Abstract

The relationships among actual commuting travel time and its variation, individual commuters'cognition of travel time and its uncertainty, and safety margin are examined in this study.The most important finding is that the cognition of uncertainty on travel time, as expressed by the difference between the maximum and minimum travel times that experienced by daily commuting has little to do with the variance of reported travel times.The study results suggest that the assumption that objective variation in travel time will represent the traveler's cognition of uncertainty may be entirely erroneous, and the individual's cognition of the uncertainty of travel time must be investigated more closel
