Highway construction work has increased each year steadily, along with concern for the safety and well-being of workers, pedestrians, and possible vehicle collisions. Road barricades are important tools to help protect workers by controlling the flow of traffic in work zones, as well as in many other situations where safety involves ingress and egress of vehicles and people.

There are many types of traffic barriers that may be used, the most basic and familiar being the A-Frame or parade barricade, which resembles a wooden sawhorse with a brightly painted top rail.
These road or traffic barriers are a variety of barriers that can be fitted with reflective or flashing lights and can be used to block road construction, excavation, crowd control, and other safety-related purposes. Regardless of the differences, they all serve the same critical purpose &#; to help control the flow of traffic and protect workers.
Road barricades, also known as traffic or safety barriers, are used to control the flow of vehicular or pedestrian traffic in a specified area. They are used at construction sites, accident scenes, as roadblocks, at school zones, concerts, and in a variety of other crowd control situations for temporary traffic control. There are many different types of road barriers in varying sizes, weights, and strengths, and it is important to choose the variety of barriers so that it can successfully perform the job required. Always be sure your devices are certified by MASH or NCHRP 350 compliant for crash tests.
In its simplest terms, a traffic barricade is a portable or fixed system having from one to three rails with proper marking and is used to control road traffic by closing, limiting, or diverting oncoming traffic from another area.
There are generally three types of barricades, called Type I, Type II, and Type III. They are commonly used for road detours and closings where vehicles are present. However, each variety of barricades has its own distinct advantages and was designed for a particular purpose. Therefore, selecting the right one for your individual needs should be carefully considered to ensure maximum safety and efficacy as well as compliant to crash testing and MUTCD requirements.
Folding street barricades are referred to as A-frame barricades, which can cause confusion as the same term is often applied to Style I and Style II barriers. All folding traffic barricades are collapsible and fold like a sandwich board, so they compactly, transfer easily, and if struck by a vehicle, they collapse easily. When they&#;re open, they make an &#;A&#; shape when viewed from the side.
Let&#;s look at each of them in a little more detail.
You will often see traffic barricades referred to as &#;Type I&#; or &#;Type II.&#; This term can apply to different styles of barriers, but what it specifically denotes is the number of reflective panels the barricade contains.
A Type I style folding barricade is so named because it has only one reflective panel or rail. Typically, it is at least 24 inches wide with orange and white stripes alternating at a 45-degree angle. Sometimes a second non-reflective rail is added to help give it a more stable base of support. Type I is also known as a waffle-board barrier because it resembles a sawhorse that can be folded flat. A Style I barrier indicates sheeting is present on the top board. While this variety is also considered an A-frame barricade, it is taller than the basic sawhorse A-frame and can be made of wood or plastic.
They are meant to collapse easily on impact so that they do not become a flying projectile that could harm other vehicles or pedestrians. Additionally, the stack-able nature of these barriers means that many of them can be transported and deployed quickly and easily to a work zone or construction area. They can also be taken down quickly and stored when not in use without taking up a huge amount of room. Style I Barricades are often used for pedestrian traffic control or on low-speed roads.
Just like Type I, a Type II barricade is lightweight and can be folded flat. It should also collapse easily upon impact.
It differs from Style I in that it has two reflective rails instead of one, with alternating orange and white stripes. Because the bottom portion of the barricade is also a reflective surface, these barricades generally offer better visibility at night than the Style I barriers. Therefore, Type II barriers are recommended for use on expressways or other higher speed roads.
Style III barricades are larger and have three reflective panels with alternating orange and white stripes. They are at least 4 feet wide, or larger, and are most often used for road closings because of their size and visibility. You can see this style of barrier positioned across roadways for detours, road closings, around heavy equipment, and for other types of traffic control.
Like Style I and Style II barricades, the Type III name refers to the number of reflective panels; in this case, three. However, unlike Type I and II, the Style III category of road barrier refers to only one variety of barricade. This style consists of two uprights, made of either wood, plastic, or steel, with three reflective rails between them. Sheeting can be on one side or both, they are break-away and typically come with a 360-degree flashing light.
Type III barricades are usually larger and more prominent than folding or parade-style barricades, so they are typically used to block access when an entire roadway or path is closed.

