PURPOSE: An integrated loop type vehicle detecting device using a loop coil and a parking information system using the same are provided to facilitate installation and maintenance by integrating a small loop coil with a loop type vehicle detecting device. CONSTITUTION: A body part forms an outer shape. In a differential loop coil, two or more loop coils are formed inside the body in order to generate difference of a distance till a bottom structure of a vehicle to be detected. An inductance evaluating part(104) receives an electrical change induced by the vehicle from the loop coil, and increases sensitivity of a signal. A communication part(105) transmits a vehicle detection result from the inductance evaluating part. |
