Traffic safety is a hot topic. Although traffic safety has improved, overall, for many developing countries, traffic safety fluctuates from year to year. Many studies have explored the issue of traffic safety evaluation from the perspective of the road, but little traffic safety evaluation is from the perspective of the city-cluster region. This paper adopts the fuzzy clustering theory to analyse the traffic safety level in the Beijing-Tianjin-Hebei region. Through calculation and analysis, it can be concluded that the traffic safety level in the city-cluster region of Beijing-Tianjin-Hebei differs among the three. The result shows that the overall traffic safety is improved in city-cluster of region of Beijing-Tianjin-Hebei, they are divided into two categories according to calculations. The traffic safety is relatively stable in Beijing and Hebei, but the traffic safety is more severe in Tianjin. The conclusions can provide a theoretical basis for the integrated traffic safety of Beijing-Tianjin-Hebei.
