Vehicle-to-vehicle (V2V) communications can complement systems based on host vehicle information and are being actively researched. We suggest a safety service models using vehicle-to-vehicle communication when vehicles move in intersection. The suggested model uses wireless access in vehicular environment (WAVE) proposed by IEEE WG 802.11 and P1609 as the V2V communication protocol. This communication...
In this paper, we propose a communication protocol for an automatic report service to decrease damage from accidents and increase driver safety service for vehicles. The automatic incident report service is operated using V2X communication based on wireless access in vehicular environments (WAVE) to control the incident information from the accident car to the observing car. All observing cars can...
Technologies designed to reduce the car accidents are recently being developed. One of type, vehicle to vehicle communication has proven to be highly effective for safer driving. However, effectiveness of vehicle to namdic devices communiation has been overlooked. In this paper, we designed a communication architecture between WAVE and Android. WAVE is the standard protocol of vehicle communication,...
This paper presents the navigation of an entertainment robotic vehicle that follows the line on the pavement. The robotic vehicle is built with the purpose of carrying two passengers to look around the campus. Instead of using fully autonomous techniques, a semi-autonomous line following task is implemented. A line is detected by a camera from the pavement with two colors and used as the reference...
Many practical engineering applications require the numerical solution for the analysis of the EM field by a moving source and/or a moving body. We have previously proposed the Overset Grid Generation method coupled with FDTD method for the analysis of the EM field with moving boundaries considering Doppler Effect. By overlapping one moving sub-mesh on a static main mesh, each mesh is calculated alternately...
Vehicle to Vehicle(V2V) is an important communication medium for safety and comport of drivers. Accordingly, V2V researches based on IEEE 802.11p standard is being actively investigated in many countries. V2V researches which is fors and againsts per each study from many simulation as well as the vehicle test is being conducted. Among them, we especially need to use NS2 which is simulator similar...
Vehicle Video detection is an important part of intelligent transportation system for its characteristics of effectiveness and accuracy, and it provides important data for the security of urban traffic operation. However, in order to improve the reliability of vehicle detection in the traffic video detection system, in this paper, a pulse-coupled neural network (PCNN) is used for the image segmentation...
This paper introduces the Research Concept Vehicle (RCV), an experimental research and demonstration vehicle developed at KTH Royal Institute of Technology. The vehicle is intended as a platform to implement, validate, and demonstrate research results from different research projects carried out at KTH. In its first generation, the RCV is a pure electric vehicle where each wheel is equipped with an...
This paper reports on the integration and evaluation of a Tritech Micron mechanical scanning sonar into a Slocum underwater glider. The intend is to use the Slocum glider with the scanning sonar, to conduct seafloor and iceberg mapping tasks. The mechanical scanning sonar is installed in the extended, free flooded area of nose of the glider. After the successful integration, initial field trials were...
It is the purpose of this paper to encourage the use of unmanned aerial vehicles (UAVs) for the development of interdisciplinary engineering education projects. The use of UAVs is an excellent tool to gather students from various engineering and science fields. This paper explores the different features that a four-rotor UAV is used for STEM education including the training of undergraduate students...
People pay attention to the relationship between drivers' state before driving and subsequent vehicle operation as drivers' state like insomnia and overwork may contribute to traffic accidents. In this study, we classified drivers' state based on their sleeping hours before each driving session, and then we tried to bring out the effects in vehicle operation data, 20 in total, due to drivers' sleeping...
Association of Radio Industries and Businesses (ARIB) has standardized ARIB STD-T109 for IVC (Inter Vehicle Communications) and RVC (Road to Vehicle Communications) as applications of Intelligent Transport Systems in 700 MHz band. In ARIB STD-T109, IVC and RVC share one channel by employing time division duplex. It is possible to avoid frame collisions between IVC and RVC by this scheme. Moreover,...
As part of the ongoing Responsive AUV Localization and Mapping project (REALM) Memorial University has been developing an autonomous path localization and following system. This Qualitative Navigation System (QNS) localizes an AUV to a predefined path and generates control inputs to maintain the AUV along that path without the need for an absolute position estimate. QNS processes sonar data into the...
The PVC-ROV underwater robot testbed is a low-cost, three vehicle system designed to support research into multi-robot control techniques. Each vehicle is composed of a PVC frame with bilge-pump motors, a central microcontroller, and hobby-class sensing and power components. In addition, each vehicle is tethered to a surface buoy by a 15 meter tether and wirelessly exchanges data with an off-board,...
This article discusses about the application of unmanned vehicles networks in several areas related to power systems. The main topics are related to the planning and mission control tools as well as coordination, communication and data sharing between the associated nodes. Throughout the work, some vehicles developed in the Underwater Systems and Technology Laboratory (LSTS) will also be presented,...
Vehicle flow volume on the motorway in the urban area is successfully used to realize traffic decision-making and guidance. In this research, we introduced some critical components into a vehicle flow detection system. In order to enhance the accuracy and instantaneity of the vehicle counting in quick-change traffic conditions, an adaptive modeling and updating method of background was proposed. In...
Nurturing design skills in students is in the heart of all engineering curricula. While academic courses and capstone activities inject the design process in students, involvement in practical design activities is believed to have higher impact on student preparation for engineering professions. Capitalizing on this fact, this paper aims to study the impact of Shell Echo-Marathon (SEM), an international...
Given the importance to understand the sustainability and environment concepts and how technology can help solving environmental issues, we propose a course and methodology where computer engineering students learn new concepts, discuss problems and solutions, and design technological solutions to minimize the problems of those areas. This paper presents the experience with the design and developing...
Tauxschema is a framework for constructing and validating time-varying XML documents through the use of a temporal schema. This latter ties together a conventional schema (i.e., A standard XML Schema document) and its corresponding logical and physical annotations, which are stored in an annotation document. Conventional schema and logical and physical annotations undergo changes to respond to changes...
With the aging driver increasing, the smarty automatic driving system needs to be proposed. We analyze the smarty automatic driving system to propose a smarty platooning control system based on the automatic driving system for elderly person. Firstly, the small automatic electric vehicle and the control devices are explained. Then we introduce the Wireless communication method in our system. Based...
