Plane Curve Radius Of North Forestry Station Research Based On Driver's Psychological Reaction

The highway of forestry is the artery of the forestry transportation; it is the material foundation bearing forestry production and the management. Generally, during the forestry building and developing, the highway investment must be cost 40%-60% of the total investment, even as high as 70%. It can be seen, the forest road plans is reasonable or not, witch would be affect the economic effect of forestry developing and constructing directly, and it have the important meaning to improve backwardness and to promote the economic growth of forestry. It will have the enormous influence to build the forestry road in forest resources protection, cultivation, using and sustainable development.The Northeast forestry region is the biggest national forestry area of China. It has the very important status in the forestry developing process. At present, The Northeast forest region is being at good level in the resources condition, the economic development, and the ecological environment. Although the forest region developing would be facing some difficulties, it has very important development opportunity. Based on the above reasons, this article will attempt to research the linear of the Northeast forest road, with a new thought, a new method and from other angle, making some contributions to improve tractor efficiency and economic development of the Northeast forest.With this thought, this article will use some theories of human psychophysiology and method and the instrumentation equipment, through the massive driving test, to try to discover some intrinsic relations and rules between the Northeast forest road plane curve linear and the psychological when driver was driving.Human psychological and physiological changes are instant and dynamic. So the physiological signal which it displays often has the complex fluctuation phenomenon. To discover the physiological information relating to the path linear from the driver driving test, this article studies various physiological signal using the spectrum analysis theory and method of the heart rate signal processing technology when the driver driving. For example, in heart rate spectrum of driver driving, can known the most outstanding fluctuation range of the heart rare being affected by road linear, to determine the degree being influence of the driver psychology by forestry road linear.This paper applying regression analysis method, with the massive running test, seeks for each kind of relations and the model between the path plane curve linear and psychological and physiology change when the driver driving. The concrete test result includes:(1) When tractor idling, compute regression model of the drivers'average heart rate, plane curve radius and vehicles running rate;(2) When tractor heavy load, compute regression model of the drivers'average heart rate, plane curve radius and vehicles running rate;(3) Relations between the cross-wind force coefficient and the driver heart rate change;(4) The model is verified and fitted using the concrete experimental road section.
