1. Road transportation: gas vehicles are mainly used. Other vehicles (such as human and animal drawn vehicles) can also be used for freight and passenger transport on the road. Highway transportation mainly undertakes short distance and small batch of goods by water. It is difficult for railway transportation to reach the area for long-distance and large-scale cargo transportation. The advantages of railway and water transportation are difficult to play. Due to the strong flexibility of road transport, in recent years, long-distance public transport has also begun to use road transport in areas with railway and waterway transport. The main advantages of highway transportation are strong flexibility, short highway construction period, less investment, easy adaptation to land, and low requirements for stops. It can be in the form of "door to door", that is, from the shipper's door to the consignee's door, without transit or repeated loading and unloading. Road transport can also be used as a means of connection between other modes of transport. The economic radius of highway transportation is generally within 200km.

2. Railway transportation: It is a way to transport passengers and goods by train. Railway transportation mainly undertakes long-distance and large-scale transportation tasks. In areas without water transportation conditions, almost all large goods depend on railways, which play an important role in trunk line transportation. The railway transportation has the advantages of high speed, small restriction by natural conditions, high transportation power and low transportation cost. The main disadvantage is poor flexibility, which can only be carried out on fixed lines. Other means of transport are required to coordinate the connection. The economic mileage of railway transportation is generally more than 200 kilometers.

3. Water transportation: This is a way to transport passengers and goods by ship.

Water transportation mainly undertakes the volume of bulk transportation and long-distance transportation, and plays an important role in trunk transportation. In inland and coastal areas, water transport is often used as a small means of transport to supplement and connect a large number of trunk lines. The main advantage of water transport is low cost, which can be transported in a low-cost, large-scale and long-distance manner. However, due to the long season, the transportation is greatly affected by the season, and the transportation speed is greatly affected by the season. There are four forms of water transport:

1) Coastal traffic: It refers to the way of transporting passengers and goods by ships through coastal channels close to the mainland. Small and medium-sized ships are generally used.

2) Sea transportation: It refers to the transportation of passengers and goods in the whole mainland countries through sea lanes. Depending on the voyage, medium-sized ships or small ships can be used.

3) Maritime transport: It is an ocean transportation form of a ship, mainly relying on large ships.

4) Inland transportation: It is a way to transport ships by land and water such as rivers, lakes and rivers. It mainly uses small and medium-sized ships.

4. Air transportation: This is a way to use aircraft or other aircraft. The cost of air transport is high. Therefore, there are two kinds of goods suitable for transportation. First, goods with high value and strong freight capacity, such as parts of valuable equipment and high-end products; Second, emergency materials, such as disaster relief materials. The main advantage of air transport is that it is fast and not restricted by terrain. It is of great significance to rely on air transport in areas that cannot be reached by trains and cars.

5. Pipeline transportation: It is a way to transport gas, liquid and powder solid through pipeline. Its conveying mode is realized by the movement of the pressure direction in the pipeline. The important difference from other transportation modes is that the pipeline equipment is fixed. Conveying liquids and gases, as well as powders and particles. Various small and short distance freight and passenger transport can be selected for freight transport. The continuous operation is safe and reliable, but the equipment investment is large, the flexibility is poor, the cost is high, the equipment requirements are high, the technical conditions are high, and it is greatly affected by the climate. With strong mobility, it can realize "door-to-door" service and is more flexible than railway transportation.
