從臺北市自行車安全分析探討都市街道改善策略之研究 / An Improvement Strategy of Urban Streets According to the Bicycle Safety Analysis in Taipei City

劉秉宜, Liu, Pin Yi Unknown Date (has links)
過去都市的發展與道路規劃多以汽機車為主體,對於自行車的騎乘環境相對不夠友善,而隨著近年國內自行車使用率逐年攀升,據資料指出自行車發生事故的機率也有提高的趨勢,顯示自行車於道路上之安全性考量更需重視。故本研究將針對台北市自行車肇事資料進行深入探討,找出影響肇事嚴重度之因素,進而從規劃設計面研擬降低自行車事故之改善策略。 本研究係以民國98年至102年台北市自行車事故資料為分析對象,將肇事嚴重程度分為「死亡或頭部受傷」、「人員受傷」及「未受傷」三類,同時根據文獻回顧及實務上所能取得之資料,蒐集人、路、環境等24項研究變數。首先透過統計分析了解肇事資料之特性,而後再以多項式羅吉斯迴歸模型,分別針對整體事故以及不同空間及不同事故型態之自行車肇事資料,建構自行車肇事嚴重度模型,以釐清影響自行車事故之主要因素。 研究結果顯示,道路因素中事故位置為路口及路段對於自行車事故皆有顯著影響,其中路口造成死亡或受傷之機率更高;環境因素中,因彎道或建物造成視距不良對於增加自行車事故亦有顯著影響,而坡道則會降低事故發生之機率;在人的因素中,18歲以下和年齡越大、酒駕、直行或右轉,皆會增加因自行車事故致死或受傷之機率。最後依據實證之結果,謹從交通管理中的3E政策-交通工程(Engineering)、交通教育(Education)及交通執法(Enforcement)三面向之觀念及角度帶入都市設計層面,提出道路及環境改善措施,以提升都市街道之自行車騎乘環境,並透過教育宣導、推廣活動及相關法令規範等配套措施,藉以增加自行車之騎乘安全。

面臨颱洪災害下家戶風險溝通與調適行為之研究 / A Study of Flood Disaster Risk Communication and Adaptive Behavior for Household

陳郁筠 Unknown Date (has links)
隨著氣候變遷與溫室效應影響日益明顯,台灣近年發生極端強降雨颱風的次數越來越頻繁,更造成流域地區嚴重災情,而從莫拉克風災經驗可體會到家戶風險溝通的重要性,也意識到我國實務與學術上相關研究的缺乏,故本研究探討家戶風險溝通機制中各項重要因素與調適行為間的關係,以及找出影響家戶調適行為決策之關鍵因素,進而提出家戶風險溝通策略之改善建議,以促進家戶採取調適行為。 本研究經由文獻回顧建立家戶調適行為之風險溝通概念架構,依循此架構研擬問卷,以高屏溪流域地區家戶為研究對象進行問卷調查,透過結構方程模式(SEM)驗證風險溝通架構,了解風險溝通機制各項因素與影響調適行為各因素之關係,後以面對災害回應之強烈將調適行為積極程度分為「消極或低度積極」、「中度積極」與「高度積極」,運用多項式羅吉斯迴歸模型建立家戶應變措施決策模型與調適措施決策模型,找出影響家戶調適行為決策之關鍵因素。 研究結果顯示,調適行為受到內在認知的影響,而內在認知同時受風險溝通機制與外在環境之影響,就風險溝通機制而言,親友鄰居、村里長與地方政府等社區網絡為重要管道。影響調適行為之關鍵因素以災害認知為主,其次為調適行為認知,居住村里次之,其中災害認知與調適行為認知越高,越有可能採取較積極之調適行為,此外,由於自然社會環境、風險溝通特性與社會經濟背景等因素交互影響下,各村里在調適行為決策上也有所差異。最後依據實證結果,與水患自主防災社區風險溝通現況,提出改善家戶風險溝通之策略建議,期望增進風險溝通機制的完備與促進家戶採取調適行為,以減緩極端氣候造成的衝擊。 / Along with the intensification of global climate change and greenhouse effect, typhoons with extreme rainfall strike Taiwan more and more frequently, which cause severe disasters in watershed area. From the experience of Typhoon Morakot in 2009, we realized the importance of risk communication with households and also the lack of related academic research. As a result, this study aims to discuss important factors in risk communication mechanism and their relationships with adaptive behaviors. It also find out key factors influencing decision-making of adaptive behaviors. Based on literature review, this study build a conceptual framework of risk communication process to describe how to trigger adaptive behaviors and encourage adaptive behaviors with risk communication. This study send out questionnaires to the households in Kaoping River Watershed and use structural equation modeling(SEM) to verify the conceptual framework. Then according to attitude of positive degree, adaptive behaviors are classified into“passive or low”,“medium” and “high” levels. By multinomial logistic regression, an empirical analysis was performed to analyze the key factors influencing decision-making of adaptive behaviors. The results show that adaptive behaviors are affected by internal cognition and at the same time internal cognition are affected by risk communication mechanism and external environment. As for risk communication mechanism, family, friends, neighbors and local governments are crucial communication channel. Key factors influencing decision-making of adaptive behaviors are cognition of disaster and adaptive behavior. People with higher cognition of disaster and adaptive behavior would more likely to take positive adaptive behaviors. Besides, community they lived in is also a key factor. Because the interaction of environments, risk communication patterns and socioeconomic attributes, people from different communities would take different adaptive behaviors. Based on empirical results, this study propose suggestions of risk communication strategies in order to better the risk communication mechanism and encourage households to take adaptive behaviors.
