Proposal of new traffic signal system using emotional algorithm

This paper proposes the new traffic signal system, which optimizes the traffic flow by estimation of the driver's mind. The proposed traffic signal system applies the emotional algorithm to determine its performance. The emotional algorithm estimates the emotional value based on the emotional functions, which are defined on the emotional space. The emotional space consists of four factors, "happy," "relief," "afraid" and "angry"; it provides the emotional states of the system by the value on it. The emotional function evaluates and imitates the state of driver's mind and aims at the system not to inflict the psychological stress to the driver. This report proposes the principal architecture of the emotional algorithm and the traffic signal system using it. The numerical simulations show the effectiveness of the proposed emotional algorithm and the applied system.
