Parking Angel

Parking Angel is a patented system by Nabla Quadro for automatic management of parking bays reserved for specific users or vehicles. For example, it is useful to manage parking bays for people with disabilities, loading zones, electric vehicle charging stations or emergency vehicles.

Each parking bay is monitored by a wireless Sky Light Parking Sensor, which is installed in the ground. Data are sent to the server using LoRaWANor NB-IoT technology.

When a vehicle occupies a parking bay, the system can identify whether the driver has a permit to park in the controlled bay or not, thanks to the Bluetooth connection (BLE Beacon) and the Parking Angel app installed on the smartphones of the users.

Nabla Quadro also developed a hardware token to replace the authorization function of the smartphone. Drivers can leave the device inside the vehicle and be automatically enabled when they park in a bay reserved to them.

Permission is managed through automatic passwords generated by the application. The system can’t identify or communicate to Nabla Quadro any personal details such as the name of the driver who is parking in a specific bay, or his phone number, or the MAC address of the device. This is a specific choice of the company to protect the users’ privacy.

Local signals as LEDs or buzzers may be added to attract attention to the infringements, especially in those projects aimed at raising awareness towards the rights of a particular group of users, like accessible parking. At the same time, police authority receives a communication remotely.
