Improvement of Detection Method and Power Supply Device of Vehicle Detector

Abstract:

Automatic Vehicle Classification (AVC) detector, among traffic data collection devices, is very useful but operation failure or damage is often occurred due to unstable power supply, weather changes and poor road pavement condition, causing deteriorated data quality. In case of AVC detector currently used for detecting the vehicle type, 2 or more detectors are installed at the sections with similar traffic pattern, causing unnecessary cost. This study thus is intended to identify the problems with existing vehicle detector so as to develop the improved detector as well as evaluate the performance. This study is intended to identify the problems with existing vehicle detector and develop and evaluate the improved detector. The failure with AVC detector was mostly attributable to unstable power supply and environmental change and complex sensor and controller results in the high cost. Thus, to stabilize the power supply and reduce the failure by environmental change, improvement of the control part and enclosure was made and the cost was reduced by simplifying the sensor and control system and as a result of test, data accuracy, power stability and cost reduction could be achieve, proving high potential applicability to the site in the future.
