What does the main road mean?

The main road is the skeleton of the urban road network, and it is the traffic trunk road connecting the main urban areas of the city and the artery inside the city.

The main road generally has 4 or 6 motor vehicle lanes and non-motor vehicle lanes with separation zones. Generally, there is no interchange, but the method of expanding the intersection is adopted to improve the traffic capacity. Interchange can also be set up at individual intersections of main roads with particularly large traffic volume.

Main roads play the role of "communication" in urban traffic, with traffic function as the main function and service function as the supplement, and there are many vehicles that need to pass quickly.

The trunk road undertakes the transportation task of long-distance motor vehicle traffic flow across sections. Urban main roads can be landscapes, but they should not be residential, especially commercial.
