Layer: Crossing Opportunities at Large Animal Hotspots (ID: 4)

Name: Crossing Opportunities at Large Animal Hotspots

Display Field: ROAD_NAME_NUMBER

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: The large animal-vehicle collision hotspots come from a statewide Animal-Vehicle Collisions Hotspot Analysis that was performed for FDOT in 2022. The analysis calculated average number of incidences (animal-vehicle collisions) per one mile road segment and distance from the mean to determine relative level of significance. The analysis was performed using the ArcGIS (ESRI, Inc), Getis-Ord Gi Hotspot Analysis Tool. Hotspots were placed in three tiers of relative significance (based on confidence levels): Top 1% (99%), Top 5% (95%), Top 10% (90%). Each structure contained in this data layer was evaluated in the field for suitability as a large animal wildlife crossing. We used ArcGIS Survey123 to record data collected in the field. The evaluation included assessments of site characteristics including structure dimensions, fencing, vegetation, substrate, adjacent land use/cover and signs of animal use. Detailed notes were taken in many cases. This information was used to rank the general suitability of each structure to function as a large animal wildlife crossing (categories: high, moderate, low).
