• Abstract:
  Travel demand modeling plays a key role in the transportation system planning and evaluation process. The four-step sequential travel demand model is the most widely used technique in practice. Traffic assignment is the key step in the conventional four-step planning process. It determines the estimated traffic flow pattern in the region of interest, and hence, identifies the volumes and levels of service on the various highways/streets. The estimated performance measures are then used for strategic decision-making. The traffic assignment problem is solved by utilizing the principle of user equilibrium (UE). However, there are some key issues related to stability, consistency, and convergence of the UE assignment that trouble practitioners and planners. These problems raise questions of reliability of the performance measures that represent the assignment algorithm solution outcome.
