This is a brand new camera using no film just digital
cameras.
It uses not one, nor two, but three High Resolution
Digital Cameras linked to a strongbox on the side of the road.
Used for the monitoring of red light jumpers on
the red light phase of traffic lights and also for speed readings
during the green light phase.
Fig 1: Inductive loops in road.
How it works
Red Light Phase... working by multiple inductive loops (See fig 1) under the road they monitor the vehicles movement
over the target area, one target area for each lane and one camera
for each lane If the vehicle crosses the stop line then two digital
photographs are taken. Recorded on the photograph is the time,
date and phase time of the lights and distance comparison between
the times. This data is stored in the roadside strongbox for collection.
Fig 2: Piezo Strip (lane 2) in road.
Green Light Phase... working again by strips in the road
but this time they are Piezo strips set apart from each other (See fig 2) The vehicle speed is calculated from the time
taken to cross both strips, and then the third camera takes a
picture of the offending vehicle. The can also verify the speed
using the standard white markings on the road, (See fig 1) in this case white round dots. This part of the system only covered
lane 2 (the outside lane). Recorded on the photograph is the time,
date and phase time of the lights along with the speed. This data
is stored in the roadside strongbox for collection.
SpeedCurb™ Digital Speed Violation Enforcement
System.
The speed of vehicles passing through a monitored section
of carriageway is measured by either piezo sensors buried in
the road surface, laser or a built in radar module. All data
is protected against tampering through use of encryption and
data integrity codes embedded in the information. A built in
flash module permits operation at night. Operational parameters
including speed threshold and active time may be programmed
into the unit.
RedGuard™ Digital Red Light Violation Enforcement
System
The state of traffic signals are continuously monitored by
the system. If a vehicle is detected crossing the stop line
when the signals are red, then two wide-angle photographs and
one zoom image of the vehicle are recorded. The two wide-angle
images can be used as evidence that the vehicle was moving at
the time of recording. The zoom image gives a close up of the
number plate. The system records all relevant information associated
with the violation, including images, on removable hard disk
or optical disk facility. All data is protected against tampering
through use of encryption and data- integrity codes embedded
in the information. A built in flash module permits operation
at night. Violations are retrieved via central PC with a modem.
Operational parameters such as time into red may be locally
or remotely programmed into the unit.
