A competition to help influence new drone technologies is
being put together by Air Force Research Laboratory (AFRL) and the United
Kingdom’s Defense Science and Research Laboratory. The competition will find
the best drone design to help with fighting wildfires, and will use new drone
technologies such as drone swarms. The competition is being called the “Swarm
and Search AI Challenge: Fire Hack” and is designed to promote drone swarm
technologies used in a real world scenario. Drones, or Unmanned Aerial Vehicles,
are becoming more and more popular for many different applications. Their small
size and simple design bodes well for situations unsuitable for humans, and new
technologies are turning drones into massively capable little machines.
The idea of drone swarms is a relatively new concept. A
drone swarm would consist of a large number of independently flying drones that
are computer controlled. The drones would all be “aware” of each other to avoid
in-air collisions, be fully autonomous, and would be able to fly together in
close proximity, with the same goal of each delivering a small payload, perform
widespread searches of an area, of other related functionality. It’s easy to
envision how drones could be effectively used to fight wildfires: the drones could
deliver a fire suppression payload quickly and effectively, and a drone swarm
could cover a large area of wildfire.
Aside from the above mentioned usage, the Swarm and Search AI Challenge: Fire Hack competition aims to show how drone swarms could be used to effectively map out a wildfire area from a safe location. Benefits of using multiple drones for mapping include the ability to cover a large area quickly, and the ability to create almost real-time updated maps of wildfire spread in an area that would otherwise be too dangerous for firefighters to enter. Capabilities discovered during the challenge may be further developed for military applications. The competition will culminate in March, 2019.

The nation saw a slight decline in traffic deaths during 2014. However, an increase in estimated fatalities during the first six months of this year reveals a need to reinvigorate the fight against deadly behavior on America’s roads, the Department of Transportation’s National Highway Traffic Safety Administration announced today.
NHTSA’s Fatal Analysis Reporting System (FARS) figures for 2014 show 32,675 people died in motor vehicle crashes in 2014, a 0.1-percent decrease from the previous year. The fatality rate fell to a record-low of 1.07 deaths per 100 million vehicle miles traveled. Estimates for the first six months of 2015 show a troubling increase in the number of fatalities. The 2015 fatality estimate is up 8.1 percent from the same period last year, and the fatality rate rose by 4.4 percent. NHTSA experts cautioned that while partial-year estimates are more volatile and subject to revision, the estimated increase represents a troubling departure from a general downward trend.
NHTSA has launched a series of safety initiatives in recent months, including efforts to speed technology innovations that can improve safety and the agency’s first comprehensive effort to fight drowsy driving. The agency will hold a series of cross-cutting regional meetings across the country early next year, capped by a nationwide gathering in Washington, to gather ideas, engage new partners, and generate additional approaches to combat human behavioral issues that contribute to road deaths. These meetings will address drunk, drugged, distracted and drowsy driving; speeding; failure to use safety features such as seat belts and child seats; and new initiatives to protect vulnerable road users such as pedestrians and cyclists.
Data for 2014 from NHTSA’s Fatality Analysis Reporting System (FARS) show that while overall road deaths declined only slightly, it was the safest year on record for passenger vehicle occupants: 21,022 Americans died in vehicles in 2014, the lowest number since FARS began collecting data in 1975. While cyclist deaths also declined, the number of pedestrians killed rose by 3.1 percent from 2013.
Other trends remained stubbornly constant. Deaths in drunk driving crashes continue to represent roughly one-third of fatalities; approximately half of all vehicle occupants killed were not wearing seat belts; deaths of motorcyclists without helmets remained far higher in states without strong helmet laws; and speeding was a factor in more than one in four deaths. NHTSA research shows that in an estimated 94 percent of crashes, the critical cause is a human factor. In contrast, vehicle-related factors are the critical reason in about 2 percent of crashes.
While final 2015 numbers and a breakdown of factors in the year’s fatalities will not be available until next year, NHTSA experts noted that job growth and low fuel prices could be a factor, not only in increased driving overall, but in increased leisure driving and driving by young people, which can contribute to higher fatality rates.
Additional 2014 crash data show:
- Drunk driving crashes continue to represent roughly one-third of fatalities, resulting in 9,967 deaths in 2014.
- Nearly half (49%) of passenger vehicle occupants killed were not wearing seat belts.
- The number of motorcyclists killed was far higher in states without strong helmet laws, resulting in 1,565 lives lost in 2014.
- Cyclist deaths declined by 2.3 percent, but pedestrian deaths rose by 3.1 percent from the previous year. In 2014, there were 726 cyclists and 4,884 pedestrians killed in motor vehicle crashes.
- Distracted driving accounted for 10 percent of all crash fatalities, killing 3,179 people in 2014.
- Drowsy driving accounted for 2.6 percent of all crash fatalities; at least 846 people died in these crashes in 2014.
