IDMM uses a memory of prior speeds to adapt the desired time headway (see https://www.researchgate.net/publication/8952918_Memory_effects_in_microscopic_traffic_models_and_wide_scattering_in_flow-density_data) whereas IDM does not. The Wiedemann Parameters - security (0.5) - estimation (0.5) The model also obeys the parameters: accel, decel (only when stopping at a fixed position) and emergencyDecel.
