The construction of the information superhighway will enable human beings to live in an ubiquitous information network: a smooth information network will transmit a large number of images, sounds, texts, data and other information to the hands of information demanders in a timely manner; Information resources are fully exploited and utilized; Information has become the third pillar of human survival and development after material and energy. From now on, mankind will truly enter the information age, and all aspects of human social life will also undergo major changes.

China is currently in the stage of rapid economic development, to ensure the sustained growth of GDP is the focus that must be achieved, so the development of the railway has an important strategic position for the country
First, the development of high-speed railways can solve the problem of insufficient transportation capacity. For a long time, the scale and quality of China's railway network have seriously failed to meet the needs of economic and social development, especially the transportation capacity of busy trunk lines is extremely tight, not only the passenger capacity is very short, but also the transportation of goods is greatly restricted. The development of high-speed railways can realize the passenger and freight transportation of busy railway trunk lines, reduce passenger and freight interference, free up the capacity of existing lines, develop heavy-duty transportation of goods, greatly release the freight capacity of existing lines, and provide sufficient capacity guarantee for the steady and rapid development of the national economy;
Second, the development of high-speed railways can promote the development of industrialization and urbanization, and promote the coordinated development of regions and urban and rural areas. At present, China is in a period of accelerated development of industrialization and urbanization. High-speed railway plays an important role in ensuring the flow of a large number of urban population, realizing the rational layout of central cities and satellite towns, giving full play to the radiation and driving role of central cities to surrounding cities, and strengthening the "same city" effect of neighboring cities.
High-speed railway can greatly shorten the time and space distance between regions and between urban and rural areas, China's east and west, north and south will no longer be far away, and the central region will also be more accessible, which will promote the rapid flow of labor, especially talents, information and other elements between regions and urban and rural areas, drive the transfer of related industries from economically developed areas to underdeveloped areas, and enhance the "hematopoietic" function of rural economy;
Third, the development of high-speed railways is the need to build a resource-saving, environment-friendly and sustainable comprehensive transportation system. Due to the relatively lagging development of railways, the transportation of key resource strategic materials in some countries currently relies on other modes of transportation, which not only increases the cost of social transportation, but also greatly increases the consumption of energy materials such as oil. Railway transportation mode has outstanding advantages in land occupation, energy saving, environmental protection, etc., and it is of great significance to strengthen the backbone position of railway in resource materials and medium and long-distance transportation and the comparative advantages of passenger transportation in economically developed areas, which is of great significance for the realization of scientific and harmonious development of comprehensive transportation.
Railway freight transportation is one of the main modes of modern transportation, and it is also one of the two basic modes of transportation that constitute land cargo transportation. It occupies an important position in the entire transportation sector and is playing an increasingly important role.
Railway transport is less affected by climate and natural conditions, and the transport capacity and single car loading capacity is large, in the transport of regularity and low cost occupies the advantage, coupled with a variety of types of vehicles, so that it can carry almost any commodity, almost without weight and volume restrictions, and these are road and air transport modes can not be compared.

Railways in the economy of our country.
It plays an extraordinary role in construction
On the one hand, during the period of railway construction, railway construction can drive the development of steel, cement and other industries and increase the employment rate; On the other hand, after the completion of railway construction, it can improve the regional transportation situation and stimulate regional economic development. Only when the road is connected can the money be passed, the materials can be circulated, and the value can be generated only when the circulation is circulated, so as to promote the economic development of the society. For example, there are many natural resources in remote areas, and if there is no railway, they cannot be transported, and they cannot produce economic effects and play their own role.
Moreover, the railway is the main artery connecting the major economic regions and between urban and rural areas, and speeding up the construction of railway infrastructure is conducive to promoting the coordinated development of regions and urban and rural areas. In various modes of transportation, railways have obvious advantages in saving resources and protecting the environment, and accelerating the development of railways is of great significance for building a resource-saving and environment-friendly society and promoting the sustainable development of the national economy.
Railway transportation is related to the safety of people's lives and property and the quality of life, and only by accelerating the modernization of railways can we fully embody our party's people-oriented value pursuit and promote social harmony in transportation.

The country's main contribution to railway construction is to facilitate communication. The transportation capacity of railways is comparable to that of non-road transportation, and convenient and efficient transportation can not only strengthen interpersonal communication and interaction, but also promote local economic development through the convenience of logistics.

On the one hand, during construction, railway construction can drive the development of steel, cement and other industries and increase the employment rate; On the other hand, after the completion of railway construction, it can improve the regional transportation situation and stimulate regional economic development.

To put it simply, I mean what I understand:
The speed of messaging has been accelerated, and the network resources have become more powerful on average.
Theoretically speaking, it should be done according to the technical specifications for subgrade construction. However, if you can find an elevation datum point over a short distance, I think you should be more flexible in segmentation. For example, there is an elevation datum point on 0+000, and there is also a datum point near 0+980, so that the adjustment can be carried out on this segment with higher accuracy. >>>More
There are a lot of them on the Internet, so I'll take a paragraph for you. "Check the condition of the vehicle, such as the fuel gauge, tire pressure, lights, brakes, etc., but also check the spare parts, such as fault triangles, jacks, spare tires. >>>More
In order to further improve the efficiency and service level of toll roads, and facilitate the rapid travel of the masses, a plan has been formulated on issues related to the exemption of tolls for small passenger cars with 7 seats and below during major holidays. >>>More
You make it possible to copy your composition.
First, speed measurement, through the digital image processing technology analysis camera recorded by the establishment of a coordinate system according to the vehicle through the camera delineation of the field of view of the time to measure the speed, such as in the camera field of view on the road surface virtually out of two markings and calculate the actual distance, and then according to the vehicle by calculating the time of the two markings to determine the speed, the highway is relatively rare. So when you see that there is only a camera on the crossbar, don't think you can't shoot speeding. >>>More
