%X Most link speed estimation models based GPS data are only suitable for ideal condition in which the sampling interval is close and the sample amount is sufficient,but they are unable to estimate the real time link speed if GPS data are not enough.According to the space distribution of GPS data,combined three models,which could maximize the utilization of GPS data and the road network coverage of speed estimating results.It taken uneven distribution of GPS data into account and adopted back propagation neura...
