title: Traffic flow data XML tags meaning
body: <p>I am looking for real-time traffic flow data. I found the traffic API is what I need:
  Click <a href="http://developer.here.com/rest-apis/documentation/traffic/topics_v6.1/example-flow-bounding-box.html" rel="nofollow">here</a>
  but I really don't know what the meanings are for those XML tags, such as 
  <code>&lt;FI&gt;</code>
  <code>&lt;TMC PC="11531" DE="Linden" QD="-" LE="0.8535"/&gt;</code>
  <code>&lt;CF CN="0.86" FF="69.59" JF="0.17" SP="70.13" TY="TR"/&gt;</code>
  <code>&lt;/FI&gt;</code>
  I found the meaning of TMC DE PC
  But I cannot find CF CN FF JF SP TY. </p>
  
  <p>Anyone know these abbreviations ? </p>
  
  <p>Many thanks, </p>
