Abstract
Road sensors gather a lot of statistical data about traffic. In this paper, we discuss how a measure for the amount of traffic on the roads can be derived from this data, such that the measure is independent of the number and placement of sensors, and the calculations can be performed quickly for large amounts of data. We discuss how a graph of the road sensors can be constructed, and how the number of cars and car-kilometers can be estimated on this graph. Further, methods for dealing with missing data are presented, and the benefits of principal component analysis are discussed.
