European light duty vehicle emission legislation is gradually shifting the focus from test procedures with merely static test cycles, towards procedures including Real Driving Emissions (RDE), as they are a mean to achieve the European (NOx) emission reduction target. Hence a RDE trip must represent European driving behavior, such that "real world driving" emissions can be assessed. However,...
Enabling efficient vehicular wireless connections with wide coverage for vehicular applications has gained significant attentions in both academia and industry. In this paper, we study the TV white spaces (WS) supportive vehicular content distribution with Geolocation database, which is referred to as WhiteFi Infostations. Taking into account both the realistic content distribution requirements for...
One of the important issues in postal business in Korea is to distribute the delivery areas equally and to calculate optimal delivery routes to reduce delivery cost. However, it is difficult problems because postal managers distribute the delivery areas by heuristic methods and postmen have simply decided optimal delivery routes b y the ir experiences. Also raw data of delivery activity log have not...
Transportation in Lima is one of the most chaotic in the world. A transportation reform plan in the city of Lima is underway. After this process the traffic in the city should be controlled. However, many years could be spent before reaching that goal. Until that happens, the citizens need accessible solutions now. An alleviation to the problem is solving the lack of official traffic data. This project...
At present, many businesses use the advertising emails to communicate with their customers for various objectives. Often advertising emails are sent to unwanted recipients that might be from not up-to-date recipient list or bad senders. Currently, the methods of classifying the sender whether they are good sender or not have still been ineffective. Such events can lead to annoyance to the recipients...
Most electric power companies employs power meter reader to collect data on the customer's energy consumption. Usually, this task is carried out manually, which can lead to high cost and errors, causing financial losses. Some approaches trying to minimize these problems, such as: discover the minimal route or use a car to perform the readings. However, errors associated the manual readings can still...
At present, the collection of connected vehicles data is not a problem any more but the platform and visualization are the most needed for traffic data. Management of the collected data, platform operation, and visualization technology are the topics of this paper. Through using the new ECharts data visualization tool, we could achieve large data in real-time display with an ordinary WEB browser.
The road safety and maintenance are very important and costly activities for road operators. Due to the decrease in the cost of the sensors technologies and wireless equipments, connecting maintenance fleet vehicles become very intuitive. It allows to enhance the efficiency and the reactivity of such services. In the present paper we describe an interconnection system that facilitates the data exchange...
Lately, the development of the Electric Vehicle (EV) has become a strategy to soften the collateral damages of the environment pollution. However, the forecasts of a wide EVs deployment, establish a stress that has to be carefully analyzed in distribution systems. Whereby, the need arises of researching respect to the effects of EVs on electric grids since different perspectives. This paper presents...
In this demonstration paper, we will present our adaptive user interface for replacing a vehicle's conventional dashboard. A programmable tablet computer with the Android operating system was utilized for displaying a vehicle's conventional instrumentation data and navigation guidance, as well as notifications from the vehicle's local safety sensors or external infrastructure. The developed user interface...
Counting of passengers in public transport system is a very significant task which must be performed for sustainable city planning. In different countries and cities this task performed very differently, or not performed at all, as well as there are no clearly defined international standards for public transport passenger flow analysis, and as a result, for system sustainable development. There are...
In this paper, we present a mobility cloud platform called CarCloud that has been designed to facilitate the real-world deployment of ubiquitous mobile telematic applications to promote smart transportation. CarCloud leverages the mobility, sensing and communication capacities of mobile devices, and collaborates with sensors embedded in vehicles (e.g., accessed via OBD-II) and cloud services to form...
We describe three in-field data collection efforts yielding a large database of RSSI values vs. time or distance from vehicles communicating with each other via DSRC. We show several data processing schemes we have devised to develop opportunistic Vehicle-to-Vehicle (V2V) propagation models from such data. The database is limited in several important ways, not least, the presence of a high noise floor...
Automatic text extraction from number plates is used in most of the countries in present. In this paper a semiautomatic text extraction from Sri Lankan vehicle number plates is presented. There are several number plate types currently available in Sri Lanka. First a set of template was created based on the font used in the number plates for all the English letters and numbers. Number plate first corrected...
Research in traffic light recognition (TLR) has stagnated compared to related computer vision areas, such as pedestrian detection and and traffic sign recognition. We focus on the detection sub-problem, since this is the most challenging problem and solving this is the key to a successful TLR system. This is done by looking at four detectors from different author groups and their reported results...
Nowadays, electronic toll collection (ETC) is used extensively in many countries and places, but many drivers evade detection by covering, altering or otherwise obscuring their license plates. In order to detect vehicles attempting to evade paying tolls, this study aims to identify vehicles without requiring the license plate information. Unlike traditional vehicle license plate recognition, in this...
This paper investigates a multi-agent formation control problem with event-triggered control updates and additive disturbances. The agents communicate only by exchanging information in a cloud repository. The communication with the cloud is considered a shared and limited resource, and therefore it is used intermittently and asynchronously by the agents. The proposed approach takes advantage of having...
In electric vehicle (EV) charging, the goal is to compute a charging schedule that meets all user specifications while minimizing the influence on the power grid. Usually, an optimal schedule is computed by a central authority (called mediator) according to the specifications reported by the users. A desirable property of this procedure is to ensure that participating users truthfully report their...
In recent years, as a demand for communication services over the VANET (Vehicle Ad-hoc Network) is increasing drastically, radio frequencies to be assigned to the new communication services are becoming insufficient. In response to this problem, we consider to apply the cognitive radio technology in general, and the cognitive use of TV white space based on the white space database (WSDB) in particular,...
In Dynamic Ensemble Selection (DES) techniques, only the most competent classifiers are selected to classify a given query sample. Hence, the key issue in DES is how to estimate the competence of each classifier in a pool to select the most competent ones. In order to deal with this issue, we proposed a novel dynamic ensemble selection framework using meta-learning, called META-DES. The framework...
