Grey clustering evaluation for crosswalk traffic safety condition

Base on MATLAB software, a grey clustering analysis method was applied to evaluate crosswalk traffic safety condition in this paper. Crosswalk traffic safety condition was divided into four grey grades, such as excellent (A-level), good (B-level), average (C-level) and poor (D-level). According to the grey clustering method, the evaluation matrix, whiten weight functions of every grey grade and comprehensive decision weights were given. Evaluation results suggest that: the theory of grey clustering evaluation for crosswalk traffic safety condition is practicable and reliable, and may be used for other road traffic safety condition evaluation.
