Speed awareness has proven to be effective in reducing driver speed in many areas where these systems have been placed including school zones, residential neighborhoods, as well as random police selected locations. Telegra has developed speed awareness systems that can be manufactured to your specifications,
which are reliable and combine most advanced technology of Telegra’s LED Displays, speed measurement and vehicle classification technology.

Speed Displays are radar or other speed measurement device–activated signs, that dynamically display approaching vehicle speeds while at the same time they can count and classify passed vehicles in 5 classes. Standard Telegra’s Speed Display comprises two CE marked radar detectors:
· one, firing frontally, used for speed measurement of incoming vehicles at a distance of up to 250m
· other, firing laterally, used for counting, speed measurement and classification of each passed vehicle

Gathered information is continuously stored in non–volatile memory inside Speed Display. Memory is sufficient for storing more than 100 000 measurements.
Information (both current and historical) can be obtained through two interfaces, using common web browser:
· GSM/GPRS modem
· Bluetooth interface

Incoming vehicle speed can be displayed in user defined color, both steady and blinking. Multiple thresholds for blinking and change of color are adjustable. Blinking frequency is also adjustable. Refresh rate of the displayed speed can be adjusted in intervals ranging from 200ms to 5s.

Traffic safety and measurement is now available through Telegra’s LED Matrix Speed Display!
