Slow cars, not ambulances

An innovative solution to emergency vehicle concerns on traffic calmed routes, speed cushions slow cars down without significantly affecting emergency response time. Designed as several small speed humps installed across the width of the road with spaces between them, the speed cushions slow cars down to between 15-20 mph as they ride over them. However, the wider axle of emergency vehicles such as fire trucks and ambulances allows them to straddle the cushions, driving over them without slowing down.

Puzzle piece design
Patented interlocking construction connects units like puzzle pieces, keeping them firmly in place.
Modular units allow you to customize your solution length, width, tape color, and choose striping or arrows. The opportunities are limitless.
Made of 100% recycled rubber, Traffic Logix speed cushions are an eco-conscious way to protect your streets. Grants are often available to municipalities who are buying recycled products.
Rubber speed cushions are long-lasting and removable for years of continuous use. Other solutions often require costly replacements while the Traffic Logix cushion units can simply be removed and reinstalled as necessary.
With a choice of yellow or white highway tape embedded into each unit, the speed cushions are highly visible, even at night or in poor lighting conditions
Prefabricated units offer consistency at all locations, an important factor for motorist acceptance and ease of use. Unlike concrete and asphalt, rubber units maintain their shape over time and do not contract with heat or vehicle pressure.
Traffic Logix speed cushions are quick and easy to install by connecting the units and securing them to the road with anchors and bolts. Traffic Logix units are smaller than the industry standard for easier installation. No road closures or skilled laborers are necessary.
The speed cushions can be removed for road resurfacing, snow plows, or to test the products at numerous locations. Unlike asphalt and concrete which must be destroyed during removal, the rubber cushions can simply be removed and reinstalled.
The Traffic Logix speed cushions are maintenance free and built to resist temperature fluctuations, inclement weather conditions, and ongoing vehicle traffic.

- Physical properties:
- tensile strength: minimum 500 psi
- shore hardness 70A
- specific gravity 1.1
- Marking: Rubber modules are available in black or black with yellow reflective tape or black with white reflective tape
- Measuring tape
- Impact or hammer drills, we recommend that you have two heavy duty hammer drills (Preferrably spline drills)
- High speed drills, we recommend that you have two electric drills
- Drill bits carbide tip, At least two 9/16" dia., 10-12" long
- 3lb Hammer
- 10lb Sledge hammer (for final adjustment)
- 11/16" drive socket with a12" extension
- Street broom
- Utility knife or a hack saw (used for trimming the rubber as needed)
- Crow bars, gooseneck wrecking bars
- Portable air compressor able to maintain 120psi (used to blow out the debris after the holes are drilled)
- Generator and extension cords to run all four drills
- One 24" 2"X4" piece of wood. This is used to knock the panels in place.
- Appropriate signage in accordance to ITE's State of the Practice on Traffic Calming as well as ITE's Manual on Uniformed Traffic Control Devices (MUTCD)
- Clean the surrounding installation area by using the street broom.
- Measure the width of the road and determine the appropriate spacing for the speed cushions. The spacing shouldn’t be more than four feet apart.
- Using the Chalk line mark a line parallel to the curb where the first speed cushion is going to be installed and then mark a line that is perpendicular to the curb. Use these lines to square up your traffic calming device.
- Identify and separate the pieces that run parallel to the curb for both sides of the device..
- Assemble and position the first speed cushion.. Make sure that all of the tongues are facing out towards the center of the device. Use the tongue and groove system to ensure the units interlocked properly as shown below.
- Drill 9/16” diameter holes into the asphalt, through the existing holes of the first row using the hammer drill. The holes should be 3 1/2” to 4” deep in order to accommodate the plastic shields which are 3” long.
- Use an air compressor remove all of the debris from the holes are clear of dust and debris.
- Insert plastic anchors into the holes and install them securely into the asphalt surface.
- Using the high speed drill insert the bolts and washer into the plastic anchor. Ensure that the bolts are snug but do not over tighten.
- Once the first row has been bolted to the ground you can begin assembling the next row of panels and using a 10 lb sledge hammer knock the row snug to the first row. Continue assembling all of the pieces to make one complete speed cushion.
- Please note that Traffic Logix recommends installing speed cushions on roads where the maximum grade is 8% or less.
- Steel toe boots and safety gloves should be used during installation.
- 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.
