ANPR

What is ANPR?

ANPR or Automatic Number Plate Recognition is a technology that scans vehicle number plates to create data regarding that vehicle’s location. This data is captured through scanners or cameras, which is then cross-referenced for the purposes of traffic, law enforcement or, indeed, car park management.

What information does ANPR access?

As well as determining your location and vehicle speed, ANPR has access to information that relates directly to that of your number plate or registration number. This means it can determine your vehicle’s make, model and colour (much like when using GOV.UK’s vehicle enquiry service).

In terms of car park management, this means ANPR gates can recognise when your car is entering and exiting the car park.

Where is ANPR used?

ANPR technology is typically used:

  • On motorways for law enforcement and traffic monitoring
  • In car parks for management and security purposes

How does ANPR work on motorways and roads?

The following outlines how ANPR works on motorways and roads.

Law enforcement

ANPR is used in cameras on roads to monitor and determine vehicle speed. This is achieved by taking timed images between two very close locations. This then allows fines to be issued for any illegal speeding.

What’s more, the police also use ANPR technology to detect uninsured, untaxed and stolen vehicles as well as assisting in solving major and unorganised crime cases.

Traffic monitoring

Highways England uses ANPR cameras on smart motorways to control traffic flow by setting variable limits.

Additionally, these cameras can also be used to help calculate journey times; when a vehicle passes a camera, its number plate is read and converted into a non-unique reference number or tag. The vehicle and its number plate will then generate the same tag each time it passes a Highways ANPR camera. Journey times can then be calculated when analysing the time taken between passing a camera.

How does ANPR work in car parks?

Car park management

By using ANPR, our clients benefit from easier payment processes, clearer visibility of car park spaces as well as ticketless systems (e.g. paying through a mobile app) if desired.

We have installed ANPR systems for a number of car parks in the country, including near Bolton, Sheffield, Weymouth and Southampton.

Security

ANPR also works to enhance levels of security as the technology allows the ability to deny or grant vehicles access to a car park or facility.
