TN Speed Limit Mapraid 2016 ended on 03 Oct 2016 21:00:00 UTC. Please check back here for results and check the Mapraid Forum for mapraid announcements.

The Tennessee Speed Limit Mapraid will be 23 September through 3 October 2016. The participants will be divided into several groups, one for each section of the map. Each group will have both local and senior editors, one of which will be the "Group leader" - listed in blue below. Please direct all questions to your group leaders. The raid hosts will be available across all areas for added support.


  1. The primary goal of this mapraid is to set speed limits on  Minor Highway  and  Primary Street  segments throughout the state of Tennessee. Freeways and Major Highways should already have 100% of speed limits set, but if you come across one that is incorrect please bring it to your group leader's attention.
  2. Roads with the  Street  type are also within the scope of the raid, but are considered low priority and editors should not expend significant time on them unless associated with an update request. Mass editing of speed limits on streets within urban areas based on local laws and regulations is discouraged during the raid.
  3. Many minor Highways are state routes that need to have their names properly formatted (see below for details). Doing so is encouraged if this can be easily done when setting speed limits.
  4. In light of the fact that many rural areas in Tennessee have significant amounts of basemap, please also make basic common-sense edits as you work on the mapraid goals -- fix bad turns and other obviously wrong information on the segments you are editing, but keep focused on the mapraid goals. If you see bigger problems that can be addressed later, or if fixing these issues would significantly impede progress on the other three goals, contact your group leader orGoogle form icon.PNGrecord it in this form.

When you are editing in the raid area, please set yourself visible and enable the Live Users layer. We will use Slack Channels If you are not already part of the WazeUSA slack team, please look for your invitation to slack after mapraid registrations are processed. If you have trouble getting into the slack team or your group channel, please reach out to one of the MapRaid organizers.

You can also use WME chat. The WME Chat addon is recommended.


Important / Mapraid guidelines

Choose imperial units.png

Please read the entire MapRaid wiki and familiarize yourself with the guidance on the Tennessee wiki page. If you are still uncertain what to do about something you see on the map, please ask your group leader Thank You for your help with the map.

Speed Limit Guidelines

Use Waze Street View to find Speed Limit Signs. You may also get information from local drivers. You may use information from local ordinances posted on county or city websites. Do not rely on predicted speeds (with "verified" check box).

Please set your WME preferences to imperial and enter speed limits in miles per hour.


Some segments have unverified speed limits. These speed limits were predicted by Waze. We must check each unverified speed limit. If it is correct, we can use the "Verified" check box. If it is not correct, we must replace the speed limit value.

Tennessee follows the US guideline for speed limits, with a few exceptions listed below.

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.
  • Where the speed limit changes, make it change in the map. A new junction may need to be added, but do not add a new junction for a speed limit if it will be within 200 feet of an existing junction.

Tennessee Specific Guidelines

According to Tennessee Code Annotated 55-8-152, the following maximum speed limits apply in Tennessee, with individual counties and municipalities setting lower speeds on individual roads as needed:

  • Interstates and limited access freeways (urban and rural): 70 MPH
  • Divided highways: 65 MPH
  • Undivided and two-lane roads: 55 MPH
  • Residential streets: 30 MPH

Do NOT use the above to set speed limits on roads! However, if a UR reports a speed limit higher than one of those listed above, the report should be treated with skepticism.

In addition, many counties and municipalities have enacted ordinances that establish default speeds for certain road classes. Use these data only as a last resort if you have exhausted all other options, and are able to confirm the absence of signage in street view. Even so, do not use this information to mass edit speed limits onto neighborhood streets, but instead focus on Primary Streets and above.

DO NOT map the following speed limits:

  • Construction zones - contact a state or area manager instead
  • Variable speed limits based on digital signs - these can be found on several freeways
  • School zones or other time-based speed limits - map to the maximum speed

Base Map Areas

There are still many areas in Tennessee which have not been touched by editors since the "base map" was imported in 2009. Only touch these areas if it is necessary to reach the objectives of this mapraid. If no information is available for setting Speed Limits, do not fix these parts of the map. These areas will be addressed at a later time.

