A heterogeneous traffic model with creeping is developed as a multiclass generalization of the cell transmission model. Creeping occurs when small vehicles continue to advance in congestion even though larger vehicles have completely stopped. To capture creeping, the model is posed as a phase transition model which applies a multiclass cell transmission model in the non-creeping phase, and a classical scalar cell transmission model in the creeping phase. The discrete model with creeping is presented by considering the sending and receiving of vehicles for each vehicle class. Numerical tests are carried out to illustrate the creeping phenomenon, and a comparison with two exiting heterogeneous multiclass models is performed. The model can be used to study the evolution of traffic flow in many emerging economies, where significant creeping is observable.
