The invention provides an intersection flow direction traffic control index estimation method, device and equipment, and the method comprises the steps: obtaining a lane evaluation index of each lane according to detector data and lane configuration data, the lane evaluation index at least comprising one of the following: a lane flow rate ratio and a lane green light utilization rate; the flow direction flow rate ratio of each flow direction of the intersection is obtained according to the lane evaluation index and the lane configuration data, the flow direction flow rate ratio of each flow direction is equal to the lane flow rate ratio of the reference lane of the flow direction, and the lane green light utilization rate of the reference lane of each flow direction in the related lanes of the flow direction is maximum; and the traffic control indexes are sent to a signal control timing optimization module, and the signal control timing optimization module distributes the green light time of the flow direction of the intersection by using the flow direction flow rate ratio. According to the method, the flow direction flow rate ratio is obtained according to the lane flow rate of the flow direction reference lane, the more accurate flow direction flow rate ratio is obtained, and when the method is used for optimizing the green light time of the flow direction, the traffic smoothness is improved.
