Autostrade Tech has developed the technology that makes it possible to collect tolls through a device called Telepass®. Telepass is a "semi-passive" transponder: it has an independent power supply but only transmits when interrogated by the reader. Telepass allows dynamic toll collection using microwave DSRC (Dedicated Short Range Communication) technology at a frequency of 5.8 GHz for communication between devices in vehicles and the infrastructure of the lane.
The automatic toll collection system with Telepass is applied on motorways with open and closed toll systems. Each Telepass gate, whether entering or exiting, has equipment that automatically manages transits, maintains the dialogue with the on-board terminal and the connection with the information systems to charge for the transit according to the logical steps illustrated in the following image.
Microwave DSRC technology using a frequency of 5.8 GHz is particularly suited to toll collection since it allows to create highly robust systems, in terms of:
In addition, the lane software:
For this reason:
There are currently more than 8 million Telepass devices on the Italian motorway network.
