Development of a Personal Computer System for Integrating Land-use, Transport and Environmental Planning and Analysis

为了制定一个综合考虑土地利用、交通和环境问题的大都市综合规划，我们需要一个综合的计算机系统，以支持评估综合各项政策措施的效果。然而，现有的计算机系统已经为特定的目的而开发，并在不同类型的平台上工作。因此，它们几乎不能与平台上的其他操作系统兼容。另一方面，Windows作为个人电脑的操作系统平台，基本上为我们提供了一个开发应用系统的环境，而不需要考虑兼容性问题。在Windows上，我们可以标准化以前只能在特定操作系统上运行的应用程序系统。在本研究中，我们提出了一个基于Windows的综合分析系统的概念，并实际开发了一个与其他系统兼容的计算机系统。该系统是通过改进RURBAN开发的，RURBAN是由首席研究员开发的，用于支持土地利用和交通之间关系的分析，这是一个可操作的系统，可用于实际的城市规划。在此基础上，提出了一个由两个层次组成的土地利用模型，其中上层是一般土地利用模型，下层是地块层面的分布模型。利用该模型，我们可以基于详细的地理信息来分析物理模式。我们开发了更新系统，并将其应用于仙台，我们通过分析实际的土地使用模式，考虑仙台详细的土地使用法规和交通条件，来确认这些系统的可用性。

To make a comprehensive plan for a metropolis considering all of land use, transport and environmental problems, we need an integrated computer system which can support to estimate the effects of combining individual policy measures. However, existing computer systems have been developed for particular purposes and work on different types of platform. Therefore, they can scarcely work compatibly with other operation systems of platform. On the other hand, Windows, which is a platfrom of operation system for personal computers, basically provides us with the environment on which we can develop an application system without compatiblity concerns. On Windows, we can standardize application systems which formerly worked only on particular operation systems.In the present study, we propose a concept of a comprehensive analysis system on Windows and practically develop a computer system that is compatible with others. This system is developed by improving RURBAN which was already developed by the head investigator for supporting the analysis of relationship between land uses and transport, and that is an operative system which can be used for actual city planning. Furthermore, we propose a land use model composed of two levels that in the higher level is an usual land use model and in the lower level is a distribution model at the level of blocks and lots. By using this model, we can analyze physical patterns based on detailed geographical information. We develop renewal syastems and apply them to Sendai, and we confirm the availability of these systems by analyzing actual land use patterns considering detailed land use regulations and transport conditions in Sendai.
