Abstract
A number of strategies could reduce emissions along active freight corridors like the SPBP. These include: intelligent transportation systems (ITS), advanced traffic operations and control measures, shifting freight from trucks to trains, and increased use of clean-diesel trucks. The health impacts of such strategies should be closely studied in coming years. Our analysis is being expanded to measure health impacts of trucks not only on freeways that feed directly into the port, but also on nearby local streets and other freeways in the corridor.
