Embodiments of the invention provide a system and method for estimating saturation flow of a signal intersection based on vehicle trajectory data. The system may include at least one storage device configured to store instructions and at least one processor configured to execute the instructions to perform operations. The operations may include receiving trajectory data for at least two vehicle movements associated with the intersection via a communication interface. The operations may also include determining a period length of the intersection based on the trajectory data. The operations mayalso include determining a time-distance relationship of the vehicle motion based on the period length. Additionally, the operations may include detecting a traffic wave based on the time-distance relationship. Further, the operations may include determining a saturation flow rate of the intersection based on the traffic flow wave.
