“…Taking into account the above factors, we run the agent-based simulation, following a similar procedure to that in 3 , 36 – 38 . The numerical results are obtained by taking an average over 100 independent episodes while changing the vaccine efficacy ( or ) and detecting errors ( or or ) within the range from 0 up to 1.…”

“…The ongoing Covid-19 pandemic has already caused grave catastrophes to the global public health and is continuing to do so. The near past has experienced outbreaks of several infectious diseases among which influenza is the most circulated one that recurrently appears with new strains 3 . It is much needed for policymakers to comprehend the spreading trends as well as possible consequences of the disease so that they can undertake a better plan to control the disease diffusion.…”

Vaccination, if available, is the best preventive measure against infectious diseases. It is, however, needed to prudently design vaccination strategies to successfully mitigate the disease spreading, especially in a time when vaccine scarcity is inevitable. Here we investigate a vaccination strategy on a scale-free network where susceptible individuals, who have social connections with infected people, are being detected and given vaccination before having any physical contact with the infected one. Nevertheless, detecting susceptible (also infected ones) may not be perfect due to the lack of information. Also, vaccines do not confer perfect immunity in reality. We incorporate these pragmatic hindrances in our analysis. We find that if vaccines are highly efficacious, and the detecting error is low, then it is possible to confine the disease spreading—by administering a less amount of vaccination—within a short period. In a situation where tracing susceptible seems difficult, then expanding the range for vaccination targets can be socially advantageous only if vaccines are effective enough. Our analysis further reveals that a more frequent screening for vaccination can reduce the effect of detecting errors. In the end, we present a link percolation-based analytic method to approximate the results of our simulation.

“…Agents are connected via links. Throughout this study, according to our previous MAS studies [ 13 , 14 ], we presumed N = 10 4 (except for three-dimensional (3D) regular graph of which population is presumed N = 9, 261) as acceptably enough to avoid the effect of finite domain size. The underlying network demonstrates physical contacts among individuals.…”

“…The MAS approach accounting underlying network effect, which can also capture various realistic scenarios inevitably brought by stochastic components, could be extended to more practical applications than simple epidemiological analysis. For instance, the so-called vaccination game [12] , [13] , [14] , where disease spreading dynamics and human decision dynamics on whether or not committing a vaccination could be mutually dovetailed. The agent-based simulation on networks delivers stochastic outcomes using a robust statistical procedure which may not be tractable in analytic procedures.…”

“…In the studies of travel mode choice, researchers have conducted a lot of studies to investigate the effects of free tickets [26], residential relocation [27], life events [28], spatial context [22], environmental attitude [16], additional incentives [29], and traffic information [11] on travelers' daily mode choice habitual behaviors. Nevertheless, one is forced to recognize that traffic information is the most pervasive.…”

Motivated by the conflict between travelers’ habitual choice behavior and traffic information search behavior, in this paper, a behavioral experiment under different types of traffic information (i.e., per-trip traffic information and en-route traffic information) was designed to obtain data regarding car commuters’ daily route choices. Based on the observed data, participants’ route choices, habit strength, response time, and information search behaviors were analyzed. It is concluded that, in the beginning, the traffic information had a great influence on the habit participants’ route choices, let them think more, and made most of them switch from habit route to the best route (as recommended by traffic information); however, as time went on, the impact of traffic information declined, and several features of habits, such as automatically responding and repeated behavior, would reappear in some participants’ decision-making. Meanwhile, the different way of traffic information search behaviors (i.e., in active performance or in passive reception) could cause different information compliance ratios. These results would help to understand the interrelationship between car commuters’ daily route choice behaviors and traffic information search behaviors in short-term and in long-term, respectively, and provide an interesting starting point for the development of practical traffic information issuing strategies to enhance the impact of traffic information to alleviate traffic congestion during morning commuting.
