The car design save your life when accidents

 - Confront cars in a traffic collision, pedestrians or motorcyclists will somewhat preserve life through the design below.Statistics show that on average almost two-thirds of the 1.2 million people die every year due to road traffic crashes worldwide are pedestrians. Although this problem is extremely serious, most efforts to reduce pedestrian fatalities focused on education and traffic regulations.
Engineers have begun using design principles have been proven successful in protecting the occupants in the vehicle to develop ideas to reduce pedestrian injury in the event of a collision. The designers spent decades regarding the suspension, hood, and windshield pillars were re-constructed to absorb more light energy that does not affect the integrity of the structure.
Designing for Pedestrian Safety offers hope 5000 will limit the number of people killed, 7000 injured every year in the United States.
Unlike the more difficult to identify other techniques, designed for pedestrian safety directly affects exterior styling of a car and sometimes in combination with other features.
Low and sloping hood
For example, many current models usually have low front hood to help the driver to observe the faster and can take effect in situations collide with pedestrians. In this case, the human body is pushed to the right instead of working on the car and was ran over. The pickup and SUV models are often less effective in this type of safety testing by the design of the front bumper and hood last great noble cause great impact to pedestrians.
Cars today are designed to increase aerodynamic efficiency for longer distance criteria, less fuel. The resulting fuel is not good minimum space between the outer shell and the hardware components inside the structure.
Serious head injury or death usually occurs by right under the engine hood is a hard and heavy. Improvements in design based on the principle of mitigation mechanics of the human body on the hood. By increasing the distance between the plastic hood and inside the engine, open space like an air cushion to help mitigate the impact on the head when the accident occurred. Experiment with simulation mannequins evolution of active legs, chest and shoulder blades when the collision occurred with a car. Using feedback from this trial, 2001 Honda Civic and many Volvo models are designed with 7.6 cm gap between the hood and engine block.
Design details easily damaged exterior
It may sound paradoxical, but it helps keep the road network if the accident occurred. Remove the decorative details on the hood can be caught in the pass, mirrors automatically fold back towards the door handles and even a well designed "negative" on the door to protect both the when another collision.
Another challenge in the study of pedestrian safety, which is the exterior details such as windscreen wipers have easily destroyed under sudden impact collision to reduce the damage while ensuring the ability works well.
Collision warning devices and safety systems
Obviously, it is a difficult task when creating a safe vehicle occupants and the outside. Development of technology-based equipment warning criteria for the control of the interior cavity is a necessity, but these devices only work to prevent accidents. Still need a solution needed to minimize the severity of the collision happened suddenly. Tests such as air bags, rubber or the lighter weight and are the starting point for a comprehensive safety technology.
