逆行非机动车骑行者的安全生理学特性

Safety physiology characteristics of bicyclists on reverse riding conditions

为减少非机动车逆向骑行对道路交通流的影响,提升道路安全水平,研究逆行非机动车骑行者的安全生理学特性。通过高精度摄像机获取西安市3个道路断面的非机动车逆行比例,利用运动手环及手机监测骑行者逆行时的速度和心率,应用时域分析法对比分析骑行者逆行与正常骑行时的心率变异性(HRV),并提出改善管控措施和优化交通设施设计等引导骑行者健康安全骑行的建议。结果表明:电动自行车逆行数量大,而自行车逆行率高;逆行时骑行者的行驶速度和HRV降低、心率升高,造成交感神经张力增加,不利于骑行者健康及交通安全。

The safety physiology characteristics of bicyclists on reverse riding conditions were studied for the purpose of reducing the influences of reverse riding on traffic flow and health condition of bicyclists,and improving roadway safety. High-resolution video cameras were utilized to obtain the proportion of reverse riding vehicles at three arteries＇ cross sections in Xi＇an. The fitness wristband and cellphone were utilized to measure the riding speed and heart rate of the bicyclists. The time-domain theory was applied to compare the HRV characteristics between common and reverse riding. Corresponding improvements on reverse riding,including appropriate traffic management and control measures and the optimization of traffic facilities,were also provided to lead healthy and safe riding. The results indicate that there are more electrical reverse riding bicycles,however the traditional bicycle has a larger proportion of reverse riding.Reverse riding will lead to lower riding speed,higher heart rate and lower HRV,which may cause the sympathetic nerve hypertonia and be harmful to bicyclists.
