How the Chicago Marathon will keep track of 1.7 million people
Northwestern University engineering professor and INFORMS member Karen Smilowitz and her team of students will utilize a race-simulation program to produce a real-time model of the race by combining data from previous Chicago marathons with periodic updates from the checkpoints. The system analyzes the information and can predict, for example, where runners will be if the temperature rises dramatically. With this information, personnel can foresee how many runners might seek help at certain aid tents along the course and then transfer volunteers to be where they are needed.
