In various scenarios, the need to manage or divert traffic arises, whether for enhancing safety at a work zone, restricting vehicle access during events, or securing restricted locations.
Several methods are available to accomplish these tasks effectively. Users can choose from a range of traffic control options that effectively direct and stop vehicles in designated areas, depending on specific needs.
Quick Installation with Traffic Cones
Traffic cones are among the most accessible traffic control solutions. Their lightweight and portable design makes them suitable for temporary placement.

Durable enough to withstand harsh conditions, cones come in different sizes to redirect traffic or mark hazards, such as lane diversions or construction zones. Barrels are a larger alternative used to protect road workers, with options for added stability through water, sand, or cement filling. Their vibrant colors and reflective surfaces ensure visibility.
High-Security with Bollards
Bollards offer more robust traffic control solutions, designed typically for permanent installation to restrict traffic flow. Made from materials like cement or steel, these devices are ideal around pedestrian areas and buildings.
There are fixed and retractable bollards—the latter provides flexibility by retracting underground when not in use. Delta Scientific offers several bollard models to cater to varying security needs, including manual, hydraulic, and electromechanical options that can operate quickly to satisfy stringent security standards.
Enhanced Security with Wedge Barriers
Wedge barriers provide high-level security, particularly suited for embassies, military installations, and sensitive areas requiring strict access control.
These barriers, integrated into an underground base, employ hydraulic and electric systems to raise or lower a physical wedge across roadways, entirely obstructing traffic when elevated. When not active, they retract for an unobtrusive presence, with customizable materials and colors to blend seamlessly into their surroundings.
Adaptive Control with Signs and Signals
When flexibility is critical, traffic signs and signals offer adaptable solutions, providing visual guidance on speed limits, directions, and lane modifications.
These are optimal for traffic management in construction areas or when immediate, temporary lane closures are necessary. While effective for non-critical security needs, these signals require driver compliance and are more appropriate when alternate solutions or backups exist.
Moveable Barriers with Beam Barricades
Beam barricades serve as movable physical barriers, apt for directing traffic across spans from 10 to 30 feet. Depending on requirements, users can choose between manual, hydraulic, or electric operations, with beams designed to open either horizontally or vertically. Commonly used in parking facilities or locations with controlled access, they rest on buttresses flanking the roadway.
Speed Control with Pavement-Based Solutions
Speed bumps and humps are effective for enforcing speed reduction in travel lanes
Speed bumps and humps are effective for enforcing speed reduction in travel lanes. Positioned in parking lots or near gates, these raised pavement sections encourage slower vehicle movement.
Similar to rumble strips, which use textured surfaces, these solutions are cost-effective and durable, typically long-term unless markings require frequent repainting to maintain visibility.
Temporary Solutions with Portable Barriers
Portable barriers offer quick, visible traffic control with easy installation and high crash ratings, ideal for temporary security measures. Wedges or beams fitted on trailers represent common setups that a small crew can install within minutes.
Portable bollards also provide swift traffic management alternatives. Delta Scientific, as a pioneer in high-security traffic controls, presents a variety of barrier systems capable of withstanding impacts up to 50 MPH.
There are many situations where users may need to control or redirect traffic. It might be to increase safety in a work zone, keep vehicles from a specific area during an event, or limit access to a restricted location. Traffic controls allows users to accomplish this through one of several methods.
There are many different types of traffic controls. The following types of traffic controls can help direct, slop, and stop cars in designated areas. Learn more about each one, where they work best, and how to use them most effectively.
Quick installation in temporary locations
Traffic Cones - Cones are some of the simplest types of traffic control available. They are lightweight and portable, making them ideal for quick installation in temporary locations. Durable construction allows them to withstand harsh conditions.
Traffic cones come in various sizes. Common uses include redirecting traffic, such as into another lane, or marking road hazards. Barrels are larger and often used to protect workers performing road construction. Some can be filled with water, sand, or cement to stabilize them and provide reinforcement. Bright colours and reflective markings make them highly visible.
High-security barrier system
Bollards - Bollards are more substantial traffic control devices. They can be cement, steel, or other rigid materials. Most are installed in permanent locations to stop the flow of traffic. Bollards are ideal for installation around pedestrian areas and buildings.
There are two main types of bollards: fixed and retracting. The former stays in position, offering constant traffic control. If users need a more flexible solution, they can install retracting bollards. They go underground and rise as needed to provide an effective high-security barrier system. Delta Scientific offers several models of bollards, including manual, hydraulic, and electromechanical. Some models can raise and lower in seconds to meet the strictest security requirements.
Physical wedge barrier
Wedge Barriers - Wedge barriers offer high security for restricted-access areas. Embassies, military installations, and other sensitive facilities rely on this type of traffic control to enhance security. They are typically set into an underground foundation, which allows for raising and lowering the physical wedge barrier with hydraulic and electric mechanisms. When raised, the wedge spans the roadway or entrance, completely blocking traffic.
Because the barriers retract into the roadway, they are unobtrusive when not deployed. Different materials and colours can help them blend into the facilities.
Intermittent lane closures
Traffic Signs and Signals - Situations that call for traffic controls that are easy to change as needed may be better served with signs and traffic signals. These provide visual cues to drivers about speed, direction, and any lane changes. Users can also use them to stop traffic, such as when construction requires intermittent lane closures. Because signs and traffic signals require drivers to consciously comply with instructions, they are best suited for situations that do not require high security or where a backup is possible.
Moveable physical barrier
Beam Barricades - Beam barricades are excellent for situations that require a moveable physical barrier to direct traffic. They can cover openings ranging from 10 to 30 feet, with beams that open either horizontally or vertically. Users can choose from manual, hydraulic, and electric beams depending on their situation.
This type of traffic control uses a physical beam that rests on buttresses on either side of the opening or roadway. Beam barricades are commonly seen in parking areas or locations with restricted access.
Raised portions of pavement
Speed Bumps - Speed bumps are a type of traffic controls. Speed bumps and humps consist of raised portions of pavement within travel lanes. They encourage drivers to reduce their speed. Speed bumps are excellent when placed in parking areas or approach lanes to gates. Rumble strips are similar traffic control devices that use textured surfaces cut into the pavement.
Pavement-based traffic controls like speed bumps are inexpensive and easy to install. They are generally considered long-term solutions that last as long as the surrounding pavement. However, they are most visible and therefore effective when painted in a contrasting color, and you may need to touch up markings more frequently.
Portable barrier systems
Portable Barriers - There are many types of portable barrier systems. Most offer quick installation and high visibility. Some systems have extremely high crash ratings, making them ideal for temporary functions with restricted access.
Wedges or beams mounted on trailers are a common configuration. A crew of two people can generally set them up within 10 or 15 minutes, which allows for a quick solution for controlling traffic. Portable bollards are another option.
Delta Scientific is proud to be a pioneer manufacturer of high-security traffic controls. They offer several types of barrier systems designed to withstand up to 50 MPH impacts.
