The thesis deals with the Managed Lanes demand estimation problem in the state of Texas. Managed Lanes are a general type of High Occupancy Toll roads, whose lane management and operational features may be dynamically adjusted. A stated preference survey is designed in both English and Spanish to collect the required data. Each survey taker is presented with up to four scenarios. Scenarios are defined in terms of travel times in Managed Lanes versus General Purpose Lanes, as well as, the toll charged for access to the Managed Lane. Respondents were asked to choose among three modes and two lane types. The survey was primarily conducted on two different internet websites for Dallas/Fort Worth metroplex and the Houston area during summer 2006. Out of 4634 collected responses, 2026 entries were from DFW and 2562 were from Houston. Multinomial and Nested Logit models were estimated. Alternative Specific Multinomial Logit models were selected based on the overall fit and percent correct measures on the estimation and validation datasets.
