Modern unmanned aerial vehicles (UAVs) rely on constant periodic sensor measurements to help avoid obstacles, deal with system disturbances and correct uncertainties. However, constant checking is time and energy consuming and is often not necessary especially in situations in which the UAV can safely fly using open loop control without entering unsafe states. Thus, in this paper we focus on two main...
The main purpose to push the development towards autonomous maritime operations in shipping and offshore installations, is to increase the performance of maritime activities; by social benefits for staff or other related personal groups; by economic benefits when the ability to increase the cargo or effectuate better space allocation; by environmental benefits that's allow the ship operations to be...
Maritime patrol and environmental monitoring tasks, and so on, had attracted the attention of the maritime authorities by USV which instead of some traditional vessels by men control. According to the requirements of the development of the USV and its experimental inconvenience, setting up model ship experiment platform in the service of USV experiments demand, making model ship as its carrier, and...
Modeling and anomalous early-warning of vehicle attitude is an important element of proactive safety management of transport vehicle. However, there are great many uncertain factors for a running vehicle, which causes the anomalous early-warning unable to be realized efficiently. In view of this problem, a driving cycle self-learning system is set up upon the analysis of the vehicle running traits...
To increase competitiveness, reduce environmental impact, improve accessibility and enhance safety and preparedness in the Baltic region, the EU launched MONALISA project which is an e-Navigation solution to achieve intelligent sea route in the Baltic Sea. At first, this paper introduces the MONALISA project. Then it summarizes innovative idea and technology in MONALISA. In the end, based on the present...
Predictive route data are focused by many vehicle manufacturers. The possible information at this juncture is essential to evaluate complex scenarios in urban areas and allow - in combination with active safety systems - reduced probability of crash situations. The presentation illustrates the need of route data, evaluates possible application scenarios and describes technical risks shown by an example...
A Collision Avoidance for Airport Traffic (CAAT) concept for the airport Terminal Maneuvering Area (TMA) was evaluated in a simulation study at the National Aeronautics and Space Administration (NASA) Langley Research Center. CAAT is being designed to enhance surface situation awareness and provide cockpit alerts of potential conflicts during runway, taxi, and low altitude air-to-air operations. The...
This work proposes the development of a control system for an autonomous underwater vehicle dedicated to the observation of the oceans. The vehicle, a hybrid between Autonomous Underwater Vehicles (AUVs) and Autonomous Surface Vehicles (ASV), moves on the surface of the sea and makes vertical immersions to obtain profiles of a water column, according to a pre-established plan. The displacement of...
This paper describes a AIS-based model to assist the design of Ships' routeing system which provide useful insights about complex maritime transportation routes. The AIS analysis model mainly focuses on the transit traffic in the Channel. The AIS provides a method to analyze the vessel traffic density, meeting times and speed conditions in the Channels. An architecture of traffic stress model and...
In this paper, there are presented and discussed the issues regarding the perfection of the information services of the maritime navigation. Although the today developmentpsilas level of information and communications technology (ICT) allow to solve almost every hardware and software issue of information systems, nevertheless there exist very many issues of the maritime navigation information services...
Traffic congestion on major roadways costs our nation billions of dollars in lost earnings, wasted fuel consumption, injury and loss of human life. Providing motorists with real time roadway conditions is essential to mitigating traffic congestion. We propose a novel real-time messaging system that can be used to communicate imminent traffic conditions to motorists. Having such information can allow...
