Personalized Prediction of Vehicle Energy Consumption based on Participatory Sensing
This work addresses the challenge of sparse data in participatory sensing for intelligent transportation applications, offering incremental improvements in prediction accuracy.
The paper tackles the problem of personalized vehicle energy consumption prediction using participatory sensing data, and shows that their approaches, including a blackbox framework and collaborative filtering, significantly improve prediction accuracy in a case study on distance-to-empty prediction for electric vehicles.
The advent of abundant on-board sensors and electronic devices in vehicles populates the paradigm of participatory sensing to harness crowd-sourced data gathering for intelligent transportation applications, such as distance-to-empty prediction and eco-routing. While participatory sensing can provide diverse driving data, there lacks a systematic study of effective utilization of the data for personalized prediction. There are considerable challenges on how to interpolate the missing data from a sparse dataset, which often arises from participatory sensing. This paper presents and compares various approaches for personalized vehicle energy consumption prediction, including a blackbox framework that identifies driver/vehicle/environment-dependent factors and a collaborative filtering approach based on matrix factorization. Furthermore, a case study of distance-to-empty prediction for electric vehicles by participatory sensing data is conducted and evaluated empirically, which shows that our approaches can significantly improve the prediction accuracy.
