To reduce the size and increase the relevance of traffic data, the Traffic API allows you to limit the area and detail of traffic flow data and incident data that you can obtain via queries. In addition, the limitations listed below apply.
Traffic Flow Data Limitations
Although requests that specify very large spatial filters do not result in an error response, the response specifies a limited amount of data, as described above.
Traffic Incident and Zoom Level
- No display of traffic incident information: zoom levels 0-7
- Maximum bounding box width and height: 30 degrees of latitude and longitude
- Maximum permitted size of the proximity radius: 100km
- Maximum allowed corridor length: 500km
