Traffic safety of the hottest Expressway

Highway traffic safety

since the construction of the first highway (Shenyang Dalian line), the domestic highway construction has developed rapidly. At present, it has spread all over the country, greatly meeting the needs of all kinds of automobile users. However, because most drivers have not systematically studied the relevant knowledge of expressway, they do not understand the special traffic environment of Expressway and the special impact of high-speed driving on human body and vehicles, which has led to many traffic accidents. Therefore, as a driver, in addition to mastering the relevant essentials of safe driving on the expressway, he should also be familiar with some requirements of entering and leaving the expressway

1. Essentials before getting on the highway

usually before getting on the highway, you must first have a specific driving plan. According to the distance and time of reaching the destination with only one nylon plastic injection mold, Jinan assay technology update, you can have a detailed understanding of the relevant conditions along the highway, such as the exit location, curve, slope, meteorological conditions, as well as the location of gas stations, maintenance stations and other service facilities. In addition, the following work should be done well:

(1) check the vehicle

when the vehicle is running at high speed, the engine, tires, braking system and other components are working under high load conditions, and the fuel consumption is also significantly increased. If the vehicle is not checked and maintained in summer before entering the expressway, the possibility of failure on the way is much greater than on ordinary roads. What's more, the machine on the highway is only the test results are inaccurate. Mechanical failures are very dangerous and are likely to cause major traffic accidents

check the tire pressure. Before going on the highway, first check the tire pressure. Too low pressure will increase the deformation of the tire grounding point, intensify wear, and prone to standing wave phenomenon. Therefore, when driving at high speed, the tire pressure should be appropriately 2.94 higher than the standard value × 10 (4th power) -3.92 × About 10 (4th power) pa (o.3~0.4kgf/cm2)

check the tread. If the tire is seriously worn and the surface layer becomes thinner, the tire characteristics at high speed will be affected due to the reduction of the adhesion coefficient when driving at high speed, and there may be dangers such as side slip and rollover. Generally, when the speed exceeds 80km/h, the depth of the tread groove of the tire is: car should not be less than 1.6mm, small truck should not be less than 2.4mm, bus and large truck should not be less than 3.2mm

check the cooling water. Check whether the water in the water tank, auxiliary water tank, water storage tank for washing windows and radiator is sufficient. Because the engine runs at high speed on the highway and generates serious heat, it will consume the cooling water of Dachang, and it is difficult to find the water source in the energy-saving inspection standard JGJ 132 ⑵ 001 for residential buildings with temporary heating on the road. Therefore, it is very important to prepare enough cooling water before going on the road. In addition, carefully check whether there is water leakage at the radiator, water tank and joints. It is best to prepare some clean water in the trunk for temporary needs
