The U.S. Army Corps of Engineers (USACE) is responsible for the maintenance of federally authorized navigation channels and associated infrastructure. As such, USACE requires objective performance measures for determining the level of service being provided by the hundreds of maintained navigation projects nationwide. To this end, the U.S. Army Engineer Research and Development Center partnered with Texas A&M Transportation Institute to develop a freight fluidity assessment framework for coastal ports. The goal was to use archival automatic identification system (AIS) data to develop and demonstrate how ports can be objectively compared in relation to fluidity, or the turnaround time reliability of oceangoing vessels. The framework allows USACE to evaluate maintained navigation project conditions alongside port system performance indices, thereby providing insight into questions of required maintained channel dimensions. The freight fluidity concept focuses on supply chain performance measures such as travel time reliability and end-to-end shipping costs. Although there are numerous research efforts underway to implement freight fluidity, this is the first known application to U.S. ports. This paper covers AIS data inputs, quality control, and performance measures development, and also provides a demonstration application of the methodology at the Port of Mobile, Alabama, highlighting travel time and travel time reliability operating statistics for the overall port area. This work provides foundational knowledge to practitioners and port stakeholders looking to improve supply chain performance and is also valuable for researchers interested in the development and application of multimodal freight fluidity performance measures.
This paper introduces port authority transportation reinvestment zones (TRZs), a funding tool created by the Texas Legislature to help fund long-term economic development port projects. TRZs were first introduced in Texas in 2007 as a tool to allow county and municipal governments to raise funds to help pay for transportation improvements using the property tax mechanism. Since then, the legislation has been amended to include other transportation modes, such as transit, rail, and parking facilities. Amendments passed in 2013 introduced the concept of port authority TRZ, which expanded authorized use of the tool to the state’s port authorities and navigation districts. Most of the existing funding tools available to Texas ports focus on the development of infrastructure within port property. Port authority TRZs complement existing funding sources by providing a funding tool flexible enough to fund port projects both inside and outside port property. Port authorities can take advantage of the TRZ concept to join forces with neighboring local governments and the Texas Department of Transportation to fund landside transportation enhancements that improve port accessibility and the regional economy. Currently, there are four active port authority TRZs in the following locations: Port of Beaumont, Port of Port Arthur, Port of Brownsville, and Sabine-Neches Navigation District. This paper summarizes the legal framework of port authority TRZs, describes the role that these TRZs play in port funding and finance, and presents highlights of the port authority TRZs that have already been established throughout the state.
Data from 2001 to 2009 were used to update the 2009 modal comparison study conducted by the Texas Transportation Institute, which used data from 2001 to 2005. The objective was to develop performance measures of rates per ton-mile to facilitate multimodal comparisons between inland towing, rail, and truck in six topical areas: cargo capacity, traffic congestion, energy efficiency, air quality, safety, and infrastructure. The study focused on several vital issues from a snapshot in time. Credible publicly available and independently verifiable data from federal, industry, and academic sources were used. The scope of the study and several data limitations necessitated the use of assumptions that were based on sound engineering principles, as well as development of innovative methods, to arrive at plausible results and fulfill the study's unconventional objectives. The study results showed that waterborne transportation continued to compare favorably with rail and highway modes for the examined performance measures. Any waterborne freight diversion to either of the two modes likely would result in serious negative effects on freight transportation operations and in possible system breakdowns. Chain reaction effects would jeopardize the well-being of the general public and the national economy.
This paper summarizes the findings of research conducted for the Texas Department of Transportation (DOT) that produced a master plan for the Gulf Intracoastal Waterway in Texas (GIWW-T). The project (a) established a baseline for the condition and utilization of the GIWW-T; (b) examined the major operational concerns, mostly related to dredging and navigational safety; (c) investigated the impacts of operational obstacles; (d) determined what is needed to restore the GIWW-T to and sustain its optimum level; (e) investigated potential economic and legislative limitations; and (f) recommended potential courses of action that might enable the Texas DOT to play an active role in achieving a highly efficient and safe GIWW-T. A working group of GIWW-T stakeholders informed the research. Participants included the U.S. Army Corps of Engineers, the U.S. Coast Guard, port authorities, the Texas DOT, and barge industry representatives.
