[00:00:01.210]A highway in rural America can be deadly.
[00:00:04.360]About 70% of fatalities in single vehicle crashes
[00:00:08.247]occur when a vehicle leaves the road or lane.
[00:00:12.326]That type of accident is more common in rural areas.
[00:00:15.967]A University of Nebraska computer science engineer
[00:00:18.533]wants to make roads safer.
[00:00:21.679]We're working on vehicular to barrier communications
[00:00:24.957]that will enable smart barriers.
[00:00:28.510]John Vuran wants to arm cars
[00:00:30.150]and roadside safety barriers
[00:00:31.708]with technology that alerts drivers before impact.
[00:00:37.036]We can at least either prevent crashes altogether
[00:00:40.659]or we can mitigate the impacts of the crashes
[00:00:44.128]because the vehicles will have even more information
[00:00:47.998]than they get it on their own,
[00:00:49.928]they can communicate with the barriers
[00:00:51.665]and then we make better decisions
[00:00:54.189]based on those information that we get.
[00:00:56.656]Radios equipped with software
[00:00:58.307]provide new functionalities
[00:01:00.020]that could enhance current smart car technology.
[00:01:03.759]With the software-defined radios
[00:01:05.093]we also start to talk about cognitive radios,
[00:01:08.747]cognitive radio networks.
[00:01:11.067]These are radios that can be aware of their surrounding,
[00:01:14.997]especially in terms of the spectrum
[00:01:17.319]and accordingly they can change their configuration
[00:01:20.219]on the fly and have a better communication.
[00:01:23.449](crashing)
[00:01:24.929]Crash testing at Nebraska's Midwest
[00:01:26.581]Roadside Safety Facility
[00:01:28.498]helps researchers refine the technology.
[00:01:31.974]The Midwest Roadside Safety Facility
[00:01:33.907]is one of the leading roadside safety facilities.
[00:01:37.778]They're especially focusing on highway barrier design
[00:01:42.388]and they're actually helping with certification,
[00:01:45.175]helping with design of new barriers
[00:01:47.220]and that is a very unique capability to have here.
[00:01:51.845]Vuran's research
[00:01:52.678]could also lead to improvements
[00:01:53.991]in high-speed communication
[00:01:55.557]for aircraft or drones
[00:01:57.554]but the best contribution may be on the rod.
[00:02:01.150]We will be able to say hopefully
[00:02:03.313]that we can prevent crashes,
[00:02:06.140]we can prevent fatalities.
[00:02:08.259]That's the most important reward you can get
[00:02:10.347]from your research.
