Traffic data preprocessing system uses floating car on board Fourier transform to reduce communications requirements |
摘要 |
The traffic data preprocessing system measures (2) and stores (3) car speed which is windowed (4) transformed (5) to the frequency domain with Walsh or Fourier transform and the spectrum analyzed (6) and combined with mean speed to give a traffic status output value (7) which is transmitted to a central station.
