Previously, Akamatsu et al. proposed "tradable bottleneck permits" as a new transportation demand management scheme and proved the efficiency thereof for a general network. To implement such a scheme, we propose a multi-agent system for general transportation networks. The aim of this system is to achieve a socially optimal state in which the total transportation cost is minimized by the decentralized behaviour of agents. As a concrete step in designing the proposed system, we first define the micro behaviour of the agents. We also assume that the trading markets for bottleneck permits are described by a tâtonnement process. We then derive day-to-day dynamics of aggregated traffic flows and permit prices. By analyzing the macro dynamics, we prove that the mean dynamics of the aggregated variables (flows and permit prices) converge to a socially optimal state.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
