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 vehicle average delay by adjusting a phase difference and a phase scheme; and solving the model to obtain the phase difference between the intersection and the upstream intersection thereof and the phase scheme of each intersection. According to the method, the throughput maximization model and the vehicle average delay minimization model are established and solved, and the trunk line traffic capacity and the service level can be effectively improved.
