Active mobility

• 1. Introduction

  ›

  Active mobility goes by many names. In policy papers it is active travel, active transport, soft mobility. In daily life it is something simpler: the choice to walk or ride a bicycle instead of sitting in a car. Portland, Oregon, offers one of the sharpest illustrations of what that choice can mean at scale. Between 1990 and 2009, the city multiplied its bicycle commuting fivefold through sustained pro-cycling programs. A single American city, in under two decades, transformed how tens of thousands of people moved through it. So how does that kind of shift happen? What does it take, in terms of infrastructure, policy, and cultural change, to move people out of cars and onto their own two feet? And who benefits most when a city reorganizes itself around the human body rather than the engine? These are the questions that active mobility, in all its forms, keeps raising.

  Public Health England put a number on physical inactivity in 2016 that is hard to forget. One in six deaths in the United Kingdom every year, the agency estimated, is directly linked to not moving enough. That figure gave walking and cycling an urgency that goes beyond personal fitness. The UK's House of Commons Health Committee had already pointed in that direction in 2004, recommending cycling and walking specifically as key tools for fighting obesity. The PHE report that followed built on this by linking daily walking and cycling to reductions in cardiovascular disease, type 2 diabetes, cancer, and several mental illnesses, including depression.

  Cyclists and walkers relate to urban space in a way that drivers cannot. Cars filter out sensory inputs that active travel exposes: street sounds, smells, the faces of neighbors. Proponents of active mobility argue that this exposure promotes a feeling of community and connection, with measurable effects on mental wellbeing. The US Centers for Disease Control has endorsed access to active transportation as a public health priority, and multiple American studies have called for that access to extend to children as well as adults.

  Electric bikes add a dimension that traditional cycling research did not anticipate. In a study of seven European cities, e-bike users showed energy expenditure that was 10% higher each week than conventional cyclists. People who switched to e-bikes from private cars or public transit gained between 550 and 880 Metabolic Equivalent Task minutes per week in physical activity. Researchers have also noted that electric bikes may function as a cycling enabler for women, lowering the threshold for entry in places where terrain or distance has kept women from riding.

• 3. Carbon and the City

  ›

  A typical car emits 4.6 metric tons of carbon dioxide every year. That figure is not abstract: it is the baseline against which every cycling trip and every walk can be measured. In New Zealand, active mobility has been found to reduce annual carbon dioxide emissions by 1%. Across a study of seven European cities, researchers found that individual shifts toward active travel deliver significant lifecycle carbon benefits even in urban contexts that already have relatively high rates of walking and cycling. An average person who cycles one additional trip per day while cutting one car trip per day, for 200 days in a year, reduces their mobility-related lifecycle emissions by roughly half a tonne.

  Beyond carbon, vehicular traffic generates air and noise pollution that damages ecosystems and wildlife in ways that extend well past human health. Air pollution contributes to acid rain, eutrophication, haze, crop damage, ozone depletion, and climate change. Noise pollution disrupts wildlife behavior and ecosystem function. Active mobility reduces both by substituting for motor vehicles that produce greenhouse gases and noise in equal measure.

  Bikes also occupy the road differently. A bicycle takes up 8% of the space a car requires. At scale, a shift toward cycling does not just reduce emissions; it frees urban land from roads and parking lots. That land can be converted to parks and green space, which further changes the texture of city life and creates the kind of aesthetically pleasing, walkable environments that in turn make active mobility more appealing.

  Infrastructure shapes behavior before policy does. Researchers have identified a set of physical features that consistently correlate with higher rates of active mobility: wider sidewalks, street lighting, flat terrain, and urban greenery, especially parks with accessible routes. For cycling specifically, the threshold for meaningful change is higher. Bike lanes, defined by signage and road markings, reserve dedicated space for cyclists on conventional roads. Bike boxes position cyclists ahead of motor vehicles at intersections. Bicycle stations combine secure parking with basic maintenance tools. Each of these features removes a friction point that otherwise keeps potential cyclists in cars.

