Second, although traveling has become more convenie

nt for Chinese people because of the rapid development of high-speed trains and the civil aviation industry, the transfer

from one mode of transport to another can still be troublesome at times. For instance, some high-speed train stati

ons have been built far away from the cities they serve, dragging down travel efficiency.

And third, some practices-such as free highway passage-may aggravate the conflict between supply and demand.

To solve these problems, which could worsen during holidays, synchronized planning and cooperation of multiple departmen

ts are required. To cope with holiday traffic, the authorities should also promote smart transportation and use a

dvanced technologies including artificial intelligence and big data to improve travel efficiency.
