Websmoothing is utilized. To gain better insights of traffic conditions on the selected test-site, the high resolution floating car (GPS) data and the individual vehicle data from fixed-location roadway sensors are fused together to reconstruct the mesoscopic traffic state. Preliminary results obtained from Kalman smoothing are presented. WebDec 31, 2014 · DTIC ADA173914: Fixed Point Smoothing Algorithm to the Torpedo Tracking Problem. A sequential extended Kalman filter and optimal smoothing algorithm was developed to provide real time estimates of torpedo position and depth on the three dimensional underwater tracking range at the Naval Torpedo Station, Keyport, Washington.
