Abstract Averaging GPS trajectories is needed in applications such as automatic generation of road network and finding representative movement patterns. We organized a challenge where participants submitted proposals to solve the averaging problem. In this paper, we review the proposals and evaluate their performance. We present a synthesis of the submitted methods and develop a new baseline composed of the well-performing components. The new baseline outperforms all existing averaging methods. All datasets, submissions and evaluations can be accessed on the competition webpage: http://cs.uef.fi/sipu/segments .

2019 年平均 GPS 细分市场竞争

摘要 在自动生成道路网络和寻找具有代表性的运动模式等应用中，需要平均 GPS 轨迹。我们组织了一个挑战，参与者提交解决平均问题的建议。在本文中，我们审查了这些提案并评估了它们的性能。我们对提交的方法进行了综合，并开发了一个由性能良好的组件组成的新基线。新基线优于所有现有的平均方法。所有数据集、提交和评估都可以在竞赛网页上访问：http://cs.uef.fi/sipu/segments。
