A context-based vehicular communication protocol

Research in traffic safety has indicated that active safety systems provide a better service to drivers when they use data about nearby vehicles. For supplying such information inter-vehicle communication is employed. In this paper we propose a distributed communication protocol that allows the vehicles to organize the communication network in a decentralized manner. For information dissemination we use an anonymous context-based broadcast protocol. The receivers determine whether they are the intended destination of sent messages based on knowledge about their local environment. Simulation results indicate that the proposed protocol performs well in terms of communication performance and filtering of the received information.

Vehicular communication - a candidate technology for traffic safety

Research in traffic safety has indicated that in-vehicle safety systems provide a better service to drivers when they use data about nearby vehicles. For supplying such information, vehicular communication can be employed. However, the development of in-vehicle safety systems is currently at an early stage, and the applicability of the communication between vehicles for improving traffic safety is still under investigation. This paper provides an analysis of the role of communication for implementing traffic safety services. We survey approaches to vehicular communication and identify the most appropriate alternative for developing active safety systems that implement safety functions such as collision warning and collision avoidance.

A novel architecture for supporting vehicular communication

In todays world, traffic safety is a major problem. Traffic accidents result in more than half a million casualties each year and are associated with serious injuries and extensive material losses. Therefore, special attention is given to those technologies that can reduce the number and severity of road events. Inter-vehicle communication (IVC) and vehicle to road communication (VRC) are considered to have extensive potential for the development of efficient safety systems installed in vehicles. This paper proposes a novel, safety-oriented communication platform dedicated to supporting the exchange of safety-relevant information between traffic participants. The vehicular communication platform (VCP) aims to support a specific vehicular communication mechanism previously designed by the authors and briefly presented in the paper.

On the Design of Safety Communication Systems for Vehicles

Statistics show that the number of casualties due to traffic accidents exceeds one million each year. For the development of systems that prevent vehicle collisions, vehicular communication is considered a promising technology. This paper focuses on design aspects of communication systems that support the development of collaborative active safety systems such as collision warning and collision avoidance. We introduce a design method for safety communication systems that includes a set of analyses and a reasoning system for modeling and analyzing traffic scenarios. An overview of a specific solution for communication is presented in this paper. This solution proposes techniques for network organization and data dissemination that make use of contextual information. This allows the development of a communication system that is adaptable to the specifics of the traffic situation.

An in-vehicle approach for improving traffic safety through GIS utilization

This paper focuses on the utilization and integration of geographic information systems (GIS) oriented to tragic safety in vehicles. We have primarily analyzed the benefits of introducing GIS systems that support the driver and provide processed data to collision warning and collision avoidance systems located in vehicles. Further on, we have defined a set of information that is relevant for traffic safety and appropriate to be used within an in-vehicle GIS system. Based on these data, we propose in this paper a specific design for the GIS system. This system integrates the relevant data for traffic safety and takes into consideration the specific requirements of the vehicular domain. The integration of the GIS system within vehicles introduces a series of problems that are discussed in the paper.

Adaptive Dissemination of Safety Data Among Vehicles

In-vehicle active safety systems are directed towards reducing the number of accidents or at least alleviating their consequences. One of the key technologies for developing these systems is safety vehicular communication. This paper proposes an adaptive approach to dissemination of safety data among vehicles. This data is then used by systems in vehicles for identifying hazards in traffic and reacting to them. We propose a proactive protocol that makes use of contextual information for adapting the communication to the specifics of the traffic situation. Communication performance is investigated via simulations and indicates that efficient vehicular communication can be provided by the proposed protocol

Traffic accidents modeling and analysis using temporal reasoning

Traffic accidents account for more than half a million casualties every year. The analysis of accidents helps identifying the elements that affect traffic conditions, the relationships between them, and how they may contribute to the occurrence of dangerous situations. In this paper, we present a temporal reasoning system for modeling and analyzing various types of accident scenarios. The system is based on event calculus and was implemented using Prolog. We exemplify the use of the system by applying it for modeling and analyzing a rear-end accident scenario.
