Case Studies of Truck Activity Data for Emissions Modeling

This document presents seven case studies that are appendices A to G of NCHRP Report 909: Guide to Truck Activity Data for Emissions Modeling. NCHRP Research Report 909 explores methods, procedures, and data sets needed to capture commercial vehicle activity, vehicle characteristics, and operations to assist in estimating and forecasting criteria pollutants, air toxics, and greenhouse gas emissions from goods and services movement. The case studies address: representative operating mode distributions for different project contexts; age distributions from inspection station data; truck starts and soak time from GPS data; truck extended idling and starts from fleet telematics data; speed distributions from the National Performance Management Research data set; truck activity analyses from localized fleet telematics data; and representative drive cycles for different project contexts.
