In the planning of national land development, it is important to have a clear understanding of the regional structure. One index of regional structure is time distance (i. e., minimum traveling time). The computation of the time distance between any two cities is relatively simple. However, it is difficult to grasp visually the structure of the whole region with relation to time distance. This paper focuses on the use of time distance as an index of regional structure, and shows a new method for presenting such structure visually. This method enables us to create a graph of regional structure by treating each city as a vertex, and relative time distance between cities as the length of an edge. The author calls the graph a time-distance network. Construction of the network from any time distance data is generally difficult. In order to solve this problem, some rules are set for constructing the graph. In addition, a necessary condition for constructing the graph is also explored. Using this approach, the author analyzes the Multi-City structure of Tohoku Region in comparison with other regions.
