Reducing vehicle speed is an important element to improve driving safety. In order to reduce the speed, various traffic calming devices are used in places such as communities and schools. This study proceeds in two steps. First, the influence of speed, traffic calming devices and seating position on vertical acceleration was measured. Secondly, the influence of different factors on passengers’ riding perception was investigated. There are 35 participants including 20 males and 15 females. ANOVA analysis was used.
It was found that vertical acceleration and passenger perception is highly correlated. Vertical acceleration and passenger perception in various speeds, traffic calming devices and seating position are significantly different (P<0.001). Vertical acceleration and passenger perception in gender are not found significantly different. However, they are significantly different in age cohort. The faster the speed, the smaller the vertical acceleration was discovered at specific calming device. It is therefore recommended that the most comfortable passing speed is 20 km/h. |
