Package: gps2gtfs 0.6.0

gps2gtfs: High-Performance GPS to GTFS Converter

Preprocesses raw GPS trajectory data of public transit and transforms it to GTFS format. Provides a high-performance R port of the 'gps2gtfs' Python package by Aaivu (Ratneswaran et al., 2023) <doi:10.1109/ICCT56969.2023.10075789>, whose software description is published in Ratneswaran et al. (2025) <doi:10.1016/j.simpa.2025.100780>. Heavy computational tasks are offloaded to an extremely fast compiled Rust backend or a C++ (Rcpp) backend. Automatic backend selection prefers Rust, then Rcpp, and falls back to a slower pure R implementation utilizing 'data.table' and 'sf'.
