Fracking operations require large numbers of vehicles, particularly in the first months of operation during well pad construction and drilling. Throughout a well's lifetime, vehicles may be needed for transport of fracking fluids, construction materials, and potentially the extracted gas itself. There is concern over what impact these vehicles may have on local infrastructure, air quality and road safety, particularly given the likely rural location of fracking operations. ReFINE research will use modelling to attempt to predict and quantify what impacts traffic may have under different scenarios.
