Abstract The research presented was initiated to understand the gaps in strategic planning decision making on transport infrastructure which affect the resilience of communities during a disaster. A comprehensive literature review not only captured the outcomes of published work on this topic but also the government publications and other documents which capture the planning processes as well as transport corridor planning and traffic management. A critical analysis of literature identified major gaps in the planning process reported by researchers as well as practitioners. The list of gaps were categorized in to four key areas as land use planning, transport corridor planning, road design and other areas. Out of these land use planning and transport corridor planning were identified as major areas and were focused on for further analysis.

Analysis of the gaps in decision making associated with land use planning and development was conducted through a detailed analysis of two case studies and a questionnaire to capture expert opinion of local government officials operating in disaster-prone areas. Outcome of these was identification of two major areas where erroneous decisions are made as land use rezoning approvals and land use approvals in high-risk areas. The list of gaps were validated using triangulation of data from the four case studies (two from literature and two sourced from Victorian local government sources) and the expert opinion.

Analysis of the transport corridor planning and traffic management was conducted by the analysis of a case study area in Geelong city council using intersection analysis, traffic flow analysis using SIDRA software under normal operating conditions and also emergency evacuation conditions. Outcome of this study was consolidation of gaps in transport corridor planning which affect the disaster resilience of communities.

After consolidating the gaps in decision-making practices in the two selected areas of governance, possible decision-making frameworks were analysed to understand prioritisation of the gaps. It was observed that due to the complexity of the information required, a three tiered approach is the best where you can use a qualitative risk ranking approach, a quantitative risk ranking method or expert opinion to prioritise the gaps identified for action.

The list of validated gaps identified in this research will provide the gap between ideal case and existing case and will be a starting point to identify actions required to enhance disaster resilience of communities through enhanced transport planning.
