![]() The procedure uses the first-order reliability method to estimate traffic interruption probabilities, based on the difference between the probability density functions (PDF) of still water depth (or waterlogging depth) and vehicle wading height. This article proposes a procedure to estimate the traffic interruption probability caused by floods in roads, considering the still water regime. In this case, the vehicle’s wading height becomes relevant. ![]() In still water, the speed flow is low and does not compromise the vehicle stability. There are few studies related to the regime of still water in the trafficability. The research of the effect of floods on vehicular circulation is mainly focused on the stability of vehicles. ![]() Floods affect road infrastructure physically and operationally, increase road user costs and road agencies cost, and eventually isolate communities.
