Another possible functionality of
the LPR system is real-time hotlist matching. Collaborating with law enforcement agencies, cities can obtain lists of vehicles of interest (also known as hotlists), such as wanted felons, amber alerts and stolen vehicles. These lists can then be loaded into
the sweepers’ LPR systems so that every license plate captured is verified against these lists as a background process. In the event of a positive match, an alarm would silently be sent in real-time to a back-office system operator, or even directly to the respon- sible law enforcement agency.
Taking a look ahead Moving forward, cities may be
faced with challenges when rolling out LPR technology. On the legislative front, changes may be required to issue tickets by mail, rather than serving themon-site. There also may be some questions
on the validity of the images as evi- dence of the violation, but LPRsystems have proven they can overcome these obstacles with their imaging quality, the precision of their geo-localization data, and the relia- bility of their chain of custody.
Cities also may face pressure on
public privacy issues. However, LPR systems focus mainly on the vehicle and the license plate, and not on vehicle occupants. Furthermore, all non-cita- tion data can be immediately discarded, excluding the “Big Brother” effect. Overall, license plate recognition
technology has proven itself to be an efficient productivity tool and is worth a look for any city with street-sweeping operations. LPR technology will reduce costs
associated with additional patrol staff needed to enforce the sweeper routes and will allow parking officers to focus on higher priority enforcement tasks. It may also dramatically increase
the number of violations detected and enforced, providing a very fast return on investment. But at the end of the day, LPRtech-
nology brings something even more important to the table: empowering cities to be greener by keeping their streets clean and clear of pollutants.
