Determination of Bus Crowding Coefficient Based on Passenger Flow Forecasting

Table 1

Passenger standing density evaluation standards.

Service level	Comfort level	Standing-passenger density (people/m^2)	Description
A	Very Comfortable	3	Satisfy the passengers' psychological comfort requirements and the comfort space is just in contact.
B	Comfortable	5	Passengers can move slightly in the vehicle to meet body comfort requirements and the passenger's body will come into contact.
C	Generally Crowded	6	Passenger's body can maintain a standing position, and the passengers can be in contact with each other without squeezing, which can satisfy the basic space.
D	Crowded	7	Passenger's body remains squeezed and have a sense of crowding, but there is no safety issue.
E	Very Crowded	7.5	Passengers squeeze each other and feel uncomfortable. They may cause safety problems.
F	Unbearable	9	Passengers need to break through the seat area and squeeze into the seat area. It is extremely crowded and unbearable. In addition, boarding and alighting bus become difficult. It is an extreme situation.
