This brief summarizes findings from researchers at the University of Southern California who developed an optimization-based vehicle scheduling model that allows for a “street exchange” in which empty containers can go directly from importers to exporters without returning to the port.

This study demonstrates a model framework that combines a microscopic traffic simulation with emissions and microscale dispersion models to quantify the potential impacts of truck-only lanes on fuel consumption, emissions, and near-road pollutant concentrations.

The study collected information through a web-based stated preference survey sent to fleets and carrier companies to gather data about their economics, and their vehicle purchase preferences. The project also developed a multi-criteria decision-making tool using a Spherical Fuzzy Analytical Hierarchy Process based on experts’ knowledge.
