ABSTRACT
To analyze and validate the mechanism between discovery time and duration time in traffic incidents, 23,268 samples from the Shaan’xi Province in China were collected by the expressway monitoring and control system. First, discovery time and influencing factors were introduced to construct the theoretical model, and then the hypotheses among the variables and intermediary effects were verified based on SPSS. The results show that discovery time and duration time are positively correlated. Discovery time not only directly affects duration time but also can indirectly by three mediating effect paths. Consequently, the discovery time is statistically significant and positively mediates and reduces the duration of expressway traffic incidents. Therefore, the important reference value of the research results lies in that discovery time is the first phase in the entire duration time. Therefore, it is the key factor affecting duration time to improve response efficiency.
