The Incredible Return on Investment of Cycling Infrastructure, Certified by the World Bank
A groundbreaking tool developed by the World Bank in collaboration with the Institute for Transportation and Development Policy (ITDP) now measures the economic profitability of cycling infrastructure using the same metrics applied to highways and railways. An analysis of eight projects revealed internal rates of return (IRR) ranging from 41% to 123%. Notably, these quantified benefits represent only a fraction of the actual advantages.
Bridging the Investment Gap
Traditionally, when a mobility commissioner presents a cycling network project to the council, the justification often rests on qualitative benefits such as health, environmental impact, and quality of life. In contrast, proposals for road expansions are typically backed by cost-benefit analyses, net present value (NPV), and internal rates of return. This disparity has influenced urban planning decisions for decades, not because cycling infrastructure is less profitable, but because there was no standardized tool to demonstrate its economic value.
Introducing CyclingMAX: A Financial Perspective on Cycling Infrastructure
Enter CyclingMAX, the centerpiece of “The Case for Cycling Infrastructure Investments,” a report published by the World Bank in partnership with ITDP and Progress Analytics. CyclingMAX is a web-based cost-benefit analysis model that provides two key financial metrics: net present value (NPV) and economic internal rate of return (EIRR). These are the same metrics used by development banks to evaluate investments in dams, ports, or metro lines.
This approach signifies a paradigm shift, allowing cycling projects to be evaluated alongside road infrastructure using consistent financial criteria. In the language of public finance, this transforms a proposal into a compelling investment opportunity.
Real-World Applications: Impressive Returns
The report applies the CyclingMAX model to eight real-world projects:
-
Abidjan, Ivory Coast: An investment of $6 million yielded an EIRR of 123.5% and an NPV of $52 million.
-
Recife, Brazil: $55.5 million invested resulted in a 91.5% EIRR and an NPV of $594 million.
-
São Paulo, Brazil: EIRR of 88.6%.
-
Lima, Peru: EIRR of 85.7%.
-
Addis Ababa, Ethiopia: EIRR of 75.7%, generating an NPV of $689 million from an investment of $118 million.
-
Dodoma, Tanzania: The least impressive in the sample, with an EIRR of 41.6%.
The most striking case is Kampala, Uganda: an investment of $131 million for 493 kilometers of cycling lanes produced an NPV of $1.08 billion—eight times the initial investment.
These figures are particularly compelling when compared to discount rates ranging from 6% to 12%, the threshold below which public investments are typically deemed unjustifiable. All eight projects exceed this threshold by a factor of four to ten, indicating robust economic viability.
Understanding the Metrics
The credibility of a cost-benefit analysis lies in its methodology. CyclingMAX monetizes four categories of benefits:
-
Road Safety: Reductions in traffic accidents due to increased cycling infrastructure.
-
Health: Improvements in public health from increased physical activity.
-
CO₂ Reduction: Decreased carbon emissions from reduced car usage.
-
Travel Time Savings: Efficiency gains from dedicated cycling lanes.
The model requires inputs such as project location, infrastructure length, construction and maintenance costs, and the population within a 300-meter radius of the proposed route.
A Conservative Estimate
It’s important to note that the report explicitly states that certain benefits were excluded from the calculations, including impacts on local commerce, congestion reduction, decreased absenteeism, pollutants other than CO₂, improved perceived quality of the route, and intersection interventions. These exclusions were made for methodological prudence, as they required local data not always available or assumptions that were too tenuous. Therefore, the reported results are likely an underestimation of the actual benefits.
A Transferable Methodology with Caution
While the case studies are all from African and South American cities, and the model’s internal parameters are calibrated for low and middle-income contexts, the methodology itself is transferable. The existence of a validated framework by an international financial institution that treats cycling infrastructure as an investment assessable with NPV and EIRR shifts the discussion’s focus. Cycling projects can now be evaluated using the same criteria as road infrastructure, and they win the comparison.
However, it’s crucial to recognize that the real imbalance is cultural rather than technical. No one is asked for the internal rate of return of a roundabout, a parking lot, or a lane expansion. These projects proceed because they always have. Now that the financial case for cycling exists, articulated in the language that public budgets understand, the burden of proof can finally shift.
In conclusion, the World Bank’s CyclingMAX tool provides a robust, financially sound argument for investing in cycling infrastructure, demonstrating that such projects are not only beneficial for public health and the environment but also offer substantial economic returns.
