The objective of integrating platoon dispersion with DTA is to improve the representation of flow propagation in the DTA model and enforce the first in, first out constraints. A set of new linear formulations for flow propagation that include explicit constraints on the movement of traffic in a transportation network is presented. Based on the numerical examples, it can be demonstrated that platoon dispersion is realized in an analytical DTA model by using the existing solution algorithm.
