Bristol Airmap

A public web app that helps Bristol residents discover walking and cycling routes that are healthier, greener and more enjoyable than direct alternatives. The Bristol Airmap builds on proven success from our Southampton work to unlock millions of missed opportunities for active travel across the city.

Purpose

Building on the success of the Soton Airmap and our Enhanced Green Routes for Bristol pilot, we're creating a full Bristol Airmap — a free public web app giving Bristol residents greener, healthier and more enjoyable active travel routes. The Airmap displays the multiple benefits of choosing greener walking and cycling journeys, helping people see connections between their daily travel, improved health, cost savings and environmental impact. With 34% of journeys under 2 miles still taken by car, Bristol has 103 million missed opportunities each year to boost wellbeing, reduce pollution and reconnect with nature.

Approach

  • Conducted goal-setting workshop with Bristol City Council's Transport Engagement team to align on objectives and project scope

  • Gathered and processed multiple GIS data layers including satellite imagery, noise mapping, tree canopy data and OpenStreetMap

  • First deployment of our innovative machine learning air quality model to produce high-resolution data for the entire Bristol region

  • Validated air quality outputs against local monitoring sensors across 15+ sites

  • Integrated environmental data into our routing algorithm with Go Jauntly, calculating routes optimised for lower pollution, noise and carbon

  • Coordinated Bristol City Council branding and designed for seamless integration with Bristol's Active Travel Website and Better by Bike platform

Results

The Bristol Airmap builds on proven impact from our Soton Airmap and Enhanced Green Routes pilot. It's impact is currently being monitored to produce bi-annual impact reports that will inform effective ways to reach residents and encourage healthy behaviour change. Our earlier Bristol work has already demonstrated significant potential, with residents embracing greener routes across the city.
