The Fractal and Multifractal Nature of Traffic
Traffic flow has traditionally been viewed either as a stochastic process, or as a kinematic fluid. In the case of the former usually only the equilibria and mean results have been of interest. In the latter situation traffic has been viewed as having a continuous differentiable density (perhaps with occasional shocks). Neither of these properly address the nature of traffic if the inherent tra...
متن کاملDetecting Anomalous Trajectories from Highway Traffic Data
In this paper we modify our unsupervised anomaly detection algorithm [1,2] and apply it to highway traffic anomaly analysis. We propose a method to identify anomalies under a probabilistic framework. Instead of determining anomalies based on the size of each cluster, they are determined in a probabilistic framework. Moreover, we present our findings on using different features when analyzing re...
متن کاملSelf-similar and fractal nature of internet traffic
The self-similar bursty Internet traffic is usually characterized by the Hurst parameter (H). Such a process is also seen to possess fractal characteristics in time described by a parameter (b), with multifractals in most cases. We observe that these highly stochastic traffics have fractals in flow density too, described by a fractal dimension (D), also with the possibiliy of multifractals as i...
متن کاملLUNT AND WILSON: NEW DATA SETS AND HIGHWAY TRAFFIC MODELS New Data Sets and Improved Models of Highway Traffic
In this paper we report progress on the use of novel data sets to calibrate and improve car-following models of highway traffic. These models describe vehicles as discrete entities moving in continuous time and space, and use plausible behavioural assumptions to derive systems of differential equations which must be solved for vehicles’ trajectories. To date, there has been little or no systema...
متن کاملFractal Behavior of Video and Data Traffic
A fractal is a function or a process in which an identical motif repeats itself on an ever diminishing scale. The motif of a fractal can be a feature influenced by chance. Fractals can be found in nature everywhere, for instance the surface of the moon is a fractal, where the motif of craters is repeated in a scale from inches to miles. It is created by random collisions with space objects. Fra...
