The highway infrastructure traffic safety performance evaluation is unstable and unreliable based on the traffic accident number or rate directly as well as other non-accident method. The principle of traffic accident spatial distribution along a highway and correlation between highway traffic safety performance and accidents positions for a period of time were researched. An accident aggregation indicator (AAI) was established based on the principle. In order to validate its availability, AAI was applied to evaluate infrastructure traffic safety performance of 6 region highway networks in Heilongjiang Province, China by using traffic accident data occurring on them in the period 3 years. The remarkable difference of AAI was found on 6 region highway networks, which proved the feasibility of the evaluation method based on AAI.
