The Study of Ingress and Egress for Medium Commercial Vehicle Driver Using 3D SSPP

This study was conducted to evaluate the various postures of commercial vehicle drivers. There are a lot of modern in-vehicle. There are many research and development. But most of the passenger in-vehicle is a study. Is a lack of research on commercial in-vehicle. The participants of this study consisted of 20 adult males with at least one year of driving experience. The postures analyzed were split into three sub-categories based on the primary category of ingression or egression. The specific postures for ingression were grip, step, and body lift while the postures for egression were body twist, body lowering, and step. The experimenter utilized 3D SSPP to discover the strain and workload to the body from the postures. Therefore, we analyzed this work load based on the most common physical postures of the participants. The results showed that in regards to ingression, the body lift had the most strain when the distance between the grip and the following step was increased. Furthermore, as the height of the grip was increased, the shoulder and elbow workload was increased as was shown by the increased 3D SSPP value. In addition, as the height of the ground of the vehicle increased, the strain on the elbow increased. This study was aimed to define ingression and egression postures most suitable for a convenient and efficient environment as well as to set a standard for further research into this field.
