TL;DR: In this article, the authors apply Buckingham's pi theorem to the problem of building a scaled car whose longitudinal and power-train dynamics are similar to those of a full-size high-mobility multipurpose wheeled vehicle.
Abstract: This paper applies Buckingham's pi theorem to the problem of building a scaled car whose longitudinal and power-train dynamics are similar to those of a full-size high-mobility multipurpose wheeled vehicle (HMMWV). The scaled vehicle uses hardware-in-the-loop (HIL) simulation to capture some of the scaled HMMWV dynamics physically, and simulates the remaining dynamics onboard in real time. This is performed with the ultimate goal of testing cooperative collision avoidance algorithms on a testbed comprising a number of these scaled vehicles. Both simulation and experimental results demonstrate the validity of this HIL-based scaling approach.

TL;DR: Case reconstructions and modeling indicate that most rear-end crashes are due to driver inatt attention, and that this inattention can in theory be addressed successfully by the HD countermeasure concept and available radar technologies.
Abstract: This report describes an analysis of the application of Intelligent Vehicle Highway System (IVHS) technology to the reduction of rear-end crashes. The principal countermeasure concept examined is a headway detection (HD) system that would detect stopped or slower-moving vehicles in a vehicle's travel path. The report is organized to correspond to the major steps of the project methodology: (1) Quantify baseline target crash problem size and describe target crash characteristics; (2) Describe, analyze, and model target crash scenarios to permit understanding of principal crash causes, time and motion sequences, and potential interventions; (3) Assess countermeasure technology and mechanisms of action to identify candidate solutions; (4) Assess relevant human factors and other (e.g., environmental, vehicle) factors affecting crash scenario and potential countermeasure effectiveness; (5) Model countermeasure action to predict effectiveness and identify critical countermeasure functional requirements; and (6) Identify specific priority technological, human factors, and other R&D issues to be resolved. Case reconstructions and modeling indicate that most rear-end crashes are due to driver inattention, and that this inattention can in theory be addressed successfully by the HD countermeasure concept and available radar technologies.

TL;DR: In this article, a collision avoidance system in a host vehicle that employs combined automatic braking and steering is presented, which is based on the speed of the host vehicle, the acceleration of the vehicle and the coefficient of friction of the roadway.
Abstract: A collision avoidance system in a host vehicle that employs combined automatic braking and steering. The collision avoidance system defines thresholds that identify a time to collision with a target vehicle by the host vehicle that are based on the speed of the host vehicle, the acceleration of the host vehicle, the speed of the target vehicle, the acceleration of the target vehicle, the distance to the target vehicle from the host vehicle and a coefficient of friction of the roadway. The collision avoidance system provides full automatic collision avoidance braking if the time to collision is less than one threshold and the lane adjacent to the host vehicle is not clear. The collision avoidance system provides both automatic steering and braking of the host vehicle if the time to collision is less than another threshold and the lane adjacent to the host vehicle is clear.

TL;DR: In this article, the authors investigated the possibility of reducing the number of accidents involving pedestrians or other vulnerable road users (VRUs), like cyclists and motorcyclists, by providing the control systems of the vehicles of the platoon with some collision detection and avoidance capabilities.

TL;DR: In this article, the feasibility of unmanned, autonomous merchant vessels is investigated by the EU project MUNIN (Maritime Unmanned Navigation through Intelligence in Networks), where ships will be manned during passage to and from port and unmanned during ocean-passage.
Abstract: The feasibility of unmanned, autonomous merchant vessels is investigated by the EU project MUNIN (Maritime Unmanned Navigation through Intelligence in Networks). The ships will be manned during passage to and from port and unmanned during ocean-passage. When unmanned, the ships will be controlled by an automatic system informed by onboard sensors allowing the ship to make standard collision avoidance manoeuvres according to international regulation. The ship will be continuously monitored by a remote shore centre able to take remote control should the automatic systems falter. For the humans in the shore control centre the usual problems of automations remains as well as a pronounced problem of keeping up adequate situation awareness through remote sensing.
