Driving is defined as a process of moving from one destination to another with the main aim to get to the destination safely. This study proposes a computational situation awareness model to assist drivers in effective performance of action based on his decision. The model incorporates cognitive factors that will influence action performance (yes/no) of the driver. To illustrate the proposed model, simulation scenarios based on overtaking maneuvers has been conducted. The experimental results show that the external factors attention and expectation have contributed to the effect on the safe and risky driving behavior and by suggestion on the driver’s action to perform the overtaken maneuvers based on his decision. Moreover, this model has been verified using an automated verification tool by checking its traces with the existing results from the literature.
