This application discloses using multiple wireless vehicular sensor nodes to wirelessly receive multiple, time-synchronized vehicular waveform reports from the nodes to create a time synchronized system report, and preferably a time synchronized vehicular report. Each vehicular waveform report approximates a raw vehicular sensor waveform observed by a magnetic sensor at the node based upon the presence of a vehicle. The vehicular waveform reports, the time-synchronized system report, and the time synchronized vehicular report are products of this wirelessly receiving process. Also disclosed are apparatus supporting the above outlined process. Reception of the vehicular waveform reports may be time interleaved.
