Extending the Modified Voltage Potential algorithm for use in converging traffic flows

The maximum workload for air traffic control officers is a key constraint on the capacity of the airspace system. In the free flight concept air traffic control is removed and aircraft themselves take over its responsibilities. The Modified Voltage Potential (MVP) algorithm is an implementation of this concept. However, its use in the presence...

A Decentralized Recovery Method for Air Traffic Conflicts

In an effort to increase airspace capacity, new methods for the decentralization of air traffic control have been a topic for research since the early nineties. The Modified Voltage Potential is a method to provide decentralized conflict detection and resolution. Through this method, aircraft can fly direct routes while resolving conflicts in a...

Structuring airspace into lateral zones for conflict prevention

In an effort to accommodate the increasing air traffic demand, research is conducted to increase future airspace capacity. In addition to the growing demand, new forms of air transport are entering the market. Although a distributed control strategy seems unavoidable to cope with the introduction of Unmanned Aerial Vehicles and Personal Air...

Multi-aircraft Conflict Resolution using Velocity Obstacles

Currently, Air Traffic Control is responsible for the separation of air traffic in our limited airspace. To facilitate the continuing growth of air traffic, an ambitious plan is to give the responsibility of the separation task to the pilots of the aircraft. The behavior of existing conflict resolution methods within this decentralized approach...

How Do Layered Airspace Design Parameters Affect Airspace Capacity and Safety?

In many ATM studies experiments are performed to determine the capacity. This paper looks at the effect of airspace design on the capacity. Using an algebraic approach a relation is derived between the design parameters of a layered airspace design and the capacity of the airspace. The validity of the assumptions which are used in this...

Aircraft Separation Assurance Using Implicit Maneuver Coordination: Issues and Potential Solutions

In earlier research projects, the depiction of airspace in which a loss of separation is predicted to occur has been explored as a means to increase conflict awareness. The computation of the conflict space is based on the current state of traffic and ownship. If the traffic maneuvers, the location and extent of the conflict space will change...
