Off-road vehicles produce chemical, physical, and biological disturbance to vegetation. To predict their disturbance for efficient management, it is very useful to model and simulate the movement of off-road vehicles. The turning angles (move directions) of moving entities are very important in modeling and simulation of their movement. The distribution of the turning angle expresses the frequency of changing moving directions. This study will investigate the turning angle distribution of off-road vehicles under different scenarios and levels. Descriptive statistics and von Mises distribution, the most common angular distribution, will be used in analysis. The results will be applied in simulation of individual- and unit-based movement simulation.
