基于前景理论的驾驶人停车选择模型

摘要

考虑到期望效用理论的缺陷及驾驶人的有限理性,利用前景理论,建立了停车选择决策模型.通过对调查数据的回归分析,确定了停车影响因素的参照点,建立了价值函数及决策权重函数,得到了单因素的前景值.利用模糊偏好下多目标决策权重赋值方法,确定了影响因素的权重,从而建立了驾驶入的停车选择模型.%In terms of defects of expected utility theory and drivers' bounded rationality, prospect theory was used to establish a new parking choice model. Based on survey data, the reference points of factors to influence parking choice were estimated with regression analysis. The value function and weight functions of decision-making for single factor were established so that the prospect value of every factor could be acquired. The multi-objective decision-making under fuzzy preference weight assignment method was used to assign the weight of every factor to obtain the overall values of options.
