In this post, I wanna share with you folks the V2X technology.
Vehicle to Everything (V2X) is a vehicular communication system that supports the transfer of information from a vehicle to moving parts of the traffic system that may affect the vehicle. The main purpose of V2X technology is to improve road safety, energy savings, and traffic efficiency on the roads.
In a V2X communication system, the information travels from the vehicle sensors and other sources through high-bandwidth, high-reliability links, allowing it to communicate with other cars, infrastructure such as parking spaces and traffic lights, and smartphone-tossing pedestrians.
By sharing information, such as speed, with other entities around the vehicle, the technology improves the driver’s awareness of potential dangers and helps reduce the severity of injuries, road accident fatalities, and collisions with other vehicles.
The technology also enhances traffic efficiency by warning drivers of upcoming traffic, suggesting alternative routes to avoid traffic, and identifying available parking spaces.
The key components of V2X technology include V2V (vehicle-to-vehicle) and V2I (vehicle-to-infrastructure). V2V allows vehicles to communicate with other vehicles on the road, while V2I allows vehicles to communicate with external entities, such as traffic lights, parking spaces, cyclists, and pedestrians. The technologies help improve road safety, reduce fuel consumption, and enhance the experience between drivers and other road users, such as cyclists and pedestrians.
When V2X systems are integrated into traditional vehicles, drivers can receive important information about the weather patterns, nearby accidents, road conditions, road works warning, emergency vehicle approaching, and activities of other drivers using the same road.
Autonomous vehicles equipped with V2X systems may provide more information to the existing navigation system of the vehicle. The systems also make it possible for autonomous vehicles to scan the surrounding environment and make immediate decisions based on the information received.
The full benefits of V2X systems will take time to be realized because, for a vehicle to communicate with an entity, that entity must be equipped with V2X technology. Most entities like parking spaces, traffic lights, and traditional vehicles do not have the V2X systems, which means that they cannot communicate with the vehicles already using the system.
As the V2X market expands, vehicles will be able to communicate with other vehicles, traffic systems, and other road users like cyclists equipped with V2X systems.
The IEEE 802.11p is the original V2X standard, and it uses WLAN technology. It links vehicles-to-vehicles (V2V) and vehicle-to-infrastructure (V2I) when two V2X senders get close to each other’s range. The 802.11p standard does not require any communication device for it to work, and such a capability makes it ideal in less-developed areas.
The IEEE 802.11p standard exceeds the line of sight sensors, such as radar and camera, and it delivers information such as toll payments and collision warnings. The key characteristics of 802.11p include low latency, short-range (under 1 km.), and it runs in the unlicensed 5.9GHz band.
In addition, the standard delivers performance without being affected by weather conditions, such as fog, rain, or snow, and the technology can scan the surrounding environment even in adverse weather.
