“Equilibrium Design of Bicycle Sharing Systems: The Case of Washington D.C.

EURO Journal of Transportation and Logistics 5 (3), 321-344.
Nair, R. and E. Miller-Hooks (2014)

Pub63An equilibrium network design model is formulated to determine
the optimal configuration of a bicycle sharing system in Washington, D.C.
Such systems involve a fleet of bicycles positioned at various stations across the
network. A user is permitted to check out a bicycle at any station and return
it to a station close to her destination. Operators of such systems need to
determine the optimal configuration that maximizes utilization. Users employ
shared-bicycles for their trips only if their travel utilities improve through
their use. An equilibrium approach results in a design that supports the flows
it attracts. The model takes the form of a bi-level, mixed-integer program that
has a non-convex feasible region. A metaheuristic solution scheme is developed
to overcome the intractability of exact solution methods for large networks.
System usage patterns and travel time improvements through the use of bicycle
sharing are estimated.
