Emotion modeling of the driver based on fuzzy logic

Different waiting time at the intersection and different road alignments can evoke different emotions of the driver. Emotional space of the driver is established in the paper. The emotional space consists of four factors, "happy", "angry", "relief", and "nervous". Suppose that the waiting time only cause the change in the direction of vertical axis on the emotional space and the horizontal radius of road only cause the change in the direction of horizontal axis on the emotional space. Emotion model of the driver is proposed based on fuzzy logic. The simulation example proves the feasibility of the proposed model. The results show that different waiting time and different road radius can evoke different emotions and the emotion of drivers should be considered when the signal timing is calculated at the intersection in order to avoid traffic accidents because the strong emotion states, e.g. angry, have potential to endanger driving safety.
