Paper shows that gravitational concept of human interaction as formalized by D'Arcey Harvey does not account closely enough for pattern of air passenger movement in Europe when applied to traffic forecasting because of assumption made that all populations have same generative force; more effective method is to use total air traffic rather than population in interaction formula; method is used to calculate traffic for main routes radiating from Paris for year 1960; expected and actual traffics are tabulated; use of total air traffic rather than population in interactance formula improved results; rank coefficient is 0.74 compared to 0.24 previously obtained; modifications of distance factor are proposed.
