Emergency response, evaluation and disaster relief

Write the memo of a theme;
The Disaster Relief Trials aims to test the potential for bicycles, specifically cargo bicycles, to help bring in aid and relief and serve as a mechanism for evacuation in the event of a natural or man-caused disaster. Write a memo that discusses the feasibility of their aims, barriers to bringing their perspective to cities other than Portland, and limitations to their approach. Also relate to some of the issues in the scholarly and popular literature.
If it is useful, focus on another city/location around the world and contrast how the DRT proposal could be implemented there. Or discuss how these bicycles would be useful for a specific type of disaster (earthquake, flood, hurricane, war, etc.). Include your own perspective on the utility of these bicycles to serve needs in the face of an emergency.
