Sensitivity Measurement of Small Vehicle Inductive Loop Sensors
Keywords:
Inductive loop sensor, traffic sensorAbstract
The objectives of this research are to design and implement a more sensitive inductive-loop sensor used for traffic detector. The designed detector and the conventional detector are installed in a real traffic environment for sensitivity measurement. The results show that when a motorcycle pass over the detectors, the conventional loop and the designed loop has the maximum frequency deviation about 0.133% and 0.144% respectively. The results also show that the designed loop exhibits more uniform sensitivity over the loop area than that of the conventional loop.
