The no.7 bus runs every few minutes.

There will be no.7 bus in about 20 minutes.

It used to be a bus from party school to party school, bus No.9, which ran every 20 minutes. From September 9, 2020, Bus No.7 will leave Guiyang North Station for No.3 Middle School with a departure frequency of 15 minutes. The stops are: North Station, Bazitang, Mengquan School, Old Gymnasium, Cinema, Chengzhong Road, No.3 Middle School and Old Bus Station, and return to Guiyang North Station.

The bus routes are arranged as follows:

1. Follow the principle that the line covers the main passenger corridors. The setting of lines, especially trunk lines, must be consistent with the main passenger flow direction. OD of urban passenger flow needs to be obtained through residents' travel survey.

2. The line length is moderate. The line length is too long, resulting in reduced vehicle turnover. In order to ensure transportation efficiency, more vehicles need to be put in, which increases the cost. The line is too short, resulting in an increase in the number of trips and transfers, which brings inconvenience to passengers.

3. Lines at different levels should be different. Trunk lines should cover urban trunk roads as much as possible, and the nonlinear coefficient of lines should not be too large, the smaller the better. If the nonlinear coefficient is too large, it is best to control it at1-1.5.

Bus routes are planned according to the urban development of bus companies and the basic needs of citizens. Whether to add new bus lines is decided by the relevant departments. Mainly for the people's travel needs to change and plan.
