由於年輕人機車事故嚴重，本研究針對年輕人發展一個手機機車駕駛遊戲系統，以路口「讓」為主要學習主題，設計相關學習情境於不同的遊戲路線中，並進行學習成效評估。學習成效評估包括以問卷方式評估學習者之機車安全知識認知程度，另利用遊戲過程的騎車行為記錄資料評估分析學習者駕駛行為之改變。機車安全知識的前後測問卷與駕駛行為資料之分析結果顯示，受測者在機車駕駛遊戲學習前對於讓路權之相關標誌、標線、號誌以及路權法規規定的知識程度皆不足。透過手機駕駛遊戲系統學習後，受測者的機車安全知識認知程度明顯提升，也可導正錯誤駕駛行為，利用手機駕駛遊戲讓年輕人學習機車安全駕駛知識和正確行為是一值得發展的教育方式。

In Taiwan, there are a large number of motorcycles, and on average every 1.7 persons have a motorcycle. There were numerous motorcycle accidents. Nearly 90% of all traffic accidents involved motorcycles. Motorcyclist safety education thus is an important issue. Considering the severity of young motorcyclist accidents, this study aims at developing a motorcycle riding game system on a smartphone platform; yielding right-of-way at intersections is chosen as the main learning theme. Various learning scenarios related with yielding right-of-way were designed on different game routes and a mechanism for evaluating learning performances was developed. The evaluations of learning performances included knowledge of motorcycle safety using questionnaires; in addition, the riding behaviors in the game were recorded for investigating the changes of learners’ riding behaviors. A total of 52 young subjects were recruited in the study. The analysis results of the pre-questionnaires and post-questionnaires of motorcycle safety knowledge and riding behaviors showed that the participants did not have sufficient motorcycle safety knowledge regardless of their gender or having a motorcyclist’s license. The participants’ knowledge about the yielding right-of-way related traffic signs, traffic marking, traffic signals, and behavioral rules was insufficient. Learning through the developed motorcycle riding game system significantly improved the participants’ motorcycle safety cognitive knowledge and considerably reduced their incorrect driving behaviors. The results suggest that applying motorcycle riding game to young motorcyclist for learning safe riding knowledge and proper riding behaviors is an educational approach that is worth of further consideration and development.
