Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This thesis brings a collection of novel models andmethods that result from a new look at practicalproblems in transportation through the prism of newlyavailable sensor data. From this data, we build a model of traffic flowinspired by macroscopic flow models. Unliketraditional such models, our model deals withuncertainty of measurement and unobservability ofcertain important quantities and incorporateson-the-fly observations more easily. Having apredictive distribution of traffic state enables theapplication of powerful decision-making machinery tothe traffic domain.Secondly, a new method for detecting accidents andother adverse events is described. Data collectedfrom highways enables us to bring supervised learningapproaches to incident detection. However, a majorhurdle to performance of supervised learners is thequality of data which contains systematic biasesvarying from site to site. We build a dynamicBayesian network framework that learns and rectifiesthese biases, leading to improved superviseddetector performance with little need for manuallytagged data. The realignment method applies generallyto virtually all forms of labeled sequential data.…
