Driver's Typical Physiology And Psychology Indexes Regulation And Driving Behavior On Rural Road Under Complicated Condition

Due to problems of the rural road of our country of low technological level,complicated road alignment,poor range of visibility,motor vehicles and non-motorized vehicle mixed seriously.The drivers' perceptions to the external environment are seriously affected.The psychological and physiological state of the drivers changes as well.The drivers' operating abilities are affected and the features are reflected in driving behavior ultimately.Based on the analysis of the driving behavior characteristics of rural road drivers at home and abroad,according to the actual situation of our country,iView X eye tracker,KF2 dynamic multi-parameter physiological detector,steering wheel steering force and angle tester are selected.Visual characteristics,heart rate,other psychological and physiological indexes and driving speed,steering wheel angle are discussed in the poor range of visibility section,grade crossing section and passing through village section.Through the combination of qualitative and quantitative analysis,the influence of complex condition of rural road on driver's psychology and physiology is studied.Furthermore,the driving behavior characteristics in complex sections of rural road are analyzed.Three kind conditions are studied under complex conditions.They are on the typical road sections with poor range of visibility section(R?150m,150m<R<400m,400m?R<600m),the grade crossing section and the passing through village section(entrance,passing region,exit).The test datas are collected in real time before and after the implementation of the national "highway safety life protection project" on the same section.The mathematical models and analysis methods that the Gauss fitting,the least square method and the BP neural network are carried out in this study.In the same section after the change of environment,the characteristics of regular pursuit eye movement and visual features such as short fixation and predictive effect of accessory central fossa are obvious.It indicates that the driver's perception to environment is improved.The small steering wheel angle and other operation behavior reflect that the driver strengthen the risk management ability.At the same time,the behavior of risk compensation is reflected.The influence of environmental conditions on drivers' physiological and psychological characteristics and driving behavior is further explored.Indicators of psychological and physiological and operation behavior are used in this paper.Different mathematical modeling methods are adopted.Driver's typical psychological and physiological regulation and driving behavior on rural road under complicated condition are studied.The deep mechanism of the rural road traffic accident cause is improved.A scientific basis of rural road design,operation and maintenance is provided for the future.
