This study develops a Road Safety Index (RSI) for commercial bus with the aim of determining whether the
proposed index can be beneficial to the stakeholders for the purpose of mitigating road accident and promoting road
safety. Five risk factors which include drivers, Vehicle, Task, Hazard/Risk and Road, where three critical factors out of
these factors, were identified as high contributing factors (Drivers, Vehicle and Road) were selected for the construction
of RSI. Drivers risk perceptions data were collected using survey instrument with sample size (n= 465) to test the
model and the data fits the model perfectly. The main benefits of this approach and the subsequent development of
RSI are: (1) Enable organisations to justify the investment on road safety by providing a measurement and evaluation
mechanism. (2) The index provides a balanced view of the impact of the three critical (DVR) risk factors that the
management can improve upon.
The increase in Musculoskeletal Disorders (MSDs) cases in the context of manufacturing industry in Malaysia in
the recent years has become a national concern. Therefore, the study aims to compare the severity of the WMSDs cases
involving electronic workers by using survey, interview, observation and experimental methods. The questionnaire
was designed and distributed to 204 assembly workers performing printer and inserting semiconductor in the electronic
sector. The ergonomic risk was assessed through direct observation of workers’ posture at their workstation using
WERA. In addition, Electromyogram (EMG) analysis was used to measure the muscle activity of workers. The result
shows that standing workers are exposed to consistent MSD more than sitting workers in all body regions except for
the upper back. According to WERA results, both postures contribute to high risk of MSD especially at wrist and leg
regions. In conclusion, there is a significant correlation in the findings from the survey, observation and EMG analysis
about the prevalence of MSDs among the workers, although the degree of prevalence differs in some body regions.
Hence, there is a need to identify more interacting variables associated with the problem.
