Vehicular ad hoc network is widely used to broadcast emergency, weather and road conditions among vehicles. In this paper, an algorithm is proposed to transmit weather information to the vehicles which are travelling in urban areas. The system uses a set of algorithms and rules to determine dangerous weather situation on roads. It is proposed to use Weather_Forecast algorithm to predict the weather...
Travelling is one of the daily routine activities for most people. In the recent studies that were identified, we found many uses for the smartphone in smart diver application on the environment. However, the energy is the key challenge for our planet. We also found that very few high-quality studies exist to help us understand how best to use this technology. Taking account that users are using smartphones...
Connected vehicles extend the capability of information collection, and thus open more opportunities for innovative advanced driver assistance systems (ADAS). In this paper, we propose a Lane Speed Monitoring (LSM) application based on vehicle-to-vehicle (V2V) communication. This application takes advantage of Basic Safety Messages (BSM) transmitted from equipped vehicles via dedicated short range...
In the current day and age, traffic in urban areas is becoming more and more complex leading to congested roads and intersections. Hence, the need for sophisticated traffic control system to reduce the congestion and provide better flow management. In this paper, we present briefly the basic notions and the most important parameters that affects the traffic control. Then, we provide a survey on the...
A wireless sensor network (WSN) is a specific technology that helps in creating smart cities. Their aim is consists in creating a network containing many nodes of intelligent sensors that can measure multiple parameters of interest for better city management, and a control of urban traffic (fluidity of traffic at an intersection). Each network node exhausts its energy because the battery capacity...
Vehicles equipped with various types of sensors can act as mobile sensors to monitor the road conditions. To speed up the information collection process, the monitoring data can be shared among vehicles upon their encounters to facilitate drivers to find a good route. The vehicular network experiences intermittent connectivity as a result of the mobility, which makes the inter-vehicle contact duration...
Maseru is the capital city of Lesotho and is a relatively small city with roughly 67 vehicles registered each day. Traffic lights are used with the intension of effectively managing vehicular traffic at junctions. These traffic lights follow a predetermined sequence usually based on historic data. As a result of this design, they inherently fail to efficaciously manage traffic flow when it is abnormal...
Traffic management has become more complicated because increasing road networks and vehicles day by day due to population increasing. Monitoring and tracking of movable vehicles is one of the most comprehensive issues. Decision support system for traffic management is the key points of intelligent transportation system. In this paper we propose the decision support system for handling traffic by using...
The vehicular networks represent an innovative and a promising research area. They contribute in the realization of ITS (intelligent transportation systems) to improve road safety and to provide various services and applications for both drivers and passengers. Several applications require knowledge of vehicle's positions such as target tracking. In a previous work, an approach for tracking exploiting...
The highly anticipated era of Internet of Things (IoTs) expected to empower all aspects of Intelligent Transportation Systems (ITS) will undeniably improve transport safety and significantly reduce road accidents. To promote the communication of mobile vehicles (or IoVs), US FCC officially allocated a merger 75 MHz spectrum in the 5.9 GHz band to enable vehicular communication. In this paper, we studied...
Overtaking traffic on undivided roadways is one of the major causes of accidents that results in fatalities and severe injuries. This is especially true in developing countries such as India, where roads are narrow, yet traffic is heavy and fast. The primary cause of such accidents is the inability of drivers to gauge the speed and distance of oncoming traffic as well as the impairment of vision due...
Vehicular ad hoc network is an emerging tremendous technology that facilitates ubiquitous wireless communication between vehicles and possibly with road side infrastructure to providing safety, driver assistance and comfort. Real-time vehicular information gathering is a significant and crucial part in vehicular communication about vehicle position and velocity, etc. For broadcasting and gathering...
An intrusion detection system was developed to detect illegal entries to guarded forest areas and thus help the prevention of timber theft and other damages, caused by illegal activities. The system contains accelerometers, magnetometers and geophones to provide high detection reliability and fast reaction time. The performance of the proposed system is illustrated by real measurements.
The area of the state of Oregon has 98,381 square miles, which is the 9th largest in United States. Its population ranks 27th in United States, and most of its population residents in the Willamette valley, a narrow area north to Portland and south to eugene and home to eight of ten most populous cities in Oregon. This implies that most of Oregon are rural areas. It is necessary to design and deploy...
Driving at night is one of the leading causes of traffic related deaths. The lack of adequate light at night impairs a driver, preventing him/her from being able to judge distances between objects accurately as well as preventing a driver from recognizing various objects on the street and avoiding them. Additionally, high intensity light from the headlights of oncoming vehicles causes temporary blindness,...
The proposed approach of Vehicle Regulatory System (VRS) using wireless vehicle terminal unit (VTU)∗ is based on communication between a Vehicle Terminal Unit and the Outside Terminal (OT). The VTU is placed in the vehicle and sends continuously vehicle basic information code through radio frequency signals in all directions. These signals are captured by the OT (which is connected to outside world)...
The article is dedicated to the analysis of design of WSN road transportation system for developing applications related to parking management, traffic flows and emergency vehicles monitoring, weather and environmental conditions monitoring as well. The analysis is done for all units of sensor node. Many technical aspects of the design are discussed in the paper.
Vehicle speed monitoring and management of the associated data in an intelligent and efficient way is an important issue in modern transportation system in order to reduce road accidents. The aim of this work is to develop an automatic wireless system for monitoring vehicle speed on the road, identify a speeding vehicle and imposing penalty for the speeding offenders. In this work, a prototype system...
Considering vehicles as sensors is a new paradigm introduced by Intelligent Transportation Systems. This paper focuses on utilising standards such as IEEE 802.11p developed for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) purposes in a self-reporting mass distance charging application for heavy vehicles. An axle mounted hub-odometer based device is proposed. The system is based on...
Plague of modern times, the phenomenon of the trafic accidents hampers heavily resources of the society. The road mows every year thousands of deaths and tens of thousands wounded. This frightening number of victims requires a study of this phenomenon in order to extract all indicators affecting this problem and allow proposing preventive measures. Most current studies ignore the integration of geographic...
