• Modelling Human Choice Behaviour in Agent-Based Systems
  Abstract: Over the past decade, agent-based models have become increasingly used in transportation studies. The biggest advantage of the use of agent-based models over other modeling methods is the ability to simulate the interactions between individuals in detail and, hence, to study the emergent effects that may arise from these interactions. Because of the dynamics between individuals, the formalization of behavior in an agent-based system is important. Surprisingly, this is often done in an ad-hoc way, partly due to a lack of agreed-upon frameworks. This contrasts highly with the formalization of human behavior in traditional modeling theories, such as rational choice theory and theories of bounded rationality. Ad-hoc modeling limits the comparability and transparency of agent-based applications and reduces the possibilities to apply frameworks developed for particular purposes in other work. Research in the field of transportation could benefit from a more explicit, systematic and transparent formalization of human behavior in agent-based systems and from a formalization rooted in accepted behavioral theories and frameworks. This paper provides insights into the different approaches to model human behavior, explores their formalization within agent-based systems and reviews relevant applications in agent-based systems in the field of transportation. The ultimate aim is to provide a basis for a more systematic and theoretically-sound approach to model behavior in agent-based systems.

• Are Mariner Near Misses Influencing Design?
  Abstract: In an on-going research effort by ABS,Lamar University, and vessel operators, over 18,000near-miss reports have been collected. The focus ofthis paper is on near-miss reports that included arecommended “design” change on or to the vessel andany related quality or safety management system.Limited consistency in the definition of a near missand the type of near-miss data being collected wasfound. Interestingly, it was noted that most of the nearmiss reports for this study contained some form ofrecommendation or corrective action. This review alsonoted apparent differences in vessel operator safetyprogram maturity among the companies providingnear miss data.As a result, this investigation focused on therecommended corrective actions and associatedhazard control processes. Additionally, based on thefindings of limited consistency, this paper will discusscore components for near miss reporting and for aneffective near miss management system.