  • Before setting speed limits on a segment, set the road direction correctly and correct all turns and other obviously incorrect information.
    • Please use the TDOT FC Maps (see link on the TN wiki page) to determine road numbers and format (SR-xxx or TN-xxx).
    • The FC maps list a large number of roads that had classifications upgraded in summer 2016. These roads are currently mapped as streets in Waze, but will be upgraded to Primary Street. Please do not fix these roads unless ALL other mapraid goals have been met in your area, as these will be addressed after the raid.
  • If roads are very bad and very difficult to fix, you may report the problem to your group leader.

Edit Quality and Mass Editing

You are responsible for every edit you make, whether you make it by hand or use a script. Every edit you make should meet the goals of this mapraid AND make a noticeable improvement to the map. Do not make edits simply to gain points without improving the map. If a segment is "good enough" for the waze map, do not edit it.

If it looks like you are making unnecessary edits or hunting for points, you may be banned from this mapraid and from future mapraids. In addition, Waze will throttle your edits and points if you use scripts excessively.

Again, DO NOT mass edit speed limits onto neighborhood streets in urban/suburban areas.

Update Requests (URs)

Some editors have made URs about speed limits they have seen on the road. These all contain the string "mph" or are tagged with [WSLM]. If you can find these URs, you can use them to help you set the correct speed limit on that segment.

Do not just update the speed limit on one segment where the UR was and close the UR. Do your research and update the speed limit on that whole section of road where the user has driven. Additionally, add any speed limits on any easily correctable segments such as connecting roads with visible speed limit signs. After all of that has been completed, please follow correct procedure with closing speed limit URs with appropriate closing comments. If you have concerns about one that needs to be closed, please let your group leader know.

Other types of URs are not a focus of this mapraid. If you spot a big problem which should be addressed, please let a group leader know.

Road Types, Names, and Functional Classification (FC)

Road type classification is not a focus of this map raid. Freeways, Major Highways, and minor highways should already be classified correctly, while Primary Streets will be addressed after the raid. If you see and easily-fixable problem on the segments you are editing for speed limits, please consult with your group leader before fixing it.

Road Names are not a primary focus of this map raid, but if you see an easily-fixable problem on the segments you are already editing, please fix it. State highway names need to be in either TN-xxx or SR-xxx format as per the TDOT FC maps. If you see any large problems with road naming, please let a group leader know.


Places are not a focus of this mapraid. If you see obviously incorrect places that will cause incorrect routing or a staff locked advertisement place that is wrong, please let your group leader know.

Issues to Address after the MapRaid

Any major issues that need to be address will be followed up by local editors after the MapRaid conclusion. Issues such as city name merging, large scale naming (primary or alt), etc, will be handled after the fact. Remember, the concentration is speed limits and lock levels.

Mapping Resources

Use Street View and Satellite View from within Waze and the sources listed below. Do not use any unauthorized online mapping resources and if you have any questions on legitimacy of a resource, please talk to you group leader.

Warning: If you copy information from unauthorized sources, you may be removed from this mapraid. Also, every segment or place you edited might be removed from the map. Copying information from copyrighted sources is illegal!

Mapraid edit lists

Spreadsheets and forms are being used to streamline management of various group efforts and track important edits. Below you can find links to use these these forms, sheets, and see the lists.


Check back here after the raid is completed to see the results and achievements

MapRaid Promotions

Some editors really let their bright side out, and let their community skills shine. This is even more evident in a concerted group effort with high-density editing like a MapRaid!. Editors of all ranks working closely with each other and the Champs, really lets us everyone get to know each other, and allows certain editors to be recognized for their skills and effort.

When the Champs see someone consistently editing well, interacting well with the community, and knowledgeable of the various details from the Wiki, they can issue promotions. This can be anything from the size of a managed area, to a rank increase, or even a new role.

Watch here for results of promotions during and after the raid.
