In order to lower the rate of roadside accident and help engineers to make an informed decision or take the most effective measures in highway roadside safety improvement program, this article discusses how to make a reasonable evaluation of the roadside safety and how to set the safety facilities for the different roadside dangerous situation. The author put forward a concept of roadside danger and a roadside danger degree evaluation method based on the gray cluster theory. More than ten variables are adopted in the evaluation model. This method can quantify roadside safety performance in terms of the level of roadside danger degree which can be divided into I, II, III and IV four levels. The higher the level is, the worse the roadside safety performance is. And then with some of the cases and a brief analysis, the suitable proposal of the types of safety facilities according to the different level of roadside dangerous degree is provided. An application of the method provided here demonstrates that it can perspicuously and accurately reflect the influences of roadside factors on traffic safety in a complicated system.
