DescriptionFlood warnings are a means of risk communication that alerts the public to potential floods. The purpose of this study was to investigate factors that affected drivers’ understanding and actions given a flood presented through a mobile navigation application. We examined the effects of time pressure and type of flood information on the planned actions of the participants. Participants were asked about their planned actions given one type of flood information (flood, no flood, flood of 2 inches, or flood of 4 inches) in a driving scenario either with or without time pressure. Our results indicated significant differences in participants’ behaviors across the different flood information types, as well as a trend in the difference between the two time-pressure conditions. These results suggest that displaying the flood information is helpful to promote drivers’ safe decisions to avoid the potentially flooded roadway, although detailed information may not always help.
