%X For the precision decline problem of existing vehicle detectors to ordinary roads, this paper presented a new method for the estimation up and down traffic flow with the acoustic signal of passing vehicles. The test results show that the wideband method is more feasible compared with narrowband method, and it is effective for the traffic flow detection.
