Road accidents in Malaysia especially involving motorcyclists are incredibly alarming. As a result, our country has been suffered significant losses, especially in terms of human capital. Therefore, comprehensive and effective efforts must be taken by all parties, either government or private organizations, to address these critical issues. Malaysian Institute of Road Safety Research (MIROS), as the leading institution that focuses on road safety research in Malaysia, has developed a mobile application approach as one of the initiatives to overcome the problem. This paper highlights the development of the mobile application that be able to measure safe riding behaviours among motorcyclists, which then called as Safer Riders Behavioural Scores (SCORES). The development involved the identification of four variables that contribute to safe riding behaviours, which were stress, fatigue, situational awareness, and hazard perception. The process of measurement, integration, analysis, and results display of the identified variables were performed by the SCORES mobile application. The main page of SCORES contains evaluation components (i.e., rider details and all four variables) and information icons (i.e., contact us, application details, additional participants, main page, participant list with scores, server setting, and user profile). All the recorded data can be accessed and downloaded from the secured server for further data analysis. It is hoped that the SCORES will give benefits to society, particularly motorcyclists for road safety betterment in Malaysia.
