The calculation of real-time air traffic flow is a primary research element of air traffic management. A real-time air traffic flow computational algorithm based on surveillance data is proposed in this paper. In this algorithm, airspace is divided into three categories： surface airspace, line airspace and point airspace. And correspond computational algorithms are designed respectively. Moreover, a specific calculating flow is designed in order to avoid double counting of the traffic flow in special locations. With the verification of real flight paths, this algorithm is able to calculate the real-time traffic flow in different airspace unit, and also meet the requirement of actual flight rules and airspace using regulations. Thus, the proposed algorithm has much reference value and is practical, as well as an effective way to calculate real-time air traffic flow.
