Product Feature: Modeller
The acceleration/deceleration profiles are held in the 'acceleration-profiles file' in the directory that contains the model. These can be added to the model and assigned to vehicle types under the 'Vehicle Types' section of the 'Core Network Attributes' in Modeller. Developing a new profile per vehicle type based on environmental effects, etc would need to be based on end-users observations or calculations. These are assigned to vehicle types and would capture differences in 'load/surface', etc.
