variable. If run interactively it makes sure user does not change

Tools to help download, process and analyse the UK road collision data collected using the
'STATS19' form. The datasets are provided as 'CSV' files with detailed road safety information about the
circumstances of car crashes and other incidents on the roads resulting in casualties in Great Britain
from 1979 to present. Tables are available on 'colissions' with the circumstances (e.g. speed limit
of road), information about 'vehicles' involved (e.g. type of vehicle), and 'casualties' (e.g. age).
The statistics relate only to events on public roads that were reported
to the police, and subsequently recorded, using the 'STATS19' collision reporting form. See
the Department for Transport website
<https://www.data.gov.uk/dataset/cb7ae6f0-4be6-4935-9277-47e5ce24a11f/road-safety-data> for more
information on these datasets.
The package is described in a paper in the Journal of Open Source Software
(Lovelace et al. 2019) <doi:10.21105/joss.01181>.

methodological and empirical road safety research.
