A traffic flow feature, which extends the basic GeoJSON feature with properties extracted from
the traffic flow vector tiles.
Remarks
absoluteSpeed, partOfTwoWayRoad and openlr stay undefined, because the standard styles
do not request their tile tags.
No flow tile carries free-flow speed, travel time, delay or confidence. For historical speed and
congestion over an area, use the Traffic Area Analytics service.
