A method, apparatus and computer program product are provided to more accurately construct a traffic model. In regards to a method, links of a second traffic model are categorized as being either observed or unobserved. A link is observed if a most likely route through a first traffic model transits over the link and includes at least a predetermined number of probe data points. Separately for an unobserved graph comprised of unobserved links and an observed graph comprised of observed links, the method determines a fastest path between common nodes that appear in each of the unobserved and observed graphs. In an instance in which the fastest path in the unobserved graph is at least as fast as the fastest path in the observed graph, a travel time penalty is added to a travel time of the unobserved link in a second traffic model, subsequent to the first traffic model.
