# Introduction

This is the user manual of the Urban Health Impact Assessment Tool (upthat). It focusses on using the tool via an interactive web application, currently hosted at https://atfutures.github.io/uta/. For more advanced documentation, see the scenarios report and the adaptation manual.

# User interface

The user interface (UI) shown below has four main components:

• Interactive map: this allows the user to zoom, pan and even tilt the city, using controls that are documented in the mapdeck R package (Cooley 2019)
• City: this is used for changing cities
• Scenarios: this dropdown menu allows users to choose from a range of pre-specified scenarios
• Mode: selecting different modes from this dropdown menu reveals estimated flows of that mode on the road network

# Outputs

The two main outputs of the tool, for a given scenario, are:

1. Estimates of where active transport levels are likely to be highest
2. Estimates of the health impacts of different scenarios (work in progress)

# Running upthat locally

Upthat is a fully open and reproducible web application. You can reproduce it on your computer on a local installation of R as follows:

devtools::install_github("atfutures/upthat")
library(upthat)
upthat::runUpthat()
