Losses Analysis#
🚧 What happens when infrastructure is disrupted by hazards?#
The Losses module in RA2CE estimates the economic (indirect) losses caused by service disruptions to infrastructure during hazard events.
While the Damages module answers “How much does it cost to repair my infrastructure?”, the Losses module answers “What is the economic impact when my infrastructure cannot function?”.
This includes, for example:
Extra travel time due to blocked or slowed road segments.
Detour and rerouting costs.
Productivity and accessibility losses.
Wider socio-economic impacts of reduced service levels.
Types of Loss Analysis#
RA2CE currently supports only one type of losses workflow:
Criticiality based losses This is the economic losses due to disruption of road segments, based on the criticality of each link in the network (see details in the Criticality analysis).
Direct vs Indirect Impacts#
RA2CE distinguishes between damages and losses:
Damages |
Losses |
|---|---|
Physical repair/rebuild costs (in €) |
Economic cost of disruption (in €) |
Based on damage curves |
Based on loss functions and Value of Time |
Example: Cost to repair a flooded bridge |
Example: Extra cost from 1h travel delay for 10,000 commuters |
Both are essential in risk assessment: - Damages reflect how much money is needed to repair/replace assets. - Losses reflect the broader economic cost of losing access to those assets.
