Compute travel time matrices

This is a Python package to handle the high-level logic of computing travel time matrices for multiple travel modes using r5py.

This package is used, for instance, for calculating travel time matrices of the Helsinki metropolitan area (in a Docker container), but can be used by itself, as well.

Installation

pip install git+https://github.com/DigitalGeographyLab/travel-time-matrix-computer.git

Use

Create a data directory, within that a config file according to the template provided in travel_time_matrix_computer.yml.example, and pass it to python -m travel_time_matrix_computer

Dependencies

This package depends on r5py, car_speed_annotator, cycling_speed_annotator, and parking_times_calculator, as well as all dependencies listed there (i.e., a Java JRE and osmium, which is available as a package for most Linux distributions: e.g., osmium-tool on Ubuntu and Arch).

Output data aggregation and packing can be sped up by installing the optional dependency 7za (available as p7zip on Ubuntu, Arch, and most likely most Linux distributions)
