Study On Influencing Factors Of Grassland Tourism Highway's Grade Division

With the constant improvement of highway mileage and the rapid development of grassland tourism in Inner Mongolia, the service quality of tourism is higher required,so it is the urgent need to build a special tourism highway to preferably serve tourism . Tourism highway is, not only the mean and tool of tourists'spatial transference, but also a part of the grassland, and it should coordinate with the surrounding environment. Therefore, while driving safety is considered, driving comfort and the ecological environment are paid more and more attention to. So far, while dividing grassland highway's grade, driving comfort and the ecological environment haven't been considered as influencing factors, also the relation between the grassland traffic accidents and the driver's psycho-physiological responses has hardly been studied. It is known the drives are the dominant factor in the highway traffic human-machine system who are vulnerable to be influnced by the system environment. During the process of traveling on the grassland highway, the drivers are little affected by the outside information stimulation, and they are easy to relax vigilance because of the tedious grassland landscape and the simple alignment. Hence, research on the grassland highway's grade by analyzing drivers'psychological and physiological responses is very essential to reduce the psychological bueden on drivers and grassland highway traffic accidents, raise the service level and capacity of grassland highway.Through field experiment and laboratory simulations experiments, the difference of conners'psychological and physiological responses on third-grade grassland highway and mountainous highway are analysed. The study verified that tourists' physiological signals has obvious changes while drivering on the grassland highway, so it is significant to consider driving security and comfort as influencing factors of grassland highway's grade.There are some conclusions from field experiment and laboratory simulations experiments.As follow: the drivers'physiological and psychological reflections are significant differences on the grassland highway and the mountainous highway, and when driving on the grassland highway, the drivers'mental load is increasing. Which verified that the toutists' security and comfort should be considered as influencing factor of the grassland tourism highway's grade.In a conclusion,the traffic volumn,the toutists' security and comfort and ecological factors should be considered while the grassland tourism highway's grade is divied.
