The invention discloses a road risk early warning controller optimization layout method and system in an intelligent network connection environment, and the method comprises the steps: dividing a road network into n cells, and building a mixed traffic flow model containing the n cells; obtaining the total number of vehicles in each road section and the number of automatic driving vehicles, and calculating the mixing rate of the automatic driving vehicles; calculating a system matrix set A under different mixing rates of the automatic driving vehicles based on the mixed traffic flow model and the mixing rates of the automatic driving vehicles; designing an input matrix Bi based on the mixed traffic flow model; calculating whether the value of Rank (Am, Bi) is n or not by utilizing a system controllability rank criterion; if yes, the input matrix Bi is reserved; screening the input matrixes meeting all mixing rates, and selecting the input matrix with the optimal arrangement position and the minimum number as a control matrix; and based on the control matrix, the controller is arranged. According to the invention, safe and efficient operation of a road network system can be ensured in a complex mixed traffic flow scene.
