PROBLEM TO BE SOLVED: To accurately measure the electric field intensity distribution of an electric wave outputted from a road side wireless device.SOLUTION: An electric field intensity measuring device 10, upon detecting a signal 41 outputted from a vehicle detector 40, starts measuring the electric field intensity of the electric wave outputted from a road side wireless device 30. The electric field intensity measuring device 10 measures a distance moved from a position where a signal 41 outputted from the vehicle detector 40 is detected, and finishes the measurement of the electric field intensity when the measured distance reaches a pre-designated designation distance.SELECTED DRAWING: Figure 1

    【課題】路側無線装置から出力された電波の電界強度分布を正確に測定することを目的とする。【解決手段】電界強度測定装置10は、車両検知器40から出力された信号41を検知すると、路側無線装置30から出力された電波の電界強度の測定を開始する。電界強度測定装置10は、車両検知器40から出力された信号41を検知した位置から移動した距離を計測しておき、計測した距離が予め指定された指定距離に達すると、電界強度の測定を終了する。【選択図】図1
