Road infrastructure is a vital aspect in transportation systems and can be severely affected by disasters. Postdisaster impact assessment is vital for the repair and reconstruction of such infrastructure, which is constrained by budget and time. This review provides a detailed analysis of prior literature on postdisaster impact assessments of road infrastructure. The related methods used in the literature were analyzed based on their classifications, such as social, environmental, and economic impacts of road failure. It was determined that although a wide range of methods have been used to assess economic impacts, there is still a lack of research measuring environmental and indirect social impacts. Prior literature has also highlighted that the use of bottom-up models to assess socioeconomic impacts is more relevant in the aftermath of a disaster. This paper presents a systematic review of the literature and guidelines for selecting the most appropriate method to assess impacts. This review aims to provide a frame of reference for researchers and government authorities involved in postdisaster impact assessment and decision making related to road infrastructure.

Natural hazards can cause a wide range of social and economic impacts both to the area directly affected by the hazards as well as to the broader community. Although community resilience is an important aspect that influences post-disaster response and recovery stages, it has not been explicitly studied by most scholars, and is rather taken to be embedded in the socio-economic landscape studied in the literature. Road structures such as bridges, culverts and flood-ways play a vital role in times of natural disasters as their functionality directly influences evacuation, rescue, recovery and reconstruction activities. In addition to the direct benefits derived from road structures, in the event of a disaster, they play a vital role in resilience by connecting individuals and communities. This paper identifies adaptation methods practiced by disaster affected communities targeted at increasing their accessibility and mobility, and analyses how such adaptation activities can minimise the negative effects brought on by the failure of road structures. The paper uses a recent case study from regional Queensland, Australia, to understand how adaptation options vary in rural areas and to explore possible methods to improve resilience of communities.
