A pilot test implemented a radio frequency identification (RFID) system to automatically measure travel times of US-bound commercial vehicles at a selected Port of Entry (POE) on the US‒ Mexico border under long-term, real-world conditions. The initiative began with a Part 1 technology trade-off study of potential detection technologies to measure travel(More)
This project was co-sponsored by the Southwest University Transportation Center (SWUTC) and Region 6 of the United States Environmental Protection Agency (EPA), and the Border Environment Cooperation Commission. The overall goal of the project was to develop a methodology and to apply this methodology to estimate emissions produced by trucks from Mexico(More)
A system dynamics model is proposed for analyzing the uncertainty caused by delays and disruptions at the U.S.–Mexican border, and how their effects propagate through the cross-border supply chains. Since Mexico's geographic proximity and low wages provide logistics advantages to North American Free Trade Agreement (NAFTA), it is becoming a favored(More)

Biotechnological processes with lignocellulose materials are promising technologies for the production of chemicals and energy involving the same main production stages: hydrolysis of the hemicel-lulose and the cellulose to monomeric sugars, fermentation, recovery of the product, and concentration. We studied the effect of different treatments on the(More)
There is no reliable system in place to measure and report border crossing times to either commercial trade or travelers planning to cross the U.S.-Mexico border. This research project, in combination with three other already funded and ongoing projects, provides a prototype of such a system. The result is a real-time international border crossing travel(More)
