TRB’s Transit Cooperative Research Program (TCRP) Web-Only Document 44: Literature Review for Providing Access to Public Transportation Stations describes the results of the literature review examining various alternatives for providing access to and from stations of new and mature high-capacity public transportation systems, including heavy rail, light rail, commuter rail, and bus rapid transit.

In 2012 TRB released TCRP Report 153: Guidelines for Providing Access to Public Transportation Stations, which was produced by the same project that produced TCRP Web-Only Document 44.  TCRP Report 153 is intended to aid in the planning, developing, and improving of access to high capacity commuter rail, heavy rail, light rail, bus rapid transit, and ferry stations. The report includes guidelines for arranging and integrating various station design elements.
