Radar Speed Signs

Radar speed signs display the speed of oncoming vehicles using highly visible LEDs to make motorists aware when they are driving at unsafe speeds. They are a traffic calming solution that has been proven to slow traffic down and is ideal for use on local roads or in school zones. Traffic Logix speed signs use a unique patented optical system that provides optimal visibility, low power consumption, and innovative vandal resistance.

General description:

Speed Humps and Speed Tables of various dimensions are constructed using interlocking modules (US patent pending 12633-23USPR). The standard foot print dimensions of each module are 18” by 42”. The weight of the various modules is between 50 and 100 lbs. Each unit is bolted to a paved road surface using six lag bolts 3/8” dia. through a plastic shield installed in the road surface. The Traffic Logix proprietary two directional tongue and grove interlocking system provides additional connection between the modules and increases stability of the speed hump or speed table.

Dimensions of the modules:

- width 18” (+/- 1/16”)
- length 42” (+/- 1/8”)
- thickness 3” (+/- 1/8”)

Dimensions of the Speed Humps/Tables:
(width and length of speed hump are adjustable)

- width from 7’ up, by 3.5’ increments
- length: according to a street width, from 6’ by 1.5’ increments
- height: 3” or 4”

Standard dimensions of the Speed Humps/Tables:

- width 7’, 14’, 21’
- length: according to a street width
- height: 3” or 4”

Entrance and exit gradient:

1:15

Side gradient:

1:3

Material:

Compression molded 100% recycled synthetic and natural rubber composite

Physical properties:

- tensile strength: minimum 500 psi
- shore hardness: minimum 70A
- specific gravity 1.1

Marking:

rubber modules are available in black or black with yellow reflective tape or black with white reflective tape

Installation method:

-	each module is affixed to the pavement with six zinc plated steel lag bolts 3/8” x 4”, plastic polypropylene shields and 3/8” zinc plated steel washers supplied with the modules
-	9/16” diameter holes are drilled through the holes in the modules into a paved road.
-	the plastic shields are installed in the mounting holes with the provided installation tool
-	the lag bolts are inserted into mounting holes and tightened (do not over tighten the bolts)

Installation tools:

-	chalk line, measuring tape, heavy duty hummer drill, 9/16” dia. by 10” long carbide tip drill bits, installation tool for plastic shields, 11/16” drive socket with a power tool, portable blower, utility knife, crow bars
-	installation tool for the plastic shields is supplied for the initial installation job only
-	additional bolts, shields, washers, and installation tools can be purchased from Traffic Logix

Warranty:

A two (2) year warranty is provided on all Speed Hump/Table components installed as per the manufacturer’s installation instructions.

Product Features

Uses high intensity patented optical technology for the most brilliant optics on the market
Maximizes LED life expectancy using a series of lenses to allow LEDs to operate at optimal brightness using only 30% of power supply
Non-glare self-cleaning optical design provides recognition from 1000 feet even in poor visibility conditions
Detects speeds of approaching vehicles from various distances with an adjustable radar system
Sign flashes to warn drivers who exceed designated threshold speed
Optional high intensity strobe provides aditional warning to motorists
Withstands extreme weather conditions
Built in K-band Radar
30” width by 42” height for optimal visibility without obstructing driver view
Innovative lens system keeps out rain and ensures that all inner components remain dry
Unique vandalism protection with LEDs located at the back of the sign unlike other signs where the LEDs protrude from the front
Internal memory counts passing vehicles and provides detailed feedback
Optical lens focuses light directly toward approaching vehicle while appearing dimmer to cars in other lanes to avoid motorist distraction
Two year warranty on all Traffic Logix radar speed signs, 10 year warranty on all sign LEDs
Sign can be powered via power grid or independently by solar panel and battery
Fully compliant with MUTCD standards

Radar Capabilities

Signs equipped with Houston Radar DR500S, which provides the most accurate speed reading on the market

Read the full article about the radar comparison study here
Radar counts vehicles and vehicle speeds internally unlike most signs which do so externally
Unlike other signs, can count multiple vehicles going by simultaneously and the individual speed of each vehicle for more accurate speed data
Uses four times less operating power than other radar technology

Optional Data Collection and Software

Built in traffic counter collects and saves data on passing vehicles
Utilizes Bluetooth for fast and secure wireless data download
User friendly software interface allows for easy setup, programming, assessment, and monitoring of signs
Features real time clock and stores vehicle speed data in 17 speed categories including time stamp of measurement period
Provides calculations such as 85% percentile, minimum, maximum, and average speeds.
Can store data from 15 days at 15 minute data collection periods to 60 days at 1 hour collection periods
