The Study Of Driver’s Heart Rate Variable Rule On Mountain Highway

The numbers of people that were killed in traffic accidents in China compared to anothercountry are largest in recent years. The traffic accidents have seriously inflected the life ofpeople and the social harmony. Obviously the traffic accidents have become a public healthproblem. The road traffic containing people, vehicle, road, environment is a dynamicman-machine system. The research demonstrated that the driver play significant role in thetraffic system and account for maximum ratio in all the accident reason.According to statistic data of Chinese traffic accidents, in mountain roads which is two-laneroads, the numbers of traffic accidents are65.5%of all traffic accidents and the numbers ofdeath are78.8%of them. Furthermore, the serious traffic accidents almost were occurred on themountain roads. In the thesis, according to indoor simulation and vehicle test of outdoor, thepsychological and physiological inflection and difference of driver that drive the vehicle on thebend roads and ramp were analyzed in growth rate of hearth rate belonged to psychological andphysiological indicators. In the thesis the research contained some facet:Firstly,when the drivers operated vehicle, they constantly received and dealt with theinformation of roads and then made the decisions. In the mountain roads that the road line shapeis more complex, the information which infects drivers making decision is very sophisticated. Inorder to assure the driving safe, they need timely and accurately handle the information.Furthermore processing the information will lead to the mental state and the psychological andphysiological indicators of drivers making change. The fluctuation of the psychological andphysiological indicators can express the change. In the thesis, the psychological andphysiological indicators system of driver was built by analyzed the application situation ofHuman biological signals in traffic area and selected the representative indicators.Secondly, in this thesis indoor driving simulator which simulates the vehicle test was builtand data collection platform which collects test date of real road was completed. The collectionof the psychological and physiological indicators of driver operating the vehicle was realizedaccording to heart rate fluctuation situation of driver driving the vehicle in the mountain roadswas simulated and analyzed by indoor simulator. Moreover, the heart rates fluctuation ofdifferent ages and different years which drivers have driven also were analyzed; The heart ratefluctuation of driver driving the vehicle in mountain roads was analyzed by real-roads test data collection of mountain roads of Jingyue lake. At the same time, the modeling growth rate ofdriver’s heart rate have been built, and obtained the corresponding regression model.Finally, the difference among drivers and the change law of physiological inflection wereanalyzed in the situation containing indoor and outdoor and the law of driver physiologicalinflection on the same road was contrasted. Then the difference of driver psychological andphysiological inflection can be required. It established the foundation that research the changerelation of psychological and physiological indicators driver operating the vehicle in indoordriving simulation and outdoor real-vehicle roads test...
