摘要：	Stated preference (SP) studies developed to estimate travelers value of travel time savings (VTTS) on managed lanes (ML) may underestimate the VTTS. This study investigates survey design strategies and differentiating the VTTS for ordinary and six common urgent situations faced by the travelers in an attempt to improve on VTTS estimation. An internet based survey for Katy Freeway travelers was used to collect data for this study. We used three different survey design strategies to produce surveys. We found that a random attribute level generation strategy, where the VTTS presented in the alternative was adjusted based on the answer to a previous SP question, performs better than other designs with respect to analysis of choice behavior and estimation of VTTS. We analyzed SP choices for travelers facing ordinary and six common urgent travel situations. We found that travelers value their travel time savings much more when facing most of the urgent situations. / Supplementary Notes: Sponsored by Department of Transportation, Washington, DC.
