摘要 路面之平坦度對於行車之舒適度有很大的影響。在汽機車日益成長之現況下，如何有效快速地收集路面資訊及避免檢測時封閉道路造成之交通阻塞已成為一大課題，本研究首先藉由比較各種鋪面平坦度指標以及儀器之適用性，來提供建議給予有關單位作為參考。 並且由比較結果得之，國際糙度指標(IRI)是目前較適用於進行大範圍檢測，以及其所能夠檢測出的波長範圍，是較接近會影響人體對於垂直加速度的感覺，也就是舒適度的一種指標。 儀器設備部分，便改善前一代自行開發之慣性式平坦儀，改採雙輪跡之取樣，增加其路網檢測之可信度，並且比較國內外之慣性平坦儀相關規範，得知國內對於慣性平坦儀在加速度規、位移感測器以及數值驗證方面有部分缺失，建議其改善。 關鍵字:平坦度、國際糙度指標、慣性式平坦儀、中華民國國家標準ABSTRACT Pavement roughness reacts on profile which clearly describes the roughness; the pavement roughness is one of the important indicators for the passengers comfort. Growing in the motor vehicles of the current situation, how to effectively and quickly collect information and to avoid detection when the road closed road caused the traffic jam has become a major issue. The international roughness index (IRI) is more suitable for large-scale testing, and it can detect the wavelength range is closer to the vertical acceleration will affect the human body for the feeling or comfort. This study compares the roughness index and instrument of the applicability to advice given to the unit as a reference. So this study tries to develop the intelligent vehicle for pavement survey by oneself. It can improve the problem which existed in the apparatus of survey roughness. And compare the Specification of inertial profiler, by the results that CNS is no good enough in some part, such as accelerometer, displacement sensors, numerical verification. Key word: CNS, Roughness, Standard of Roughness, inertial profiler
