國際標準組織為降低全球道路交通事故死傷人數，於2012 年推出道路交通安全管理系統ISO 39001 之標準，雖不少研究指出其可以為國家、組織及民眾帶來效益，但鮮少研究探討組織導入此系統的意願以及其影響因素。因此，研究企圖發展量表，評估業者執行道路交通安全管理之能力、態度、對利害關係人反應感受與執行意願，以計畫行為理論建構導入此系統的意願與其影響因子之關係。研究發現業者的執行能力、態度與對利害關係人反應之感受皆與執行意願呈顯著正相關，又以對利害關係人反應之感受最為關鍵。一般而言，客運業者具有顯著較高的執行之意願、執行之能力、推動之態度及對利害關係人反應之感受。研究之成果可以提供主管機關擬定道路交通安全管理政策之參考。

Not only do traffic crashes bring about a wealth of agony and loss, but also they can put countries and societies in jeopardy. International Standard Organization (ISO) has developed ISO 39001 road traffic safety management system (RTSMS) to reduce fatalities and serious injuries due to traffic crashes since 2012. Although there are lots of compelling evidences which prove this safety management system can actually benefit countries, organizations and people, seldom research discusses the intention of implementing the system and the influencing factors. Hence, this study aims to develop effective scales to evaluate motor carriers’ abilities, attitude, subjective norm and intention in terms of RTSMS. Moreover, this study also constructs the relationships between intention and influencing factors based on Theory of Planned Behavior (TPB).The study result manifests that abilities, attitude and subjective norm are positively and significantly correlated with intention and subjective norm is the most influential one. Generally speaking, the result shows that passenger carriers have significantly higher intention, abilities, attitude and subjective norm to implement RTSMS than freight carriers. The study result can assist the government to make administrative policies of RTSMS.
