Mapbox Traffic v1

Source ID:
mapbox.mapbox-traffic-v1

This is a guide to the layers and data inside the Mapbox Traffic vector tile source to help with styling.

Overview

Mapbox Traffic provides constantly updating congestion information on top of Mapbox Streets road geometries.

When you publicly use styles or software that use Mapbox Traffic vector tiles, you must display proper attribution.

Line offsets

Mapbox Traffic can be used 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.

Data updates

Mapbox Traffic receives two different types of data updates:

  • Traffic speeds and densities: used to derive congestion, updated approximately every 5 minutes
  • Road geometries: based on OpenStreetMap, periodically updated
