VANET Simulation schemes require a combination of mobility and wireless network simulation packages, coupled with custom scripts, visualization tools and various scenarios. The results of simulation studies need to be supported by special tools or scripts to analyze or visualize them easily. Some additional difficulties arise at sharing the results, visually comparing simulation runs across different...
Steering control for vehicle lane keeping has attracted wide attention from both automotive industries and vehicle control researchers. Commonly used linear control models cannot adequately represent the intermitted pulse-like qualities seen in real-world, naturalistic steering measurements. Therefore, an alternative ‘pulse control model’ (PCM) was recently proposed to take account of this property...
Carsharing has emerged as an alternative to vehicle ownership and is a rapidly expanding global market. Particularly through the flexibility of free-floating models, car sharing complements public transport since customers do not need to return cars to specific stations. We present a novel data analytics approach that provides decision support to car sharing operators -- from local start-ups to global...

Eye tracking can reveal an individual's state of mind. In this paper, taking into consideration that cognitive distraction that may be expressed both serially and quantitatively, we designed the Driver's Cognitive Process Model by expressing the relationships between cognitive states, such as perception and memory, from eye tracking which we utilized as an input to the driving action which we considered...
In this paper, we propose a new computational model of driver car-following control with lateral control based on the Queuing Network (QN) cognitive architecture. A driver car-following model within the framework of the QN cognitive architecture is first developed based on the time headway and then integrated with a QN-based driver lateral control model previously validated. The comparison between...
By establishing realistic battle environment in simulation training, to study military action, is an important way of training commander's ability to command decisions and improving our ability to command decision in the future war comprehensive ability. This paper focus on the construction of virtual battle environment, introduces a method of building virtual battle environment based on HLA. Practice...
Present generation AUVs act as mobile sensor platforms, allowing post mission debriefs which require little more than an adequate expression of the collected data, and only basic requirements for mission planning. As the need and capability advances, autonomy will increase in turn, leading to more complex missions, which must be supported by more capable operator interfaces, both for post mission...
This paper presents a novel self-supervised on-line learning method to discover driving behaviors from data acquired with an inertial measurement unit (IMU) and a camera. Both sensors where mounted in a car that was driven by a human through a typical city environment with intersections, pedestrian crossings and traffic lights. The presented system extracts motion segments from the IMU data and relates...
Protection of large and complex urban areas from radiological threats may be improved by employing a network of distributed radiation detectors. Among the many considerations involved in designing such a system are detector type, concept of operations, methods to collect and extract meaningful information from multiple data sources, and cost. We have developed a realistic simulation environment as...
In this paper, we summarize the initial results with regard to the question to what extent driving simulators can be used to serve as cheap and easy realizable environments for simulating on-the-road behavior. The aim of these first studies was to determine whether or not it is possible to replace real driving studies with experiments and furthermore, to identify parameters and/or restrictions for...
In this paper, it is shown that synthetic images can be used to test specific use cases of a lane tracking algorithm which has been developed by Audi AG. This was achieved by setting up a highly configurable and extendable simulation framework ldquovirtual test driverdquo. The main components are a traffic simulation, visualization and a sensor model which supplies ground truth data about the street...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
