Multimodal Transport System Coevolution Model Based on Synergetic Theory

Table 3

Symbols instructions of multimodal transport system coevolution.

Notations	Instructions
()	The quantity demanded of subsystems (railway, road, water transport, and aviation)
()	The demand on the time differential of subsystems of railway, road, water, and aviation
()	The demand growth rate of subsystems of railway, road, water, and aviation
()	Maximum demand of subsystems of railway, road, water, and aviation
()	Transport capacity of subsystems of railway, road, water, and aviation
()	In no other system capacity under the influence, the maximum transport capacity by its own resource constraints can reach the railway, road, water, and aviation subsystems.
