Over-reporting vs. overreacting: Commuters’ perceptions of travel times
Highlights A real-life peak period avoidance experiment was performed with car drivers. Participants over-reported their in-vehicle commuting time by a factor of 1.5. We tested whether reporting errors were consistent with the participants’ behavior. We estimated a joint SP–RP panel latent class model. Reporting errors were a poor indicator of travel time perception in RP and SP.
Abstract In a large-scale, real-life peak avoidance experiment, we asked participants to provide estimates of their average in-vehicle travel time during their morning commute. After comparing the reported travel times with the actual corresponding travel times, we found that the average travel times were overstated by a factor of 1.5. We showed that driver- and link-specific characteristics partially explained these exaggerations. Using the stated and revealed preference data, we investigated whether the driver-specific reporting errors were consistent with the drivers’ scheduling behaviors in reality and in hypothetical choice experiments. In both cases, we found no robust evidence that drivers behave as if they misperceive travel times to a similar extent as those they misreported, thereby implying that the reported travel times did not represent the actual or perceived travel times in a truthful manner. The results of this study suggest that caution should be recommended when reported travel time data are used in an uncritical manner during transport research and when determining policy.
