    C, when motor vehicles is when the upper distance travelled to distance tunnel entrance of Highway Pavement Structures (11) is L2, piezoelectric element group C(4) produced electric charge by motor vehicles load action and by this electric charge transmission to time difference (FBG) demodulator (8) and signal (FBG) demodulator B(9), time difference (FBG) demodulator (8) record piezoelectric element group C(4) the moment T2 of produced electric charge, time difference (FBG) demodulator (8) calculates piezoelectric element group B(3), piezoelectric element group C(4) time difference △ T, the △ T=T2-T1 of produced electric charge；Time difference (FBG) demodulator (8) calculates the traveling average speed V, V=(L1-L2 of motor vehicles simultaneously)/△ T；Signal (FBG) demodulator B(9) by piezoelectric element group C(4) produced by charge conversion be the signal of telecommunication, signal (FBG) demodulator B(9) by signal of telecommunication transmission to device controller B(10), device controller B(10) receive the signal of telecommunication after and trigger blower fan (12), illuminating lamp (13) is energized work simultaneously；
    D, on Highway Pavement Structures (11), roll the exit in tunnel away from when motor vehicles, time difference (FBG) demodulator (8) calculates tunnel ventilation illumination duration T, T=L3/V, T is reached when the working time of blower fan (12), illuminating lamp (13), time difference (FBG) demodulator (8) send closedown the signal of telecommunication and transmit to device controller B(10), device controller B(10) receive closedown the signal of telecommunication after and trigger blower fan (12), illuminating lamp (13) power-off simultaneously work.
