You can use the
flow resource to request traffic flow data containing speed and congestion ("jam factor") information for a geospatial area. The response data format is either XML or JSON.
The service supports the following geospatial filters (addressing schemes):
- bounding box (
- proximity (

RW) that fall within the geospatial address.
By default, a response contains all the available flow information for the specified spatial filter. It is, however, possible to add a further filter based on the functional class of the road through the parameter
maxfunctionalclass, and a filter for minimum and maximum jam factor values through the parameters
