THE INFORMATIONAL ROLE OF PEAK-LOAD EXPRESSWAY TOLLS UNDER INCOMPLETE INFORMATION ENVIRONMENT

As a basic means to realize efficient traffic assignment, congestion pricing has attracted public attention in developed countries. This paper presents a scheme for variable tolls for expressways to reduce undesirable route choices under uncertainty. The variable tolls, which are state-dependently differentiated in response to traffic conditions of road networks, can convey information about traffic conditions to drivers. Even though traffic conditions are only partially revealed through variable tolls, they suffice to decrease the risks that are faced by drivers. This paper discusses the informational role that variable toll schemes play an important role in influencing drivers' route choices in a decentralized manner. Furthermore, the authors investigate a normative model to design a variable toll scheme that can maximize the drivers' social welfare. (A) For the covering abstract see IRRD E102946.
