本研究提出了一个联合过程-结果模型，其中所做的选择取决于每个受访者在评估每个选择定义中包装的属性时所采用的规则。提出了一种联合模型，并估计了两组基于面板的混合logit模型，其中一组忽略属性处理规则，另一组明确考虑规则。利用对未标记的时间和成本属性包的通勤汽车旅行研究的数据，在各种流程规则下确定了为节省旅行时间而支付分配的意愿。主要发现是，不考虑流程规则往往会导致统计上更高的旅行时间节省值的平均估计。有关相关摘要，请参阅ITRD E145999
This study proposes a joint process-outcome model in which the choices made are conditioned on the rules adopted by each respondent in assessing the attributes packaged in the definition of each alternative. A joint model is proposed and two sets of panel-based mixed logit models are estimated - one set in which the attribute processing rules are ignored and one set in which the rules are explicitly accounted for. Using data from a commuter car trip study of unlabelled packages of times and cost attributes, willingness to pay distributions for travel time savings are identified under the various process rules. The main finding is that failing to account for the process rules tends to result in statistically higher mean estimates of values of travel time savings. For the covering abstract see ITRD E145999
