Judges commentary 337 Judge's Commentary The Outstanding Hurricane Evacuation Papers Mark parker Department of Mathematics, Engineering, and Computer Science Carroll college Helena, mr 59625 marker@carroll. edu http://web.carroll.edu/mparker Introduction Once again, Problem B proved to be quite challenging-both for the stu- dent teams and for the judges! The students were challenged by a multifaceted problem with several difficult questions posed, and the judges were challenged to sort through the wide range of approaches to find a small collection of the best papers. It is worth reminding participants and advisors that Outstand- ing papers are not without weaknesses and even mathematical or modeling errors. It is the nature of judging such a competition that we must trade off the strengths, both technical and expository, of a given paper with its weaknesses, and make comparisons between papers the same way. The approaches taken by this year's teams can be divided into two genera categories: Macroscopic: Traffic on a particular highway or segment of highway was con- sidered to be a stream and a flow rate for the stream was characterized Among the successful approaches in this category were fluid dynamics and network flow algorithms Microscopic: These can be considered car-following models, where the spacing between and the speeds of individual vehicles are used to determine the flow. Among the successful approaches were discrete event simulations (including cellular automata)and queuing systems The UIMAP Journal 22(3)(2000)337-343. @ Copyright 2001 by COMAP, Inc.
