The Land Transport Authority (LTA) is responsible for the land transport system in Singapore. LTA has implemented a process known as Project Safety Review (PSR) to provide a formal and structured assessment of the safety aspects of projects from the beginning of their life cycle. The paper describes the history of the PSR process, and the formal framework, both organizational and procedural, that has been created in LTA for its implementation. This formal framework allows PSR to be fully integrated into the project lifecycle. PSR requires that Safety Submissions be prepared to demonstrate that acceptable levels of safety will be achieved. The number, timing and content of Safety Submissions depends on the nature and size of the project. A large component of each Safety Submission is normally an independent Safety Review of the project together with a response to the Safety Review from the project developer/designer. Safety Reviews are largely conducted in accordance with international guidelines. However, some innovations have been introduced. The PSR process has been extended to include other road related projects, such as bus interchanges and pedestrian overhead bridges. Procedures are also being developed to cater for more complex projects such as road tunnels. Hazard logs are used as a management tool for PSR, and allow identified hazards to be monitored until acceptable mitigation measures are implemented. A classification system has also been established to assist analysis of identified hazards. Two networked computer databases have been implemented to further facilitate management of the PSR process, and to ensure that lessons learnt from previous Safety Submissions are not lost and can be easily accessed by staff. In conclusion, a brief summary of the safety benefits achieved through the introduction of PSR is presented.
