A subset of IoT vehicle telemetry, V2X technology refers to the communication between vehicles on the road and other compatible objects. Within V2X, which stands for vehicle-to-everything, V2V refers to vehicle-to-vehicle communication while V2I refers to vehicle-to-infrastructure—which includes both streetlights and pedestrians.
The primary purpose of V2X technology is safety. By communicating with other cars or inanimate objects, V2X-enabled vehicles avoid accidents. One of the greatest advantages for safety, in fact, is that the short-range wireless signals used by V2X tech allows communication with objects that cannot be seen by the human eye—for example, a car accelerating wildly around a building corner before the driver makes a turn.
Additional, related uses of V2X technology include toll collection and the recovery of stolen vehicles.
Some useful internal V2X data includes gas or electricity usage, speed, acceleration, scheduled maintenance, direction travelled, and necessary vehicle repairs. All of these factors inform the possibility and danger of an accident or inconvenience (for example, running out of fuel before reaching a destination).
The presence of other vehicles and V2X technology infrastructure are essential, of course. But other vital data include weather, road conditions, and the presence of accidents or traffic on the road ahead.
Additional external data are emitted by infrastructure: for example, street lights, toll bridges, and traffic cameras. Thankfully, municipalities increasingly upgrade their infrastructure with this technology to improve safety.
Finally, whenever possible, include data from devices worn or carried by cyclists and pedestrians so they can also avoid accidents.
As noted in the previous paragraph, not every person has a V2X-compatible device; older vehicles and infrastructure certainly didn’t come with the technology that made it possible and their owners may not have the budget for an upgrade.
Additionally, the wireless signals that provide V2V and V2I data are vulnerable to interference and to inclement weather.
Finally, even when devices can exchange data freely, integrating the information and providing it to vehicle operators in real-time so people can use it remains a challenge. Thankfully, new technology shows that this can be overcome—but it is still a challenge.
Yaniv Sulkes, vice president of business development at Autotalks, said: “Ultimately we all want to get from point A to point B safely and if you get an alert ahead of a potential hazard you can avoid the accident. This is the underlying principle of what we do.
Loqate Geo+ allows you to make faster and more accurate deliveries. It does this by aligning longitude and latitude with the combination of geocodes, UPRNs (Unique Property Reference Numbers), and UDPRNs (the Royal Mail’s 8-digit reference number). Every UK address will soon have a roof-top geocode.
Data Security and Interoperability services provided by EcoSteer work to provide shareable data streams for businesses.
IBM PAIRS Services provides queryable geospatial and temporal data in the form of maps, satellite images, weather data, drone data, and other data.
Factual Global Places is a proprietary data set of billions of points of interest via 100,000+ unique sources. This data set contains over a hundred million place records in over fifty countries for your marketing, delivery, or other business use.
Loqate Address Capture verifies addresses as soon as a business name, street name, or zipcode is typed—whether it was spelled correctly or not. The database has geolocation data on over 245 countries and partners with UK’s Royal Mail, Canada Post, Australia Post, and the US Postal Service and is free for up to five addresses per IP per day.
Address Capture also offers mobile customers the ability to search for an address through a tap on their phone screen.
