Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

39 Database Dictionary This appendix shows the data items included in the database of transit impact case studies. It also shows how this data- base is modified from the data dictionary that was originally developed for highway case studies as part of SHRP 2 Project C03. Items that have been modified from the original data- base are showing in italics. Items that have been added to the new database for transit cases are displayed in bold. All items that were used in the original database are also included in the transit database unless otherwise noted, although some are not displayed in the pilot web tool. Those items that were included in the highway impact database but excluded from the transit impact database design are shown with strikethroughs.

TRB's Transit Cooperative Research Program (TCRP) Report 186: Economic Impact Case Study Tool for Transit presents the results of a project aimed at creating the prototype for a searchable, web-based database of public transit investment projects and their associated, transit-driven economic and land development outcomes. This information is intended to inform future planning efforts for transit-related projects, and to support better multi-modal planning.

This TCRP project builds upon a database established for highway projects under TRB’s second Strategic Highway Research Program (SHRP2) called Transportation Project Impact Case Studies (TPICS). The purpose of TPICS is to provide transportation planners with a consistent base of data on actual, documented economic and land development impacts of completed transit-related investments, along with descriptions of the nature and associated factors of the impact.

The report covers the design and development of the case study database and web tool, and includes a set of seven prototype case studies. The web tool and prototype cases can be found at http://transit.tpics.us.
