Propagation Wave Speed Estimation of Freeway Traffic with Image Processing Tools

In this paper, we present an automated and fast method to estimate the characteristic propagation wave speeds of freeway traffic, given spatiotemporal raw data, for example from a set of induction loops. This method, the Wave Speed Estimator, utilizes image processing methods to analyze the speed and flow data map for typical wave patterns. One of the applications is the estimation of parameters of the fundamental diagram, which in turn are crucial for the calibration of traffic state estimators. The application to real-world data from Dutch freeways shows promising results. This method can be used as a part of a traffic state estimator or as a parameterizing tool for estimators which depend on the fundamental diagram.
