In Porto Alegre in southern Brazil, thousands of cyclists held a demonstration calling for the creation of new bike lanes and improved road safety.
On July 6, a traffic accident occurred in London, UK. During the evening rush hour, a 20-year-old female cyclist was struck and killed by a large truck in East London. The bicycle the victim was riding was part of a government-funded public bike program, commonly known as “Boris Bikes”; the accident site, Cycle Superhighway 2 in London, is also a dedicated bicycle safety lane.
In 2010, then-London Mayor Boris Johnson launched an ambitious public bike project, planning to deploy 8,000 public bicycles across London and build corresponding dedicated and shared lanes to encourage more cycling, alleviate urban traffic congestion, and reduce serious vehicle emissions. The project was scheduled to run for five years with an initial investment of around £100 million. Just this March, Boris further proposed an overall plan including road network upgrades, aiming to make London “the most cyclable city,” with a ten-year timeline and an estimated investment of £900 million.
The accident on July 6 was undoubtedly a major setback for the “Boris Bikes” initiative, and it was the first fatality related to the Boris plan.
Safety Concerns in London’s Cycling Project
An article published by The Guardian stated that although the Boris project has been progressing well, “it was only a matter of time before an accident happened.” The public bike program encourages inexperienced riders and tourists unfamiliar with local roads to cycle through streets, but corresponding protective measures have not kept up. The infrastructure offers insufficient protection for cyclists, and there are also issues with driver behavior and awareness. Traffic accidents were bound to occur.
London’s bike lanes are mainly divided into three types. Most are dedicated bike lanes along main roads, usually separated from motor vehicle lanes by concrete barriers, though some are only marked with white lines. There are also recreational greenways that pass through parks and 12 planned Cycle Superhighways; in addition, in certain areas, cyclists can use bus lanes, where vehicles are subject to a default speed limit of 32 km/h.
London’s Cycle Superhighways are fast routes connecting the suburbs to the city center. The first was built in 2008, with a total of 12 planned. Currently, four (CS2, CS3, CS7, and CS8) have been completed, with all expected to be open by 2015. According to the construction plan, these superhighways should have prominent signage and road markings, maintain continuous paths at intersections (similar to Denmark), and include raised convex mirrors at junctions (learned from Switzerland) to reduce blind spots.
However, in reality, the completed bike superhighways in London are merely blue painted lines on the road, often without physical separation from motor vehicle lanes, making them easily occupied by cars.
The accident occurred at an intersection along Cycle Superhighway 2 (CS2). This particular intersection had previously been flagged as having safety concerns in an improvement report by London’s transport authority; however, proposals to redesign the junction were rejected for reasons that remain unclear, possibly due to funding issues. Earlier, the civic group “London Cycling Campaign” (LCC) had questioned the design and safety of the superhighway intersections. CS2 was opened in 2011 but, due to opposition during construction, did not reach its originally planned endpoint, instead ending abruptly at a roundabout. Its potential dangers have been criticized by many cycling blogs and advocacy groups.
Aside from route planning issues, around 50% of cycling accidents in London involve large trucks. According to news reports, the driver involved in this accident stopped at the scene, but police did not arrest him upon arrival. Media speculation suggests the cyclist may have been in the truck driver’s blind spot, thus reducing the driver’s subjective liability. In response, netizens joked in the comments, “It’s 2013, with cameras and screens everywhere—why do trucks on the road still have blind spots?”
In fact, large trucks can be equipped with inexpensive external devices to eliminate blind spots, but mandatory installation regulations have yet to be enacted. The media and public have criticized the government over this. Another point of dissatisfaction: why are large, slow-moving, and high-risk trucks allowed into central London during peak hours? Is the government considering regulations to restrict truck entry during rush hour?
Beyond hardware, driver awareness also plays a role. After the implementation of the Boris plan, many busy intersections in London gained “buffer zones”—white boxes painted with bicycle symbols reserved for cyclists waiting at red lights, positioned ahead of the motor vehicle stop line to prevent obscured sightlines and overlooked dangers. By law, motor vehicles are not allowed to enter these zones during red lights; violators face a £60 fine and three license points. However, this rule is not well respected, with vehicles frequently encroaching on buffer zones—even police cars have been photographed parked there. Last year, a minor accident occurred when a small truck driver invaded a buffer zone, leading to an argument with a cyclist. When the light turned green, the truck hit the bike. The cyclist was unharmed, but the bike was damaged. The driver was ultimately acquitted by a jury because he had started moving during a green light and “had no intention to harm.” This case reflects a broader issue: buffer zones are disrespected not only by drivers but also by many members of the public.
Earlier this month, London’s transport and police departments launched a campaign to distribute leaflets at busy intersections, educating drivers about the purpose and necessity of buffer zones. Cycling advocacy groups are also urging the government to strictly enforce the rules, ensuring these zones truly serve as safe areas.
Lessons from the “City of Two Wheels”
In today’s world of rapid population growth and severe metropolitan traffic congestion, cycling is undoubtedly an economical and eco-friendly mode of transport. But as the London case shows, building a cycling city is far more than just providing public bikes.
Take Copenhagen, the most famous “City of Two Wheels,” as an example. 36% of Copenhageners commute by bike, covering a total of 1.2 million kilometers daily. In the greater Copenhagen area, more people cycle than the total number of cyclists in the entire United States.
Copenhagen’s promotion of cycling dates back a century. As early as 1892, the city established its first dedicated bike lane. By 2010, Copenhagen had 397 kilometers of bike lanes—double the amount from the 1980s. It now plans to build an additional 70 kilometers of segregated bike paths and 67 kilometers of recreational greenways by 2026. Unlike most cities that adopt a “backstreet strategy” (placing bike lanes in quieter residential areas away from busy roads), many of Copenhagen’s bike lanes run almost parallel to main roads, offering cyclists more direct and time-saving routes. Bike lanes exist on both sides of the road and are one-way, separated from motor vehicle and pedestrian lanes by stone dividers. Legally, bike lanes must be at least 1.7 meters wide, but many are actually 2.2–2.5 meters, with the busiest sections reaching widths of 3–4 meters. Bike lanes are fully signed, truly enabling citizens to commute by bike and allowing visitors to cycle throughout the city.
In fact, in the 1960s, economic growth and a surge in motor vehicles caused Copenhagen’s cycling rate to plummet to a low of 10%. New roads were no longer designed with cyclists in mind, and traffic roundabouts replaced former bike lanes. However, the energy crisis quickly woke Copenhagen up, and the city returned to promoting cycling. A combination of government advocacy and oversight from civic groups created today’s cycling haven.
Since 1996, Copenhagen has published a biennial bicycle traffic report containing 10 indicators selected jointly by transport authorities and cyclists. In addition to standard metrics (such as infrastructure budgets, bike lane length, cycling rates, and accident statistics), the report also surveys frequent cyclists on aspects such as infrastructure quality, road maintenance, and perceived safety.
As the world’s most bike-friendly city, Copenhagen continues to strive for excellence. In 2011, the city released its latest cycling development strategy, aiming to raise the cycling rate to 50% by 2025, focusing on improvements in four areas: urban life, comfort, speed, and safety.
Copenhagen serves as a model for many cities. Cycling is also gaining momentum domestically, with cities like Beijing, Shanghai, Guangzhou, and Hangzhou implementing public bike programs and related infrastructure plans. The once-bicycle-dominated nation is getting back on two wheels—but the road ahead remains long.
