Replication code for:

Roberts, H. S., Calastri, C., Batley, R. (under review) "Evaluating open-source approaches for estimating level-of-service attributes in transport choice modelling". Manuscript submitted for publication.

Overview

This repository contains the code used to process travel survey data, compute routing attributes using three methods, and estimate revealed-preference choice models.

Repository structure

• input/raw/ – raw input data (not included)
• input/processed/ – processed datasets (not included)
• R/ – processing and modelling scripts
• output/ – model outputs and figures (not included)
• docs/ – workflow documentation

Workflow

The complete workflow is documented in: 👉 docs/workflow.html

Data availability

The following inputs are not included:

• DECISIONS survey data (due to privacy concerns)
• OS Multimodal Routing Network (due to licensing restrictions)
• Google Routes API key

Requirements
