The Street Dynamics Speed Awareness Monitor (SAM) Radar Speed Sign
The Speed Awareness Monitor (SAM) radar speed sign is a 24/7 traffic calming presence built on a rugged, dependable trailer. Despite its compact size, the SAM is legible from 1,000’ (305 m) away and able to operate continuously when fitted with an optional solar panel. It also features changeable SPEED LIMIT numbers, so you can deploy your SAM anywhere without the need to purchase a whole collection of individual SPEED LIMIT signs.
Small Footprint, Big Impact
Don’t let the SAM’s size fool you- its small size allows it to be easily positioned anywhere you need to calm traffic, and its bright 18” amber LED characters communicate drivers’ speed up to 1,000’ (305 m) away. The optional programmable LED violator Alert warns motorists by flashing red/blue strobes when they have exceeded your pre-set speed threshold.
The SAM radar speed sign is equipped with the same radar technology that is used by over 85% of State Police Agencies in the United States, so you can count on it to be accurate and durable. It offers amazing range, sensitivity, and vehicle tracking.
Greater Visibility + Longer Battery Life
The SAM radar speed trailer is fitted with our exceptionally bright and clear proprietary LED Lamp Matrix and LED Pulse Width Modulation technology. The LED Lamp Matrix concentrates and focuses the LED’s light, allowing the motorist to see the sign at a greater distance and, thus, act on the speed warning quicker.
LED Pulse Width Modulation is also incredibly efficient, significantly reducing the drain on batteries and allowing the LEDs to remain at a consistent brightness throughout the battery’s entire discharge cycle.
In addition to measuring speeds, the radar unit in the SAM speed trailer can be used to collect and store traffic data including vehicle speeds, vehicle classification, 85th percentile data, and more. This data can then be downloaded into the Easy Analyst software to create clear, colorful reports, charts, and graphics that you can present to your department, city council, and infrastructure managers.
The SAM speed sign can run for up to 18 days of continuous operation using its 4D Deep-cycle 12-volt battery. Add an optional top-mount solar panel to run your sign indefinitely. The solar panel needs only 2.5 hours of bright sunlight to recharge a full day’s worth of battery power.
The SAM is easy to use with its dedicated hand-held controller. Get complete programming and diagnostic functions right in the palm of your hand.
