An expert on intelligent transportation gave his perspectives on what’s happening with V2X – which is the crossroad where Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) services come together. It’s communication between drivers, vehicles, road sensors, signage, telematics, and even pedestrians, into one interactive communications network. It deals with core issues – safety, traffic congestion, fuel consumption, and emissions.
Intelligent Transportation Society (ITS) of America is an NGO that initially started out in 1991 as a federal advisory committee to the US Dept. of Transportation. All of the major automakers belong to it, along with major federal, state, regional, and municipal government transportation agencies, AAA chapters, technology suppliers, universities and research centers, and consultants.
Steven Bayless, Senior Director, Telecommunications and Telematics at ITS America, talked about why a common platform for vehicle communications will provide more opportunity for the industry than individual OEM solutions. All of the passenger and commercial vehicles on the road need to be integrated into the right web of communications.
Here’s a few of the issues he talked about…
- The US DOT would like to see aftermarket devices that provide some safety application capability – V2V communications using a brought-in device that would allow current passenger cars to provide some functionality to those vehicles right away, rather than to wait for automakers to install capability in new vehicles.
- Another path is infrastructure, introducing roadside units at intersections running intersection applications to encourage uptake of the technology in vehicles and even perhaps aftermarket devices.
- Another possible strategy is the inclusion of other types of road users, for example, motorcycles and perhaps pedestrians that might carry dedicated short-range communications capability in their mobile phones.
- Most folks involved in the program don’t think mobile phones would be perfect substitutes for a factory-installed system. He thinks there are a lot more applications that can be supported from an OEM-installed system than could be supported from a mobile device system. Mobile devices are more constrained in terms of capability, the accuracy of GPS, and they are battery-constrained and don’t have as much power.
- The potential for V2X is much greater than the potential for some of these other technologies, which are more single-purpose and more expensive. They think that V2X will be able to create a platform that will allow many more crash-avoidance and mobility applications to be supported simultaneously.
