Research of Longitudinal Safety Separation Based on Nagel-Schreckenberg Traffic Flow Model

The relation of traffic flow elements and safe separation is studied in this paper. Under the current separation standard, the reaction times of pilot and the probability of random deceleration were considered, based on Nagel-Schreckenberg traffic flow model, a flight Nagel-Schreckenberg traffic flow model was built according to the movement of the planes on the route. By computing an example the result can show the relation of the probability of random deceleration and the key element of air traffic flow. Furthermore, the optimal longitudinal safety separation of specific airplane is obtained. Compared with the actual air traffic flow, the model is feasible. (C) 2012 Published by Elsevier B.V.
