TG‐GPT: A Generative Pre‐Trained Transformer With Gated Recurrent Units for AIS‐Based Ship Trajectory Prediction

open access: yesThe Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This study proposes TG‐GPT, a lightweight ship trajectory prediction model that integrates a GRU with a tiny GPT to improve short‐term accuracy and reduce computational cost. Tested on over 1.2 million AIS records, TG‐GPT significantly outperforms state‐of‐the‐art models, reducing MAE by up to 87% for specified routes and 9% for random predictions ...

Mapping Our Cities for All: A participatory baseline of business accessibility in Canada

open access: yesCanadian Geographies / Géographies canadiennes, Volume 70, Issue 1, Spring / printemps 2026.
Abstract Canada has committed to eliminating accessibility barriers by 2040, yet municipalities lack clear, comparable evidence on where building access breaks down. To address this gap, we set out to produce and test a participatory, city‐scale method to measure building accessibility of businesses. We report results from Mapping Our Cities for All, a

A GIS‐Based Framework for Modeling Hospital Accessibility in Spain Using Open and Collaborative Data

open access: yesGeographical Analysis, Volume 58, Issue 1, January 2026.
ABSTRACT This study analyzes hospital accessibility in Spain at the census section level from 2010 to 2024. Using open data and open‐source tools, a replicable geospatial method was developed to estimate travel times and distances to the nearest hospital by car and on foot. Over 500,000 origin–destination pairs were analyzed, combining census centroids,
