Evaluation of eutrophication control function of shallow sea area

为了提高城际交通设施规划对取消和延误风险的责任，特别是在非都市地区的机场，以汽车为主要的通道措施，这三年进行了以下研究：1。测量进入机场路线上的汽车交通流量：为了在时间维度上掌握机场用户的行为，采用便携式流量计数器测量大分机场、仙台机场和广岛机场周围的汽车交通流量，也包括航班取消或延误的情况。2 .取消或延迟导致的行为变化分析：将独立分量分析方法应用于上述测量的交通数据，把握广岛机场由于取消和延迟导致的一些典型的行为变化。3 .航班取消和延误的预信息：通过交通流数据计算出的平均到达机场时间，以及出发地的地理分布来估计航班取消和延误预信息所需的时间。码头设施规划中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迟，典型的设施规划过程以预先确定的唯一交通量为基础，以不延迟、不取消为基础，分为子规划过程。改进计划流程，使其具有风险响应性：我们提出了一个新的计划流程，在取消或严重延迟的情况下增加了性能检查流程。将独立分量分析方法应用于历史飞行时间数据，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 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.
