds found on regulatory white rectangular signs with black lettering.
- Do not map advisory speed limits (generally an orange or amber rectangular sign with black lettering).
- Where there are variable speed limits, map only the speed limit which is in effect most of the time during daylight hours (most hours of the day, days of the week).
- Do not map special speed limits for special vehicles. Waze only supports speed limits for private passenger cars.

Delaware uses a real elevation method to set road elevations. This method sometimes requires the use of extra segments. This has the benefit of an enhanced look in the Live Map, and, more importantly, makes it easier to close a bridge or tunnel without affecting traffic to nearby homes and businesses.
Delaware follows the standard USA guidelines for all of the following special road types.
- Divided highways and roadways
- Carpool, HOV, Transit lanes
- Roundabouts and traffic circles
- Toll roads
- Partial and scheduled restrictions
- Private installations and military bases
Review the Wiki guidelines for non-drivable roads to ensure compliance with the general guidelines.
- Divided Highways
- Carpool, HOV, Transit lanes
- Roundabouts/Traffic Circles
- Parking Lot Roads
- Toll Roads
- Alleys should always be mapped if they have a name.
- Alleys should always be mapped if they are the sole access to a home or business.
- Alleys should always be set to "Private"
- Alleys are normally mapped if they are acknowledged by the municipality.
If an alley does not meet the above criteria, mapping is optional. Leave the name field blank.
Generally, if a path can't be driven on (e.g. Walking Trail, Pedestrian Boardwalk, Stairway, Railroad, Runway/Taxiway) then it not normally mapped. If it is mapped, it should not be connected to any roads. This is due to the way the routing engine works, as Waze will route users to drive on these "Non-Drivable" road types.
It is permitted to map Railroads since some users run Waze while on the train and contributing false data to the system. This false data has been known to effect drivers on adjacent roads. Railroads should be level -5 and locked at the highest level of the editor.
Time Restricted Turns
There is beta testing for setting Time Based Restricted turns in WME. Watch for announcements in the forum on this feature
The Federal Highway Administration keeps a website indexing all states that can provide highway and construction project information. Go to the page, find your state, and check the links for the desired information.
Places considered fundamental to the functioning of the Waze app, such as Gas Stations, should be locked to Rank 3.
Complex, intricate, or crucial Places such as Hospitals, Police Stations, Fire Departments, Airports, Parks, etc. should be locked at least to Rank 4.
- This is to prevent loss of data due to automatic acceptance of Place Update submissions from Trusted Users, or Place Update Request approvals from other editors without careful examination.
- If you do not have a high enough enough rank to lock the place a Rank 3+, please lock it as high as you can, and consider asking a higher rank AM, SM, CM, or Champ to lock it higher.
Not every camera-looking device at an intersection is a speed or red light camera. Generally speaking:
Be sure to know your cameras before accepting new camera reports.
When adding a camera, be sure to review the camera placement recommendations.
Laws regarding speed and red light cameras vary between the states and territories, so be sure to understand the details of camera legality in Delaware.
Only Red Light Cameras are legal in the State of Delaware. More information can be found on the IIHS website for DE and other states.
Red Light Cameras
There is an ongoing discussion regarding all the red light cameras in DE in the Waze forums. Please post any needed updates/changed to red light cameras there, so local AMs and other editors can make appropriate changes.
- City of Wilmington
- All the rest of Delaware Except for a couple places they accidentally left off, which are listed at the Deldot traffic map, which includes one at Naamans and 202.
NOTE: It is important to check the DIRECTIONALITY of ALL red light cameras. In many (most) cases, the red light camera is only monitoring one direction of traffic. An example of intersection where this is the case can be found at US-40 and SR-896.
Other Camera Types
These are cameras or signs that either provide driver feedback or are used for traffic control. These devices CAN NOT issue tickets and should not be mapped.
To do list
Many states and territories keep an active list of pending or closed actions that need to be done in the state by the editors. All editors are welcome to contribute to the list of activities.
