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
