Today's public transit vehicles produce a large amount of automatic vehicle location (AVL) data. This data is very useful for planning and performance studies, but can be noisy, error-prone, and sparse. This package provides tools for cleaning AVL point data and turning it into continuous, differentiable, monotonic, and invertible vehicle trajectory functions, based on the work of Robbennolt et al. (2025) <doi:10.48550/arXiv.2509.00119> and Huang et al. (2023) <doi:10.1109/ITSC57777.2023.10422524>.
