In urban crossroad areas the traffic flow is commonly not efficient. This results in an unnecessary high traffic density within cities and a resulting environmental pollution by the waste of fuel. To improve this situation, the driver should be enabled to better slow down, to better accelerate, to better decide, to better come in and to better follow within crossroads. This can be achieved by a C2X-based...
Vehicular Ad Hoc Network (VANET) is considered promising for ubiquitous communication on roadways and one-hop broadcast plays a leading basic role in VANET. Thus, there is a strong need of high reliability related to packet transmission and reception especially when VANET is used for life-safety applications. Though IEEE 802.11p has been defined as an international standard for VANET, IEEE 802.11p...
An experimental laboratory setup is presented where students can familiarize, study, set-up, tune and test the propulsion motor drive. Paper gives a brief overview about experimental setup construction and application, as well about the course, where it is used, and laboratory exercise contend. The topics covered by developed laboratory works could be interesting for interdisciplinary studies in different...
The use of battery electric vehicles (BEV) has not seen equal treatment across the US with consumers in non-urban and rural areas reporting themselves as the least likely group to consider purchasing a BEV. Studies show that rural customers are more susceptible to longer daily driving distances, insufficient charging infrastructure, and lower consumer awareness, all of which decrease BEV adoption...
This paper evaluates three inter-vehicle spacing models based on exponential, Generalized Extreme Value, and Exponential with robustness factor statistical distributions [1], [2], [3]. Vehicles adjust transmission range as a function of its spatial density on a road segment to increase its network connectivity with other vehicles. This connectivity can be secured by deploying this scheme [4] which...
Smart Cities are often defined as systems of systems, where a heterogeneity of digital services oriented to the well-functioning of metropolises converge. It is essential to understand where, when and how much digital data is generated, since upstream traffic is progressively growing, in volume and share. One of the main challenges is how to work with continuous time digital communication services...
This paper targets to relate the latency and performance among the Linux CAN drivers that is Socket CAN and RTCAN which are the open source CAN drivers. Linux is one of the open source kernel which is moreover a cost effective and is the best alternative compared with other expensive patented RTOS. Socket CAN is added to Linux kernel mainline which is idealized by most CAN developers, however RTCAN...
The rapid increase in urban population due to the urbanization has led to one of the major problems in urban areas, namely, traffic congestion. With the constraint on road surface in urban areas and limited city budget, it is almost impossible to build additional streets and/or increase the road surface to support such the increase in urban traffic. As a result, a new technology known as Virtual Traffic...
In Vehicular Ad hoc Networks (VANETs), anonymity of the nodes sending messages should be preserved, while at the same time, the law enforcement agencies should be able to trace the messages to the senders when necessary. It is also necessary that the messages sent are authenticated and delivered to the vehicles in the relevant areas quickly. In this paper, we present an efficient scheme for fast dissemination...
This paper, addresses to the issues arising during the application of ITS. In this context, a study is done about chain collision and Intelligent Traffic Light Systems (ITLS). There is a need for these methods because nowadays, traffic causes traffic congestions which remain for long that is generally due to the inefficient management of road congestions. Vehicular Ad hoc Networks (VANETs) is a rising...
The DHL began test and research on delivery system by drone. Because of growing demand about comercialized and personal-use drone business, we needed a real-time unmanned drone control system that individuals can afford. In this paper, we propose an autonomous flight system for drone. We used marker recognition technique on that system because it doesn't require high-spec device which cannot be afforded...
The growing oil demands and the economic concerns have inspired the governments, car manufactures and the environmentalist to promote the manufacturing of Electrical Vehicles (EV). With developments in the power grid and advancements in the vehicle technology the EVs can contribute to the grid by selling or buying power from the grid. For the effective and efficient use of the V2G there is a major...
The paper is concerned with the comparison of four basic control strategies of the on-board energy storage system. The energy storage system is able to increase the tram efficiency and decrease operating costs. The comparing criteria are energy savings of strategies. Energy savings are calculated via stochastic model of the real tram line. Return on the investment is also estimated in this paper.
In recent years, many vehicle detection algorithms have been proposed. However, a lot of challenges still remain. Local Binary Pattern (LBP) is one of the most popular texture descriptors which has shown its superiority in face recognition and pedestrian detection. But the original LBP pattern is sensitive to noise especially in flat region where gray levels change rarely. To solve this problem, Local...
In this paper, we propose a hierarchical and hash-based naming scheme for Vehicular Information Centric Networks (VICNs). Our proposed naming scheme makes the best use of the features offered by hierarchical as well as hash-based naming schemes. The hierarchical part of the content name contains information about content owner or generator, content type, sub-types, and attributes of the digital content...
In this study, an active suspension system with multiple non-identical delayed resonators (DR) is proposed in order to, suppress vibrations that are caused by railway track irregularities. Mathematical models for a railway vehicle and track irregularities are given. In addition to this, methods on choosing the physical parameters and the design steps of multiple DR are mentioned. Simulations using...
This paper discusses the development of a public transit scheduling tool that can be run on a spreadsheet software. The main objective of the paper is to bridge the existing gap between the theoretical knowledge of bus service scheduling and local transport service providers in order for the latter to improve their service. Users of the tool are allowed to input onboard passenger counts, to analyze...
Effective in-vehicle icons are used to convey quick and complete understanding of information to drivers for safe driving; however, misunderstood icons may result to worse. Former studies were able to point out the ineffectiveness (in terms of matching accuracy) of non-ISO vehicle icons. This study was conducted to fill in the gap in literature that addresses the need for redesigning ineffective non-ISO...
We propose a method for reducing the communication requirements for electric vehicle (EV) charging control based on Vehicle-Originating-Signals (VOS). The original VOS approach requires a message exchange between every EV and the aggregator for every time step. This can cause the load on communication systems to increase, especially as the number of EVs increases and the control intervals become more...
The massive introduction of Electric Vehicles (EVs) is expected to significantly increase the power load experienced by the electrical grid, but also to foster the exploitation of renewable energy sources: if the charge process of a fleet of EVs is scheduled by an intelligent entity such as a load aggregator, the EVs’ batteries can contribute in flattening energy production peaks due to the intermittent...
