The policy of the TA seems to be that it is more important to stuff bodies into a car rather than guarantee seating.The goal should be increasing the number of passengers per hour. That includes dwell time, among other parameters. If there are no defined corridors from car interiors to the doors, increased dwell time will negate any body count increase. standing passengers take up less room than seated passengers. Not as much as you may think. There are academic studies that have studied this. Many of the conclusions are contained in the National Academies' Transportation Research Board's "Transit Capacity and Quality of Service Manual." Here are some of the space requirements: Tight double seat: 3.8 sq ft Transverse seating: 5.4 sq ft Longitudinal seating: 4.3 sq ft Standing holding on to stanchion: 3.5 - 4.0 sq ft Standing with daypack: 3.8 - 4.2 sq ft Standing with briefcase, computer bag: 3.4 - 4.1 sq ft Standing: 2.2 - 2.6 sq ft Required dwell time depends on the amount of space taken up by standees. Here's the characterization of dwell time vs. area allotted per standee: 4.3 - 5.3 sq ft: Standing load without body contact; Standees have similar amount of personal space as seated passengers; Reasonably easy circulation within vehicle 3.2 - 4.2 sq ft: Occasional body contact; Standees have less space than seated passengers; Provides a balance between passenger comfort and capacity; Moving to and from doorways requires some effort, which may increase dwell time 2.2 - 3.1 sq ft: Approaching uncomfortable conditions for North Americans; Frequent body contact and inconvenience with packages and briefcases; Maximum schedule load for design; Moving to and from doorways extremely difficult, increasing dwell time; Passengers waiting to board may try to shift to a door in a less-crowded section of the vehicle, increasing dwell time < 2.1 sq ft: Crush loading conditions; Moving to and from doorways extremely difficult, increasing dwell time; Passengers waiting to board may try to shift to a door in a less-crowded section of the vehicle, increasing dwell time; Passengers waiting to board may choose to wait for the next vehicle, increasing platform crowding |
