Description

TRB's Transit Cooperative Research Program (TCRP) Report 138: Estimating Soft Costs for Major Public Transportation Fixed Guideway Projects defines and describes soft costs and provides a new suggested methodology to estimate soft costs based on historical projects. The report also examines detailed technical information about the data collection, methodology, and statistical analysis that was used to develop the suggested methodology.

Topics
