V2V Stops Here - No Module Mandate Needed

by Roger Lanctot | Aug 20, 2014

The U.S. Department of Transportation is seeking to mandate the installation of a device in cars for vehicle-to-vehicle communications. For some reason the agency fails to perceive that there is already a life-saving device in the car. That device is called a wireless phone.

The wireless phone is typically acquired voluntarily by the driver. It is capable of communicating with other drivers as well as with law enforcement and emergency responders. It is also capable of receiving emergency alerts.

Depending on how the phone is configured it can be set to automatically make emergency calls. And in some cars – notably from Chrysler and Ford in the U.S. – the phone can make approved automatic crash notification calls to summon assistance in the event of a collision.

The wireless phone is normally equipped with the latest wireless network technology and is therefore never at risk of being outmoded by a transition to new technology or by the shutoff of a particular network or piece of wireless spectrum. The device is also possessed of extraordinary processing power and a variety of sensors for positioning and location. It is also equipped for voice, data, video, and text communications.

The device itself is usually replaced on a regular basis to take advantage of advances in technology. Software updates for the device are free of charge and accomplished safely whether the device is in use or not.

Applications exist to enable the wireless phone to communicate with infrastructure and with other vehicles. And some apps (Global Mobile Alert) will alert drivers (who may be distracted by wireless phone calls) to dangerous driving circumstances such as the proximity of intersections or railroad crossings.

Wireless phones using applications such as Driveway can evaluate driving behavior and provide suggestions for safer driving behavior. Multiple applications are available for tracking location via the mobile phone for worried family members or friends as well as to alert them based on geo-fencing.

But the very best aspect of the wireless phone is that it is brought into the car voluntarily at no added cost to the car maker or customer. Deployment of the technology is immediate as are the benefits. Best of all it is demand-driven – no coercion is required.

Even better, no prototyping, testing, or assessment of user interfaces is needed. And there is no requirement for dedicated, protected spectrum or protracted comment periods for car makers, consumers or suppliers. No new standards, consortia, testbeds or congressional hearings.

Bottom line: The U.S. Department of Transportation needs to take a closer look at wireless phones as a means for achieving communications between vehicles or between vehicles and their drivers and infrastructure. Mandating a module is a dead end deal.
