The invention provides a layout method and system for installing a communication device on an existing detector of an expressway, and the method comprises the steps: obtaining the speed information of a microwave detector of the expressway and the speed information of a CAV vehicle, and carrying out the preprocessing of the obtained data; the preprocessed data serve as input, fusion location information serves as output, and a fusion function is established through a long-short term memory neural network; training and testing the information; establishing an optimization model of an existing detector additionally provided with a communication device; the model is solved based on a genetic algorithm, an optimal layout mode is obtained, maximum utilization of existing resources is guaranteed, the function of vehicle communication is achieved by deciding which microwave detectors in an existing road are additionally provided with communication devices, a traditional detector is converted into an intelligent roadside facility, more information on the road is obtained, and the traffic safety is improved. And the estimation precision of the time average speed of the road is optimal. According to the method, a reasonable and effective layout optimization scheme can be obtained, and universality and feasibility are high.
