The Government provides roadside parking spaces to meet the short-term parking needs of motorists. In order to provide real-time information to facilitate motorists for finding vacant parking spaces, the Transport Department is planning to install sensors at about 250 non-metered on-street parking spaces to detect whether the parking spaces are occupied or not, so as to reduce the time for vehicles circulating on the roads for finding vacant parking spaces.

The non-metered on-street parking spaces for the trials of installing sensors are mainly located at the parking spaces for private cars, the disabled and coaches near some outing sites in the New Territories as well as the parking spaces for the disabled in other areas, so as to evaluate the effectiveness of the detection technologies to be applied at different locations. Please refer to the following link for the location and number of the concerned non-metered on-street parking spaces. The Transport Department will review the effectiveness of the trial scheme after its completion, and then consider installing sensors in other suitable on-street parking spaces.

Implementation Arrangement

The installation of sensors is planned to commence in phases from the second quarter of 2021 for target completion by 2022. Upon completion of the system testing, the relevant real-time information will be disseminated to motorists through the mobile / web version of “HKeMobility” and the website of “DATA.GOV.HK”, to assist motorists in finding vacant non-metered parking spaces.

The sensors will be installed in suitable position in the parking spaces. Please refer to the figure below for details. The sensors will employ radar and geomagnetic induction to detect whether the parking spaces are occupied. For the purpose of protection of privacy, the sensors will not collect any personal information, vehicle model or vehicle registration number, and will not have photographic or recording functions. The installation works will mainly involve excavation as well as installation and testing of the sensors within the non-metered on-street parking spaces. Temporary traffic arrangement will be implemented during the works period. It is expected that impact to the public is minimal.

During the installation period, the contractor engaged by the Transport Department will launch a 24-hour customer service hotline (tel. no.: 6509 0375) for handling enquiries in relation to the trial scheme.
