The invention provides a method and a system for acquiring traffic capacity of a main-auxiliary separation type multi-lane highway. According to the method and the system, all influence factors influencing the traffic capacity of the main-auxiliary separation type multi-lane highway are fully taken into consideration, and six correction coefficients including a change lane correction coefficient, a heavy duty vehicle mix proportion correction coefficient, a main outer lane correction coefficient, an auxiliary outer lane correction coefficient, a main inner lane correction coefficient and an auxiliary inner lane correction coefficient are determined; meanwhile, difference of traffic information data of sections of the highway is fully taken into consideration, and a simulation road network model of each section of the highway is acquired and can really simulate actual traffic conditions; by means of each simulation road network model and according to the single variable control principle, the traffic capacity under various conditions is solved, and then the coefficients are obtained; finally, in combination of the correction coefficients with a traffic capacity calculation model, the traffic capacity of each section of highway under the condition of any heavy duty vehicle mix proportion is obtained.
