Influence of Expressway Road-related Widening Construction on Driver's Heart Rate Growth Rate
Based on the road-widening project of Wenzhou East-Tangxia section of Zhejiang Yongtaiwen Expressway,a full-scale vehicle test was carried out.The psychophysiological data of drivers were collected by Physiolab wireless psychological instrument,and the change characteristics of driver's heart rate growth rate index were studied.The results show that the average growth rate and the change interval length of drivers'heart rate in the working area of road-related projects are increased by 16.34％and 20％respectively.Based on the catastrophe theory,the threshold of the safety level of heart rate growth rate is 35％,so it is determined that the risk sections in the road-related construc-tion work area are 200m before entering the road-related engineering work area and 120m after leaving the work area based on the driver's psychophysiological influence.By analyzing and comparing the av-erage and standard deviation of the driver's heart rate growth rate in six sections of the road-related engineering operation area,it is found that the driver's heart rate growth rate changes more obviously in the work area,the upstream transition area and the warning area,and the average value is 18.56％,4.81％and 3.52％higher than the safety level threshold respectively.
