Abstract
Blowing-snow disaster damage includes road infrastructures, vehicles and road users. The
damage is caused by visibility hindrance or snow drifts or both of those phenomena that are
complicatedly interacted. To manage the blowing-snow disaster risks, drivers’ cancelling a drive
trip or road administrators’ closing roads prior to the expected disaster will be effective as the
risk avoidance measures. To timely realize in-advance risk avoidance actions, activating risk
communications among the stakeholders including meteorologists, road administrators, media
and road users will be vital as they could share the information on the disaster risk from blowing
snow. Continually improving the risk communications through the PDCA Cycle may strengthen
countermeasures that are realized by the stakeholders against blowing-snow disasters, which
will result in the enforcement of social controllability of blowing-snow disaster risks.
