Inland passenger shipping is one of the most convenient means of waterborne travel. However, recent serious accidents with passenger ships in China, have exposed a certain weakness in the country's inland passenger ship safety system. It is thus vital to overview the current conditions of China's inland passenger ship safety system, with regard to the different ship types, employment, management systems,...
To ensure safe ship navigation, true water depths should be deep enough with respect to the corresponding depths on a chart. Therefore, a set of basic quality indices, including an index of the probability of adequate depth, were developed to evaluate the quality of a digital depth model (DDM) with respect to navigational safety. In addition, these methods are proposed for assessing the probability...
Research on the waterway traffic flow modelling has been widely used in the formulation of waterway transportation regulations, navigation risk assessment, vessel traffic monitoring and organization. The fluency of one-way waterway transportation is proposed in this paper. By using the model, a simulation system is constructed on the basis of First Come First Served (FCFS) model. Monte Carlo simulations...
Mobility assistance for wheelchair navigation is typically based on the shared control paradigm. Traditionally, control swaps from user to machine depending either on a trigger mechanism or on a explicit user request. Alternatively, in collaborative control approaches both user and robot contribute to control at the same time. However, in this case it is necessary to decide how much impact the user...
Scientific principles of ground navigation visual aids -lighting systems - design for civil aviation aerodromes are suggested. All grounds based on modern international standards and recommended practice.
The flow increasing of civil aviation requires reducing the separation minima to improve the usability of the airspace, and then we attempt to evaluate the safety of the reduced separation minima so as to ensure the flight safety. This article includes a detailed analysis of the collision risk on the parallel route and intersecting route, and emphasizes on building the united collision risk model...
