Abstract

The purpose of this study was to investigate the effective use of stanchions and handrails in buses. We constructed experimental equipment resembling bus stanchions and handrails and examined the grip and hold strength exerted when used. The total number of subjects was 80: 30 elderly and 19 young males, and 22 elderly and 9 young females. The experimental equipment comprised four parts: a handle part to imitate safety devices in buses such as stanchions, handrails, and straps, which was pulled by a winch at a constant speed; and a load cell wired with an analyzing processor, which output the strength exerted. The handle part was designed to measure grip and hold strengths against pulling forces in three directions, that is, forward, in the direction of the back of the hand, and in the direction of the palm. The subjects were asked to grasp the handle part against a pulling force. The maximum grip and hold strengths were recorded and analyzed. The strengths when pulled forward were the largest independent of the sex and age of the subjects. The results indicate that standing bus passengers should grip the fixtures, such as a stanchion, with their right hand when they are standing on the right side in a bus facing the windows.
