In addition to the standard wiki resources, considerations specific to Michigan include:
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.
Use of NFC Road Types
Examples of Michigan Roads by Type
- Detail for each road type and links to examples are available at Examples of Michigan Roads By Type
- Directory of county road commissions, many of which maintain a list of planned improvements or current projects
Speed / Red Light Cameras
While traffic monitoring devices are employed in the state, no cameras are used for enforcement or issuing citations according to the Michigan State Police.

National Functional Classification (NFC) Road Types
Rather than relying upon the appearance of the road, NFC considers the overall function of the road as determined by MDOT. While attributes such as number of lanes, speed limits, and number of access points are important aspects of the appearance of a road; they may have less impact on classification than functional considerations such as annual average daily traffic (AADT). Oversimplified, the essential idea from a functional standpoint is that numerous local roads feed into a smaller number of collectors, which then feed into a smaller number of minor arterials, which help funnel the majority of traffic into principal arterials and freeways for longer distance routing.
While there are exceptions that are listed below, the following table provides the NFC classifications with their corresponding Waze road types as adopted in Michigan. Although urban and rural boundaries appear on the NFC maps, Michigan editors currently make no distinction between urban and rural areas when coordinating road types between the NFC and Waze.
|NFC Type||Waze Road Type||Example or Comment|
|Other Freeway||Freeway||US-131 (Grand Rapids)|
|Other Principal Arterial||Major Highway||US-24 / Telegraph Rd (Detroit)|
|Minor Arterial||Minor Highway||North Territorial Rd (Ann Arbor)|
|Major Collector||Primary Street||Mount Olivet Rd (Kalamazoo)|
|Minor Collector||Primary Street||Typically rural only, often unpaved|
Prior to reclassifying any road segment to its NFC type, the following levels of precedence should be observed:
- Private roads should be classified as "Private Road" (even if dirt or otherwise unpaved).
- Public dirt or unpaved roads should be classified as "Dirt road / 4X4 Trail".
- Any road classified higher than the current NFC type due to a separate statewide standard or local editor judgment should remain as is. The rule as discussed in the Michigan forum is never to downgrade a road type, only upgrade to its NFC type. For example, a county highway with the Michigan A-H designation that may be a major collector in NFC would be classified as a "Minor Highway" due to other accepted guidelines.
- If none of the above conditions apply, the road segment can be edited to match the corresponding NFC type.
(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.
