Parkingstream is a startup focusing in the field of smart-cities/on-street smart parking. We use computer vision and Automatic Licence Plate Recognition techniques in order to help cities fully automate their on-street parking control and enforcement tasks and help them manage efficiently their parking resources. Parking enforcement today is mostly done by parking officers cruising the city, a rather expensive and inefficient process. At Parkingstream, by registering -at street level- the vehicles’ entrance and exit times, we can identify the parked vehicles and calculate their parking time. This info is correlated with the electronic payments data and in case of a mismatch an e-citation is issued. Like that Parkingstream can help cities eliminate their parking enforcement expenses and at the same time maximize their parking revenue.
