traits

specific traits, that characterize subsegments of this slow traffic segment with different severity (moderate traffic, heavy, ...). Please note that this property does not specify how many of the subsegments there are, it rather is a summary of different conditions within 1 single traffic congestion. This is so because different clients may choose to know about all types of traffic, but ignore not-severe congestions in their UI. This is also expressed in the fact that traits is a Set and not a List: it's not ordered by its nature.

For example, for a single slow traffic segment composed of moderate (=) and heavy (#) traffic:

Your path:

-----|=======##======######=====####====|--->
     |<--      SlowTrafficSegment    -->|

The traits property would be a Set containing 2 entries: {MODERATE, HEAVY}, summarizing 4 moderate and 3 heavy subsegments, without describing their number or order.
