Trip-based models are no longer adequate for some of the more complex questions. They fail to account for time of day sensitivity, dynamic congestion effects, variable pricing and tolls, and the reliability of both highways and transit. Existing activity/tour-based models lack the enhanced temporal element provided by a more dynamic, activity-based microsimulation. DASH is the next-generation model being developed by the Metro Research Center.
