Abstract: Real-time exposure air monitoring is essential to protect the respiratory health of the Malaysian traffic police. However, the data from monitoring stations have been inadequate to provide accurate information about their exposure. This report describes the conceptual design of a wireless exposure indicator system, and then evaluates the field performance of the system by collocation. The study tested the accuracy of particulate matter size 2.5 (PM2.5), carbon monoxide (CO), and nitrogen dioxide (NO2) by comparing the measurements from the prototype with the measurements from reference instruments. The field testing found that the data tested were significantly correlated with each other (PM2.5-rs = 0.207, p = 0.019 NO2-rs = 0.576, p = 0.02 and CO-rs = 0.545, p = 0.04). The prototype proved to be successful as it can compute and transmit real-time monitoring data on the level of exposure to harmful air.

Abstract: Motorcycle is getting significant attention as it is already and will be an important mode of transport in the future. However, motorcycle is a hazardous type of vehicle mode and therefore requires more efforts to enhance their safety and comfort level. As compared to car drivers, motorcyclists are more exposed to sitting hazards during the riding process. Due to increased exposures to seated postures, sitting comfort has become an important issue that demands adequate ergonomic interventions. The purpose of this study was to evaluate the effectiveness of new model of motorcycle seat with lumbar support aimed at reducing muscle discomfort among male motorcyclists. This study was conducted among male motorcyclists at University Putra Malaysia (UPM). 94 subjects were participated, with 47 subjects for each control and experimental group. Each subject was asked to sit for 2 hours on motorcycle in two different sessions. At every 15 minutes interval, subjects were required to evaluate their discomfort level on Borg’s scale CR-10 questionnaire. Results in this study found that lumbar support (prototype) shows a significant effect towards certain body parts particularly on the neck, shoulder, upper back, arms and also lower back. However, there were no significant effect were found on the buttock, thigh, knee, calf and ankles. In conclusion, this new model of motorcycle seat with lumbar support can help to reduce discomfort level towards motorcyclists especially during prolonged riding process.
