Mapbox Traffic v1
This tileset reference document includes information to help you use the data in the Mapbox Traffic v1 tileset.
Overview
Mapbox Traffic v1 is a Mapbox-provided vector tileset that you can use to display real-time traffic conditions on a map. The tileset provides constantly updating congestion information on top of Mapbox Streets road geometries.
Line offsets
You can use Mapbox Traffic to display congestion for both directions on two way roads. When styling congestion, it's recommended that you add a positive line-offset to the layer to visually separate the directions of travel.
In regions that use left-hand traffic, road directions are reversed to allow for consistent line-offset styling of all roads.
Data sources
The Mapbox Traffic tileset is built from de-identified sensor data. Mapbox SDKs continuously collect de-identified data about the map and device location to update and improve our maps and services. To learn more about the telemetry data that goes into the Mapbox Traffic tileset, visit our telemetry page.
Data updates
Mapbox Traffic receives two different types of data updates:
- Traffic speeds and densities, used to derive congestion, are updated approximately every 8 minutes.
- Road geometries, based on OpenStreetMap, are periodically updated.
Attribution
You must display proper attribution in styles or software that use Mapbox Traffic vector tiles.

Classes
The main field used for styling traffic layers is class.
| Value | Description |
|---|---|
motorway | High-speed, grade-separated highways |
motorway_link | Interchanges / on & off ramps |
trunk | Important roads that are not motorways. |
trunk_link | Ramps and physically separated at-grade turning lanes connecting trunks to other roads. |
primary | A major highway linking large towns. |
primary_link | Ramps and physically separated at-grade turning lanes connecting primary roads to other roads. |
secondary | A highway linking large towns. |
tertiary | A road linking small settlements, or the local centers of a large town or city. |
link | Secondary and tertiary link roads |
street | Standard unclassified, residential, road, and living_street road types |
service | Access roads, alleys, agricultural tracks, and other services roads. Also includes parking lot aisles, public & private driveways. |
Structure
The structure field describes the grade of a road. Bridges and tunnels are not distinct from surface roads until zoom level 13.
| Value | Description |
|---|---|
bridge | Roads that lead over a bridge. |
tunnel | Roads that run underground. |
| no value | Surface roads and fords. |
Congestion
The congestion field is a measure of the relative slowdown a road segment is experiencing.
| Value |
|---|
low |
moderate |
heavy |
severe |
Road Closures
The closed field marks roads that are closed.
| Value | Description |
|---|---|
yes | Roads that are closed. |
| no value | Roads that are open. |
