Wisconsin/Major roads/Main

Functional Classification

Wisconsin follows the Functional Classification (FC) system for the USA.

To help update the current Wisconsin roadways to the new functional classifications, go to the Wisconsin Functional Classification Inventory.
Links to the FC maps for the state of Wisconsin can be found on the Wisconsin/Resources page.

Name Normalization

Wisconsin uses the following standards for road naming:
Freeways - I-###
US Highways - US-###
State Highways - WIS-###
County Highways - CH-XXX
Forest Roads - FR-###

There are no Township (Town) Roads in the state. All Town Roads are named, and those names will be used. The only exceptions would be if the road signage states differently.

Bridge and Overpass Segmentation Elevation (BOSE)

Please note that there are regional and national discussions ongoing for establishing standards beyond state level. If those changes come in opposition to what we are doing here, then we will be changing to follow suit.

Wisconsin has decided on a state standard for the segmentation of bridges and overpasses.

The National Wiki contains the standard information regarding proper elevation of segments. What we are doing in Wisconsin is expanding on those standards to create a more accurate representation of the segments.

Basic elevation is determined using the following rules:

• All roads start at Ground elevation
• If a segment is above another segment, it should be set to +1 relative to the lower segment's elevation (to account for multiple segments overlapping)
• If a segment is a tunnel (not just an underpass), it should be set at -1, and Tunnel should be checked.
  

Bridges
Definition:

• If a segment travels over a river or body of water, it is considered a bridge
• If a segment travels over another segment, it is considered it a bridge (aka: overpass).
• If a segment is artificially elevated to pass over ground level objects and natural features, it is considered a bridge.
  

Junctioning:
Place a junction at the start/end of the bridge where the land falls away.

• If there is already a junction within 500 feet of the bridge, do not add a new junction.
• Do not create segments less than 200 feet in length.
  

Ramps
Ramps should always be set to Ground. The only time a ramp segment is set above or below ground is when it travels above or below another segment as a bridge or a tunnel. This is most often the case in large interchanges, like the Marquette interchange in Milwaukee. When a ramp traverses over or under another segment, you should follow the elevation guidelines listed above.

Do not segment (cut) a ramp like you would for a bridge, unless it takes on several different elevations.

Because of the complexity of interchanges, please contact your State Manager before making adjustments.

Special Note

This process was derived from the Seagull Effect created by the Australians. The process has been unofficially called ‘seagulling’. Please note that this word is a misuse of the Seagull Effect. Using it may have unintended connotations.

Additional Notes For Wisconsin

New Roads

It is important to remember to add House Numbers (HNs) when adding new roads to Waze. Waze will not be doing any future imports or merges of external data for house numbers. This ensures that Waze will provide accurate routing to those new addresses. If you come across a new road that is part of a new residential development but HNs are not yet available, please add the road to the Wisconsin New Development Tracking Sheet. Add any relevant information to the project that you may have. This sheet is used to keep track of new developments to ensure roads and HNs get added to the map as quick as possible.

Dirt Roads

Example of a 2-track road. This would be set as Off Road / Not Maintained

All drivable unpaved (Dirt/Gravel) roads should be classified as per Functional Classification. The Unpaved checkbox should then be selected. Use the unpaved road attribute when the road is dirt or gravel but is maintained or improved by the city or county. This means that road is graded and leveled from time to time.

Trails and non-standard roads that may require special equipment to drive on, should either not be mapped, or be classified as an Off Road / Not Maintained. The Off-Road/Not Maintained road type will be used for 2-track jeep trail type unimproved roads. The Off-Road/Not Maintained type of roads are normally found in the rural areas of the state and should rarely be used around or in any city environment.

Using unpaved on a Local Street road type adds a time penalty to those segments of road and using Off-Road adds a larger time penalty. The time penalty is used by the routing server to determine the fastest route. In the app, there is a setting for Dirt roads. This can be set to Allow, Don’t Allow, and Avoid long ones. Just small lengths of Off-Road/Not Maintained will add a significant time penalty and these roads will be avoided by the app and may give users very long routes where the unpaved road attribute would have saved hours of time.

If you can't decide on what type to use just think, if a typical highway vehicle could easily travel at 15-25 mph should be considered a Local Street with the Unpaved road attribute.

Toll Roads

There are currently no toll roads in Wisconsin. No segments within the State of Wisconsin should be marked as 'Toll Road'.

Pedestrian Boardwalk, Walking Trail, Stairway

These should not be mapped without approval from a State Manager for Wisconsin or the Regional Coordinator. These segment types can cause routing issues even when not connected to a drivable segment.

Solid White Lines

It is not illegal to cross a solid white line in the State of Wisconsin, unless posted Wisconsin Statute 346.13(3).

Some examples are: road edge lines, lane divider lines, or on/off ramp lane lines. Even though it is not illegal, it is a safe driving practice to not cross these lines. When mapping on/off ramps, please follow national guidelines in the Junction Style Guide/Interchange page.




There may be times when this is impractical, in such instances, contact a State Manager for further guidance.

Roundabouts at Freeway Interchanges

When there are roundabouts at freeway interchanges, leave the connecting overpass/underpass roads un-named. Waze will read forward to the next roundabout and provide proper TTS and visual prompts for the user to aid in proper lane selection at multi-lane roundabouts.
Here is an example of when not to name the segment(s): Do Not Name

U-Turns

U-turns in Wisconsin are permitted when:

1. The u-turn can be made in safety and without interfering with other traffic.
2. Not upon any curve, or upon the approach to or near the crest of a grade, where the vehicle cannot be seen by the driver of any other vehicle approaching from either direction within five hundred (500) feet.
3. Not explicitly prohibited by signage or local municipal law.
4. You are not required to back up during the course of the u-turn in order to complete it.

For Waze routing, u-turns should only be enabled where they provide the potential for improved routing, which includes recovering from missed turns. A common example is a median-divided primary street that has homes/businesses with their driveways/entrances directly on it, where reaching them would otherwise require lengthy, multi-turn deviations through side roads in order to end up on the correct side of the median.

U-Turns are not allowed on any Freeway or Expressway.

Construction Zones

If a construction zone is expected to last one week or longer, the following options are allowed to be made to the area:

• Change speed limit to lower posted limit
• Add crossovers for traffic changes and make one-way Freeway segments two-way.

If any or all of these changes are made, add the construction zone to the following spreadsheet for easy reference and followup by other editors. WI Construction Zones

Locking standard

The following defines a set of minimum locking standards proposed for all roads within Wisconsin. Any road of a certain type or category must be locked at least to the level in the chart below. Roads may be locked higher for protection and special situations (tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.

It is understood that more rural or inactive areas may not yet meet this standard: editors are encouraged to recruit and mentor additional editors to build coverage.

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.

Wisconsin Minimum Road Locking Standard
