In order to study road safety as well as the relationship between traffic volume and traffic safety, we introduce matter-element model to build safety evaluation system. In this model, we can get quantitative values of the degree how much it belongs to the certain safety level, including six security indexes such as traffic volume, traffic density and traffic-flow speed, as well as four different security levels. By combining two traffic conditions of the same section, we change the initial parameters of the traffic model to get security level grades of the two conditions. The results showed that with the increase in traffic volume, road safety decreases. However, when the traffic volume increases further, the road safety increases instead.
