The traffic information design for mitigating congestion has been studied under the decentralized traffic management. Iwase et al. focused on oscillatory phenomena called hunting in traffic flow and proposed the concept of “self-fulfilling signal” as traffic information design to suppress hunting. Ukai and Fukuda conducted laboratory experiments to examine the suppression of hunting by providing self-fulfilling signal on drivers. However, the experiments made was small and insufficient for a proper understanding of the effect of the signal. This study conducted a large-scale interactive online experiment to analyze the inhibitory effect of self-fulfilling signal on hunting. The experimental results showed that hunting was well suppressed when the diversity of traffic information based on self-fulfilling signals was large enough. The individual route choice data was further investigated to understand information compliance behavior of drivers using the mixed logit model.
