| dc.description.abstract | The use of managed lanes to control and maximize volume on freeways is increasing. One way of encouraging more managed lane use is through the implementation of incentives. In the Dallas-Fort Worth area, a managed lane was planned for opening on I-30 (Tom Landry freeway) and incentives were planned to be offered. Because the managed lanes were not yet open and the incentives were hypothetical, a stated preference survey was used to gauge the impact of the incentives on traveler behavior.
The stated preference survey was developed through the online application Limesurvey. The stated preference questions were designed using Db-efficient and random adaptive designs. The incentives were chosen by looking at other programs around the country and through discussion with transportation experts. Once ready, the survey was administered online to travelers in the area and a total of 898 usable responses were gathered. From the responses, a mixed-logit model was developed to describe and predict traveler behavior. From the model, elasticities were calculated to predict the impact of the incentives on mode choice. Overall, the impact of incentives varied among specific incentives, with some having a modest effect while others were less impactful. | en |
