Convergence of fixed-point algorithms for elastic demand dynamic user equilibrium
In this paper the authors present sufficient conditions for convergence of projection and fixed-point algorithms used to compute dynamic user equilibrium with elastic travel demand (E-DUE). The assumption of strongly monotone increasing path delay operators is not needed. In its place, the authors assume path delay operators are merely weakly monotone increasing, a property assured by Lipschitz continuity, while inverse demand functions are strongly monotone decreasing. Lipschitz continuity of path delay is a very mild regularity condition. As such, nonmonotone delay operators may be weakly monotone increasing and satisfy the authors' convergence criteria, provided inverse demand functions are strongly monotone decreasing. The authors illustrate convergence for nonmonotone path delays via a numerical example.
