環路線圈車輛偵測器之參數與佈設方式研討

Parameters and Layout Study for Looped Vehicle Detectors

本研究回顧環路線圈車輛偵測原理，探討目前於實務上的應用問題。藉由實際觀察與模式推估的方式，研擬在不同交通資料蒐集目的下，偵測器之佈設方式與於且各段中之位置、大小、形狀，並分析探討如何提升資料收集的準確率，以滿足交通控制的參數要求。研究重點涵蓋1.了解交通參數的偵測原理、2.探討交通參數演算合適的方式、3.線圈基本佈設型式及4.依車道別佈設位置之差異性研究。

This study firstly reviews the principle of vehicle detection via loop detectors, and its problems in practice. Based on the requirements of different purpose and sourced data precision, vehicle detector's layout particular about location, size and shape, to investigated through field survey and inference. The paper reported includes (1) the understandings of vehicle detection and loop detectors, (2) the reasonable algorithmfor parameter calculations, (3) the type ofloop layouts, and (4) the appropriate locations of the loop detectors embedded on the lanes.
