Does anyone know the bus route rules in Xi 'an? How many buses are there in one place?

This is stipulated by the Ministry of Construction:

1-99: urban bus lines.

100 —— 199: urban tram lines.

No.200-No.299: Suburban Line (Urban-Suburban)

300 -399: Suburban Line (Suburban-Suburban) and Suburban Line.

400 -499: Public-private partnership route.

No.500-No.599: Shizhong Bus Line (take the local branch line).

No.600-No.699: Bus lines (such as double-decker cars and air-conditioned cars). )

No.700-No.799: China-Pakistan Special Line

800 -999: Sightseeing route.

But there is a gap in actual operation:

1. Because the city has developed rapidly in recent years, the original suburbs may become urban areas, so some road numbers have followed the previous ones.

2. Some road numbers in 2.Xi 'an are named according to the starting and ending units, such as 402 road, 6 18 road, etc. The end points were originally at 402 and 6 18, but they have moved in recent years.

3. Regarding 10 1, 104, 106, 107, their bus number should be a tram number, and 104 was changed from the original 103. Other naming reasons are unknown.

4. As for the questions about bus No.602, 604, 607, 609 and 6 12, they are all ordinary buses, but the bus number is used, because bus No.602 is the earliest double-decker bus line in Xi 'an. After the first batch of double buses were eliminated, they were replaced by ordinary buses, and the line number remained unchanged. 604 was originally an air-conditioned bus line. No.607 is the original sub-No.602, later changed to No.607, No.609 is the original 60 1 dedicated line, and later changed to No.609 .. 6 12 bus is the original 61bus, and later changed to 6 12 bus.

5. About the newly opened environmental protection 700 road. Not CMB. It uses a routing number of 700, purely for everyone to remember.
