The Pacific Highway border crossing in Blaine, Washington, is the fourth busiest commercial crossing on the northern border and the most significant commercial crossing for Western Canada and the U.S. (USDOT/FHWA 2006). The primary commodities that flow across this border are agricultural/food, wood, and paper products (WCOG Manifest Data). These commodities are not viewed as particularly time critical, as they do not move in a strictly scheduled environment, although in fact a significant proportion of these goods are highly perishable. Both of these factors are significantly different than along the eastern portion of the northern border, where goods are flowing across the border in a time sensitive business environment that requires more precise delivery time estimates. These regional characteristics are important in understanding the current U.S. commercial vehicle transportation phenomenon and the impacts of delays, as well as in developing improvements and anticipating the consequences of change both at border crossings and within the Cascade border region as a whole.
