The purpose of this study was to integrate mobile communication technologies and a global positioning system (GPS) to construct an instant, convenient report of the mobile network service system named the Mobile Traffic Violation Reporting System (MTVRS), to improve learners' traffic violation reflection level. Data were collected using a "usefulness of mobile learning systems" questionnaire and traffic violation reflection questions from a sample consisting of 32 learners in Taiwan. Learners voluntarily participated in a four-week program using mobile devices to transmit photographs of local traffic violations and exchange pictures and observations. The experimental results revealed by the questionnaire were satisfactory and encouraging in terms of the effectiveness of the supported mobile learning environment. Moreover, the responses to the questionnaire showed significant differences in regard to both gender and age. The study also found a positive improvement in reflection levels toward traffic violations among groups following the experiment. (Contains 7 tables and 5 figures.)
