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.
regards,
Jakob
