Decision intelligence for active mobility & micromobility
Walking and cycling,measured and mapped.
How many people walk and cycle on every street. Where they face the most risk. How each street can work better. We combine it with your own data into clear insight for a single street or a whole city.
Every street moves people. Every street is also where people live.
The lenses
Multiple lenses. One picture.
Walking & cycling volumes
How many people walk and cycle on every street, modelled with DQ Flows for the whole network.
Explore →Road safety risk
Safety ratings for streets and paths with iRAP, the global standard, and CycleRAP.
Explore →Road user experience
How residents and road users experience their streets, from comfort to feeling safe.
Explore →Green & liveable streets
A clear framework for balancing space for traffic with space for people and green.
Explore →Accessibility & equity
What people can reach on foot and by bike, and who is left out without a car or a bike.
Costs & benefits
What each option costs and what it returns across your policy goals.
Our starting points
People first. However they move.
Everyone counts.
Our starting point is people and their potential to travel in many ways. We focus on walking and cycling (active mobility, also called active transport or active transportation) and on micromobility, including light electric vehicles, because traditional models often leave them out. We add motor traffic data, so you see the whole picture.
Ready for new vehicles.
E-bikes, cargo bikes, e-scooters and other light electric vehicles are changing our streets. We follow the legislation closely and plan for this growing variety: where each vehicle belongs, how it fits into traffic, and whether paths have the capacity.
Street and network.
Every lens works at both scales. We deliver network-wide data, strategies and plans, and street assessments that look at each street's role in the network. Large projects and small ones.
In practice
Questions we help answer.
Which street design works best for all users, balancing safety, liveability, climate resilience and cost?
We rate alternative designs for road safety with iRAP and CycleRAP, and weigh them against place quality and cost using ‘The Good Street’.
Where should new walking and cycling infrastructure go?
Volumes for every street show where people walk and cycle today and where demand is highest. Combined with risk, they show where new routes matter most.
How do we spend our road safety budget to save the most lives?
Combining risk scores with volumes shows where the most people face the highest risk, so upgrades go where they prevent the most harm.
Who can reach schools, jobs and healthcare, and who is left out?
We map which destinations people can reach on foot and by bike, and which groups are left out without a car or a bike.
What happens across the whole network if we redesign one street?
Scenarios show how walking and cycling volumes shift across the network when one street changes.
Where do e-scooters, cargo bikes and other light electric vehicles belong, and do our paths have the capacity?
We place each vehicle in a family by its mass, follow the legislation closely, and check whether paths and footpaths have room for them.
