Abstract:This report updates the previous modal comparison study released by the Texas A&M Transportation Institute (TTI) in January 2017. That study used data from 2001–2014. This study includes data from 2001–2019 (2019 is the most recent year for which data are generally available for all three modes). Inland waterway traffic continues to compare favorably to the other two modes in each category of impacts. The following topical areas were covered in this research: cargo capacity, congestion, emissions, energy efficiency, safety impacts, and infrastructure impacts. The analysis is predicated on the assumption that cargo will be diverted to rail or highway (truck) modes in the event of a major waterway closure. The analysis considered the possible impacts resulting from either a diversion of 100 percent of the current waterborne cargo to the highway mode or a diversion of 100 percent of the current waterborne cargo to the rail mode. This report presents a snapshot in time in order to focus on several vital issues. The data used in this research are publicly available and can be independently verified and used to support various analyses.
