基于SPSS的终端区交通流态势评估

空中交通管理工作的实施必须以准确掌握各航线运行状况及其发展趋势为基础和前提。对终端区交通流的运行态势进行评估，即是对交通流实时运行状态及发展趋势进行分析。对终端区空中交通流进行现状评估，确定各个交通流参数的时序分布，评价终端区交通流运行状态。借助SPSS统计软件，剖析参数变量之间存在的关系，以线性回归模型为基础模型，了解变量之间如何相互影响，获取终端区流量出现拥塞的时段，反映终端区交通流特性。

Traffic Situation Assessment in Airport Terminal Area Based on Data Analysis of SPSS

Implementation air traffic management must be based on accurate knowledge of routes opera-tional state and development trend. Assessing traffic flow situation of terminal area is to analysis real-time status and trends of terminal area traffic flow. First this paper studies the present situation of air traf-fic flow at terminal area. That is to determine the timing distribution of each traffic flow parameters and then evaluate traffic flow state of terminal area. And then the paper analyses the relationship between the parameter variables by Linear Regression Model at SPSS platform. Eventually the results reveal how the variables affect each other, acquiring the terminal area traffic congestion periods, reflecting the terminal area traffic flow characteristics.
