Traffic assignment,as the basis of research in the field of transportation,has an important role in traffic flow prediction,path selection and so on.Traditional traffic assignment model to the design of traveler travel decision-making process is relatively simple.In this paper,on the basis of existing research,on the premise of bounded rationality,focusing on the irrational factors-the traveler's own subjective emotional impact on travel choice process,explore the emotional factors and the interaction of traffic flow distribution rule.Firstly,to the existing traffic flow distribution model and its related support theory is analyzed and summarized,points out the limitations of existing research,and proposed in this paper,based on the time of the research contents and technical route.On this basis,from the perspective of the irrational factors the influence mechanism of travel choice,introducing social emotional mood changes model of optimization algorithm,to express emotions through quantitative change process,this paper expounds the applicability of the method.The introduction of emotional enriches the existing traffic assignment theory system.Secondly,based on the expected utility theory,design the decision attribute,quantifiable emotional value of the traveler and traveler behavior rules,and mood changes process based on emotions affect user traffic assignment model is constructed,through the description of traveler route choice process,analysis the influence of emotional factors on the traveler utility perception.Model better reflects the traveler's own emotions and the relationship between the travel decision-making,improve the precision of traffic demand forecast.Finally,the comprehensive analysis of traveler perception of utility,people's emotional factors and cognitive factors of travel risk,by establishing the stochastic user equilibrium model based on prospect theory,the research on the premise of limited rationality,traveler reference point to the changes in the path way,emotional outlook the influence of the process.The model is more realistic and objective to reflect the operating characteristics and the law of traffic system.In this paper,from the impact of emotional factors on traveler utility cognitive perspective,respectively,based on expected utility theory and prospect theory to analysis and modeling travel behavior,analyzed the influence of the mood to travel choice mechanism,perfect the travel of the existing model assumption,enrich the existing traffic flow distribution research perspective,provides a new theoretical basis in order to reveal the travel decision process and path selection rules.
