Roma Servizi per la Mobilità extended the adaptive traffic light management system with wireless sensors in the City of Rome. After the successful projects in via Nomentana, via Casilina and via Aldrovandi, Sky Light Sensors have been installed along the tramway route number 2 between Piazzale Flaminio and Piazza Mancini. The railway is mostly situated in a reserved lane but sometimes (as crossroads or turns) they merge with lanes dedicated to private transportation. The system monitors the tramway and also the surrounding streets with private vehicles. Take a look at the pictures.

Together with I-Tel S.r.l., Nabla Quadro is involved in a project of smart mobility and social inclusion in Cerignola (FG). Twenty-five parking sensors has been installed in the parking spaces reserved to disabled people. The sensors detect the occupation of single parking spaces and send data to the server. Parking data are associated to the identification of the entitled people who check in with a dedicated mobile app. In this way the system is able to detect illegal situations automatically and inform city traffic policemen.

Nabla Quadro started an R&D project to upgrade the Sky Light Sensor – Parking Version, which is based on optical and magnetic detection principle. The aim is to optimise this device to monitor aircraft parked at an airport stand, where aircrafts head towards after landing. The output is a brand-new product: Sky Light Aircraft System. Its main purpose is to solve the issue of knowing exactly when an aircraft occupies a stand, and also doing it in real time. In fact, airports don't have any certified system that is able to state the exact block-on and block-off times for airplanes in the remote stands. There are often inconsistencies between the communications made by airline pilots and ground handling operators. Sky Light Aircraft System is a wireless system to monitor individual stands, giving the exact block-on and block-off times. In this way, the airport is able to provide official and accurate data, avoiding misunderstandings between airlines and ground handling companies. The test site is inside the Milan Malpensa Airport, which is managed by SEA Aeroporti di Milano SpA. The installation involves 18 airport stands within the Terminal 2. The system will be monitored for 12 months, in order to evaluate the performance of the system in any meteorological condition and temperature.

Nabla Quadro and La Semaforica srl started a pilot experiment to evaluate an innovative wireless system for Translohr train detection approaching to crossroads. Translohr is a rubber-trained tramway system for urban applications. It sometimes has a dedicated street lane while other times can share its path with normal vehicles. The wireless detection system has been installed in Padua at the end of 2016

Trento City Council chose to install Sky Light Systems by Nabla Quadro. The sensors will detect whether a bay is vacant or not, as well as monitor traffic flows across the road network. The project started in April 2015. The installation has been rolled out and successfully completed at the end of July 2015. The project involves two different areas in the city of Trento. One system is aimed to count vehicles, while the other one is a complete instrument for counting, vehicle classification by length and parking bays monitoring. Check out the photos here.
