【摘要】：我国是一个汽车大国,汽车的保有量在逐年不断增长,与此同时道路交通事故也在频繁发生。据中华人民共和国道路交通事故事故统计年报数据显示,在所有道路交通事故中,山区公路的重特大交通事故的发生率占了整个公路的10%以上。驾驶负荷分为体力负荷和精神负荷,汽车内部和外部的环境以及驾驶员的身体状况都会影响驾驶负荷的产生,驾驶负荷的增加会促使驾驶员产生不安全的驾驶行为,从而导致交通事故的发生。开展山区公路驾驶负荷的研究有助于了解山区公路对驾驶员工作负荷的影响,为优化山区公路设计,降低山区公路交通事故发生率提供理论支撑,对驾驶员行车安全具有教育意义。基于对前人研究成果及相关理论的总结,针对我国山区公路的特点,本文以三条山区双车道公路为研究对象,对在山区复杂公路不同行车条件下的驾驶负荷进行了试验研究。本文主要分析了直道超车过程驾驶员驾驶负荷的变化、直道会车和弯道会车过程驾驶员驾驶负荷的变化、弯道行驾驶员驾驶负荷的变化及一些特殊行车避让情况下驾驶员驾驶负荷的变化。通过试验数据分析,结果表明:在直道超车、直道及弯道会车、弯道行车及特殊行车避让五种行车条件下,驾驶员的驾驶负荷都会出现增加,其中在特殊行车避让条件下如突遇行人横穿道路时驾驶负荷增加最多,直道超车和弯道会车时驾驶负荷增加较多,直道会车和弯道行车时驾驶负荷增加较少;驾驶员超越小型车辆时承受的驾驶负荷比超越大型车辆时的低;超车过程方向盘转角的增加和转速的变化都会导致驾驶员体力负荷的增加,方向盘转速越快,驾驶负荷越高;超车过程驾驶负荷的明显增加是在超车即将结束时;弯道行车会导致驾驶员驾驶负荷的增加,使得驾驶员的紧张度上升,驾驶负荷随弯道半径的增大呈现减小的趋势,弯道行车时方向盘转角、转速都会导致驾驶员驾驶负荷的增加,方向盘转速越快,驾驶员承受的驾驶负荷越大,但驾驶负荷并不随弯道转角的增加持续增加;在山区公路上行车时,对于不熟悉道路环境、驾驶经验少的驾驶员而言,驾驶负荷相比其他驾驶员会高出很多。
[Abstract]:Our country is a big country of automobile, the quantity of automobile is increasing year by year, at the same time, the road traffic accident also occurs frequently. According to the annual statistics of road traffic accidents of the people's Republic of China, among all road traffic accidents, the incidence of serious and serious traffic accidents on mountain roads accounts for more than 10% of the total road traffic accidents. Driving load is divided into physical load and mental load. The internal and external environment of the vehicle and the driver's physical condition will affect the generation of driving load. The increase of driving load will promote the driver to produce unsafe driving behavior. As a result, traffic accidents occur. The research on driving load of mountain road is helpful to understand the influence of mountain road on driver's workload, to optimize the design of mountain road and to reduce the incidence of road traffic accident in mountain area. It has educational significance to driver's driving safety. Based on the summarization of previous research results and related theories, according to the characteristics of mountain highways in China, this paper takes three mountain two-lane highways as the research object, carries on the experimental research to the driving load under the different driving conditions of the mountain complex highway. This paper mainly analyzes the change of driver's driving load in the process of straight overtaking, the change of driver's driving load in the course of straight passing and the changing of driver's driving load in bends. The change of driver's driving load and the change of driver's driving load under some special conditions. Through the analysis of test data, the results show that under five driving conditions of straight overtaking, straight and bend meeting, curve driving and special driving avoiding, the driver's driving load will increase. Under the special condition of avoiding traffic, the driving load increases the most when the pedestrian is crossing the road suddenly, the driving load increases more when the straight road overtakes and the curve meets the vehicle, and the driving load increases less when the straight road meets the traffic and the curve traffic; The driver's driving load when overtaking small vehicles is lower than that of large vehicles, and the increase of steering wheel angle and the change of rotational speed will lead to the increase of driver's physical load, the faster the speed of steering wheel is, the higher the driving load will be. The obvious increase in driving load during overtaking is at the end of overtaking; Curve driving will lead to the increase of driver's driving load, and the driver's tension will increase, and the driving load will decrease with the increase of the curve radius. The faster the rotation speed of the steering wheel, the greater the driving load the driver bears, but the driving load does not increase continuously with the increase of the corner angle. When driving on a mountain road, drivers who are not familiar with the road environment and have less driving experience will have a much higher driving load than other drivers.