Construction sites are a dangerous area, and this danger increases whenever a construction project takes place near an active roadway with traffic nearby. As construction projects increase and more drivers hit the road, the use of traffic barricades is more critical than ever before to maximize the safety of construction workers, pedestrians, and drivers. There are many different types of barricades to choose from, with every kind of traffic barricade helping to prevent or limit accidents in their own way. The main types of traffic barricades are grouped into the most common types of traffic barriers, including:The different types of barricades are used to ensure the right traffic control device is used in the right situations. Roadside projects or construction projects with pedestrians nearby require the correct type of traffic equipment to prevent and limit accidents on highways, roads, and even sidewalks. Let&#;s take a look at different types of traffic barriers that are often used on construction projects to ensure you use the right equipment for the correct situations! Pedestrian barricades are used by schools, parking garages, and outdoor events to control the flow of pedestrian traffic in a given area. These multi-purpose pedestrian barriers are designed for both inside and outside use, and each control barricade comes with interlocking connection points to create a continuous link. Pedestrian barriers come in highly visible colors so they can be seen at night and in different weather conditions. You can attach barricade flashers to your pedestrian barricades to improve visibility and safety in the immediate area. In addition to the traditional type of pedestrian barricades, you may also need other signage like:This type of control device should only be used in situations to prevent pedestrians from accessing dangerous areas, and they should not be used on active roadways or to direct oncoming traffic. Be sure to only use pedestrian barriers in situations where you need to control the flow of foot traffic, as they are not made to redirect vehicular traffic.Most pedestrian barriers are made out of lightweight and durable polyurethane plastic materials. Plastic pedestrian barricades are the crowd control device of choice because they are UV resistant, easy to move, and come in a modular design. These barriers are easy to deploy, and they have twisting feed at the bottom of each device so they can be set up and stored easily. Plastic barriers are a big time saver, so if you have limited staff or short on time, then these are an excellent choice for any situation where you need to control the flow of pedestrian traffic.Similar to other plastic pedestrian barriers, the Work Zone Manhole Safety Fence is ideal to wall off a manhole or other small area where work is taking place. The work safety gate kit is constructed from lightweight plastic that is lightweight for easy movement. The bright colored barriers collapse at the hinge points so you can position the safety barrier wherever needed quickly and easily. Cone bars are a simple and lightweight solution for parking lots, crowd control, and emergency situations. These control devices are a great choice to create a highly visible barrier between pedestrians and potential hazards in public places and job sites. Each cone bar uses a retractable design to extend to 10 feet long. This means that you can space out the needs of your control devices and create a continuous line of warning signals as needed. Unlike other traffic control devices, cone bars require the use of traffic cones to stand the cone bars up and stabilize the structure. Cone bars should not be used in areas with high-speed vehicles, and should only be used in areas where pedestrians need to be notified of hazardous conditions. Since these cone bars sit on traffic cones, they do not offer additional stability and can be removed easily.Traffic control devices of the most common type of barricade seen on construction sites and similar areas. These types of road barricades are used to control the flow of pedestrian traffic and vehicular traffic in specific regions near construction zones, school zones, and accident sites. Traffic control barriers are often used on busy roadways and where vehicles are traveling near pedestrians at a moderate to high speed. The most popular types of traffic barricades include:The reason that traffic barriers are the most common and popular choices on construction sites and other situations are because this type of control device can be modified as needed with attachable cone signs and cone lights to improve visibility and direct traffic. Not only are traffic barriers more functional than other devices, but they are also accessible to transport and store. Traffic barricades are best used in areas with slow vehicular traffic, and where pedestrians need to be warned of oncoming traffic. Let&#;s take a look at the most common traffic barricades that you can use and where you should use this type of traffic barrier. Traffic cones (also called construction cones and road cones) are a common sight on highways, active roadways, and construction sites because these devices are easy to deploy, simple to store, and adequate warning markers for pedestrians and drivers alike. Road cones are lightweight, stackable, and durable because they are made out of polyethylene plastic so they can withstand harsh weather conditions and direct sunlight for long periods of time. Traffic cones come in different shapes and sizes, and you should choose the type of traffic cone best suited for the specific situation, like:Since road cones can fall over with a large gust of wind, you may need to add cone weights to the bottom of a road cone to ensure it remains standing upright near oncoming traffic or during inclement weather. Jersey Water Barriers