SARS-CoV-2 transmission in indoor spaces, where most infection events occur, depends on the types and duration of human interactions, among others. Understanding how these human behaviours interface with virus characteristics to drive pathogen transmission and dictate the outcomes of non-pharmaceutical interventions is important for the informed and safe use of indoor spaces. To better understand these complex interactions, we developed the Pedestrian Dynamics—Virus Spread model (PeDViS): an individual-based model that combines pedestrian behaviour models with virus spread models that incorporate direct and indirect transmission routes. We explored the relationships between virus exposure and the duration, distance, respiratory behaviour, and environment in which interactions between infected and uninfected individuals took place and compared this to benchmark ‘at risk’ interactions (1.5 metres for 15 minutes). When considering aerosol transmission, individuals adhering to distancing measures may be at risk due to build-up of airborne virus in the environment when infected individuals spend prolonged time indoors. In our restaurant case, guests seated at tables near infected individuals were at limited risk of infection but could, particularly in poorly ventilated places, experience risks that surpass that of benchmark interactions. Combining interventions that target different transmission routes can aid in accumulating impact, for instance by combining ventilation with face masks. The impact of such combined interventions depends on the relative importance of transmission routes, which is hard to disentangle and highly context dependent.@en

Rail is a cost-effective and environment friendly freight transport modality when used efficiently. Stakeholders around Dutch ports are discouraged to choose rail due to uncertain train schedules and the dispersed nature of freight flows across terminals in the port. To understand the challenges and opportunities of freight transport using rail, we used a combined approach of modelling and simulation gaming as participative research method. In addition to a simulation game, we developed a metamodel to simulate all possible choices of the players in the game. We designed and executed simulation gaming sessions with professionals and students. Within these sessions, we collected data in the form of surveys and in-game observations on the behaviour of the players. We compared and contrasted the results of the metamodel with those of the gaming sessions. The main contribution of the research is the provision of a deep insight into the challenges and opportunities offered by efficient transportation of containers using rail. The combined approach allows us to assess the effectiveness of various incentives to consolidate freight, promote intermodal transportation and to encourage the development of efficient services for rail freight transport.@en

Cities face a challenging task in reducing CO2 emissions. Multiple technical solutions on district level as well as household level are available; multiple stakeholders with different values and possibilities to intervene are involved; and their actions highly influence the performance. To get a better understanding of these complexities and to contribute to a community-based transition process towards a CO2 city, a simulation game was developed. This game, GO2Zero, represents an abstract district that is challenged to reduce the CO2 emission to zero. Multiple stakeholders take actions, observe the challenges, and deal with these challenges with the final objective a sustainable district. This paper illustrates the first sessions with this game and show that different strategies of stakeholders lead to different challenges, ways to solve these, and a variety of outcomes.@en

Transportation systems are complex yet vital infrastructures. Different stakeholders have to work together to guarantee the most efficient traffic of humans and goods. Challenges that stakeholders face in such infrastructure systems, like divergent interests and attitudes, make it hard to predict behaviour. To understand the complex systems including the behaviour of the stakeholders, it is relevant to model decision-making processes. For this reason, simulation games were developed. The present article focuses on two different case studies. Both are studies in which board games were used. After explaining each case study, a comparative section follows to give an overview about advantages and disadvantages of the use of board games in the transportation sector.@en

With more flexible and large-scale learning environments, new design requirements for games emerge. Massive Open Online Courses (MOOCs) are one of the most important innovations in the learning field. Still, it is a challenge to motivate learners and to keep them motivated in such huge learning environments. To address this challenge, we redesigned a board game targeting at an integrated view on disruption and communication management in an intermodal transportation situation. From the redesign, we have learned that an online game works better with fewer roles, requires immediate feedback, and an engaging way of challenge to keep players motivated. Our findings can inform the design of games for large groups of players in an online environment.@en
