Traffic Set-Up Examples
35 mph neighborhood speed limit
Set the “MS” (the radar detected Minimum Speed limit) at 5 mph, the
“SLOW” message at 35, “Flashing Speed” at 40mph, the “Red & Blues” at
50 and the Blanking Speed at 60. This is what will happen:
Oncoming
vehicles speeds will be shown on the sign traveling from 5 to 34 MPH. If
the vehicle is traveling 35 to 39, the SLOW message will flash. Between 41
and 49, their speed will be displayed while flashing. Over 50MPH, the
display will show the Red & Blue flashing lights pattern. At 60 and above,
the display is blank. As the vehicle slows, the appropriate “Violator Alert”
will show for their speed until they reach 34 MPH where their speed is
displayed normally.
School Zones
Set the “MS” (the radar detected Minimum Speed limit) at 15 mph (so
drivers in a school zone obeying the speed limit are not distracted), the
“Flashing Speed” at 16mph and the “Blanking Speed” for 40mph. This is
what will happen: For speeds under 15 MPH, no speed will be displayed.
The display will flash the speed for vehicles traveling between 16 and 39
MPH. No speed will be displayed above 40 MPH.
7. READOUT RESULTS
The readings from the radar unit are filtered. The radar unit is very sensitive, so for
continuity of the oncoming driver, not every reading may be displayed. If there is a
difference between vehicle speeds of more than 3 miles per hour per second (extreme
acceleration or deceleration), the display will simply hold the last recorded speed for a
few seconds rather than jumping back and forth between speeds. A couple of
examples:
Example 1:
Example 2:
If a vehicle is traveling at 35mph and the car behind him is traveling
at 40mph, the sign will display the first vehicle at 35 until it passes.
The first vehicle’s speed will show for 1-1/2 seconds after it passes,
so the radar can establish and display vehicle two’s speed at
40mph.
If a vehicle accelerates towards the sign from a stop at greater than
3 miles per hour per second, no speed will be displayed. If a vehicle
accelerates at 3 miles per hour per second or less, the sign will
display the speed as it increases.