are a sturdy traffic blockade used to close off roadways and provide added protection between construction sites, pedestrians, and vehicular traffic. Water Jersey Barricades are made from lightweight and durable plastic materials, so deployment only requires one person to set up and dismantle the equipment. Unlike their concrete counterparts, Water-filled Jersey Barriers are easy to transport and store. Instead of requiring heavy moving equipment and a team of workers, these barriers are ideal for short-term projects. There are other types of water-filled barriers that you can use to help in specific situations. The most common water-filled barriers include:Reflective traffic barrels are similar to traffic cones, but these channelizer drums have a broader base and feature more reflective surfaces for improved stability and visibility. Each traffic control barrel comes with handles for easy carrying, dragging, and lifting. You can enhance the strength of these traffic barrels by adding additional rubber weighted bases or sandbags to the base of the barrels if you are placing them near high-speed traffic or in areas that receive gusts of wind. Traffic drums are an excellent choice for any project because they are lightweight and stackable. This means that you can transport and store the traffic drums with ease, and you won&#;t need a large team of workers to deploy the devices in the field. Best of all, the highly visible traffic drums are durable, so you can use them for several years at a time without the need to replace them with normal use. Delineator Tubes and Delineator Posts come in a variety of colors and are used to alert pedestrians, drivers, and construction workers about dangerous environments. Delineators are commonly used in parking garages, parking lots, gas stations, and construction zones because they are visible at night and inclement weather. Delineators are made from lightweight materials, and they are resistant to UV light and can withstand everyday use for years at a time. These types of channelizing devices should be used in areas where vehicles drive below 50 MPH, so they should not be used on highways or other high-speed roadways. A-Frame Barricades are shaped like sawhorses used on workbenches. These traffic barriers use highly visible orange and white reflective patterns to warn pedestrian and vehicular traffic of dangerous environments. A-Frame Barricades are used for many applications on a construction site, school zone, and even for crowd control. The horizontal beam with reflective materials means that they are easier to see than traffic cones or other control devices. At the same time, since A-Frame barriers have a wide footprint, they are also sturdier than delineators or traffic barrels. Adding lights and mounting signs to your A-Frame Barrier is a great way to maximize the safety and functionality of the A-Frame Barrier. Look for durable plastic A-Frame Barricades if you need to block off roadways, sidewalks, or notify pedestrians about a dangerous area.Highway and city road construction work is quickly becoming a common sight on our roadways. As more roadway projects start each year, construction projects need to use a specific type of barricade to ensure the safety of workers and pedestrians while reducing the chances of accidents. Road Barriers are used to control the flow of pedestrians and vehicles, and while there are many different types of portable traffic barricades, there are three types of barricades called:These types of barricades are used for road detours and when closing a road to vehicles. Unlike other types of traffic barriers, road barriers are designed to be highly visible to oncoming traffic and tested for crashworthiness. Every kind of barricade is designated by the size and shape of the traffic control device, and each one has specific parameters for when and where it can be used. There are many types of barricades to choose from, and it&#;s essential that you select the correct barricade for your specific needs. Let&#;s take a look at the three main types of road barricades and when you should use each one!The Type I barricade has a single reflective panel, and this type of barricade is typically 24 inches wide with orange and white stripes. This type of barricade is also called the &#;waffle board barrier&#; because it looks like a sawhorse and a board stretching across the legs. Many project managers like the Type I barrier because it collapses easily and does not require additional tools to deploy in the field. Not only is the collapsible design great for storage and transportation, but this type of barricade is also designed this way to collapse when struck by a vehicle. Type II barricades look similar to Type I barricades since they both have A-Frame legs and a panel that stretches across the frame. However, the Type II barricade has two reflective rails instead of the single panel found on a Type I barricade. Since a Type II barricade has two reflective panels, this type of barrier is often used in high traffic areas and where vehicles travel at faster speeds. Due to the increased size and weight, this type of barricade can be used on expressways and high-speed roads. Type III barricades are the largest type of road barricade on the market. This type of barricade is engineered with at least three reflective panels. Unlike the other types of barricades, this type of road barricade is constructed from several standalone uprights with the reflective rails attached after installation. Due to their size and shape, the Type III barricades are larger and more prominent than Type I or Type II barricades and should be used to indicate closed roads and dead ends. Since this type of barricade is larger than the other types of barriers, you should deploy this type of barricade in high-speed and high traffic areas.
