The density of air traffic, particularly in the USA, is now X increasing at such a rate that the overloading of the Air Traffic Control system seems inevitable. Fig. 1 shows the expected increase in the size of the US civil air fleet and its operations over an eleven-year span, from 1966 to 1977.Since January 1st 1968, there have been 58 mid-air ...

Collision Avoidance for Vehicle-Following Systems
IEEE Transactions on Intelligent Transportation Systems, 2007The vehicle-following concept has been widely used in several intelligent-vehicle applications. Adaptive cruise control systems, platooning systems, and systems for stop-and-go traffic employ this concept: The ego vehicle follows a leader vehicle at a certain distance. The vehicle-following concept comes to its limitations when obstacles interfere with

Automatic air collision avoidance system
Proceedings of the 41st SICE Annual Conference. SICE 2002., 2003This paper presents an algorithm for an automatic air collision avoidance system being developed by the US Air Force and its Swedish counter part, Forsvaret Materielverk (FMV). The algorithm uses optimal coordinated escape maneuvers to avoid mid-air collision, while satisfying the imposed system requirements.

Intersection Collision Avoidance System Architecture
2008 5th IEEE Consumer Communications and Networking Conference, 2008In this preliminary paper we propose new intersection collision avoidance architecture. This system allows vehicles to establish secure links with roadside unit installed at the intersection before entering the furthest point where vehicles start to share their current state with the roadside unit.

Collision Avoidance in Bi-Directional AGV Systems
The Journal of the Operational Research Society, 1994Summary: The use of a bi-directional, as opposed to a one-way, transportation system, can increase the operational efficiency of automated guided vehicles in both manufacturing and warehousing environments. However, the full potential will only be realized if the routeing algorithms pay particular attention to the problem of collision avoidance.

Aircraft Collision Avoidance System
2007 IEEE Aerospace Conference, 2007This paper describes a new design concept of airborne equipment of secondary radar systems. The concept allows implementing two principal airborne systems, more exactly Mode S transponder and TCAS, as a multifunctional unit. This concept gives a possibility to make half the number of necessary aircraft antennas as well as to decrease the number of ...

An advanced collision avoidance system
ATZ worldwide, 2005Driver assistance systems have made a significant contribution towards improving vehicle safety. The long-term objective of such developments is to produce a complete collision avoidance system. Within the framework of the Invent project and as part of a collaboration between Volkswagen AG and the Helmut Schmidt University/University of the Federal ...

An Alternative System of Collision Avoidance
Journal of Navigation, 1984Collision statistics indicate that many collisions at sea occur after one or both vessels take action to avoid collision. It is worth considering why this should be so. Is the action taken contrary to the requirements of the Regulations for Preventing Collisions at Sea or are the Rules unsatisfactory in not stating clear and effective requirements?
