AI Technical Summary

Technical Problem

Existing technologies for infrastructure resilience assessment suffer from problems such as oversimplification of road network status determination, lack of assessment of potential disaster-affected populations, and inaccurate assessments due to initial data errors.

Method used

By correcting infrastructure coordinate errors, a dynamic road network model is constructed and the accessibility to the service population is assessed. This includes modules for coordinate correction, dynamic road network model, and population accessibility assessment. The KD-Tree spatial index and water depth-velocity response function are used to refine the traffic impact simulation.

Benefits of technology

It improves the initialization accuracy and reliability of the model, enables refined simulation of traffic impact, and upgrades from geometric coverage to population service assessment, accurately identifying key areas with high social vulnerability.
