What to Know About V2V and V2I Technologies

Posted by Thom Rickert on April 11, 2018 at 9:36 AM

Through articles, presentations and news reports, you’ve probably heard about automakers developing and testing vehicles that require little or no human driver interaction. These highly automated vehicles, or HAV, will create a new paradigm in vehicle use, safety and insurance.

Realistically though, given the number of new automobiles sold annually and the industry’s manufacturing capacity, a total turnover to driverless cars is decades away.

Requisites for HAV to be effective

Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) technologies are requisites for the effective deployment of HAV. V2V involves the wireless transmission of data between motor vehicles, while V2I wirelessly connects motor vehicles to public infrastructure such as traffic lights and roadways.

If manufacturers and government entities can reach consensus on regulatory objectives and communications standards for these two technologies, they will likely be deployed more quickly than HAV.

How this can reduce a large number of accidents

The U.S. Department of Transportation estimates that V2V technology could reduce unimpaired driver accidents by as much as 80 percent and that V2I adds an additional 12 percent reduction in unimpaired driver accidents.

The advantage of speeding up deployment of V2V technology

One advantage in ramping up deployment of V2V technology versus HAV is that V2V can be installed after-market in existing vehicles at relatively low cost. Data tracked by V2V can include a vehicle’s position, speed, direction, braking and steering and can be communicated using visual cues, tones or vibration. Sharing this data with other drivers could prevent accidents caused by emergency braking, unsafe passing and confusion at intersections regarding right-of-way.

A motor vehicle communicating with infrastructure may increase compliance of traffic laws, improve traffic flows and reduce emissions from idling times. So, beyond safety, these technologies could also benefit road mobility and the environment.

New technologies will present new opportunities

Public entities will also see the benefits of V2V and V2I. These technologies can help expedite emergency vehicle responses, assign police to the highest priority crimes first and provide data for smart city planning.

New technologies will present new challenges

As with any innovation, the resulting change will present potential difficulties. A large majority of police stops are the result of traffic violations, meaning significant workload decreases may require difficult staffing decisions. Revenue from traffic fines will likely also decrease, affecting city budgets.

In addition, public entities must weigh the upgrade cost of smart infrastructure during their budgeting processes. This will require using complex calculations for the cost/benefit trade-offs in construction, staffing, maintenance and safety.

Other areas of concern cities should consider

V2V and V2I implementation could bring other daunting challenges regarding communication security, privacy concerns, platform standardization and critical mass of deployment

Even so, dozens of forward-looking communities are already using available federal grants, public/private partnerships and technology incubators to evaluate the impact of these exciting technologies.

Considering the potential for saving thousands of lives annually, this discussion should be on every community’s agenda.

I've been watching the dream of driverless cars and now the march toward highly automated vehicles. There is little question that the technology can be developed. My question is long term maintenance. I would guess that less than 5% of vehicle owners maintain the vehicles through the manufacturers' dealer networks and less than 50% of vehicle owners maintain every system on their vehicles in pristine condition. Considering all of the required software updates, system upgrades, and routine maintenance requirements, will the general populous be able to afford and actually use the technology long term? Will regulation require all vehicles on the road to have compatible systems or will they safely coexist on the same roadways with "dumb" vehicles? I used to have my own older, slower airplane but the FAA's requirements for upgrading communication and navigation systems priced it completely out of my ability to afford it. There is no question that the required upgrades enhanced safety and provided more capacity in the air. It just got too expensive to upgrade and maintain and I now watch others fly. (Working next to a general aviation airport and under the flight path keeps the dream going, but that's all it's likely to be.) Will regulation improve safety but price vehicle ownership out of the realm of those who need it?
