Project Description:
Cities, public asset owners and citizens currently struggle to keep bridges and quay walls, often long passed their (technical) end of service life, in adequate condition and open for traffic. Asset owners urgently need reliable and transparent knowledge and tools to support decisions on maintenance prioritisation and potential lifetime extension. LiveQuay will provide an integrated assessment of the safety and performance of bridges and quay walls by designing a decision support platform that will be interactive and based on values from stakeholders. However, particularly in the urban context, the utility of information from monitoring data relates to the risk perception of different stakeholders (e.g. owners, users, and citizens). Risk perception is an individual’s assessment of the uncertainty related to the alternatives in a specific decision situation. The acceptance and support of and the decision on intervention measures will depend on whether these stakeholders perceive the measures as necessary to ensure the functionality of quay walls and bridges or to reduce their risk of failure. The utility of information obtained from monitoring systems will emerge from the stakeholders’ perception of the risk represented by this information. Here, the way of representing the risk will influence its perception. Cognitive biases can lead, for example, to the underweighting of risk when a decision maker perceives an outcome as certain while, in fact, it is uncertain (pseudo-certainty effect). As partner in this project, we will investigate the manner of informing and consulting stakeholders about monitoring activities considering the effects of monitoring results on the risk perception of stakeholders.
