The distance is mainly determined by the distance between the two vehicles at the time of performing braking and hedging actions on two conflicting vehicles; for the type of rear-end collision, the conflict distance is mainly determined by the follow-up of the two vehicles when performing the braking and hedging actions on two conflicting vehicles. Interval; For the type of cross-conflict, the conflict distance is mainly determined by the distance between the collision points of the two vehicles when the two conflict vehicles are subjected to braking and hedging. For collision type of the collision, the conflict distance is mainly determined by the conflict. The distance from the vehicle to the fixed object when the vehicle performs the braking and hedging activities; for the type of conflict itself, the conflict distance is mainly determined when the vehicle is subjected to braking and hedging on the road to the point where the traffic accident occurred on the road or to the side of the road (when traffic The distance between the accident occurred outside the road. From the perspective of preventing or reducing the hazards of traffic accidents, the longer the conflict distance, the more beneficial it is to prevent or reduce the harm of traffic accidents.
Judging from the quality of conflicting vehicles, for the two front-line vehicles, when the frontal conflict occurs, under certain other conditions, the risk to the lesser quality of the conflict is more serious; when the quality of the two conflicting vehicles, When the speed is equal, the risk caused to the two vehicles during the conflict is quite equal. When the two conflict vehicles have the same quality and different speeds, the risk to the higher speed parties during the conflict is greater. For vehicles on the road structure, etc., and its own type of conflict, under the condition that he has a certain condition, the greater the quality of conflicting vehicles, the more serious the danger caused by conflict. In addition, the level of driving skills and psychological quality also have an important impact on the induced traffic conflicts on road sections. Road traffic conflicts are closely related to road traffic safety. The analysis of the road traffic conflicts and their influencing factors aims to improve road traffic safety. Maintaining proper vehicle speed while the vehicle is in motion, the driver maintains effective attention, and early detection of abrupt and abnormal changes in the vehicle and surrounding environment is critical to preventing and avoiding the occurrence of traffic conflicts; in addition, improving the driver The driving skills and psychological qualities are also important.
Construction Aluminum Profiles
The biggest characteristic of aluminum and aluminum alloy is that its bulk density is about 1 / 3 of that of steel, while the specific strength (the ratio of strength limit to specific gravity) can reach or exceed that of structural steel. Secondly, aluminum and aluminum alloy are easy to be processed into various shapes and can adapt to various connection processes, so as to provide favorable conditions for the building structure to adopt the most economical and reasonable section form. Therefore, the use of aluminum alloy can not only greatly reduce the weight of buildings and save materials, but also reduce the workload of component transportation and installation and speed up the construction progress. This has a more significant economic effect on earthquake areas and mountainous and remote areas with inconvenient transportation. Aluminum and aluminum alloys have beautiful color, good corrosion resistance, high reflectivity to light and heat and good sound absorption performance. Various colors can be obtained by chemical and electrochemical methods. Therefore, aluminum materials are widely used in roofs, walls, doors and windows, frames, internal and external decorative plates, ceilings, suspended ceilings, handrails, indoor furniture, store containers and construction templates of industrial and civil buildings.
