摘　　要：由于高速公路桥隧比例大、道路线形复杂,给驾驶员行车带来了安全隐患,为了提高桥隧路段行车安全性和驾驶舒适性,以速度一致性、小波理论为基础,通过实车试验采集与分析驾驶员的心生理反应参数、速度等数据,得到了心率增长率与速度、照度的变化规律。结果表明,桥梁和隧道车速特性存在明显差异,在桥梁段速度差最大为7.8 km/h;在隧道路段,速度差最大为26.3 km/h,速度协调性差;并通过分析距离与照度、速度、心率增长率的关系提出了桥隧过渡段的最小安全间距的计算方法,为高速公路桥隧路段路线设计和交通安全管理提供了理论参考。This paper aims to improve safety and driving comfort on the sections between bridges and tunnels.The paper collects the driver’s physiological response parameters,speed and other data through actual vehicle tests,and analyses the safety distances between bridges and tunnels on highways based on the driving behaviors from the data collected.The main content of the paper is as follows.Firstly,the paper introduces wavelet theory.The paper argues that when the driver’s heart rate is used as the physiological response parameter,a noise reduction method is required.This method is chosen to reduce the noise of the original signal and to make the periodicity of the heart rate signal more apparent.The use of appropriate data processing methods will effectively reduce the difficulty of data analysis and increase the efficiency of analysis.The paper then presents some real-life experiments based on actual sections between bridges and tunnels.For the bridge and tunnel sections,data on speed,heart rate increase and lighting levels are collected.These data form the basis of the subsequent analysis of the driver’s physiological response parameters.This method of experimentation can be further applied to testing the physiological response parameters of drivers on other roads.The paper again analyses the relationship between heart rate increase and illumination at the tunnel entrance and obtains a model of the relationship between the heart rate increase and the illumination change rate.It also analyses the speed characteristics of the sections between bridges and tunnels and obtains a model of the relationship between driver heart rate increase and speed on these sections.These models will be useful to stakeholders in determining whether it is safe for vehicles to travel on the sections between bridges and tunnels.Finally,the paper proposes a calculation method for the safe distance of the transition sections between bridges and tunnels with different connection forms based on a comprehensive consideration ofspeed and hea
