ITS graphical user interface displaying the Hungarian highway network and its data points. An intelligent transportation system (ITS) is an advanced application that aims to provide services relating to different modes of transport and traffic management and enable users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks.
Vehicles are enabled to communicate among themselves (vehicle-to-vehicle, V2V) and via roadside access points (vehicle-to-roadside, V2R) also called as Road Side Units (RSUs). Vehicular communication is expected to contribute to safer and more efficient roads by providing timely information to drivers, and also to make travel more convenient.
It has been shown that vehicle-to-vehicle and vehicle-to-roadside communications architectures could co-exist in VANETs to provide road safety, navigation, and other roadside services. VANETs could be a key part of the intelligent transportation systems (ITS) framework. Sometimes, VANETs are referred to as Intelligent Transportation Networks. [3]
Vehicle-to-everything (V2X) describes wireless communication between a vehicle and any entity that may affect, or may be affected by, the vehicle. Sometimes called C-V2X , it is a vehicular communication system that is intended to improve road safety and traffic efficiency while reducing pollution and saving energy.
Internet of vehicles (IoV) is a network of vehicles equipped with sensors, software, and the technologies that mediate between these with the aim of connecting & exchanging data over the Internet according to agreed standards.
Numerous subsequent projects have been implemented all over the world such as the Advanced Safety Vehicle (ASV) program, [6] CHAUFFEUR I and II, [7] FleetNet, [8] CarTALK 2000, [9] etc. In the early 2000s, the term Vehicular Ad Hoc Network (VANET) was introduced as an application of the principles of Mobile Ad-Hoc Networks (MANETs) to the ...
An ATIS may operate through information supplied entirely within the vehicle (autonomous system) or it can also use data supplied by the traffic management centres. Relevant information may include locations of incidents, weather and road conditions, optimal routes, recommended speeds, and lane restrictions, all part of the Intelligent ...
The vehicle-based option could be updated via the internet (preferably wireless) but may subsequently require all users to have access to internet technology. Alternatively, if receivers were placed in all vehicles and the VII system was primarily located along the roadside, information could be stored in a centralized database.
