SmartSensor 105

density function estimation represents the probability

that a vehicle will be located at any range.

The RVSD auto-conguration process shall dene all lanes

within the detectable area of the RVSD, up to the maxi-

mum number of lanes, during free-ow conditions; when

at least 50% of a sedan is visible above any barriers; when

the rate of trac ow is similar in all lanes; when at least 25

cars pass in each lane during conguration time; and there

are less than 10% lane-changing vehicles.

12.2 Manual Conguration. The auto-conguration

method shall not prohibit the ability of the user to manu-

ally adjust the RVSD conguration.

The RVSD shall support the conguring of lanes or detec-

tion zones in 2.5-ft. (0.8-m) increments.

When lanes have variable widths or have variable spacing (e.g.

gore between lanes), precise resolution is necessary.

12.3 Windows-based Software. The RVSD shall include

graphical user interface software that displays all cong-

ured lanes and the current trac paern using a graphi-

cal trac history representing at least the last 1.5 seconds

of detected trac.

A visual representation of trac paerns allows an installer to

quickly associate specic detections with corresponding vehicles,

and it facilitates verication of RVSD performance.

The graphical interface shall operate on Windows 2000,

Windows XP and Windows Vista.

The software shall support the following functionality:

● Automatically find the correct baud rate

● Automatically find the correct serial communication

port

● Operate over a TCP/IP connection

● Support dial-up modem connectivity

● Give the operator the ability to save/back up the RVSD

configuration to a file or load/restore the RVSD con-

figuration from a file

13.0 Operating Conditions. The RVSD shall maintain ac-

curate performance in all weather conditions, including rain,

freezing rain, snow, wind, dust, fog and changes in tempera-

ture and light, including direct light on sensor at dawn and

dusk.

RVSD operation shall continue in snow or in rain up to 4 in.

(10.2 cm) per hour.

The RVSD shall be capable of continuous operation over an

ambient temperature range of -40°F to 165.2°F (-40°C to 74°C).

The RVSD shall be capable of continuous operation over a rela-

tive humidity range of 5% to 95% (non-condensing).

14.0 Testing.

14.1 FCC. Each RVSD shall be certied by the Federal

Communications Commission (FCC) under CFR 47, Part

15, section 15.245 or 15.249 as an intentional radiator.

The FCC certication shall be displayed on an external

label on each RVSD according to the rules set forth by the

FCC.

The RVSD shall comply with FCC regulations under all

specied operating conditions and over the expected life

of the RVSD.

14.2 NEMA TS2-1998 Testing. The RVSD shall comply

with the applicable standards stated in the NEMA TS2-

1998 Standard. Third party test results shall be made

available for each of the following tests:

● Shock pulses of 10g, 11 ms half sine wave

● Vibration of 0.5 Grms up to 30 Hz

● 300 V positive/negative pulses applied at one pulse per

second at minimum and maximum DC supply voltage

● Cold temperature storage at -49°F (-45°C) for 24 hours

● High temperature storage at 185°F (85°C) for 24 hours

● Low temp, low DC supply voltage at -29.2°F (-34°C) and

10.8 VDC

● Low temp, high DC supply voltage at -29.2°F (-34°C) and

26.5 VDC

● High temp, high DC supply voltage at 165.2°F (74°C)

and 26.5 VDC

● High temp, low DC supply voltage at 165.2°F (74°C) and

10.8 VDC

15.0 Manufacturing. The RVSD shall be manufactured and

assembled in the U.S.A.

The internal electronics of the RVSD shall utilize automation

for surface mount and wave solder assembly, and shall comply

with the requirements set forth in IPC-A-610C Class 3, Accept-

ability of Electronic Assemblies.

The RVSD shall undergo a rigorous sequence of operational

testing to ensure product functionality and reliability. Testing

shall include the following:

● Functionality testing of all internal sub-assemblies

● Unit level burn-in testing of duration 48 hours or

greater

● Final unit functionality testing prior to shipment

Test results and all associated data for the above testing shall

be provided for each purchased RVSD by serial number, upon

request.
