Road Salt: A Primer on the Factors Affecting Supply and Demand
January 12th, 2015

The impact of winter weather on the nation’s roadways is so severe that transportation officials should consider significant up-front investment in adequate road salt supplies well before the season hits, according to a new report by the American Highway Users Alliance. The report, “Road Salt: A Primer on the Factors Affecting Supply and Demand,” finds that highway authorities that stock up on at least an average year’s worth of salt needs by the start of autumn stand to benefit greatly, as compared with those whose storage capacities or budget limitations do not allow for such stockpiling.

Emergency Evacuation Report Card
October 22nd, 2006

The potential for terrorist attacks and 2005 Hurricane Katrina’s flood destruction underscore the necessity for providing sufficient evacuation capacity from the nation’s urban areas. Yet, the Department of Homeland Security says, “Significant weaknesses in evacuation planning are an area of profound concern.” The Emergency Evacuation Report Card is an initial attempt to assess the evacuation capacity of the 37 largest urban areas – those with more than 1,000,000 population. Evacuation planning is new to US urban areas and, as a result, evacuation capacity can be expected to fall short of optimal levels. Read the full report. Continue reading
