動態交通資訊之技術開發與應用研究(二)─車輛偵測器研發之功能擴充

Abstract

目前車輛偵測系統已成為智慧型運輸系統重要的一環，傳統蒐集路況資訊之偵測器，多直接引進國外產品，不但價格昂貴，其後續的維護及相關技術都受限於國外，而且這些偵測系統並不完全適用於國內的路況特性。本研究團隊自94~96年持續對雷達微波偵測器的相關技術研究，目前已研發了國內第一顆車輛偵測器的CMOS晶片，並且結合了自行研發之雙陣列天線，完成國內第一個微波偵測器之雛型，經過初步測試後，其效果甚佳。因此，本計畫將延續96年度計畫成果，持續擴充及改善所研發之微波式車輛偵測器。本研究期望所研發之車輛偵測器，具有穩定於戶外長期運作之能力，且符合國內車流特性，並藉由專利之申請，達到扶植技術研究與落實產品開發的目標，以創造出適合本土型的車輛偵測技術，降低硬體設置的成本與提高系統的準確度。

Presently, the surveillance systems become important issues in ITS. In Taiwan, the vehicle detectors are imported till now. The detectors are expensive and unsuitable for the local circumstances. Also, the detectors have high maintenance costs and the foreign companies own the core techniques. The research team has studied the techniques of the vehicle detection systems from 2005 to 2007 and has many breakthrough achievements in this area. As for the microwave-based vehicle detector, the CMOS IC of vehicle detector (first developed in Taiwan) and the antennas developed by ourselves compose the embryo detection system, and the embryo has good performances. Hence, the research team will extend the previous works to promote and improve the capability of microwave-based vehicle detecting systems. We hope the study of microwave-based vehicle detecting systems as a beginning to integrate the industries of vehicle detectors, to manufacture systems with low cost and high accuracy, and to apply patents in the future.
