Vehicular Communications Utility in Road Safety Applications: A Step toward Self-Aware Intelligent Traffic Systems

Abstract

The potential of wireless technologies is significant in the area of the safety and efficiency of road transport and communications systems. The challenges and requirements imposed by end users and competent institutions demonstrate the need for viable solutions. A common protocol by which there could be vehicle-to-vehicle and vehicle-to-road communications is ideal for avoiding collisions and road accidents, all in a vehicular ad hoc network (VANET). Ways of transmitting warning messages simultaneously by vehicle-to-vehicle and vehicle-to-infrastructure communications by various multi-hop routings are set out. Approaches to how to improve communication reliability by achieving low latency are addressed through the multi-channel (MC) technique based on two non-overlaps for vehicle-to-vehicle (V2V) and vehicle-to-road (V2R) or road-to-vehicle (R2V) communications. The contributions of this paper offer an opportunity to use common communication adaptable protocols, depending on the context of the situation, coding techniques, scenarios, analysis of transfer rates, and reception of messages according to the type of protocol used. Communications between the road infrastructure and users through a relative communication protocol are highlighted and simulated in this manuscript. The results obtained by the proposed and simulated scenarios demonstrate that it is complementary and that the common node of V2V/V2R (R2V) communication protocols substantially improves the process of transmitting messages in low-latency conditions and is ideal for the development of road safety systems.

Inter-Urban Analysis of Pedestrian and Drivers through a Vehicular Network Based on Hybrid Communications Embedded in a Portable Car System and Advanced Image Processing Technologies

“…This process allows the vehicle to design a three-dimensional model of the area in which it is identifying objects within its range. We consider the evolution of this significant field, and we try to incorporate into intelligent systems all the technologies of the future, whether we are talking about V2V, V2I, V2R, V2X, or VLC [18,19]. The current situation shows that most vehicles benefit from sensor-based equipment that can participate in crowdsourcing applications.…”

Research on the Impacts of Generalized Preceding Vehicle Information on Traffic Flow in V2X Environment

“…In the last few years, the informatization degree of traffic system has been substantially increasing with the application of intelligent and connected technologies. The new generation connected technology including the C-V2X as well as the ITS-G5 can transmit information between vehicles, facilities and other elements in the transportation system in a low-latency and high-reliability way [1][2][3][4][5][6][7][8][9], which makes it possible for drivers to obtain massive information about elements in the system in real time. A larger number of efforts were carried out to explore the impacts of the new connected technologies on the operation of the transportation system [10][11][12][13][14][15].…”

Geometry-Based Channel Modelling for Vehicle-to-Vehicle Communication: A Review

“…It attempts also to monitor traffic information which can be utilized to reduce road congestion. In addition, it helps to predict and avoid accidents, and it automates driving process by improving road safety and efficiency [3][4][5]. Most V2V studies use the 5.9 GHz spectrum which has been allocated by the United States and Europe for these types of communications [4,6].…”
