项目摘要

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.

为提高城际交通设施规划对取消、延误风险的责任，特别是非都市区的机场，主要采用汽车作为通行措施，近三年进行了以下研究： 1．测量进入机场路线的汽车流量：为了在时间维度上掌握机场用户的行为，通过便携式流量计数器测量了大分机场、仙台机场和广岛机场周围的汽车流量，其中还包括航班取消或延误的情况。2．取消或延误造成的行为变化分析：对上述测量的交通数据应用独立成分分析方法，掌握广岛因取消和延误造成的一些典型的行为变化。 3．航班取消和延误预知信息：通过交通流量数据计算出平均到达机场时间，结合出行始发地的地理分布，估算出航班取消和延误预知信息所需的时间。 4．航站楼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规划过程的延误，典型的设施规划过程根据预先确定的唯一交通量被划分为子规划过程，基于在不延误、不取消的基础上。5。改进计划流程，旨在风险响应：我们提出了一种新的计划流程，增加了绩效检查流程，以防取消或严重延误。对历史飞行时间数据应用独立分量分析方法，以提取几种典型的延误模式。
