摘　　要：为了研究山地城市立交出入口前后驾驶员心理负荷变化特点及其影响因素,选取重庆市3座立交开展实车试验,用车载仪器记录连续自然驾驶状态下的车速、道路环境及驾驶员心率(heart rate,HR)等数据,分析驾驶员性别、驾驶风格、立交出入口类型、交通量等因素对驾驶员心理负荷的影响。研究发现:1)入口前后,女性驾驶员HR更稳定;出口前后,男性驾驶员HR更稳定。2)冒险型驾驶员的心理负荷远高于愤怒型与焦虑型驾驶员,愤怒型与焦虑型驾驶员心理负荷相近。3)入口处采用平行式变速车道时的驾驶员心理负荷更低;出口处采用直接式变速车道时的驾驶员心理负荷更低。4)驾驶员心理负荷随交通量的增大而增大,大流量状态下,驾驶员在出口处的心理负荷略大于入口处的心理负荷。In order to study the characteristics and influencing factors of the drivers’psychological load changes before and after the entrances and exits of the mountain city interchanges,three interchanges in Chongqing were selected to carry out real-vehicle experiments,and on-board equipment was used to record data such as vehicle speed,road environment and driver heart rate(HR)under continuous natural driving conditions.The influence of factors such as the drivers’gender,driving style,overpass type,traffic volume on the drivers’psychological load were analyzed.The study found that:1)The female drivers’heart rate was more stable before and after the entrance;the male drivers’heart rate was more stable before and after the exit;2)The mental workload of adventurous drivers was much higher than that of angry and anxious drivers,and the mental workload of angry and anxious drivers was similar;3)The mental workload of drivers using parallel shift lanes at the entrance was lower,and the mental workload of drivers using direct shift lanes at the exit was lower;4)The mental workload of the driver increased as the traffic volume increases;Under high traffic conditions,the mental workload of drivers at the exit was slightly greater than that at the entrance.
