CoAXs is an open-source stakeholder engagement tool, built on Conveyal's backend, that seeks to support co-creative transport planning by allowing users to interactively view a metropolitan area's accessibilty landscape (e.g., potential to reach different types of jobs) and explore how accessibility might change through different types of public transport improvement projects, such as new bus services.
