臺灣內政部營建署每年邀請專家學者對當地政府所管養之人行環境進行檢查與評估，本研究目的為建立人行環境調查車(Pedestrian Sidewalk Inspection Vehicle, PSIV)以評估人行道狀況，導入WPRI (Wheelchair Pathway Roughness Index)與垂直加速度，WPRI為ASTM E3028所定義人行道粗糙度之指標，並參考ISO 2631-1定義加速度對人體振動衝擊警戒區，更進一步將人行環境調查車進行驗證，並對國立中央大學校園內之各種人行道路面進行評估，同時量測人行道路面之抗滑能力。人行環境檢測車驗證結果符合ASTM E3028之設備要求，並可檢測人行道路面之垂直加速度。根據WPRI檢測結果顯示各人行道路面狀況具有顯著差異，其中以瀝青混凝土鋪面與人造面磚之表現為佳，且WPRI與人行道鋪磚間距具高度正相關性。WPRI為人行環境粗糙度之指標，而垂直加速度為評估振動狀況之指標，根據本研究結果顯示兩者為低度相關性。綜合研究結果可顯示搭載WPRI與垂直加速度之人行環境檢測車為具有評估人行道路面狀況之設備，有助於協助當地政府與工程師提高殘疾人士、孕婦與年長者所使用之人行道路面服務品質。;Inspection and evaluation the pedestrian sidewalk of the local government with experts and scholars is the annual program of construction and planning agency ministry of the interior in Taiwan. the objective of this study was established a pedestrian sidewalk inspection vehicle to evaluate the pedestrian sidewalk. The Pedestrian Sidewalk Inspection Vehicle (PSIV) was integrated by Wheel Pathway Roughness Index (WPRI) and the Accelerator. The WPRI was following ASTM E3028 to evaluate the roughness and Accelerator was referenced of ISO 2631-1 to the vibration shock caution zones of human body in this study. The verification of PSIV would be also conducted, and PISV would be adopted to evaluate various pedestrian sidewalk pavement in National Central University Campus. In addition, the friction of various pedestrian sidewalk pavement would be also measurement. The verification results of PSIV were matched the equipment of ASTM E3028 and it could be detecting the vertical vibration from pedestrian sidewalk pavement condition. Based on the results of WPRI, the difference of various pedestrian sidewalk pavement was significance, the asphalt concrete and artificial facing bricking were the best pedestrian sidewalk pavement. The relationship between WPRI and pedestrian sidewalk brick pavement gap was positive high correlative. The WPRI is the index of pedestrian sidewalk roughness, the vertical accelerator is index of vibration and the relationship between WPRI and vibration was low correlative in this study. Based on above, the PSIV with WPRI and vertical accelerator should be a very nice equipment to inspect and evaluate pedestrian sidewalk pavement. Under the assistance of PSIV, it should be helpful for local government and engineers to raise the service level of pedestrian sidewalk pavement for disabled, handicap, pregnant and elder. This study is worthy of further studying to improve our infrastructure in Taiwan.
