      "roadType": "residential",
      "maxSpeed": 25,        // can be null - parsed from the OSM maxspeed tag, in mph; null if the road has no maxspeed tag
      "knownSpeed": 25,      //  maxSpeed if known, else the legal-default guess
      "isGuessed": false,    // true when knownSpeed came from the legal-default table
