详细的活动/旅行调查数据的增加，在一定程度上促进了城市进程微观模型的开发。管理和探索这些数据可能是资源密集型和耗时的。研究人员和市政规划组织越来越多地面临信息管理的挑战。本文介绍了一个利用面向对象原理设计和实现对象关系地理数据库的实验。使用统一建模语言符号和可视化建模工具指定数据模型，然后将其实现为对象关系空间数据库。由此产生的数据库作为一个信息基础，能够支持实证研究和应用开发。经验表明，一个正式的信息管理方法可以提高我们对复杂的活动/旅行数据的理解，有助于这些数据的运输研究问题的知情应用。
The development of micro level models of urban processes has partially been facilitated by increased availability of detailed activity/travel survey data. Managing and exploring these data can be resource intensive and time consuming. Researchers and municipal planning organizations increasingly face information management challenges. This paper reviews an experiment in design and implementation of an object-relational geographic database using the principles of object-orientation. A data model is specified using the Unified Modeling Language notation and a visual modeling tool, and then implemented as an object-relational spatial database. The resulting database acts as an information foundation capable of supporting empirical research and application development. The experience suggests that a formal approach to information management can enhance our understanding of complex activity/travel data contributing to informed application of these data to transportation research questions.
