这篇文章的重点是映射和描绘通勤区的工作旅行（通勤到工作区- CTWA）。划定这些地区的传统程序是将每个城市划分为一个单一的集水区。通勤距离和通勤流的复杂性多年来稳步增加。交通规划中的一个经典方法是绘制交通流图，其中起点和目的地用一条直线连接，从而使重叠部分可视化。然而，拟议的新的工作区划分描述了每个城市核心的二维集水区与其他集水区自然重叠。四个不同程度的概括的CTWAs，从形态到一个圆形区域，进行了讨论，并比较替代映射。
This article focuses on mapping and delineating commuting areas of work travel (commuting-to-work area - CTWA). Traditional procedures for delimiting these areas assign each municipality to a single catchment area. Commuting distances and the complexity of commuter flows have increased steadily over the years. A classical method in transport planning is a mapping of flows where origin and destination are connected with a straight line resulting in a visualisation of the overlaps. However, the proposed new commuting-to-work area delineation describes a 2-dimensional catchment area of each urban core naturally overlapping with other catchments. Four different degrees of generalisation of CTWAs, from a morphological to a circular area, are discussed and compared to alternative mappings.
