Travel mode detection

This repository represents the implementation of the paper:

Evaluating geospatial context information for travel mode detection

Ye Hong, Emanuel Stüdeli, Martin Raubal
IKG, ETH Zurich

Requirements and dependencies

This code has been tested on

• Python 3.10.9, Geopandas 0.12.2, trackintel 1.1.13, shap 0.41.0, scikit-learn 1.2.2

To create a virtual environment and install the required dependencies, please run the following:

    git clone https://github.com/hong2223/mode_detect
    cd mode-detect
    conda env create -f environment.yml
    conda activate mode-detect

in your working folder.

Inputs and Parameters

Require stage data with validated travel mode labels and LineString geometries as input. You can check 0_load\import_data.py for reading data from the PostGIS database and the corresponding data format. In addition, the processing scripts require the following input data and parameters:

• 1_preprocess: staypoints data for calculating user tracking quality; area shapefile for geographical filtering; stages quality parameters (tracking, length, speed for each mode, etc.) for quality filtering.
• 2_feature_extraction: geospatial context data (from OSM, Swiss Map Vector 25, or any other open-source data provider).
• 3_rf_importance: search space for hyper-parameter search.

intermediate files will be stored in ./data/ folder. Figures generated by the scripts will be stored in ./fig/ folder.
