Before revision:  With 870 million trips of over 50k drivers in New York City, we verify this equilibrium in space and time, estimate an empirical constitutive relation  , and examine the learning process at individual and collective levels.
After revision:  With 870 million trips of over 50k drivers in New York City, we show that the equilibrium well explains the spatiotemporal patterns of driver search behavior, and estimate an empirical constitutive relation , and examine the learning process at individual and collective levels.
