Re: A New VDF Formula: Thank you for bringing up the capacity constraints and various issues in the context of volume delay functions and static traffic assignment (STA)! We would like to highlight that the primary goal of dynamic traffic assignment (DTA) is to lift the limitations of STA by incorporating time-dependent traffic flow variations. The concept of a "discontinuous BPR equation" can indeed offer significant benefits… https://tmip.zephyrtransport.org/scripts/wa-ZEPHYRTRANS.exe?A2=TMIP%3B30084294.2404&utm_source=dlvr.it #tmip
