避险车道设置的必要性研究

避险车道设置的必要性一直是国内外学界关注的重点,但是目前却没有成型的理论推出。引进了加拿大和约旦科学家的理论,并且做了相应的改进,提出了新的三个列表:刹车毂温度列表,车速列表,建设条件列表。在三个列表的基础上,加入了权函数的概念。在权函数的设置中,我们充分考虑了三个因素的权重,从而得到了更精确的评价设置必要性。最后,我们在青海湖附近的一个长下坡路段应用了这一理论,得到了比较满意的结果。

Research on Necessity of Risk-Avoiding Setting up for Lane

Necessity of risk-avoiding setting up for lane all along is an attentive emphasis of academic circles at home and abroad,however at present there's no still a typed theory.The paper has imported theories of scientists of Canada and Jordan and accomplished appropriate improvement,puts forward three new lists-list for hub braking temp;list for vehicle speed;list for building conditions.On the basis of three lists the conception of weight function has been added.In setting up of weight function we fully take the weights of three factors into account,thereby we further define necessity for the estimating setting up.Finally,we have applied this theory at a long downslope stretch in the neighborhood of Qinghai Lake and obtained a rather satisfied results.
