Management of Animal-Vehicle Collisions (AVC) data
Recording of the following data for any roadkill is undertaken, by providing field crews with suitable training and equipment
• Collision date, and time if known.
• Location: coordinates, road code and kilometer point.
• Species involved, sex and age class, if known.
• Any information which helps to explain AVC occurrence related to landscape (presence of rivers, nearby housing, etc.) or infrastructure features (fencing, road verges issues, garbage containers, etc.).
A cooperative procedure with other organisations recording data related to AVC is established to develop a comprehensive database which will improve knowledge of AVC hotspots, helping to define solutions. Relevant organisations include:
• Traffic police and insurance companies could provide information on injury and/or damage accidents involving large animals.
• Research centres and NGOs, among others, could provide information on small road killed animals.
DATA MANAGEMENT AND AVC MITIGATION
Undertake analyses to identify where and when hotspots occurl
Provide statistical analyses of the data collected which outlines seasonal, annual and location variations in AVC numbers.
Use a roadkill clustering method to identify hotspots where AVC occur in high frequency (e.g. KDE+ or any other which has the possibility to define a frequency threshold goal) and link it to an app/web-based system managing the AVC database.
Perform analyses for particular target species or group of species (e.g. endangered species or large animals which pose a major risk to drivers).
Use maps to visualize the location of AVC hotspots and provide data from different periods of the year.
Identify where and when AVC hotspots are occurring along road sections over time.
Identify causes and provide solutions to reduce AVC risk
Identify local factors related to landscape, infrastructure features or human activities which could influence AVC clustering involving different species, to assist in the investigation of why hotspots occur.
Define the most effective mitigation measures to be applied in hotspot areas based on causes analysed. Factors which go beyond the routine maintenance of the road require ecology expert assessment.
Undertake monitoring before and after mitigation to ensure measures have reduced AVC numbers.
Periodic data analyses should be planned according to the frequency and variation of the AVC hotspot along road sections, at least once every 5 years.
