City Parking Guide is an ITS application developed by a R&D consortium of Greek academia, industry and public authorities. It uses wireless sensor networks and web technology in order to monitor, control and manage roadside parking in large cities.
The system uses the capabilities offered by distributed collaborative wireless sensor nodes for detecting free parking spaces along road axes and monitoring their use in frame of a payable or not parking service. Thus the parking administrator can be aware in real time regarding the availability or not of parking spaces in the controlled area and pass this information to drivers looking to park their car. The information can be sent to road screens or it can be accessed through a proper mobile application. The system can guide the driver to a free place, monitor the time that the place is used (paid or managed otherwise) and inform the manager or the driver for time limit violations. The system combines information from wired sensor networks (traffic cameras) correlating the traffic in adjacent roads with the parking demand. System data can substantiate decisions and support the re-engineering of the management of parking spaces in a rational and safe manner locally.
