摘要：AbstractAs an important content of freeway safety management, the freeway infrastructure safety and emergency management system can bring great social effect. In this article, a comprehensive freeway infrastructure safety and emergency management system was built by following steps: firstly, research significance, research status and the paper framework were illustrated. Secondly, in allusion to five kinds of transportation infrastructure: pavement, bridge, tunnel, side slope and ancillary facility, the existing infrastructure testing indexes were summarized, and the relations between traffic safety and these testing indexes were quantified. Thirdly, according to the different characteristic of five kinds of infrastructures, comprehensive safety evaluation models were proposed in order to evaluate the safety of freeway infrastructure. Fourthly, the system of emergency management and emergency plans were expounded. Finally, the system software was developed on the base of research about system framework, database system and Web GIS technology. This system has strong practicability, which can compensate for the deficiencies of the infrastructure detection in the past and provide a new informationalized management platform for freeway management.
