Before editing the maps in Michigan, 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.

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).
Please list cities smaller than 100,000 under their county.
County Highways versus County Roads
- Michigan has an "intercounty" highway system in addition to locally maintained county roads. In both cases, naming conventions should follow highway naming by state.
- Numbered county highways are prefixed with A through H based on geography. Naming convention should be "CR-[Letter Prefix][#]" (i.e. "CR-D19"). In all cases, local signage should be used to designate a primary name, while the county highway designation could be an alternate name if appropriate. While these roads could conceivably be classified higher, the lowest road type used should be Minor Highway regardless of appearance or functional classification.
- A small number of counties maintain numbered county roads that are not part of the statewide A-H highway system. These roads should be named CR-[#] (i.e. "CR-388") and would typically appear as Primary Street, Street, or even Dirt Road.
State Highway Naming
The following proposal for a new national state highway naming standard is currently under review by the GLR State Managers.
- The city field for all names (primary and alternates) of limited access USA state highways (ex: M-59) should be empty and the "none" checkbox marked. This guideline only applies to those sections of state highways that are limited access and cannot have house numbers, thus making city names irrelevant.
Michigan 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
- Dirt roads
- 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.
(DRAFT) Median U-Turn Intersection (MUTI)
- NOTE: Although these guidelines have not officially been adopted as a Waze standard, the discussion is occurring at this forum thread. This section is in place as a guide for editors experimenting with this type of intersection while a consensus is being reached statewide or country-wide.
A Median U-Turn Intersection (MUTI) is a procedure involving an indirect left turn onto or from a split roadway onto another road where the direct left turn is prohibited at the intersection itself. A MUTI can only occur at the intersection with a cross street. Other median u-turns may be available at crossovers along a split road, however these would not be classified as MUTI since they simply facilitate going the opposite direction along the same split road. A reference figure showing both types of u-turns together appears below.
To execute the turn, the driver proceeds through the intersection to turn left at the next median u-turn, then turns left onto the same road (in the opposite direction), and finally turns right at the main intersection. Alternatively, if the intersection involves turning onto a split cross road, the driver could also turn right onto the intersecting split road, then turn left at the median u-turn, finally turning left onto the road and proceeding through the main intersection.
This procedure has proliferated in Michigan since the late 1960's, and is locally referred to as a “Michigan Left Turn (MLT)” or just “Michigan Left“, even in locations other than Michigan. The MUTI and its variants are now used or being considered in several states and other countries.
Other terms for this procedure in transportation literature from the Federal Highway Administration and individual states include:
- “Arizona Parkway”
- “Boulevard Turnaround”
- “Median U-Turn Crossover”
- “Median U-Turn Intersection Treatment (MUTIT)”
- “ThrU-Turn Intersection (TTI)”
In addition, there are a number of related procedures directed toward the same or a similar result as the MUTI. Consequently, some of these procedures may need treatment similar to the MUTI in Waze:
- "Continuous Flow Intersection (CFI)"
- “Reduced Conflict Intersection (RCI)”
- “Restricted Crossing U-Turn Intersection (RCUT)”
- “Super-Street Median Crossover”
In order to be considered a MUTI (or variant), proper signage should be in place. Depending on what entity maintains the road, however, the quality of signage will vary.
- Naming Convention: to [street name] [opposing direction] / to [cross street name] [direction]
- Similar to highway way-finder segments, the “street name” is instructional rather than official
- Example intersection of Mound Rd and Metro Parkway in Macomb County
- Driving north on Mound Rd: "to Mound Rd S / to Metro Pkwy W"
- Driving south on Mound Rd: "to Mound Rd N / to Metro Pkwy E"
- Driving west on Metro Pkwy: "to Metro Pkwy E / to Mound Rd S"
- Driving east on Metro Pkwy: "to Metro Pkwy W / to Mound Rd N"
- Road Type: RAMP
- Although this departs from traditional rules for At-grade connectors and for use of the ramp road type, it hides the instructional street name in the client. It is close to the exception stated on the at-grade connector page, however, in that a MUTI is a signed--though unnumbered--exit from the current direction of travel on a roadway.
- Junction Angles: Between 45 and 90 degrees
- The angles for the median u-turn should generate two "turn left" instructions. The first “turn left” should occur prior to entering and the second should occur while exiting the median crossover.
- Junction Position:
- The initial junction ideally should be as close to the start of the solid white line as possible (if present). This prevents a turn instruction from occurring too early or too late. In many cases, this will require adding a geometry node at the start of the segment at the most detailed zoom level to generate the correct turn angle.
Sample MUTI as it appears in Waze Map Editor:
Distinction between MUTI and standard crossovers:
As a general rule in Michigan, only residential alleys should be mapped, and only if they are the locally accepted destination for parking at or near a residence. Alleys should only function as a starting point or final destination, not as a thoroughfare. If alleys are mapped, the road type should be set to "Parking Lot Road" and given the name "Alley". Other attributes (city, direction, turn restrictions) should be set as if the alley were any other drivable road.
When adding or editing an alley, an important consideration is to verify that house numbers are properly situated for the surrounding street segments. Waze will route to the closest segment for a set of destination coordinates. This may result in the destination being in the alley, which may or may not be the desired result. Refer to the FAQ for additional information. If you need guidance or are uncertain whether a certain alley would meet the criteria to be mapped, please post a permalink in this existing Michigan forum thread.

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.
Currently only the Waze client app can add cameras to the map. When adding a camera from the app, 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 Michigan.
While traffic monitoring devices are employed in the state, no cameras are used for enforcement or issuing citations according to the Michigan State Police.
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.
- Functional Classification Inventory
- Freeway Consistency
- State and County Highway Consistency
- Ferry list (add docks as Point Places)

Road Lock Standards
In Michigan 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.
