Intercity transport facility planning responsive to cancellation and delay risks

为提高城际交通设施规划对取消和延误风险的应对能力，特别是以机动车通行措施为主的非大都市地区的机场，在这三年中开展了以下研究。测量进入机场路线上的汽车交通流量：为了掌握机场使用者在时间维度上的行为，使用便携式交通计数器测量大分、仙台和广岛机场周围的汽车交通流量，包括航班取消或延误的情况。取消或延误导致的行为变化分析：对上述测量的交通数据进行独立成分分析，掌握广岛因取消和延误导致的一些典型行为变化。航班取消延误预告信息：通过交通流量数据计算到机场的平均到达时间，并考虑出行起点的地理分布，估计航班取消延误预告信息所需的时间。航站楼设施规划中利益相关者之间的冲突：为了避免因利益相关者之间的冲突而导致规划过程的延误，将典型的设施规划过程划分为基于预先确定的唯一交通量、基于无延误、无取消的子规划过程。改进计划流程以应对风险：我们提出了一种新的计划流程，在取消或严重延误的情况下增加了绩效检查流程。独立自主。将分量分析方法应用于历史航班时刻数据，提取出几种典型的延误模式。

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 f pre-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. Independent. Component Analysis method was applied to historical flight time data, in order to pick up several typical delay patterns.
