摘要：Three models are established under the multivariate nonlinear regression analysis technology, and on the base of the existing and survey data, which are the double-lane road alignment safety evaluation model, the psychological reaction of driver safety evaluation model and the driving safety comprehensive evaluation model. Then, a quantitative evaluation of the experimental section is made by the comprehensive established evaluation model, and the security level is gained. Moreover, how to improve the security level of the experimental section is advanced, that is to set the hollow LED variable speed-limit sign. Finally, a comparison of the experimental section�s security level before and after carrying out the hollow LED variable speed-limit sign is made by using the simulation software to verify the effectiveness and feasibility of this measure.
