Data description

nlc_data_5zones.mat

  • nlc_data: cell, contains 870 sequences of none-lane-change scenarios.
    • veh_s: subjcet vehicle
      • x: Lateral position (m)
      • y: Longitudinal position (m)
      • len: Vehicle length (m)
      • wid: Vehicle width (m)
      • v: Vehicle speed (m/s)
      • a: Vehicle acceleration (m/s^2)
    • veh_f: front vehicle in current lane
    • veh_r: rear vehicle in current lane
    • veh_ft: front vehicle in target lane
    • veh_rt: rear vehicle in target lane
    • veh_st: overlap vehicle in target lane
