    Abstract
  • Aiming at the various, heterogeneous, dynamic characteristics of the synthesized evaluation data for road traffic safety in the integration project of traffic information, an evaluation model of dynamic traffic safety for road section was proposed based on information fusion.The influence factors, such as people, vehicle, highway and environment, on traffic safety were analyzed.The sizes and frequencies of the data sets used in the evaluation model were determined.Factor data correlated with traffic safety were automatically fetched from business database.The evaluation matrix of each factor was generated based on the classifying rules.The safety evaluation was made based on the maximum subordination value calculated by fuzzy comprehensive evaluation formula.The safety evaluation result of Yangling Road Section on Xi'an-Baoji Highway shows that the calculated maximum subordination value is 0.265, which indicates the safety state of the section is safer.Moreover, the factors, such as overspeed, overload, tyre burst and rainy weather, have lower evaluation values.The results are consistent with the statistical data of traffic accidents in the road section.
