Abstract

Tram-on-tram collisions do not tend to occur very frequently on the city and suburban light-rail networks, but when they do happen, they can be very dangerous and highly disruptive to operations. In Australia, a metropolitan tram organisation had experienced an inordinately large number of tram-on-tram collisions in recent years, many occurring in two complex locations of their network. Internal investigations revealed no significant problems with the infrastructure or with the mechanical soundness of the trams involved in the collisions, but their investigations did highlight potential human factors issues including loss of situation awareness (SA). Considerable research has shown that poor SA can lead to poor decision-making which then leads to accidents, for both the individual (Endsley, 1999) and the larger system (Salmon, et al., 2009),but very little of this research has been undertaken in the light rail context. The research described here investigated the human factors causes of tram-on-tram collisions with a particular focus on SA
