摘要

This study developed a safety evaluation model of freeway traffic safety facilities based on the grey entropy weight clustering. Firstly, a safety evaluation system of freeway traffic safety facility was proposed including six aspects. Then, whitenization weight function was defined and weights of indexes were determined by entropy theory. The grey entropy clustering coefficient was calculated, and the safety level of freeway traffic safety facility was evaluated afterwards. Finally, a case study of Yun-Luo freeway (a segment of 5.5 km) was conducted to verify the feasibility and effectiveness of the model.
