16 Sep 1998TL;DR: In this paper, a traffic guidance system for controlling, guiding and optimizing traffic movements, where a sensor is provided for detecting the momentary traffic situation, is characterized having in mind an effective control of traffic movements.
Abstract: A traffic guidance system for controlling, guiding and/or optimizing traffic movements, wherein a sensor is provided for detecting the momentary traffic situation, is characterized having in mind an effective control of traffic movements, even in a heavy traffic volume, in that the sensor comprises a radio receiver, and/or a receiver for optical signals, and/or a receiver for acoustical signals for radio signals, and/or optical signals, and/or acoustical signals emitted by road users.

21 May 2018TL;DR: The proposed MPC COLAV method does not rely on an accurate model of the guidance system to achieve vessel behaviors that are compliant with the COLREGS, but depends on transitional costs in the MPC objective for collision avoidance maneuvers that are being executed by the marine vessel.
Abstract: This paper presents a viable approach for incorporating collision avoidance strategies into existing guidance and control systems on marine vessels. We propose a method that facilitates the use of simulation-based Model Predictive Control (MPC) for collision avoidance (COLAV) on marine vessels. Any COLAV strategy to be applied in real traffic must adhere to the international regulations for preventing collisions at sea (COLREGS). The proposed MPC COLAV method does not rely on an accurate model of the guidance system to achieve vessel behaviors that are compliant with the COLREGS. Rather, it depends on transitional costs in the MPC objective for collision avoidance maneuvers that are being executed by the marine vessel. Hence, it is straightforward to implement the MPC COLAV on different vessels without specific knowledge of the vessel's guidance strategy. Moreover, it offers the possibility to switch between different (possibly application specific) guidance strategies on the same vessel while running the same MPC COLAV algorithm. We present results from full scale experiments that show the viability of our method in different collision avoidance scenarios.

TL;DR: The performance of the Orbiter entry guidance system has been excellent during all of the space shuttle flights as mentioned in this paper, and the entry guidance objectives and control concepts have been summarized and discussed.
Abstract: The performance of the Orbiter entry guidance system has been excellent during all of the space shuttle flights. This paper summarizes the entry guidance objectives and control concepts, reviews the entry guidance preflight predicted results, and presents the significant entry guidance and trajectory flight results from the first three Orbiter flights. Emphasis is on the steady-state characteristics from the first and third missions and on the transitory response characteristics resulting from the major Orbiter aerodynamic test maneuvers on the second flight.
