Abstract
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 crossing the El Paso-Ciudad Juarez border
locations. The specific objectives of the study were to develop a:
* border crossing fleet profile - profile of the make, model, and year of trucks crossing the two main
border bridges;
* border crossing travel profile -profiles of the drive cycles (acceleration, deceleration, cruising,
idling, and creep idling) of trucks crossing the two main border bridges; and
* border crossing emissions profile -estimates of idling emissions and driving emissions of trucks
crossing the two main border bridges
TTI used portable emissions measurement system (PEMS) equipment along with Tapered Element
Oscillating Micro-balance (TEOM) equipment operated by Oak Ridge National Laboratory to measure the
truck emissions. The project provided good insight into the fleet, travel, and emissions characteristics of
trucks crossing the El Paso-Ciudad Juarez border locations.
