Cycling infrastructure

People use many paths to ride bikes.

Some paths are just painted lines on the road. Other paths have walls to keep riders safe.

These paths help people go places easily. Some paths are even made from old train tracks.

Good paths make riding much safer for everyone. More paths mean more people will ride bikes.

Cycling infrastructure is any part of a city built for bikes.

This includes many different types of paths and lanes. Some lanes use paint to show where to ride. These are called bike lanes.

Other paths use barriers to keep bikes away from cars. These are called cycle tracks.

These tracks are often safer for riders.

Some paths are not for cars at all. A cycle path is a way for bikes that is far from a main road.

There are also shared use paths. These are paths for both walkers and riders.

Some of these paths are greenways. These are trails built on old land, like old train tracks.

Cities also use special tools to help riders. They use bike racks to park bikes. They also use special traffic signals.

Good design helps people move fast and easy. When there are more good paths, more people choose to ride bikes.

Cycling infrastructure is everything built to help people ride bicycles.

It includes paths, lanes, and even special signs or parking racks. Some of these routes are built just for bikes. Others are parts of roads that cars also use. Having good paths makes riding much safer and easier. When a city has many good routes, more people choose to travel by bike.

There are many ways to design these paths. Some use only paint on the road to mark a bike lane.

Other paths use physical barriers like bollards or curbs to stay separate from cars. These are called cycle tracks.

Some paths are shared with people walking. These are often called greenways or multi-use paths.

Some streets are even made for bikes first, like a bicycle boulevard. These streets slow down cars to help riders move through easily.

The history of these paths has changed over time. It started shortly after the bike boom of the 1880s.

Back then, people built the first short stretches of special paths. Later, cars became very common in the mid-20th century. This caused many people to stop using bikes for travel. However, cycling began to make a comeback starting in the 1970s. Now, many cities are building new ways to help riders.

Different places have different rules and measurements for their paths. In the Netherlands, a path should be at least 2 meters wide.

If more than 150 bikes use it every hour, it should be 2.5 meters wide. Cities like Utrecht and 's-Hertogenbosch also use this 2-meter rule. In North America, cities like Montreal and Davis, California, were early leaders.

They have used paths with barriers for many decades. Other big cities like New York and San Francisco are adding them now.

You might see these ideas in your own town. Many paths are built on old land, like disused railways.

These paths can act like parks or paths for wildlife. You might also see special lights at crossings.

These signals help riders know when it is safe to go. Just like a sidewalk is for walking, these paths create a special space for moving. They help connect where people live to where they need to go.

Cycling infrastructure refers to all the physical systems and facilities designed for bicycle travel.

This includes specialized paths, lanes, and routes that make riding more efficient or safer. It also encompasses amenities like bike racks for parking, shelters, and service centers. Specialized traffic signals and signs are also vital parts of the system. The presence of high-quality infrastructure directly influences how many people choose to travel by bicycle.

When cities build dense, interconnected networks, they provide direct and convenient routes for commuters.

Infrastructure can be categorized by how it separates cyclists from other users. Some routes are separated from motor traffic by physical constraints like barriers, bollards, or even parking. These are often called cycle tracks or bicycle trails. Other designs use only painted markings on the road to define a space. These are known as bike lanes or buffered bike lanes. There are also lanes that allow cyclists to travel against the flow of a one-way street, called contraflow bike lanes.

Some infrastructure is designed for shared use between different types of travelers. A shared use path, or multi-use path in North America, is dedicated to both pedestrians and cyclists. Within these, greenways are often built along strips of undeveloped land for recreation or environmental protection.

Some streets are optimized specifically for bicycles while still allowing local motor vehicles. These are called bicycle boulevards or cycle streets. In these areas, the design discourages through-traffic from cars to give priority to cyclists. Another option is the sharrow, which is a road marking indicating a preferred position for cyclists when a dedicated lane is unavailable.

The history of these systems shows a significant shift in how cities prioritize movement. The development of dedicated infrastructure began shortly after the bicycle boom of the 1880s. During this time, the first short stretches of dedicated paths were constructed. However, the rise of the automobile in the mid-20th century caused a decline in cycling as a primary means of transport. This trend changed in the 1970s when cycling began a significant comeback.

Today, many urban planners work to rebuild these networks to manage modern traffic.

Safety is a primary goal of modern cycling design, particularly at complex junctions. On major roads, segregated cycle tracks generally offer better safety than cycling directly in traffic. However, intersections can be dangerous places due to collisions between turning motorists and cyclists. To solve this, engineers use designs like cycle path deflection or protected intersections.

Protected intersections follow models, such as those from the Netherlands, to preserve physical separation. At multi-lane roundabouts, safety can be compromised unless separated cycle tracks are installed to protect the riders.

Different regions follow specific technical standards and measurements for their infrastructure. In the Netherlands, the Tekenen voor de fiets design manual recommends a minimum width of 2 meters for paths. If a path must accommodate more than 150 bicycles per hour, the width should increase to 2.5 meters. Cities like Utrecht and 's-Hertogenbosch also require a 2-meter minimum for new lanes. In North America, cities like Montreal and Davis, California, were early adopters of segregated facilities with barriers.

Other major cities like New York, San Francisco, and Vancouver are now increasingly adopting these segregated models.

There is ongoing debate among planners regarding the best way to implement these changes. Some critics argue that infrastructure designs from one country, like the Netherlands, may not work perfectly in every other context. Others worry that dedicated lanes might increase urban air pollution. Some planners advocate for a complete network built in a single phase rather than a piecemeal approach. Conversely, proponents argue that well-implemented lanes effectively relieve both congestion and air pollution.

Research into "road diets," which restrict motor traffic lanes to make room for bikes, suggests that crash frequencies can drop by 6% after installation.
