Method for determining influence range of construction traffic organization based on cascade effect

The invention relates to a method for determining a construction traffic organization influence range based on a cascade effect, and the method comprises the following steps: forming a research region according to a region where a to-be-constructed road section is located, the to-be-constructed road section is a construction road section, and the other road sections are normal road sections; basic information of each road section in the research area is collected; calculating a first overload traffic volume C3 of the construction road section according to the total lane number D1, the construction lane number D2, the design traffic volume C1 and the peak period traffic volume C2 of the construction road section; when the first overload traffic volume C3 is less than or equal to 0, the construction road section is an influence range; when the first overload traffic volume C3 is larger than 0, the first overload traffic volume C3 is distributed to the normal road sections from near to far with the construction
