What’s Updated/Added

New module graph_utils.py:
Builds an OSM graph from layer extents (build_graph_for_layers).
Assigns travel speeds by road type and calculates travel times
(set_graph_travel_times).
Includes utility functions for unit conversion (kmh_to_mm) and default
speed profiles (DEFAULT_SPEEDS_KMH).
Algorithm nearest_fire_station
(algorithms/nearest_fire_station_algorithm.py):
Finds the nearest fire station based on shortest travel time over the
OSM graph.
New output attributes: nearest_station, distance_km,
response_time_min, station coordinates (station_x, station_y), and
automatic detection of the station name field.
Algorithm response_time_routes
(algorithms/response_time_routes_algorithm.py):
Generates linear routes on the OSM graph in three modes:
To the nearest station only,
To all stations,
To all stations within a specified time threshold.
Output attributes: object_id, station_name, distance_km,
response_time_min, object_type, route_type.
Algorithm all_stations_response
(algorithms/all_stations_response_algorithm.py):
Analyzes arrival times from multiple fire stations based on fire
incident rank (1–5), respecting a MAX_STATIONS limit.
Computes first_arrival_min, last_arrival_min, and avg_arrival_min.
Produces a list of responding stations and a coverage assessment
(response_coverage).
Uses average straight-line travel speed for preliminary
(“back-of-the-envelope”) analysis.
Provider fire_response_analysis_provider.py:
Registers all three algorithms under the “Fire Response Analysis”
group.
Specifies supported output formats for vector, raster, and tabular
results.
Reliability & UX improvements:
Automatic detection of the station name field in each algorithm.
Progress reporting during execution.
Native handling of input coordinate reference systems via on-the-fly
transformations.
Checks for osmnx availability and displays a clear, informative error
if missing.
