非號誌化路口違規駕駛行為影響因素之研究

An Investigation of Factors Influencing Driving Violation Behaviors at Non-signalized Intersections

駕駛者行經非號誌化路口，常因未能減速慢行或禮讓路權優先方向的車輛先行實而導致交通事故的發生。了解非號誌化路口的違規駕駛行為，有助於研擬改善策略，以降低路口的肇事率。本研究依據道路交通法規中有關非號誌化路口的條文，衡量非號誌化路口的違規項白，並設計駕駛戚受問卷及運用攻擊性及刺激尋求量表，抽樣訪問調查218位駕駛者。驗證性因子分析將問項縮減成六個構面。非號誌化路口違規項目分為停等、禮讓及方向性等三個違規傾向構函。衡量駕駛者攻擊傾向的攻擊性量表，產生身體攻擊及忿怒兩個構面。駕駛戚受為單一構函，衡量駕駛者行經非號誌化路口，因必須停等或減速而戚到不耐煩或浪費時間的程度。結構方程模型的校估結果發現，駕駛者行經非號誌化路口，因停等、減速等動作，容易嵐到不耐煩與浪費時間者，較會產生違規行為。身體攻擊性強的駕駛者，容易產生不減速、不禮讓的違規行為。年輕與男性駕駛者在非號誌化路口有較高的違規傾向。本文最後提出改善建議，以供相關主管機關參考。

Traffic accidents often occur at non-signalized intersections because drivers are driving too fast or fail to yield right-ofway. Understanding driving violation behaviors at non-signalized intersections enables us to develop strategies to reduce accident rates. This research adopted traffic code associated with violations at non-signalized intersections to measure how often drivers commit driving violations. A questionnaire survey which includes the collection of driving perception, an aggression scale, a sensation-seeking scale together with respondent s background information was conducted with a sample of 218 drivers. Results of confirmatory factor analysis consist of six constructs. Driving violstion behaviors at non signalized intersections include stop, yield and directional dimensions. Aggressive driving behaviors include physical and anger dimensions. Driving perception which measures the propensity to be impatient when driving through α non-signalized intersection is an one dimensional scale. The estimation results of the structural equation models indicate that drivers who feel impatient and wasting time for stopping at non-signalized intersections are more likely to commit driving violations. Drivers with strong physical aggression may lead to violations offailure to stop at stop sign or to yield right-of-way.. Young and male drivers also have high tendency to commit driving violations. Finally, suggestions for improving traffic safety at non-signalized intersections are proposed.
