View In: ArcGIS JavaScript ArcGIS Online Map Viewer ArcGIS Earth

Service Description: This raster dataset depicts the estimated time to evacuate an injured firefighter and deliver them to the nearest hospital for stabilizing medical care using ground transportation only. The estimated ground evacuation time layer is intended to provide a broad view of medical care accessibility to inform incident- and regional-level strategic risk assessment and mitigation planning. The estimated ground evacuation times account for hospital locations, driving speeds on the current road network, and off-road walking speeds influenced by topography, vegetation, slash/blowdown, and waterbodies. Evacuation times are binned into broad classes (0-1 hours, 1-2 hours, 2-4 hours, 4-6 hours, and > 6 hours) commensurate with the precision of the analysis. There are several limitations of this estimated ground evacuation time dataset that users should understand. The analysis assumes that the closest general acute care or critical access hospital will be the first stop to stabilize the patient. Incident level safety and medical planning may identify different preferred medical facilities based on their actual travel times and/or capabilities. These estimated evacuation times only account for the travel portion of an evacuation and should therefore be viewed as best-case estimates. Complicated injuries may require additional time for patient evaluation, care, packaging for transport, and/or transfer to a vehicle. Travel times are calculated under the assumptions that the litter crew can travel at the median pedestrian rate (influenced by landscape factors) and that the ambulance or other transport vehicle can travel at the designated road speed limits. Users of this dataset should be thoughtful of factors not accounted for in this analysis that could slow evacuations such as additional landscape characteristics, crew condition, or dynamic factors like weather, traffic, or road closures.
