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.
Emergency occur in our country countless. In the territory of the Slovak Republic, the main causes of road traffic damage are floods. From the individual sources of information, one of the other ...causes of the damage is the flood wave, the submergence of the road and, last but not least, the landslide. The main triggering floods in our territory are extreme precipitation, rapid warming at high reservoirs of snow in the catchment area and, of course, torrential rainfall. These risks can seriously endanger the environment, the material values, but also the safety of life and human health. The gradual process of rehabilitation of damaged roads provides for the reduction of material losses on property and the environment and, of course, to increase the safety of the population in the affected area by an extraordinary event.
Acceptance of new technology and systems by drivers is an important area of concern to governments, automotive manufacturers and equipment suppliers, especially technology that has significant ...potential to enhance safety. To be acceptable, new technology must be useful and satisfying to use. If not, drivers will not want to have it, in which case it will never achieve the intended safety benefit. Even if they have the technology, drivers may not use it if it is deemed unacceptable, or may not use it in the manner intended by the designer. At worst, they may seek to disable it.

Every day, thousands are injured and almost 350 people are killed on the roads of OECD countries. New technologies could reduce this toll by as much as 40%. However, considerable challenges need to ...be overcome in order to achieve these benefits. Billions of dollars are currently being spent to develop new technologies which are not related to safety, and many of these may have a negative impact on road safety if action is not taken to ensure their compatibility with current road systems. This report evaluates the global impact of new technologies on road safety and provides recommendations to governments and industry to ensure that fatalities and injuries in road traffic are reduced.
This groundbreaking resource offers you a comprehensive overview of cutting-edge intelligent vehicle (IV) systems aimed at providing enhanced safety, greater productivity, and less stress for ...drivers. Rather than bogging you down with difficult technical discourse, this easy-to-understand book presents a conceptual and realistic view of how IV systems work and the issues involved with their introduction into road vehicles. Helping you apply your skills to this emerging field, this practical reference offers you a thorough understanding of how electronics and electronic systems must work within automobiles, heavy trucks, and buses.
