Livorno Smart City


For the public lighting system, the following technological alternatives were evaluated with an impact both from the point of view of energy efficiency and from the management point of view, in full compliance with the applicable regulations.

The advantages that can be obtained with LED technology combine both the positive aspects of a very low environmental impact, thanks to its energy efficiency and the absence of pollutants, and those of an excellent lighting and chromatic yield capable of improving comfort and road user safety. For these reasons, the design proposal provides for the replacement of all current lamps with the latest generation LED light sources. Currently, 16186 light sources are installed, consisting largely of lamps with SAP sources, an inefficient technology that has been largely superseded by new systems with higher efficiency.

The remaining road luminaires are however old and technologically obsolete, with low efficiency values, or with absent or inadequate optics, some without closing screen or with open, damaged, or degraded cup, insufficient degree of protection, inadequate from the point of view of energy saving.

To implement the modification of the light source, it is planned to act through the complete replacement of the existing luminaire and with the intervention of re-lamping LEDs, preserving the structure and the casing of the existing luminaire. Through the LED KITs it is possible to carry out a technological modernization and energy saving intervention of the existing artistic lanterns keeping the same fixture without replacing it in its entirety.

It was considered appropriate to replace all street-type luminaires with new latest generation “DigiStreet” – “Unistreet Performer” LED luminaires, and those for street furniture with Philips brand “ClassicStreet” or equivalent.

Safety in the various urban areas affected by the interventions and the continuity of the service will be guaranteed through the installation of a remote control and remote management system of the public lighting network.


    • remote on and off switching of the system
    • reduction of maintenance costs, through real-time reporting of any malfunctions
    • network monitoring to identify any anomalies
    • verification of consumption to always keep the actual energy savings obtained under control

    The electrical parameters will be monitored at the height of the ignition panel, where a local controller will be placed, capable of transmitting the data collected to the computer station, and remotely by emergency operators through mobile terminals. An Algorab remote control system for dynamic lighting will be used for the light flux adjustment system.

    The proposed system is called P5, a public lighting management platform that combines the advantages of a modern remote-control system for individual lighting points with the exceptional integration possibilities deriving from the use of communication technologies typical of WSN (Wireless Sensor Network).

    The Wireless Sensor Network (WSN) involves the use of electronic devices (sensors and actuators) that are able to work in a distributed way and share information through the same communication channel. The WSN provides for two needs: city sensing from the terminal nodes and a wireless network infrastructure to convey information.

    The Algorab P5 system fits into this context, which arises from the intuition of exploiting the light points as supports for the WSN network. The Algorab devices installed on the lighting bodies (P5) allow both to control the lighting according to local or remote logics, and to perform WSN router functions with the other control units.

    The radio communication between Algorab devices allows to create the WSN infrastructure that is used both for remote lighting control and for city sensing and smart city services.
