Detectors are challenged in providing stable and accurate information of the dynamic origin–destination (O–D) flows for real‐time adaptive traffic signal timing operation. However, the dynamic O–D estimation technique is capable of providing a short‐term turn‐flow data for the signal‐timing adjustment. Meanwhile, the real‐time signal timing variations will affect the dynamic O–D flows in an actual network. Therefore, the dynamic O–D estimation and the real‐time signal control closely interact with each. A combined model is proposed to dynamically calculate the signal adjustment answering the variation of the real‐time O–D flows by minimising the accumulative queues in entering approaches. A case study was conducted to validate the proposed model and algorithms, and the result showed the traffic efficiency of the case study intersection was improved.
