以運動攝影機輔助台北市人行道環境評估

Abstract

近年來，改善台灣的人行道環境成為政府的重要課題，由於台灣的人行道環境普遍不理想，甚至被批評為行人地獄。為了解決這個問題，本研究以營建署的人行環境考評為基礎，目標為消除考評的不客觀性，使其更貼近民眾的需求，並希望該考評能夠實際督促各縣市改善人行道環境。研究選擇了台北市作為研究區域，因為該城市的人行道發展相對成熟，期望透過對台北市的研究成果，為改善全台灣的人行道環境作出貢獻。 為了消除考評的不客觀性並使其更貼近民眾的需求，本研究以運動攝影機輔助人行道環境評估，同時探討營建署的人行環境考評與民眾觀感之間的差異。本研究選擇特定的人行道樣本，以AHP層級分析法的民眾問卷調查為基礎，分析人行道環境的四個主要屬性：暢行性、舒適性、安全性和使用性。在評估使用性方面，本研究使用地理資訊系統（GIS）作為輔助工具，同時進行民眾問卷調查以了解人行道的舒適性。 研究結果顯示，在AHP民眾問卷方面，民眾對人行道的安全性最為關注，其次是暢行性、使用性和舒適性。然而，民眾對暢行性的關注程度低於營建署的評估結果約10.1個百分點，對舒適性的關注程度則高於營建署的評估結果約9.7個百分點。 另外，研究結果還顯示運動攝影機的評估方式是可行的，它能夠快速且相對客觀地計算分數，同時消除了天氣的影響，並且能夠讓評估委員進行遠距作業。而GIS和民眾舒適度問卷更能夠反映真實情況，並提供更準確的評估結果。

In recent years, the government has recognized the improvement of Taiwan's pedestrian environment as a critical issue due to the generally unsatisfactory conditions, even earning the label of "living hell" for pedestrians. To address this problem, this study is based on the evaluation of pedestrian environments by the Construction and Planning Agency (CPA), aiming to eliminate the subjectivity in the evaluation process and make it more aligned with the needs of the public. It is hoped that this evaluation can effectively encourage various cities and counties to improve their pedestrian environments. Taipei City was chosen as the research area due to its relatively mature development of pedestrian infrastructure, with the expectation that the research findings in this city can contribute to the enhancement of pedestrian environments across Taiwan. To achieve the goal of eliminating subjectivity in evaluations, this study employs the use of action camera to assist in the assessment of pedestrian environments while examining the disparities between the evaluations conducted by the Construction and Planning Agency and the perceptions of the general public. Specific samples of pedestrian pathways were selected for analysis, and a questionnaire survey based on the Analytic Hierarchy Process (AHP) was conducted to investigate four major attributes of pedestrian environments: walkability, comfort, safety, and usability. In assessing usability, the study utilizes Geographic Information Systems (GIS) as an auxiliary tool and conducts a questionnaire survey to explore the comfort of pedestrians. The research results indicate that, according to the AHP surveys conducted among the public, safety is the primary concern for pedestrians, followed by walkability, usability, and comfort. However, the public's emphasis on walkability was about 10.1 percentage points lower than the CPA's evaluation, while their emphasis on comfort exceeded the CPA's evaluation by approximately 9.7 percentage points. Furthermore, the study demonstrates the viability of using action camera for evaluation, as they enable rapid and relatively objective scoring, while mitigating the influence of weather conditions, and facilitating remote assessments by evaluators. In comparison, the use of GIS and the survey on public comfort levels provide a more accurate reflection of the actual situation and offer more precise evaluation results.
