[Abstract]:In order to study the influence of the change of mainline connectivity in time dimension on the choice of rescue route in expressway construction accident, the factors influencing the division of rescue route management unit are analyzed. The main criteria for controlling project selection and the time series of construction progress are presented. Introducing time parameter, the linear entity of expressway construction project is divided into periodic point element, periodic line element, instant point element and instant line element. The dynamic management unit partition model based on the control of construction progress is established and the road network optimization model is established based on the road resistance function to realize the dynamic management of the emergency rescue network. The application of the research results to the expressway along the Yangtze River in Chongqing shows that when the time parameters are less than 14, 20 months and more than 36 months, the rescue time is reduced by about 626 and 37 min, respectively, and the rescue efficiency is improved by comparing the emergency rescue network before optimization.
