“…In both scenarios, sulfur dioxide (SO 2 ) emissions increase, up to 12% in the T-F scenario. In 2005, fuel standards for highway diesel contained 500 ppm sulfur, , while railroad diesel contained 2600 ppm, , so increased freight rail yields increased SO 2 emissions. New EPA regulations are stepping down both highway and rail diesel sulfur levels to 15 ppm by 2015.…”

“…The overall structure of our study design is presented in Figure , with each component discussed in detail in Supporting Information, section S1. We have developed a policy-relevant emissions inventory (WIFE version 1.5; earlier version discussed in Johnston et al, 2012) to allow for multicorridor, multicommodity, multipollutant emissions inventory calculations. WIFE incorporates HDDV freight activity from the Federal Highway Administration’s (FHWA) Freight Analysis Framework (FAF) version 2.2 , database and HDDV emissions factors from the EPA’s MOBILE6.2 emissions model. , Freight rail emissions were calculated on the basis of published rail emissions factors (see Table S3 and section S3 in the Supporting Information).…”

We present an examination of the potential emissions and air quality benefits of shifting freight from truck to rail in the upper Midwestern United States. Using a novel, freight-specific emissions inventory (the Wisconsin Inventory of Freight Emissions, WIFE) and a three-dimensional Eulerian photochemical transport model (the Community Multiscale Air Quality Model, CMAQ), we quantify how specific freight mode choices impact ambient air pollution concentrations. Using WIFE, we developed two modal shift scenarios: one focusing on intraregional freight movements within the Midwest and a second on through-freight movements through the region. Freight truck and rail emissions inventories for each scenario were gridded to a 12 km × 12 km horizontal resolution as input to CMAQ, along with emissions from all other major sectors, and three-dimensional time-varying meteorology from the Weather Research and Forecasting model (WRF). The through-freight scenario reduced monthly mean (January and July) localized concentrations of nitrogen dioxide (NO2) by 28% (-2.33 ppbV) in highway grid cells, and reduced elemental carbon (EC) by 16% (-0.05 μg/m(3)) in highway grid cells. There were corresponding localized increases in railway grid cells of 25% (+0.83 ppbV) for NO2, and 22% (+0.05 μg/m(3)) for EC. The through-freight scenario reduced CO2 emissions 31% compared to baseline trucking. The through-freight scenario yields a July mean change in ground-level ambient PM2.5 and O3 over the central and eastern part of the domain (up to -3%).

Abstract:The Chinese government has long been preoccupied with solving the problem of overloaded trucking in intercity freight systems (IFSs). The enforcement of prohibiting overloaded trucking, which enhances environmental and social performance of sustainability, has not progressed well, as it raises transport costs and lowers economic performance, and cannot improve the overall performance of sustainability. It is, thus, necessary to find a way to eliminate overloaded trucking without undermining the overall performance of sustainability. A modal shift is a potential way to achieve freight sustainability, by encouraging greater use of more efficient transport modes. This paper develops a system dynamics model to perform a long-term evaluation of alternative modal shift policies with trucks meeting the statutory limit, and then identified effective policies, whereby the increasing sustainability of IFSs could be achieved. The proposed model was applied to a specific case in China. The results show that the effective modal shift policy is to construct a Class I railway to shift freight away from highways. A discussion is then proposed, based on an analysis of different parameter setting scenarios regarding more general situations.
