    Abstract
  • In order to effectively confirm the safe separation of parallel routes and evaluate collision risk, lateral collision influence factors were analyzed, Reich model and probability theory were introduced, and a computation model of lateral collision rate on parallel routes was established based on VOR navigation in continental areas. The Reich model was improved, a computation formula of lateral collision rate was deduced according to column collision slab instead of cuboid collision slab, and a computation model of lateral overlapping rate between two aircrafts was given according to event probability operation principle. Computation result shows that the computation value of lateral collision rate on gave parallel routes is less than normal value, the flight environment with gave separations is safe, which accords with real condition, so the model is feasible.
