Abstract:This report summarizes background research and presents an analysis template for analyzing the
emissions from vehicle delay at land ports of entry along the United States-Mexico border. The analyses
template is presented along with two case studies. Results from the case studies identify candidate best
practices and performance measures for use as an input during the initial phases of development for
projects that alter the border infrastructure or the operational characteristics of the ports of entry. A set of
operating mode distributions and average speed data for use with emission factor modes such as MOVES,
EMFAC, or MOBILE is developed based on a detailed microsimulation analysis of the Bridge of the
Americas and the Ysleta-Zaragoza port of entry. Vehicle activity is assigned to either uncongested
movements or queues, with queues further broken down to stop-and-go queues or creeping queues. This
breakout of the emissions and vehicle activity is then used to analysis specific case studies to add users in
extending the analysis template to their own analysis needs. Background research is available separately.
