Advantages and disadvantages of concrete lane dividers!

People cycle on their bikes to feel the tranquillity of the environment and remain young. For many people, it’s a hobby, and they can’t just live without it. Similarly, some people purchase the latest new bike because they are passionate and consider cycling as their sport.

No matter how important cycling is for you, bicycle safety is an integral aspect, or else there can be accidents. Many states are now recognizing the benefits of cycling, and they encourage cycling enthusiasts by implementing necessary safety measures.

Cycle lane dividers are one of the common safety tools for bicyclists. However, lane dividers differ because they can be manufactured in different types and from different materials. Concrete is one conventional lane separator material that can create protected bike lanes.

Let’s see what their specifications are and why they are special.

Do you want to know more about this topic? We also have an article talking about different types of lane dividers.

Pros of concrete lane dividers

Concrete is the predominant material for creating sidewalks and crosswalks in city streets, which increases pedestrians’ safety. It can be used to create cycle tracks, bike routes, and separate lanes for a two-way road.

Here are some of the special advantages that make it unique:

  • They are strong and have tensile strength. You cannot shake them easily, and once installed, these lane dividers will not budge from their position. Most cyclists will be safe with a concrete lane divider because this will be a permanent solution.
    Therefore, concrete bikeways are durable and will not wear out soon.
  • Most concrete curbs have rebars – steel rods are reinforced within them. As a result, their strength increases, and they can withstand repetitive collisions and impact by a vehicle.
    Therefore, cyclists will ride their bikes without any worries of crashes because these cemented permanent lane dividers will create a no-gap bike lane.
  • Some concrete dividers are made from huge blocks, which are also stable in the long term. Therefore, such blocks will fixate on a single position and not move easily.
  • Concrete lane dividers will remain the same and will not twist over time. Therefore, they are a perfect long-term solution that will free your mind from worries for a long time to come.
  • You can even paint your concrete lane dividers with bright colours. That will increase the visibility of lane dividers in night or dark areas like underground passages and low-light parking spaces.

Cons of concrete lane dividers

While concrete lane dividers are known for their tensile strength and immense power, the same feature can pose a serious risk.

Following are some severe shortcomings that can make concrete lane dividers less attractive:

  • It’s true that they are strong and can create a permanent delineation for bike paths. However, the same concrete boulders can pose serious risks for other car traffic vehicles, causing heavy damage.
    Some cars can even experience rollovers after hitting these concrete lane dividers. Such a risk gets serious for emergency or big vehicles like buses, fire trucks, or ambulances because they can also skid and get in a severe accident.
  • Most companies can only paint concrete lane dividers in a single colour – grey. Some companies can get you customized paint, which can also wear out due to UV rays and vehicle collisions.
    It’ll take time to wear out, i.e., 5-6 years, but the colour is still not permanent. As a result, concrete lane dividers can be less reflective, and even bicyclists might not see them, leading to severe physical injuries.
  • They are not easy to install. Some concrete lane separators may require construction on roads that can be costly and take time to create a lane divider. Also, it may cause air and noise pollution, which is not environmentally friendly at all.
  • Concrete lane dividers are huge curbs, and they can take up a lot of space on the roads. As a result, they can reduce the width for cyclists to bike comfortably.

      Alternative material for lane dividers

      Concrete lane dividers are the most traditional method, and concrete is the first material that laid the foundation for traffic calming measures like speed bumps, speed cushions, and speed tables. However, other materials can also create cycle lane dividers.

      Some of them are as follows:

      • Rubber
      • Plastic

      Vulcanized rubber lane dividers are great options because rubber is strong and can last for a very long time. Vulcanisation gives rubber strength and removes its deformity, making it strong enough to withstand impact from passing vehicles.

      Plastic is the infamous material used to create lane dividers. The recycled plastic is soft and can withstand the impact of vehicles. They are also good at shock absorption and are a very cost-effective way to create cycle paths.

      However, they may get brittle in low temperatures, making them susceptible to breaking.

      Metal is an uncommon material for lane dividers. However, two-way rails and crossings are their most common applications, and they aren’t used much for lane dividers. They are useful for highways and fast roadways and may not work on city streets.

      Black and white lane dividers made of rubber and black and white lane dividers made of plastic to separate different lanes.

      Different shapes of concrete lane dividers

      Any shape that can create a separate bike lane for bicycles is a lane divider. Concrete lane dividers can exist in various shapes and designs.

      The following are some of them:

      • Concrete buttons
      • Rectangular concrete blocks
      • Concrete barriers
      • Blocks with guidepost

      A concrete button is a round circle concrete separator, which is quite small, extending up to 500 mm. Many of them are placed in series with gaps to create separate lanes for bicycle riders, reducing the chances of accidents in traffic lanes.

      Similarly, there are big rectangular concrete blocks that can extend more than 1,000 mm. These blocks are placed in series across a bike lane for delineation. Since they are massive heavy blocks, they are difficult to move and are stable.

      In many places, large concrete barriers are used for creating separate bike paths. These barriers are also high, up to several feet and can create a separate bike path. In such cases, other vehicles can’t even trespass in bike lanes because they can suffer huge damages from crashes.

      There are some rectangular blocks on a road that can incorporate a guidepost within them. They have a hole in the middle, which is specifically for guideposts that are several mm high, which makes spotting these concrete dividers easier.

      Alternative tools for delineation

      Concrete is indeed a useful tool for creating segregated bicycle lanes. However, there are other safety measures for bicycling activities.

      Some of them include the following:

      • Lane markings
      • Signages
      • Curbs, bollards, and bike box

      Painted lanes serve the common purpose of reducing traffic congestion. Road markings include creating pavement markings, dashed lanes, and buffered solid white lines. Solid white lines indicate that a person cannot cross their lane or there will be a penalty.

      Similarly, dashed and buffered lanes are ways to create visuals and lanes for cyclists.

      People must obey traffic signals and other essential traffic laws in any country. There are signages, including stop signs and speed limit signs. These signages can be used to create awareness about bike lanes in the area.

      Therefore, motorists will be careful while driving due to possible bike paths on the roads.

      Similarly, influencing the road infrastructure by reducing the lane width using curbs and bollards is also a good solution for bicycle safety. These bollards and curbs can be installed in series to indicate a separate cycle track.

      Furthermore, another way to make traffic lanes safer for cyclists is by using a bike box; these are green lanes that involve creating separate cycling tracks for cyclists on traffic signals. As a result, there are rare chances of accidents for cyclists at intersections and roundabouts.

      Walking and biking are essential activities that keep people fit. Therefore, there must be incentives to encourage cycling on the city streets. Many bikers conduct bicycle advocacy campaigns to facilitate the cycling culture and allow recreational cyclists to enjoy their cycling experience.

      Even MUTCD, Vision Zero, and the Department of Transportation are enacting measures across various jurisdictions to improve bicycle safety.

      Despite the shortcomings, concrete lane dividers are quite an amazing tool for creating separate bike lanes because they are permanent and will last for a lifetime.

      On the other hand, plastic and rubber lane dividers serve their purpose as well by creating effective bicycle routes.
