ANPR – Number Plate Recognition Technology
July 16, 2008
Recent advances in Automatic Number Plate Recognition (ANPR) technologies have lead to a greater acceptance of the technology by car-park operators. The new digital ANPR technologies present greater read rates than traditional CCTV/PC based technologies and offer far greater flexibility in deployment and customization than previously available.
By attaching a unique signature to every vehicle entering and exiting a car park the potential of a car-park management system is greatly enhanced. The signature widely used by vehicle identification technologies is usually the registration number displayed on the front and rear of the vehicle. To robustly read this plate in all weather conditions, day and night and to increase the ability of a system to read dirty plates, Alpha Vision Design has developed a stand alone digital ANPR station that can extract the registration number and automatically present the number for processing.
The applications of ANPR technologies can be used for tolling, police enforcement, journey time analysis, average speed violation and access control. Within the car parking domain, most car park operators use ANPR technology as a medium to locate lost vehicles, to calculate occupancy times and to dramatically decrease the revenue loss associated with ticket fraud.
ANPR is also finding favour within non-supervised car parks as a means to control access via a white list. This white list contains a list of vehicles with known access rights. Suitable for hotel, apartment and company car parks, this negates the use of disposable paper tickets and wireless FOBs. Companies with large fleets are introducing ANPR as a cost effective method of tracking their vehicles throughout their depots. Large supermarkets and chains are also beginning to utilize the information obtained from their car-parks as a way of highlighting demographic patterns with a view to maximizing profits.
For any traffic management system to be a success, the read rate must exceed 99%. Traditionally most operators shied away from ANPR when they discovered that their true read rates were rarely above 60%. In real world applications, this was the limit, not due to poor software but the result of using conventional CCTV systems to obtain the images. CCTV technology is 50 years old and does not lend itself well to computer recognition systems.
The common processing core for CCTV based ANPR systems is a PC. CCTV/PC based systems are not robust and are unacceptably high maintenance. To counter this, Alpha Vision Design has developed a self-contained ANPR system designed specifically for the car parking industry. This system includes an integrated illuminator, high resolution digital camera, digital analyser and on-board relays, all contained in one standard security housing. Only mounting and a power cable is required – an industry first!
A high resolution camera obtains images that are over sixteen times larger in area size than CCTV images. Combined with a wider field of view, now only one camera is required to capture both the registration plate and an overview of the vehicle, and vehicle placement within a lane is no longer an issue which leads to greater capture rates.
The camera /computer unit can in real time adjust the exposure, gain, and the integrated on-board IR lighting to maximise the contrast and readability of the registration plate, including dirty plates, variations in plate reflectivity, strong headlamps and adverse weather conditions. This cannot be done with CCTV/PC based ANPR systems.
The setup is easy and is only required once per site, with no re-configuration necessary even after a power outage as the system will reboot automatically. On a typical 800 bay car-park, the system can also store up to five years of data, capturing and time stamping an image of every vehicle entering and exiting the facility. The system is true Plug & Play and can directly control a parking barrier via its on-board database and integrated relays. For configuration, simply use any standard web browser to manage the ANPR station – no third party software is required to manage the entire ANPR network.
Our standard systems are shipped in three versions. We have an ANPR station designed for operating at a 10 meter and 25 meter range, and a system for high speed traffic applications. All systems are pre configured and only mounting is required. The ANPR stations can act stand alone or integrate with an existing parking entry ticket/gate system. For remote applications, the ANPR station can also be configured to run over GPRS, TCP/IP and WIFI Networks.

London’s priciest car park ‘charges £43 for six hours’
July 16, 2008
Parking in the capital’s most expensive car park will set you back £43 for a six-hour stay, a London newspaper said Monday.
The multi-storey car park on Pavilion Road in Knightsbridge has been named London’s costliest by the Evening Standard. Located walking distance from luxury department store Harrods, the NCP-run facility charges drivers £7.20 an hour.
The paper said the highest hourly rate could be found at the NCP in Berners Street, Bloomsbury, which charges £8 per hour but a mere £33 for six hours.
The survey found that people driving into the capital for a day of shopping are better off parking at the Masterpark on Oxford Street where charges are £5 an hour or £24.50 for six hours.
AA president Edmund King told the Evening Standard the charges were “mind-boggling”, adding that they keep many shoppers out of central London.
Bargain hunters unwilling to walk, cycle or take the Tube or bus, should head for the City of London area car parks, the paper said, with parking at Spitalfields and Smithfield Market a steal at £2 an hour.

Japanese Parking Lots Accept Contactless Payment
July 12, 2008
Japanese parking lot operators are beginning to accept contactless payments as card issuers continue to try to make inroads in Japan’s cash-based consumer economy. More and more pay-by-hour lots are accepting payment via contactless cards or mobile phones equipped with contactless chips, according to the Nikkei news service. Nippon Parking Development Co., which runs about 100 lots in Tokyo and elsewhere in Japan, will accept iD, the contactless credit brand launched by mobile network operator NTT DoCoMo and credit card company Sumitomo Mitsui, the Nikkei report says. Another parking-lot operator, Park 24 Co., accepts three contactless electronic purses: Edy, Suica e-money and PiTaPa. The latter two e-purses are mainly used to cover transit fares in and around Tokyo and Osaka, respectively. Overall, Japanese consumers make more than 90% of their purchases in cash, according to DoCoMo estimates. To capture a piece of this market, card issuers are supporting a total of five major brands of contactless credit and electronic-cash programs, with more on the way. Consumers can make contactless payments at thousands of convenience stores and other merchant locations, but few of the card-reading terminals are interoperable, which threatens to confuse consumers. Masao Nakamura, president of DoCoMo, told the Nikkei Marketing Journal this week that his company is now working on a contactless point-of-sale terminal that can accept all three brands of contactless credit in Japan.

Networked Parking System Alerts Drivers to Free Spots
July 12, 2008
New technologies promise to revolutionize the hunt for a parking spot in big cities like San Francisco. Donald Shoup is along for the ride.
“This fall, San Francisco will test 6,000 of its 24,000 metered parking spaces in the nation’s most ambitious trial of a wireless sensor network that will announce which of the spaces are free at any moment.
Drivers will be alerted to empty parking places either by displays on street signs, or by looking at maps on screens of their smartphones. They may even be able to pay for parking by cellphone, and add to the parking meter from their phones without returning to the car.
Solving the parking mess takes on special significance in San Francisco because two years ago a 19-year-old, Boris Albinder, was stabbed to death during a fight over a parking space.
“If the San Francisco experiment works, no one will have to murder anyone over a parking space,” said Donald Shoup, a professor of urban planning at the University of California, Los Angeles, whose work on the pricing of parking spaces and whether more spaces are good for cities has led to a revolution in ideas about relieving congestion.”
