15

Joint Trip Assignment

Long distance auto trips and heavy trucks are assigned first Using “All-or-Nothing” assignment

Long distance auto trips and heavy trucks PCEs are used as a ‘preload’ for short distance trip assignment

Short distance autos, medium and light trucks are assigned using the Multimodal – Multiclass Assignment (MMA) method
