In this paper, we study the macroscopic traffic dynamics and propose models of traffic mean speed and density of each lane under speed drop of connected and autonomous vehicles (CAVs) in three-lane freeway scene in wave propagation perspective. The propagation of macroscopic traffic waves in mixed streams is analyzed to derive functions of macroscopic traffic flow parameters of each lane in different evolution process. Three superposition principles of traffic wave are proposed to analyze compound disturbances in different propagation periods. The experiments are performed in simulation of urban mobility SUMO platform under various CAVs penetration, speed drop of CAV, the proposed model is capable of adequately describing the evolution process of mixed traffic flow after speed drop,
