A synthesis of the questions raised during a freight seminar of the 1967 RAND/HUD/DOT Summer Program in Urban Transportation, revised and republished for the December 1970 Conference on Urban Commodity Flow sponsored by the U.S. Department of Transportation (DOT) and Canadian Transport Ministry. Primarily, it is a list of issues under these major topics: movement of urban freight; interaction of freight and passenger traffic; freight transport as a component of urban society, user of urban land, and tool in urban development; and the government role in fostering new technology and in regulation. Most of the issues of 1967 are still pressing today, but some have been ameliorated. Containerization has progressed, and DOT now has a special office to centralize information about freight transport. 30 pp.
