The paper discusses the vertical collision risk estimation methodology and an assessment of the collision risk against a target level of safety. This paper addresses the speed regulation problem in air traffic management. The analysis indicates the technical feasibility of a reduced vertical separation minima in the North Atlantic Region. However, for current operations and technical performance within European continental airspace, the risk estimation indicates that a 1000 ft minima is not technically feasible.

long-range air traffic systems such as trans-ocean traffic overlap spatially. When we consider the relative motion, we can assume that one aircraft is moving and the other. stays at the origin3.

long-range air traffic systems such as trans-ocean traffic. The Reich CRM assumes the time-independent position errors. In addition, aircraft are assumed to fly straight. The Reich CRM gives the ‘total risk’ estimation. The Reich CRM has been applied to many problems. The risk of collision is the product of the proximity probability with the collision risk of proximate pairs. The assumption that aircraft flies straight is not so restrictive when we consider separation minima and route spacing in oceanic airspaces and en-route airspaces.

Longitudinal Collision Risk for ATC Track Systems: A Hazardous Event Model. The algorithm also enables interval estimation of statistics such as lateral overlap probabilities, which is a key parameter of the collision risk model of route spacing. It can be used for long-term monitoring of lateral deviation of aircraft. We also applied the algorithm to the data of lateral deviations observed in Japanese oceanic airspace.

Nay is the risk of collision between the two planes on the parallel route of the same height; β is the frequency of the. average hourly flight of the military airplanes in the military airspace training airspac; 2E (S) is the number of civil airplanes in.

Collision risk estimation in airspace and mathematical modeling of mid-air collisions have been carried out for .

Collision risk estimation in airspace and mathematical modeling of mid-air collisions have been carried out for over more than 40 years. B. L. Marks developed the principles in which a collision risk model could be developed in the early 1960s. However, this model does not cover adequately situations where ground controllers monitor the air traffic through radar surveillance and provide tactical instructions to the aircraft crews.

The steady increase in air traffic imposes a need for enhanced airport .

The steady increase in air traffic imposes a need for enhanced airport capacity. An increase in runway capacity may be achieved by using existing parallel runways more effectively or by building additional parallel runways. An important factor for both is the reduction of the minimum required distance between parallel runways used for independent parallel approaches [14, 17. he minimum required runway spacing for independent parallel approaches has already been reduced several times, thereby trying to maintain the same required level of safety. This enables the identification of hazardous situations, and the derivation of collision risk reducing measures.

In transportation infrastructure, a bidirectional traffic system divides travelers into two streams of traffic that flow in opposite directions. In the design and construction of tunnels, bidirectional traffic can markedly affect ventilation considerations. Microscopic traffic flow models have been proposed for bidirectional automobile, pedestrian, and railway traffic.
