Dallas Freeway/HOV system planning study: Year 2015. Interim research report, September 1992-August 1993

This study was sponsored by the Texas Department of Transportation (TxDOT) as part of an effort to identify a balanced transportation system for the future in the Dallas area. The system should accommodate the projected travel demand at the lowest public cost. The mission of the study is to provide an intermediate planning step between the macroscopic planning analyses performed by NCTCOG and TxDOT`s Regional Planning Office and the detailed corridor analysis performed during the design phase of a roadway improvement project. The proposed system is a set of recommendations to be considered and evaluated as part of the development of the Mobility 2010 Plan Update, the long-range transportation plan for the Dallas area. The Dallas System Planning Study was developed using a methodology that focuses on peak-hour passenger travel demand for the freeways in Dallas and surrounding counties. The study analysis differs from other planning efforts in the region by its focus on peak-hour passenger travel demands and roadway operating conditions, the use of 2015 as the design year for the facilities, and the acceptance of congestion for some alternatives to induce travel in higher-occupancy modes. The intent of the effort was to provide a system that served themore » travel needs with a reasonable and balanced level of congestion. The study methodology uses an iterative process to examine congestion and the consequent shift in mode so that these two factors are consistent for an alternative.« less
