A study released by the Highway Loss Information Institute (HLDI), an affiliate of the Insurance coverage Institute for Highway Security (IIHS), has indicated that the heavier building of hybrid automobiles make them secure for drivers, but their quiet motors make them a hazard to pedestrians.

To most of us, this comes as an unexpected consequence of cleaner, quieter, a lot more environmentally friendly automobiles. Positive, they significantly decrease noise pollution, but a lot of pedestrians rely on their sense of hearing to detect oncoming automobiles.

The study indicated that hybrid car occupants endure fewer crash associated injuries than these in traditional automobiles, but the study located that hybrids bring about a lot more pedestrian accidents than their non-hybrid counterparts.

The study suggests that the weight of hybrids factored in the 27% reduce in bodily injuries. Batteries and other elements add to the curb weight of hybrid automobiles. A hybrid sedan can weigh 480 pounds a lot more than its traditional counterpart. Some think that hybrid drivers may perhaps not be as aggressive on the road, additional contributing to the reduced injury price. ”Because they are a lot more concerned about maximizing fuel economy and generating positive that they are obtaining each and every mile out of the gallon,” mentioned Joseph Telmo, a Toyota representative.

On the pedestrian side of factors, the danger of injury from hybrid automobiles is 20% higher than from traditional gas models. The primary explanation is the quiet electric motors. These motors are touted as a single of the positive aspects of the hybrid automobiles, but have turn into a security hazard for walkers.

”When hybrids operate in electric-only mode, pedestrians cannot hear them approaching,” mentioned Matt Moore, vice president of the Highway Loss Information Institute and an author of the report. ”So they may well step out into the roadway without having checking 1st to see what is coming.”

Congress has offered the Insurance coverage Institute for Highway Security (IIHS) 3 years to come up with a security guideline to equip hybrids and all- electric automobiles with sounds to enable defend unsuspecting pedestrians. Toyota is ahead of the game. The 2012 Toyota Camry hybrid and Prius emit a noise that increases in pitch as the car or truck comes closer.

Ford is operating to create a sound that alerts pedestrians, but is not annoying, mentioned Chad D’Arcy, a Concentrate electrical advertising and marketing manager. It sounds like a answer will quickly be located, but we can only hope that it will not be an annoyance. Possibly automakers need to just make their electric automobiles emanate a sound that mimics a typical combustion engine?
