We discuss the need for taking the environmental impact as a primary metric for evaluating the quality of algorithms for Intelligent Transportation Systems (ITS). In many studies, the travel time, or its minimization, has been used to demonstrate the advantages of Inter-Vehicle Communication (IVC) solutions combined with dynamic rerouting. Such evaluations are frequently based on simulation experiments...
This paper describes a cooperative MANET protocol dedicated to intelligent transportation systems and its new experiment results in mobile scenarios. The protocol is named CIVIC (Communication Inter Veacutehicule Intelligente et Coopeacuterative). It is an auto-configuration inter-vehicle communication protocol, which supports ad-hoc and infrastructure networks, contains reactive and proactive routing...
Wireless mesh networks (WMN) is poised to be a cost-effective platform for many municipal applications in public safety, business and entertainment. In this paper we present WMN-based platform for content delivery within Intelligent Transportation Systems (ITS) applications. An example ITS application would be to deliver content used for vehicle route guidance in emergency evacuation situations. The...
Cooperative collision warning system for road vehicles, enabled by recent advances in positioning systems and wireless communication technologies, can potentially reduce traffic accident significantly. To improve the system, we propose a graph model to represent interactions between multiple road vehicles in a specific region and at a specific time. Given a list of vehicles in vicinity, we can generate...
Future active-safety applications in vehicular networks rely heavily on the support for real-time inter-vehicle communication. The medium access control (MAC) mechanism proposed for the upcoming IEEE 802.11p standard intended for intelligent transport systems (ITS) applications does not offer deterministic real-time support, i.e., the channel access delay is not upper bounded. We therefore propose...
Vehicular networks are the major ingredients of the envisioned intelligent transportation systems (ITS) concept. An important component of ITS which is currently attracting wider research focus is road traffic monitoring. The actual approaches for traffic road monitoring are characterized by longer response times and are also subject to higher processing requirements and possess high deployment costs...
Safety is evergreen vital criteria for road traffic. We propose an infrastructureless solution based on contexts to increase safety of vehicle. Contexts characterize and track the moving environment of a vehicle. Here, environment means the vehiclepsilas own status like geographical position, break-controlpsilas functional status, driverpsilas status etc., and the status of neighboring vehicles. Contexts...
Communication of vehicle information to neighbor vehicles is an important factor for safe driving systems in intelligent transport system. Additionally, big-size vehicles on the real road environments may interrupt communication between vehicles. Therefore, an adequate vehicle should forward the vehicle information in the delivery of the vehicle information to neighbor vehicles. This paper proposes...
Recent advancements in wireless communications and electronics have caused the emergence of a new type of networks called Wireless Sensor Networks (WSNs). WSNs have some unique features such as autonomy, low cost, tiny size, simple and fast deployment and high scalability, and many applications have been forecasted for them. In recent years, many WSN-based applications were proposed for Intelligent...
Vehicle overspeed is an important reason for the traffic accident on the freeway and it is helpful and necessary to monitor the peccancy behavior of over speed. In this paper, design method of the overspeed wireless monitoring system based on GPRS (general packet radio system) is discussed, and the configuration of its hardware and software is introduced. The whole system consists of the subsystems...
