The invention provides a method and a system for acquiring the cargo transport lane traffic capacity of a passenger and cargo separating expressway. The method is characterized by comprising the steps of acquiring traffic information data of a section of an expressway cargo transport lane; calculating the axle number of each vehicle in the traffic information data, and selecting a type of vehicles with the axle number occupying the highest proportion as a standard vehicle; clustering all of the vehicles in the traffic information data according to a power-to-weight ratio and overall dimensions, and classifying the vehicles in the traffic information data into M categories according to vehicle types on the basis of a clustering result, wherein the power-to-weight ratio and the overall dimensions of the standard vehicle fall into a certain category of the M categories; acquiring an equivalent convert coefficient of each vehicle type relative to the standard vehicle at a non-car-following state and a car-following state, wherein the equivalent covert coefficient of the vehicle type to which the standard vehicle belongs relative to the standard vehicle is 1; and acquiring the traffic capacity of the section of the expressway cargo transport lane at the non-car-following state and the car-following state under conditions of any vehicle type mixing ratio by being combined with a traffic capacity calculation model according to the equivalent covert coefficients.
