为了弥补传统出行方法的不足，本文重点对传统的个人可达性指标进行补充，并结合时间转移效应和家庭内部的乘车共享行为形成敏感指数。已经开发出一种基于网络的活动分配协议，用于家庭内复杂的旅行活动决策。拟议的研究将路线、调度和乘车共享组件纳入混合模型中，该模型明确捕获家庭成员之间的交互，并集成乘车共享和时间窗口约束。根据这种方法，可以估计和汇总个人的可达性以反映家庭的可达性。先前对此类无障碍方法的研究强烈表明，所提议的扩展可用于估计不同政策选择变化的影响。这项研究的结果将有助于最先进的复杂旅行行为，并验证政策敏感的预测模型。
In an effort to compensate for the deficiencies on traditional trip based approach, this dissertation focuses on the supplement in traditional measures of individual accessibility, and the incorporation of temporal transference effects and ride sharing behavior within a household to form a sensitive index. A network-based activity assignment protocol has been developed for complex travel activity decisions within a household. The proposed research incorporates routing, scheduling, and ride-sharing components into a hybrid model that explicitly captures the interactions between household members and integrates ride-sharing, and time window constraints. Under this approach, individual accessibility can be estimated and aggregated to reflect household accessibility. Prior research on such accessibility approaches strongly suggests that the proposed extensions can be employed to estimate the impacts of changes in different policy options. Results of this research will contribute to the state-of-the-art in complex travel behavior and validate a policy-sensitive forecasting model.
