The theory assumes that the behavior of people in various situations, including road situations, is determined by their expectations about the consequences of their actions. That is, drivers do not act randomly, but assess the probability of reward or punishment in advance and compare it with the scale of feasibility and utility. Thus, the behavior of drivers on the road becomes determined by three factors: expectation, assistance and valence (see Theory of expectations in Chapter 2.10. Key Psychological Concepts in Work Psychology).
