【摘要】：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。
[Abstract]:In order to reduce the influence of non-motor vehicle reverse riding on the road traffic flow and improve the road safety level, the safety physiological characteristics of retrograde non-motor vehicle cyclists were studied. The non-motor vehicle retrograde ratio of three road sections in Xi'an was obtained by high-precision video camera, and the speed and heart rate of cyclists were monitored by using exercise bracelet and mobile phone. Time domain analysis method was used to analyze HRV variability of cyclists during retrograde and normal cycling, and suggestions for improving control measures and optimizing traffic facilities were put forward to guide cyclists to ride healthily and safely. The results showed that the number of electric bikes retrograde was large, but the rate of bicycle retrograde was high, the driving speed and HRV of cyclists decreased, the heart rate increased, which resulted in the increase of sympathetic tension, which was not conducive to the health and traffic safety of cyclists.
