ACM SIGSPATIAL Cup 2025: Human Mobility Prediction Challenge


This is the 14th SIGSPATIAL Cup competition (GISCUP 2025), co-located with the 2025 ACM SIGSPATIAL conference. The goal of this annual contest, hosted by SIGSPATIAL, is to encourage innovation in a fun and active way. The winners will be announced at the ACM SIGSPATIAL conference in November 2025. Contest participants will submit solutions and a report that would describe the solution approach by the deadlines mentioned in the Submit page.

The 2025 contest will focus on:

Prediction of Human Mobility Patterns in Multiple Cities

Understanding, modeling, and predicting human mobility trajectories in urban areas is an essential task for various domains and applications. The recent availability of large-scale human mobility data collected from mobile devices have enabled the development and testing of complex human mobility models, resulting in many articles published in venues such as ACM SIGSPATIAL. However, human mobility prediction methods are trained and tested on different datasets due to the lack of open-source and large-scale human mobility datasets amid privacy concerns, making it difficult to make fair comparisons of other methods’ performances. The lack of large-scale open-source datasets has been one of the key barriers hindering the progress of human mobility model development.

Following the success of HuMob Challenge 2023 @ ACM SIGSPATIAL 2023 and HuMob Challenge 2024 @ ACM SIGSPATIAL 2024, we will host this year’s HuMob Challenge as a GISCUP, using a synthetic but realistic human mobility dataset of 20K~150K individuals’ trajectories per city, across 75 days in 4 metropolitan areas provided by LY Corporation (previously Yahoo Japan). Participants will develop and test methods to predict human mobility trajectories using the provided open-source dataset.
