A survey of evaluation methods for personal route and destination prediction from mobility traces

Abstract

Personal mobility data can nowadays be easily collected by personal mobile phones and used for analytical modeling. To assist in such an analysis, a variety of computational approaches have been developed. The goal is to extract mobility patterns in order to provide traveling assistance, information, recommendations or on‐demand services. While various computational techniques are being developed, research literature on destination and route prediction lacks consistency in evaluation methods for such approaches. This study presents a review and categorization of evaluation criteria and terminology used in assessing the performance of such methods. The review is complemented by experimental analysis of selected evaluation criteria, to highlight the nuances existing between the evaluation measures. The experimental study uses previously unpublished mobility data of 15 users collected over a period of 6 months in Helsinki metropolitan area in Finland. The article is primarily intended for researchers developing approaches for personalized mobility analysis, as well as a guideline for practitioners to select criteria when assessing and selecting between computational approaches. Our main recommendation is to consider user‐specific accuracy measures in addition to averaged aggregates, as well as to take into consideration that for many users accuracy does not saturate fast and the performance keeps evolving over time. Therefore, we recommend using time‐weighted measures.

A Survey for the Ranking of Trajectory Prediction Algorithms on Ubiquitous Wireless Sensors

“…The results showed that the choice of risk estimated method along with the motion model are the two major components for motion prediction and risk estimation for intelligent automobiles. Similarly, a study analyzed the different computational approaches developed for personal mobility [ 28 ]. An experimental analysis was performed on the unpublished mobility data of 15 users in the Helsinki metropolitan area.…”

Flexible synthetic mobility modeling to discover trajectories for complex areas of mobile wireless networks

“…With this purpose, these models are described by equations which take into account physical laws of motion. On the other hand, some models are inspired by real mobility traces in order to model real-life movements (Stegmann et al 2018;Ibadah et al 2018a). Notwithstanding, in all cases, the major challenge is how to achieve the best possible performance for wireless Communications in the presence of frequent mobility (Batabyal and Bhaumik 2015).…”
