“…Among the main contributing human errors in ship collisions that have been reported (Sotiralis et al, 2016;Ung, 2019;Weng et al, 2019;Yıldırım et al, 2019) are: errors in supervision (not keeping appropriate lookout, failure to take early actions), misinterpretation of COLREGs (IMO, 1972) and poor/lack of communication between the vessels' OONWs. Communication failures are mainly related to ambiguities, misunderstandings, unsuitable devices and absence of closed-loop communication (Boström, 2020) to provide feedback on messages. Very high frequency radio (VHF) has been the only communication medium for many years and its misuse is a contributing factor in a significant number of casualties (MCA, 2016).…”

Non-compliance with or misinterpretation of the International Regulations for Preventing Collisions at Sea (COLREGs) when assessing vessel encounters, and the lack of good communication between the vessels involved in a critical situation, are primary contributing factors in collisions. Vessels engaged in an encounter should be aware that they are part of the same scenario and situation, which can become critical. Sharing and contrasting their information about the encounter would help those responsible to take manoeuvring decisions in a consistent way. There are situations whose evaluation by the respective officers in charge of the navigational watch may diverge and lead to disagreements on the actions to be taken. If there is no proper inter-ship communication, a collision may result. This paper presents a proposal for safety communication implemented in a programmable system using common equipment (automatic identification system), and applies it to a case study of one such special situation, showing how it could help to reduce the risk of collision.

“…More communication does not necessarily lead to better communication. Effective team communication protocols that account for various situations can standardize team member's expression and reduce team communication failure (Boström, 2020). While paying attention to crew skills, the metro company must also pay attention to the communication protocol (Alavosius et al, 2017).…”

For complex metro systems to operate efficiently, effective cooperation among teams is needed. Many accidents happen due to control failure caused by team errors during cooperation. Improving the efficiency of teamwork not only focuses on the team’s organizational structure and teamwork procedure, but also stresses each workers’ state during cooperation, because personal errors or interactions errors may lead to the collaboration failure. Combining the theory of human error and the complex network theory, this paper proposes a method to identify team errors and explore the mechanisms of team error during teamwork in the metro systems. Team cooperation is decomposed into each team member’s information process and interactions among human, machines and the environment, which are connected by a collection of information flows in the task. The TICN (Teamwork Information Complex Network) is established, in which information state of individual and interactions within agents are represented by nodes, and information flows are represented by directed edges. Then, vulnerable information states causing teamwork failure are identified by analyzing the degree centrality and betweenness centrality of the complex network. In the end, the model is applied to a specific emergency. The result shows that team members need enhanced skill-based level cognitive ability, the station supervisor needs a thorough understanding of the management system and rules, the decision-maker has to make and communicate decisions concisely, and the communication equipment should be adjusted and designed according to ergonomic requirements. Based on the results, some suggestions were put forward to improve the team performance in the metro system.
