In order to improve the responsibility of inter-city transport facility plan to cancellation and delay risks, especially airports in non metropolitan area, where automobiles are mainly used for access measure, the following researches were conducted in these three years.1. Measuring automobile traffic flows on routes entering airport: To grasp the behavior of airport users in time dimension, automobile traffic flows around Oita, Sendai and Hiroshima Airports were measured by portable traffic counters, covering also the case of cancellation or delays of flights.2. Analysis of behavioral changes by cancellation or delay: Independent Component Analysis method was applied to the above measured traffic data and grasp some typical change of behavior due to cancellation and delays at Hiroshima.3. pre-information of the flight cancellation and delay: Average arrival time to the airport calculated through the traffic flow data, and geographical distribution of trip origins are considered to estimate the required timing fpre-information of flight cancellation and delay.4. Conflicts among the stakeholders of terminal facility planning: In order to avoid the delay of planning process due to the conflicts among the stakeholders, a typical facility planning process is divided into sub-planning process based on the pre-determined unique quantity of traffic, based on non-delay, non-cancellation basis.5. Improvement of planning process aiming to be risk-responsive: We proposed a new process of planning by adding performance check process in case of cancellation or severe delays. Inddependent Component Analysis method was applied to historical flight time data, in order to pick up several typical delay patterns.

为了提高城市间运输设施的责任，计划取消风险和延迟风险，尤其是在非大都市地区的机场（主要用于访问措施），在这三年中进行了以下研究。1。测量进入机场路线上的汽车交通流量：为了掌握时间维度的机场用户的行为，通过便携式交通柜台衡量了OITA，仙台和广岛机场周围的汽车交通流量，还涵盖了取消或延误的情况。2。通过取消或延迟对行为变化的分析：将独立的组件分析方法应用于上述测量的流量数据，并掌握了由于取消和延迟而在广岛上延迟引起的一些典型行为变化。3。取消飞行和延迟的预先信息：通过交通流数据计算的平均到达机场的到达时间，并考虑了旅行起源的地理分布来估计飞行取消和延迟的所需时机fpre fpre fpre。4。终端设施规划的利益相关者之间的冲突：为了避免由于利益相关者之间的冲突而导致计划过程的延迟，典型的设施计划过程被基于基于预定的唯一流量的子规划过程，基于非延迟，非竞争基础的交通数量。5。计划过程的改进旨在具有风险响应性：我们提出了一个新的计划过程，以添加绩效检查过程，以免取消或严重延迟。为了拾取几种典型的延迟模式，将Indectiendent的组件分析方法应用于历史飞行时间数据。
