Managing the Chicago Transit Authority's Infrastructure Using Spatially Referenced Asset Management

摘要

The Chicago Transit Authority (CTA) is the second largest transit agency in the United States. Sections of this rail system are over a hundred years old and both train stations and related infrastructure are aging. In order to effectively manage and maintain station assets, the agency has developed a systematic inventory of assets and conditions. This paper describes methods to access, query and display the data using a geographical information system (GIS) and relational databases, to facilitate both strategic and day-to-day decision-making.
