基于有限理性的弹性需求随机用户均衡交通分配模型
Stochastic user equilibrium model with elastic demand based on bounded rationality
摘要
Abstract
In order to simultaneously take traffic network' s randomness and travelers * perception error into account, formulated a stochastic user equilibrium model with elastic demand based on bounded rationality framework and cumulative prospect theory. Then presented an equivalent variational inequality, followed by an algorithm and a numerical example to test it. Depicted travelers' cognition and psychological features by means of parameter sensitivity analysis. The results indicate that travel demands and network equilibrium significantly depend on reference point, and travel demands will become lager when travelers are more satisfied with network traffic condition, while it will become fewer when travelers are more familiar with it. The model and algorithm can help to deepen the understanding of travel behavior, improve the theoretic assumptions and a-daptability of traditional traffic assignment model, and demonstrate actual traffic flow pattern more accurately.关键词
