The contextAt present, the prevalent system to manage traffic light controlledcrossroads is represented by inductive loops.

The context

Some criticalities have emerged over the years:

Accuracy decreases when trafficincrease and in presence of vehiclesproceeding at low speed or stopping

Undercounting errors increase inpresence of poor pavementcondition

High failure rate due to torsion andtension caused by traffic flow andvariation in temperature

Installation and maintenance costs areremarkable due to the need toundertake roadworks

Sky Light Sensor technology

Wireless sensor for automatic detection of transit andparking of vehicles

Proprietary triple technologyItalian patent 0001379287

Sky Light Sensor is able to:

Supply real time traffic data

Detect parked vehicles

Interface with traffic light controllers

TRIPLE TECHNOLOGY

Magnetic

Optical

Infrared

TIME NEEDED

6 years of battery autonomy

5 mins to replace

15 mins to install

Sky Light Sensor technology

Patented optical technologyComparing the waveforms produced by the passage of a vehicle, it is observedthat the optical detection is more accurate with respect to the performance ofmagnetic sensors.

Magnetic sensor Optical sensor

• better performance in case of queues• vehicle classification by length is possible

Sky Light Intersection SystemSystem architecture

Sky Light Intersection SystemKey features

Precise control of traffic volumes

High performance also in case oftraffic congestions

The outer casing enable quickreplacement interventions in case offailure

Queue monitoring can be achieved byplacing wireless sensors at differentdistances from the crossroads
