生理负荷在公路线形设计评价中的应用研究

系统的提出了生理负荷在公路线形设计评价中的理论和操作的具体方法,利用计算机仿真技术将道路交通环境进行可视化,然后让驾驶员使用驾驶模拟器在虚拟交通环境中驾驶,通过眼动仪和生理测试仪实时采集驾驶员的注视点、注视持续时间、瞳孔面积、脉搏、皮电、体温、轨迹、速度等生理数据,同时采集车辆的速度和行车轨迹等数据,通过模糊综合评价找出人、车、路不协调的突变点,认为是事故易发路段,分析其原因并且在设计中加以改进,通过设置循环和判定可以有效提高道路的行车安全性。

Research on Applied of Physiological Load in the Evaluation of Highway Alignment Design

This paper propose a methods and implementation of the applied of Physiological load in the evaluation of highway alignment design,firstly,made the road environment visualization use the computer simulation technology,secondly,let the driving simulator driving in the virtual traffic environment,at the same time use the eye tracker system and physiological tester collection the driver＇s fixation point,gaze duration,pupil size,pulse,galvanic skin,body temperature,Trajectory,speed and other real-time physiological data,then find the uncoordinated mutation between people,vehicles and roads consider as accident-prone sections by Fuzzy comprehensive evaluation,finally analyze the reason and how to improvement in design,By setting cycling and the exit conditions can effectively improve the safety of roads design.
