... A-2 situations for which OMDs are presented in this case study. These representative drive cycles will continue to be applicable in future versions of MOVES even if the OMD conversion parameters change.

From page 4...
... A-4 In this case study, custom operating mode distributions were gathered from existing studies for different scenarios, including port traffic, border crossings, on ramps, and traffic incidents. The Excel file that accompanies this guidebook catalogues these custom operating mode distributions.
From page 5...
... A-5 A.6 Findings from Sample Data A.6.1 Overview The custom scenarios tested, organized by source, were: • FHWA Advances in Project-Level Analysis study: – Actuated signalized arterial; Volume/Capacity (V/C) ratio 0.70.*
From page 6...
... A-6 • United States-Mexico Land Ports of Entry Emissions and Border Wait-Time White Paper and Analysis Template study (i.e., El Paso Border Crossing study) : – Border crossing, uncongested links.*
From page 7...
... A-7 • For the field data collection and simulation-based El Paso Border crossing study, custom operating mode distributions produced considerably lower emissions rates than the defaults for all scenarios and links. • For the data collection-based Houston-Galveston Port Drayage study, the custom operating mode distribution produced somewhat lower emissions rates than its default counterparts.

Guide to Truck Activity Data for Emissions Modeling A-35 A.7 Transferability This case study illustrates relative differences in emission rates by project context, but the illustrative emission factors should not be used to apply actual emission rates locally. Instead the project sponsor should use a representative operating mode distribution in combination with other locally appropriate MOVES inputs.
