How to distinguish between outer ring and inner ring

Location and scope, function and role.

1, the outer ring is usually located outside the inner ring, forming the boundary of the city center and surrounding the inner ring. The outer ring is generally a ring road or expressway, connecting various urban areas. The inner ring is located inside the outer ring, usually the main road or ring road of the city, surrounding the core area of the city.

2. The outer ring usually plays the role of connecting various regions of the city, logistics and transportation, and traffic circulation, and bears the pressure of long-distance traffic and transit traffic. The inner ring mainly serves the core area of the city and undertakes the functions of short-distance transportation, business activities and urban transportation.
