Methods for Generating Travel Time Representation from Probe Vehicle Data

This paper presents two methods for generating representative travel times from probe vehicle data. The methods are based on statistical analysis (LLsF) and signal processing (EMD) respectively. We show that the EMD method is more capable of capturing detailed fluctuations of the raw probe data. Depending on the purpose of the application, users can select an appropriate representation as needed. The study presented in this paper is still preliminary and future research directions are thus suggested to further verify both methods.
