Directional Flow
Many public transport system handle a highly directional flow of passengers—often traveling to work to a city in the morning rush hour and away from a city in the late afternoon. To increase the passenger throughput, many systems can be reconfigured to change the direction of the optimised flow. A common example is a railway or metro station with more than two parallel escalators, where the majority of the escalators can be set to move in one direction. This gives rise to the measure of the peak-flow rather than a simple average of half of the total capacity.

Famous quotes containing the word flow:
“Along the iron veins that traverse the frame of our country, beat and flow the fiery pulses of its exertion, hotter and faster every hour. All vitality is concentrated through those throbbing arteries into the central cities; the country is passed over like a green sea by narrow bridges, and we are thrown back in continually closer crowds on the city gates.”
—John Ruskin (1819–1900)
