The invention discloses a bidirectional signal coordination design method and device for a supersaturated traffic state trunk line. The method comprises the following steps: acquiring geometric parameters, traffic parameters and control parameters of a target road section of the trunk line in the supersaturated traffic state and traffic flow data in a time period to be optimized; taking the trunkline as a modeling object, constructing an optimization model taking maximization of the weighted throughput of the trunk line in two directions as a target, and realizing maximization of the throughput of the trunk line by adjusting the duration of the green light; solving the model to obtain the green light duration of each phase of each intersection of the trunk line; taking each intersection of the trunk line as a modeling object, constructing an optimization model taking minimization of weighted vehicle average delay in two straight going directions of the main line as a target, and realizing minimization of the
