The invention discloses an intersection signal timing and vehicle trajectory collaborative optimization method and device. The method comprises the following steps: acquiring time information and driving information when a vehicle enters a communication range; constructing to obtain an upper layer model and a lower layer model; the optimal signal timing scheme under the current traffic flow is calculated according to the upper layer model, the signal timing scheme is transmitted to the lower layer model, and the lower layer model predicts the time when the vehicle arrives at the intersection and optimizes the driving track of the vehicle according to the optimal signal timing scheme. An optimal vehicle driving track scheme is obtained; and finally, the optimal signal timing scheme is transmitted to a signal lamp system at an intersection for signal timing, and the optimal vehicle driving track scheme is transmitted to each driving vehicle system in a communication range for vehicle track control. According to the method, intersection signal timing and vehicle tracks can be optimized cooperatively, vehicle delay and tail gas emission are reduced at the same time, and the method can be widely applied to the technical field of computers.
