Information architecture & mathematical modelling to optimally 'fit' human operator on motorcycle / Muhammad Izzat Nor Ma'arof

Code (2010) noted that motorcycles road accidents are always due to human error. Based on Stedmon (2010), it is strongly suggested that when the human operator's working posture does not 'fit' the motorcycle, the human operator is prone to human error and possibly accident. Therefore,...

Based on Stedmon (2010), it is strongly suggested that when the human operator's working posture does not 'fit' the motorcycle, the human operator is prone to human error and possibly accident.

This study aimed to establish new motorcycle ergonomics information architecture from existing ergonomics knowledge for the establishment of new mathematical model to optimally 'fit' human operator on motorcycle. The motorcycle information architectures established were the Motorcycle Risk Information Architecture (MORIA) and Riding Posture Analysis Components (RIPAC) (consisting of RIPEC, HUMIS and RIPOC).

The methods used in validating the Bologna Triangle were working posture ergonomics assessment, biomechanical analysis and experimental research design. The experimental research design was a surface electromyography (sEMG) bilateral measurement of 4 muscle groups extensor carpi radialis longus (forearm muscle), upper trapezius (shoulder/neck), triceps (upper arms), and deltoid (shoulder)). 8 subjects participated voluntary for the experiment. The triangulation between the three validation methods showed that the proposed optimal 'fit' riding posture (specific for a particular subject) showed the lowest physical static loading distribution, working posture hazard score and total body muscular activation.
