evacpath: Least-cost pedestrian evacuation modeling in R

evacpath provides tools for modeling pedestrian evacuation distance and travel time from hazard zones to safety areas using road-constrained least-cost path analysis.

Details

The package is organized as a set of modular functions. Typical workflows use prepare_tsunami_zones() to create tsunami-specific hazard and escape zones, crop_roads_to_inner_extent() and make_road_aware_escape_zone() to prevent false escape points along artificial study-area boundaries while retaining bridge and walkway corridors, find_escape_points() to identify candidate exits, make_conductance_surface() to build a slope-based conductance surface, and run_evacpath() to run the full workflow.
