Why the connections matter
Nobody rides a project. People ride from a front door to a school, a shop, a station or a job. A new cycle lane can improve part of that journey while leaving a difficult crossing or a missing connection unresolved. Counting kilometres tells us something important about what a city has provided. Understanding how those kilometres fit together tells us more.
Researchers, city authorities and cycling organisations have long recognised this. Established approaches provide important foundations, including PeopleForBikes’ Bicycle Network Analysis, which measures how well low-stress routes connect people to the places they need to reach, and ITDP’s measure of how many people live near protected cycling infrastructure. This report builds on that work. We want to make evidence about infrastructure useful across a varied set of urban areas, and make its limitations visible enough to challenge.
For this first edition, we have selected 750 urban areas for analysis. Almost one in three has fewer than 250,000 residents, and more than a third are in Asia. This is a deliberately selected benchmark, rather than a statistically representative sample of the world’s cities. It brings places of different sizes and circumstances into a shared investigation.
I want Asia to help shape how we understand that evidence. Its cities encompass many different street patterns, transport systems and cycling traditions. Research and practical experience from across the region should inform how we read the results, the definitions we refine and the explanations we offer. Any changes arising from that input will be recorded in the analysis plan. A global comparison has to be willing to learn from the places it measures.
That responsibility begins with examining our own assumptions. Our headline index credits a quiet street only where it is mapped as a cycle route, and its access measure counts only the lowest-stress routes: those away from motor traffic, and mapped cycle routes on calm streets. An ordinary calm street with no such mapping receives no scored credit, even where it may support everyday cycling. The importance of that omission needs to be tested locally. High cycling participation cannot establish that conditions work well for everyone; equally, an infrastructure score cannot describe the whole relationship between a city and the people who cycle in it.
The first edition examines three aspects of provision: the amount and type of qualifying infrastructure, the share of the low-stress network in its largest connected piece, and how many residents live near the lowest-stress routes. These measures can reveal patterns worth investigating. They cannot establish that every crossing is comfortable or every destination reachable. Our access measure counts residents within 300 metres as the crow flies, which can overlook barriers between a home and a route.
We use open data, including OpenStreetMap, the Global Human Settlement Layer and WorldPop. These sources make broad comparisons possible, but their coverage and detail vary. A sparse map may reflect missing records as well as missing infrastructure. We disclose those limitations and withhold the headline score when a required measure cannot be calculated.
We have published our research questions and analysis plan before the results. Version 1, dated 5 November 2026, records the questions this edition sets out to test. Alongside the results, we will publish the data versions, definitions and checks behind each finding. We will explain changes to the analysis and distinguish what we observed from what we think might explain it. Surprising results deserve closer examination, including scrutiny of the measure itself.
The purpose is to help people responsible for streets ask sharper questions. Which parts of a network remain disconnected? Which neighbourhoods warrant closer attention? Where does the map need correcting, and where does the method need improving?
I particularly welcome scrutiny from researchers, practitioners and cycling organisations across Asia, and from anyone whose knowledge of a place challenges our interpretation. A useful index should make those conversations better informed.
