Move characters following some mobility models

I want to make some of the background actors (humans , vehicles) in my game move following some mobility models like brownian model , random waypoint model , random Gauss-Markov model so that their change in velocity , location and acceleration over time is well-defined and communicated.

Are there any good sources I can refer or can someone please explain or guide me on this (feasibility / process /outcomes)

P.S. : I am very new to game development using Unreal but too enthusiastic for it.

Thanks in advance! :smiley:
