What are the different characteristics of different modes of transportation?

Different modes of transportation have their own advantages and characteristics: railway transportation has greater capacity, faster speed and lower cost, which is suitable for medium and long-distance cargo transportation; Highway transportation investment is relatively small and flexible, which can realize door-to-door transportation and is suitable for short-distance passenger and cargo transportation; Waterway transportation has the advantages of large volume, low energy consumption, low cost and low infrastructure investment, but it is slow and suitable for bulk cargo transportation. The pipeline has low cost, can be continuously transported, and is suitable for transporting fluids and other bulk goods; Aviation is fast, but the cost is high, which is suitable for medium and long-distance passenger and cargo transportation. In the world, the passenger volume and freight volume of road transportation rank first among all modes of transportation.
