高齡機車騎士左轉未讓問題及改善策略探討

高齡機車騎士未依規定讓車事故嚴重，且我國目前的交通改善策略大多使用警政署事故資料進行分析，僅能得知事故嚴重的肇因為未依規定讓車，並無法得知未依規定讓車的事故狀態。因此本研究使用交通部公路總局覆議會事故資料，利用覆議會事故資料中的事故影片及事故現場圖了解高齡機車騎士未依規定讓車的事故狀態，並實地調查了解號誌化路口左轉設施的設置問題及以焦點團體討論探討高齡機車騎士於號誌化路口左轉的行為。綜合以上分析結果，了解交通安全需要改善的重點，提出交通工程及交通安全教育改善策略，並評估交通安全教育改善策略的成效。研究結果發現，不論是兩段式左轉路口或可直接左轉路口，高齡機車騎士常見之未依規定讓車事故類型皆為外側車道直接左轉，且研究結果發現高齡機車騎士外側車道直接左轉的原因係對於相關標誌、標線及號誌以及相關的路權法規皆不慎了解，以及部份工程設施設置問題所致；而透過教案學習有助於高齡機車騎士學習正確駕駛行為。

Elderly motorcyclists who fail to yield as required by regulations cause severe accidents, and currently, most of Taiwan's traffic improvement strategies are based on accident data from the National Police Agency. This only allows for understanding that the root cause of severe accidents is the failure to yield as required by regulations, but not the specific circumstances of accidents caused by this failure. Therefore, this study used accident data from the Highway Reconstruction Council of the Ministry of Transportation and Communications, and utilized accident videos and on-site accident scene maps to understand the specific circumstances of accidents caused by elderly motorcyclists who fail to yield as required by regulations. Additionally, the study conducted field investigations to understand issues with signalized intersections' left-turn facilities and held focus group discussions to explore the behavior of elderly motorcyclists when turning left at signalized intersections. Based on the comprehensive analysis of the above results, the study identified the key areas that need improvement in traffic safety, proposed strategies for improving traffic engineering and traffic safety education, and evaluated the effectiveness of these strategies. The study found that regardless of whether it is a two-stage left-turn intersection or a direct left-turn intersection, the most common type of accidents caused by elderly motorcyclists failing to yield as required by regulations was directly turning left from the outer lane. The study also found that the reasons for elderly motorcyclists' failure to yield in the outer lane were due to a lack of understanding of relevant signage, markings, and signals, as well as relevant traffic regulations and certain engineering facility placement issues. Teaching elderly motorcyclists correct driving behaviors through lesson plans can be helpful in addressing these issues.
