Roundabout
Roundabouts are similar to traffic circles, requiring traffic to circulate around a center island. However, roundabouts are larger than traffic circles and are used on high volume streets to channel approaching traffic. Traffic Logix SuperFlex curbing can be used to create roundabouts.
Chicane
Chicanes are curb extensions that alternate from one side of the street to the other, forming S-shaped curves. By preventing drivers from taking a straight line through the street, chicanes slow vehicle speed. Traffic Logix SuperFlex curbing can be used to create chicanes.
Neckdown
Neckdowns are curb extensions at intersections that reduce roadway width to achieve speed reduction. Traffic Logix SuperFlex curbing can be used to create neckdowns.
Chokers
Chokers are curb extensions at midblock that narrow a street by widening the sidewalk. Traffic Logix SuperFlex curbing can be used to create chokers.

- Chalk
- Measuring tape
- Heavy duty hammer drill
- Drill bits carbide tip, At least two 9/16? dia., 10-12? long
- Hammer
- Sledge hammer (for final adjustment)
- 11/16? drive socket with an extension and power tool
- Street broom
- Utility knife
- Long rope or cord
- Crow bars, gooseneck wrecking bars
- Portable blower for cleaning installation holes
- Gloves, safety glasses, Traffic cones, drums or barricades for securing the site
- 2-4 installers (depending on the solution installed)

The first step is to remove any debris off of the roadway where the rubber circle is going to be installed.
Place one end of the rope or cord on the ?X? and the other end on the future perimeter of the circle. Keeping one end of the rope on the ?X? and holding onto the other end of the rope make a circle by marking several locations as you go around. This is a good time to check and make sure the circle is the size that you want it to be.

The next step would be to anchor one piece of our Super Flex red curb on the painted line. Place one end of the rubber curb on the line and drill a hole through one of the three holes found in the rubber curbing. The hole should be approx. 4? deep. Using an air compressor blow out the debris and insert a plastic anchor. Using the anchor installation tool install the plastic anchor through the curbing and into the asphalte.

Install a bolt and washer into the plastic anchor and tighten the bolt. Repeat this process until all of the rubber curbing have been installed.
Sometimes it?s necessary to cut the last piece or two of the red curb in order to get the right fit of your circle.

Some cities have added bricks or asphalt in the center of the circle to beautify the neighborhood as well as to support the vehicles which may inadvertently drive over the circle.

- From a safety point of view, steel toe boots and safety gloves are required.
- Make sure that the units are tight and well aligned before moving from one step to another.
- Make sure the holes are clear of dust and debris before installing the anchors
- Remember that all of the bolts need to be installed for the warranty to be in affect.
- Traffic Calming devices must be removed in the fall prior to the arrival of snow and installed in the spring after the last snow storm.
- Quarterly inspections should be made of each traffic calming device.
In accordance with ITE standards appropriate traffic signs should be installed with each traffic calming device.

Rubber- Traffic Logix SuperFlex curbing is made from flexible virgin rubber. Rubber is lighter and easier to work with than asphalt and concrete, significantly minimizing the number of hours that need to be invested to install the solutions. Rubber pieces can be pulled up and moved without being destroyed. This is convenient for municipalities that want to institute temporary measures to test an area and is also a safety measure so that products can be stored during the winter to prevent snow plow damage. Unlike concrete and asphalt which necessitate frequent and high cost replacement, rubber products are long lasting and cost-efficient. In addition to long term benefits, rubber products offer a quick, easy way to install solutions when timing is key. |

Easy installation- Traffic Logix Curb Extensions/Medians are simple to install. The curb is made so that it can be removed and relocated to an alternate street when needed. This feature is beneficial when a municipality would like to test a number of streets and measure the product’s effectiveness under different circumstances. |
| |
|
|
Reflective Tape- Traffic Logix uses a highly reflective tape on its rubber curbing. This tape is a safety feature to ensure that drivers can clearly see the curb both during the daytime and at night. Traffic Logix uses this tape on its products instead of paint since paint often fades away within months and the reflective tape can last for several years. Tape is available in several color choices. Highly reflective cat's eyes can be installed on any device for further enhanced visibility. |
| |
|
|
Environmentally Friendly Design- Traffic Logix Curb Extensions/Medians are made from recycled rubber tires. This ensures that while products address community health and safety needs, they are also friendly to the environment. |
