# traffic - responsive geospatial visualisation app

Built with __TypeScript__, __React__, __D3__, __GeoJSON__, __TopoJson__ and __SVG__.

The app visualises part of the information about the [road traffic statistics](https://roadtraffic.dft.gov.uk/downloads) collected in the UK over 23 years (2000-2022), across 45,865 manual count points.

Traffic data is displayed over a [GeoJSON representation](https://martinjc.github.io/UK-GeoJSON/) of the selected area generated with [D3.js](https://d3js.org/).

A second chart shows the distribution of traffic in the area by vehicle type.

## Features:

• view traffic points in selected `area`, and related traffic details for each point

• see gradual evolution by modifying `year` via custom slider

• filter data by `vehicle type`

• display an animated loader while data is being fetched

• display a fallback UI if data fetching fails

The app is responsive and works on touch screen devices too.

Deployed to [kinola.it/app/traffic/](https://kinola.it/app/traffic/)
