Along with the increase of traffic volumes of airports, runway incursion events are increasing rapidly, which have certain influence on airport safety, so the evaluation of runway incursion hazard is very significant. This paper analyzed the runway incursion events by using the method of dynamic event sequence diagram ESD, describing the runway usage and operating conditions of the airport runway under the regulatory process and studying the influence of dynamic factors on the system and accident development process and its consequences. The research indicates that the occurrence of the scene events can be taken away in time without eliminating the danger source, which can effectively avoid the occurrence of runway incursion, so it can provide some new ideas and directions for preventing runway incursion.
