  1. ※1 The data does not include information that can be used to identify a specific vehicle. So a vehicle may appear on multiple trips but cannot be specified.
  2. ※2 Vehicle location (described by latitude and longitude) is calculated using the position of the rear center of the vehicle.
  3. ※3 Kiloposts are distance markers that are placed along the Hanshin Expressway Route 11 Ikeda Line (Osaka bound).
  4. ※4 Vehicle size classification is divided into two: standard and large (over 6 m in length), and it does not include motorcycles.
  5. ※5 Road surface information is the road information for a certain car at a certain time and location.
