| 摘 要： | 桥头跳车现象影响了驾驶舒适性和行车安全性．通过调查统计和驾驶行车实验，发现驾驶员心率的变动和行车加速度与桥头跳车严重程度有明显的相关性，可作为桥头跳车对行车安全影响的评价指标．研究结果表明，跳车严重时驾驶员心率比驾驶稳定心率增加了10次．min^-1以上，加重了驾驶员的心理生理负担，对行车安全产生了较大影响．

| Abstract: | Vehicle bumping at bridge-head directly affects traveling comfort and safety.Investigative statistic and driving experiment indicate that heart rate 's variation and driving acceleration of vibration have obvious relativity to the degree of vehicle bumping at bridge-head,and can be regarded as the evaluation indexes of the impact of vehicle bumping at bridge-head on the traffic safety.The research result denotes that the driver's heart rate,compared with steady driving heart rate,increases more than 10 times per minute with serious bumping,it leads to driving strain and has considerable harm to driving safety. |

| Keywords: | vehicle bumping at bridge-head heart rate acceleration of vibration evaluation index |