  Several researchers have emphasized a different variable: proximity to local amenities. Easy access to restaurants, shops, and theaters may be the single largest driver of active mobility, according to this line of research. Local governments can promote this through zoning and land-use decisions as well as through transport infrastructure. The EU organization Polis, founded in 1989 to link city and regional governments with EU institutions on transport policy, has argued that Sustainable Urban Mobility Plans should account for reduced health and environmental costs alongside conventional transport metrics.

  Critiques of active transport policy run in several directions. A significant concern is safety: increased cycling and walking exposure raises the statistical likelihood of serious injuries and deaths, particularly in collisions with motor vehicles. Active mobility can also be more time-consuming than driving, and hills, climate, and distance create practical barriers that infrastructure alone cannot eliminate. A pointed criticism holds that converting traffic lanes to bicycle use makes travel harder for commuters who have no viable alternative to a car.

  The Netherlands stands as the most cited example of active mobility at national scale. More than 40% of urban commuting in the Netherlands involves active travel, supported by 35,000 kilometers of dedicated cycling paths and decades of government policy aligned with its flat topography and temperate climate. The Dutch government estimates roughly 1.3 bikes per person in the country. But the Netherlands also illustrates the safety costs of high cycling rates: about 20% of Dutch road accident fatalities are cyclists, with more than 100 cyclists dying each year. The Ministry of Industry and Water Management's policy efforts appear to have contributed to a declining mortality rate, which fell more than 30% between 2007 and 2016.

  Singapore's Land Transport Authority has taken a different approach, integrating cycling with the city-state's Mass Rapid Transit network. Following a pilot in the neighborhood of Tampines, the Minister of Transport presented a National Cycling Plan in 2013 covering 190 kilometers of paths, thousands of bicycle parking racks, and cyclist education programs. Critics have argued the plan is too limited in scope, prioritizing off-road connectors such as the Park Connectors Network over infrastructure that would support everyday city commuting.

  In England, the government's 2020 Gear Change plan set out to make the country a great cycling nation. It introduced cycling and walking corridors, low-traffic neighborhoods, and school streets, accompanied by two billion pounds in funding announced in May 2020 for the following five years, along with a new inspectorate called Active Travel England. Scotland's approach has drawn sharper criticism: Cycling UK noted that the Scottish budget allocates just 100 million pounds for cycling and walking, equal to 3.3% of the transport budget, or the total cost of building three miles of the A9 dualling scheme.

  The United States presents a different picture. American pedestrians and cyclists face far greater mortality rates than their counterparts in most other countries, and researchers have cited those rates as a contributing factor to low active mobility uptake. Federal programs through the US Department of Transportation's Livability Initiative, including the BUILD, INFRA, and TIFIA grant programs, have directed billions of dollars toward supportive infrastructure. The Fixing America's Surface Transportation act of 2015 expanded these programs with bipartisan support. Yet the numbers have moved in the wrong direction: the American Community Survey recorded 3.4% of Americans biking or walking to work in 2013, and that figure had slipped to 3.1% by 2018.

  Clutter on footpaths, such as road signs and electric vehicle charging points, may seem like minor inconveniences. For disabled people trying to walk on city streets, they can be the difference between an accessible journey and an impossible one. Uneven or steep surfaces, missing dropped kerbs, absent tactile paving, no places to stop and rest, and shared space with motor vehicles each function as barriers that compound one another. For disabled people who wish to cycle, narrow lanes, infrastructure requiring dismounting, physical access barriers, and inadequate cycle parking create a separate set of obstacles. Some individuals face medical barriers to active travel that no amount of infrastructure redesign can remove, and policy must account for continued access to motor vehicles for those people.

  Gender shapes active mobility in measurable ways. In London, 54% of journeys completed entirely on foot are made by women. Internationally, research across multiple cities has found that women walk more than men and use public transport at higher rates, while men have greater access to private cars. Design that prioritizes motor vehicles therefore disproportionately benefits men. Women are more likely to be trip chaining, linking multiple errands in a single journey, a pattern that favors cars. They are also more likely to be traveling with children, carrying shopping, or accompanying elderly companions, all of which shape what transport options feel practical. Road safety and the risk of male violence are both cited in research as factors that influence women's travel choices. A Sustrans report in the UK found little evidence that women participate meaningfully in transport policy and planning decisions. In Scotland, women hold only 6.25% of senior posts in transport bodies.
