Our system consists of a speed enforcement network of up to 1000 Average Speed Cameras and an Evidence Retrieval and Control Unit (Instation).
Using Automatic Number Plate Recognition (ANPR) technology, our average speed cameras are able to ‘read’ the number plate of every vehicle which passes its field of view and creates a time, date and location file for that vehicle.
Should a vehicle reach the next camera too quickly, the enforcement server will highlight a violation has occurred. These violations can then be exported
The Vehicle Registration Number (VRN) for each passing vehicle is read, accurately time-stamped and added to an encrypted batch of VRN’s stored on the camera. Every batch of 30 VRN’s is sent via a GPRS or ADSL connection to the PIPS Evidence Retrieval and Control Unit (ERCU) ‘Instation’ enforcement server. The ERCU has been configured with the distance between each camera and the speed threshold. When
a vehicle passes an exit camera the ERCU works out the speed of the vehicle using the elapsed time between the links and the distance.
The ERCU pulls the images from each camera for violations only and combines them into an encrypted Violation Record, which is written to CD. The free-space on the CD can be constantly monitored using the ERCU and an email can be sent when it is 90% full. The CD can then be retrieved for review in the Offence Viewing & Decision System (OVDS) with selected violations being exported to a ticketing back office.
Within the PIPS Average Speed Camera System, air-gap isolation provides absolute evidential integrity. All of the data is stored on Write Once Read Many (WORM) CD-R’s and can be inspected if queried. The data is also encrypted on the media Session Manager and may be held securely, if required.
The PIPS Evidence Retrieval and Control Unit (ERCU) is loaded with information on road topology; cameras, sites links, o sets and the desired speed threshold.
It receives time stamped VRN’s from the cameras and detects any violators. The ERCU is able to request and receive the images and assembles an encrypted violation record to CD.
Safer than traditional spot speed systems.
Traditional spot speed enforcement has often been accused of causing accidents, not preventing them. Safety campaigners from all over the world claim that spot speed cameras cause heavy breaking and sudden acceleration, leading to accidents and serious injuries.
The PIPS Average Speed Camera System eliminates the hazards caused by spot speed cameras, while still maintaining traffic flow. Through correct signage, drivers know that they are approaching an average speed enforcement zone and they are able to adjust their speed accordingly and safely.
The PIPS system monitors the speed on an entire road network, not just at one location. By monitoring a whole section of a road network the system also removes the chance that drivers will learn where speed cameras are located and only drive within the legal speed limit when they are passing the speed camera. Traditional speed cameras are only able to enforce the speed on a very short distance of road whereas the PIPS Average Speed Camera System can enforce the whole road or even village, town or city. In addition, spot speed cameras have historically been accused of costing tax payers large amounts of cash to maintain.
Our average speed cameras are fully integrated and require minimal maintenance.
Safer for communities.
The entrances to schools are one of the most important areas for controlling speed because of the high number of vulnerable pedestrians.
Young children may not fully understand the dangers of the road and slowing tra c to the legal speed limit means that lives can be saved.
We have designed our system to be enforceable over just 100 metres with speed limits as low as 20mph, ideal for deployment at school and college entrances.
With over 10,000 ANPR cameras installed across the UK, our team of highly experienced service engineers will ensure that the system is correctly setup and calibrated. Once the system is in place, you can be con dent that it will continue to perform, providing extremely accurate read rates. Indeed, our cameras have been independently tested to ensure that they continue to perform in a variety of operating environments. PIPS average speed cameras use our own Optical Character Recognition (OCR) engine, which is widely recognised as the most advanced in the industry.
Helps ease traffic flow and minimise congestion.
Average speed enforcement is an e ective tool for reducing journey times by limiting the disruption to tra c ow that spot speed, tra c lights or speed bumps can cause. The implementation of average speed solutions has shown that travel times actually decrease through the enforcement zone due to more disciplined tra c ows. The side-e ect of steady tra c ow is that it will help reduce the amount of fuel burned and as such, decrease particulate matter and noise pollution.
Easy to install.
PIPS Average Speed Cameras can be mounted on a range of existing street furniture including street lights, bridges and motorway gantries and are capable of taking their power from a street light or other existing power source. They have also been approved for mounting on passive safety poles so there is no need
to install a crash barrier, keeping installation costs to a minimum.
The cameras are able to operate using wireless (GPRS or 3G) communications so all of the required electronics for the camera contained inside a single unit. With a possible installation height of up to 7.25m from the centre of the lane of traffic, this vastly reduces the chance of any vandalism to the system.
The PIPS Average Speed Camera System always favours the driver (and helps limit legal challenges) by minimising the speed reported.
The system will enforce on the minimum possible distance and always favour the driver irrespective of when the plate is read.
The minimum distance is the latest possible leave point at the entrance site to the earliest possible arrival point at the exit site.
The distance travelled within the eld of view of the camera is ignored.
The PIPS Average Speed Camera System enforces the distance between X’ and Y’ (Green), instead of the distance between X and Y (Red) which has actually been travelled:
With over 20,000 cameras deployed around the globe, PIPS is a worldwide leader in Automatic Number Plate Recognition (ANPR) technology, designing, manufacturing and supporting our complete line of ANPR products and services.
At the heart of the PIPS Average Speed Camera System is the PIPS Optical Character Recognition (OCR) engine that has been internally developed and maintained over a number of years, and is widely recognized as the most accurate in the industry.
PIPS OCR engines are very tolerant of skewed and off-axis number plate reads, plate sizes, syntax rules, and designs. Our system exceeds the standards set out by the Association of Chief Police Officers (ACPO) for ANPR technology and is Home Office Type Approved (HOTA), so you can be con dent in the PIPS Average Speed Camera System as a robust, cost-effective solution for average speed enforcement.
