Network reliability‐based optimal toll design

open access: yesJournal of Advanced Transportation, 2008
AbstractOptimal toll design from a network reliability point of view is addressed in this paper. Improving network reliability is proposed as a policy objective of road pricing. A reliability‐based optimal toll design model, where on the upper level network performance including travel time reliability is optimized, while on the lower level a dynamic ...
