The invention belongs to the field of information physical system control, and discloses a CPS control strategy for expressway high-flow passing efficiency optimization, which comprises the following steps: S1, determining a system-level objective function by taking communication overhead, calculation overhead and cluster correlation degree required by a road section cluster structure as optimization targets; s2, solving an optimal road section cluster structure of the expressway in a current traffic state; s3, establishing five subsystem-level objective functions, and establishing a multi-objective optimization problem; s4, solving a multi-objective optimization problem to obtain an optimal control decision; s5, judging whether active control measures are started or not and whether a control decision is updated or not; s6, calculating the expected speed of the vehicle; and S7, the main road ICV of the road section travels according to the expected speed, and the ramp ICV travels according to the ramp control signal. According to the strategy provided by the invention, the network connection relationship between the roadside equipment can be dynamically adjusted, targeted information sharing and cooperative control are realized, the communication resource overhead is saved, and the distributed cooperative control of the expressway under the limited constraint of the cyber resources is realized.
