What are the advantages of high-speed rail compared with traditional railways?

The main technical and economic advantages of high-speed railway have the following nine characteristics:

1, with high running speed; Speed is the technical core of high-speed railway. The dominant distance of automobile is within 200km, the dominant distance of aviation is above 1000km, and the dominant distance of high-speed train is180-1000 km when it is 350 km/h, but passengers should not only save time (dominant distance), but also consider the fare.

2. Large transport capacity;

3. Good safety performance and high comfort;

4, all-weather operation;

5. Low energy consumption;

6. occupying a province;

Bridges of high-speed railway account for a large proportion, and bridges are mainly elevated. Therefore, it is the most economical to build a high-speed railway under the condition of low per capita arable land occupation in China.

7. Low project investment;

Although the investment of high-speed railway projects is higher than that of ordinary railways, it is not higher than that of expressway.

8, little environmental pollution;

High-speed railway adopts electric traction, which eliminates waste gas pollution such as dust and smoke. The noise is 5- 10dB lower than that of expressway. According to the pollution control cost of unmanned kilometers in China, if the high-speed rail 1, expressway 3.76, aircraft 5.2 1.

9. Good welfare.

The economic and social benefits of high-speed railway are remarkable. Practice in France and Japan has proved that the return on direct investment is above 12%, and the investment can be recovered within ten years of general operation. At the same time, the social cost of high-speed railway is lower than that of expressway and civil aviation. According to research, the annual social cost saved by the construction of Beijing-Shanghai high-speed railway can reach 22.3 billion yuan, and the total amount in 6-7 years is equivalent to the total investment. In addition, the high-speed railway can also stimulate economic growth along the route and provide many employment opportunities.
