Method for analyzing section traffic capacity of free flow toll road under influence of construction area

The embodiment of the invention discloses a method for analyzing the section traffic capacity of a free flow toll road under the influence of a construction area, and relates to the technical field of intelligent traffic, and the method comprises the steps: constructing a section traffic feature data set of the free flow toll road under the influence of the construction area; calculating a free flow toll road section traffic capacity reduction coefficient; calculating the section traffic capacity reduction coefficient of upstream and downstream roads in the construction area; determining upstream and downstream road vehicle lane changing positions of the construction area; determining the reference traffic capacity of the free flow toll road under the influence of the construction area; and calculating the section traffic capacity of the free flow toll road under the influence of the construction area. According to the method, the influence of the construction area on the free flow toll road traffic capacity
