The methodology development of railway level crossing safety systems - South Australia case study

Railway level crossing accident is one of the major contributing factors of railway related fatalities in many countries. Even though railway level crossing accidents can be considered as a rare event, the impact is often severe. In Australia, safety issues at railway level crossing are not very serious relative to those of developing countries. However, railway level crossing accidents have continuously become a concern in railway industries in especially when it involved fatalities. This paper presents a methodological development proposed for railway level crossing safety systems and South Australia's situation is used as a testing case. Due to the complex nature of railway level crossing safety systems; Petri Nets approach will be applied in assisting the development of a meaningful evaluation model. The components of basic concept of safety engineering; engineering infrastructure, level crossing surrounding environment and human factors will also be considered in the model.
