%description
Tools for road-constrained, least-cost pedestrian evacuation modeling. The
package provides reusable functions for preparing hazard zones, generating
road-based evacuation origin points, identifying escape/safety points,
creating slope-based conductance surfaces, calculating least-cost distance
to safety, and converting distance outputs into evacuation-time polygons.
It is designed to support workflows like tsunami evacuation modeling while
remaining adaptable to other regions and hazards. Tsunami-specific helpers
support separate land-only hazard zones, water-combined escape zones,
road-aware escape boundaries, and study-area inset cropping for quality
assurance and quality control. Methods build on Cordero et al. (2025)
