Recently, a bound for the direction of the Shanghai Pudong Airport airport line four bus in Shanghai elevated road traffic incidents of Chinese attack, hit a road maintenance vehicle and hit the guardrail. The incident caused 2 female passengers fell to the ground from the elevated, died on the spot, there are 7 people were injured in varying degrees. Cause of the incident is under further investigation. The injured have been to the nearest hospital for treatment.
Traffic safety is a hot issue, the whole society pays attention to the rotation of the guardrail, roadside traffic incidents accounted for a large share of the total number of traffic incidents. As a useful means of roadside guardrail on the highway vehicle door trouble, is closely related to its end planning and road traffic safety.
About 10 million people died in traffic incidents China every year, forming a direct economic loss of about 20000000000, in the face of this trend, it is particularly urgent to strengthen road safety, although do not rotate the highway guardrail to avoid accidents, but can greatly reduce the accident occurred when the casualties. Because sometimes the car bump may not be formed between episodes of great damage to the people, but the car and bump is extreme risk. In general, the guardrail is an integral part of the highway, on the protection of the safety of the driving force plays an inestimable role.
The main characteristics of expressway is capable of high-speed driving, in bringing lunch together also have the potential to infinite crisis, when the car speed will travel to attack the greater the rate of kinetic energy, kinetic energy is greater, so the attack emergency is very simple to dodge and attack incidents, a car at high speed into imaginary to a solid stone, the immediate suspension of car, so can not go out will transform the kinetic energy is transformed into energy will damage the car, if the stone is transformed into the rotary drum if the vehicle does not immediately stop but along the drum rotation speed decreased slowly during this period, the direct kinetic energy is converted into the rolling friction force of unloading and gradually consumed off.
The traffic safety problem as a worldwide problem, leading to more and more people's attention, China highway traffic safety guarantee work also face enormous challenge. The traffic incident is not inevitable, to achieve zero casualty current technology is unlikely, but the severity can improved highway traffic safety equipment to reduce traffic highway trouble. Safety equipment includes: safety fence, signage, markings, barrier gate, the drum rotary guardrail is currently the largest safety protection measures.
Anhui Ming exclusive double drum rotating guardrail, greatly reducing casualties, as traffic safety escort.
