. The main purpose of this research study was to evaluate changes in fatigue, stress and vigilance amongst commercially licensed truck drivers involved in a prolonged driving task. The secondary purpose was to determine whether a new ergonomic seat could help reduce both physical and cognitive fatigue during a prolonged driving task. Two different truck seats were evaluated: an industrial standard seat and a new truck seat prototype. . Twenty male truck drivers were recruited to attend two testing sessions, on two separate days, with each session randomized for seat design. During each session, participants performed two 10min simulated driving tasks. Between simulated sessions, participants drove a longhaul truck for 90 min. Fatigue and stress were quantified using a series of questionnaires whereas vigilance was measured using a standardized computer test. . Seat interactions had a significant effect on fatigue patterns. The new ergonomic seat design holds potential in improving road safety and vehicle accidents due to fatigue-related accidents.
. 本研究的主要目的是评估参与长时间驾驶任务的商业许可卡车司机的疲劳、压力和警觉性变化。次要目的是确定新的人机工程学座椅是否有助于减少长时间驾驶任务中的身体和认知疲劳。评估了两种不同的卡车座椅：工业标准座椅和新型卡车座椅原型。. 招募了 20 名男性卡车司机参加两次测试，分别在两天进行，每次测试的座椅设计都是随机的。在每次测试中，参与者都进行了两次 10 分钟的模拟驾驶任务。在模拟测试之间，参与者驾驶长途卡车 90 分钟。使用一系列问卷来量化疲劳和压力，而警觉性则使用标准化的计算机测试来测量。. 座椅交互对疲劳模式有显著影响。新的人机工程学座椅设计有望通过减少与疲劳相关的事故来提高道路安全和车辆事故的安全性。
