Planning Pedestrian Flows around a Subway Station: A French Case Study of the Time-Distance Decay Functions

Pedestrian flows to and from a rapid transit line station follow distance-decay functions; an exponential model with a second-degree exponent fits well the data. Observed flows in function of the distance are indicated. The average walking distance is larger than usually assumed: eleven minutes, i.e., one kilometer. The use of the subway by each professional category follows a definite pattern.
