Automatic collection of safety related road and roadside data

In order to address risk, it is important to have up-to-date information on the state of a road
network, including both road and roadside elements. Accurate collection of this information can
be time consuming, and the task often involves subjective assessment of risk. This paper
explores current technologies that are available for the automatic collection and processing of
safety related road and roadside data as well as highlighting the results from a trial to collect
information on roadside hazards.
