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) <doi:10.1007/s44367-025-00018-y>, Lewis (2021) <doi:10.1007/s10816-021-09522-w>, and Joseph Lewis's 'leastcostpath' package (2023) <https://CRAN.R-project.org/package=leastcostpath>.
