交通安全的「3E」係指透過教育（Education）、工程（Engineering）與執法（Enforcement）三個途徑，來增強道路安全的目標。交通安全教育宣導媒材，長期以來都是以傳統的大眾傳播媒介為主，像是圖片、海報、文宣手冊、電視廣告片等。這些交通安全宣導媒材，在數位匯流（digital convergency）條件下，已經出現新工具的現象，亦即業餘人士有能力與技術可以自製微電影，並且上傳至社群網站公開供人流灠，以進行交通安全宣導。本研究探討自製交通安全微電影的實況，並以實際案例介紹製作交通安全宣導微電影的過程。自製交通安全宣導微電影，可以使教育宣導媒材更為多元化，內容也可以更為生動活潑，若能妥善加以運用與推廣，預期可以節約費用、擴大宣導效果，並且追求更為安全、順暢的道路交通安全治理目標。

The traffic security ＂E3＂ mean to use education, engineering and law enforcement to make the road save. For long time, we traditionally used information data to make propaganda on traffic safety with students, like picture, poster, manual, and short movies. This traffic safety propaganda tools can be see a new with the digital convergences, and students can make short film by themselves, and using it online to show it to everybody, so they make themselves propaganda. Our research discuss on students’ short film making situation, and explained short film through cases. In research, we state that official bureau can encourage students to create short film on traffic safety; it can make the education more active and ameliorate the conscious of student on traffic safety because of teamwork.
