【摘要】：為研究駕駛員心率與山區(qū)公路縱斷面坡度及車(chē)速間的關(guān)系,隨機(jī)選取26名駕駛員在山區(qū)三級(jí)公路進(jìn)行實(shí)車(chē)試驗(yàn)。利用動(dòng)態(tài)生理儀采集駕駛員行車(chē)時(shí)的心率數(shù)據(jù),GPS采集試驗(yàn)車(chē)輛的實(shí)時(shí)車(chē)速數(shù)據(jù);通過(guò)偏相關(guān)分析,確定出影響駕駛員在山區(qū)公路縱坡路段行車(chē)時(shí)心率變化的主要因素,并建立上坡方向行車(chē)時(shí)駕駛員心率增長(zhǎng)率與坡度及速度的關(guān)系模型。分析結(jié)果表明:上坡方向行車(chē)時(shí),駕駛員的心率增長(zhǎng)率隨坡度增大而增加、隨速度的增加而增大;因此,考慮駕駛員的舒適性和安全性,建議山區(qū)雙車(chē)道三級(jí)公路上坡方向最大安全坡度不宜超過(guò)6.8%。
[Abstract]:In order to study the relationship between the heart rate of drivers and the longitudinal slope and speed of mountain highway. 26 drivers were randomly selected to carry out the actual vehicle test on the third-grade highway in mountain area. The real time speed data of the vehicle were collected by using dynamic physiological instrument to collect the heart rate data while driving and GPS to collect the real time speed data of the vehicle. Through partial correlation analysis, the main factors that affect the heart rate change of drivers driving in mountain highway longitudinal slope section are determined. The relationship model of heart rate growth rate with slope and speed is established. The results show that the increasing rate of heart rate increases with the increase of slope. It increases with the increase of velocity. Therefore, considering the comfort and safety of drivers, it is suggested that the maximum safety slope should not exceed 6.8 in the uphill direction of two-lane third-grade highway in mountainous area.
