Analysis and research on the influencing factor of the road transportation network vulnerability based on the interpretative structural model

With the development of science and technology, the process of urbanization has also been accelerated; the problem of road safety has been becoming more and more serious, which made it imperative to solve the problem of road transportation. This paper discusses the related influencing factors of road transportation network vulnerability, analyzes the relationship between various factors, and establishes the model for analyzing vulnerability factors of road transportation network based on the interpretive structural model (ISM). According to the results of the classified model of ISM, this paper analyzes the most direct and fundamental factor leading to road transportation network vulnerability and provides some opinions and suggestions to reduce it.
