Deer danger on 195: sound signals to stop animals and visual signals for motorists
In the last year, a hundred accidents caused by sudden crossings: the Municipality of Pula relies on technologyPer restare aggiornato entra nel nostro canale Whatsapp
Technology to try to counteract deer crossing on the 195, the cause of numerous accidents, around a hundred in the last year alone in the Pula area.
The Municipality, together with Forestas and its veterinarian, Lucio Mandas, have decided to rely on a new dual system that allows, at the same time, motorists to be warned of the presence of animals on the roadway and the deer themselves to be dissuaded through the emission of sound signals that make the wildlife move away from the roadway. Sound signals that imitate the sounds of other predatory animals, which act as a deterrent to crossing, allowing to mitigate possible collisions between fauna and vehicles.
Several systems will be installed along the 195 starting this summer, in the areas where the most accidents have occurred in the past.
Description and operation
This is a system composed of a control unit and two self-powered solar panel road signs, to signal the presence of wild fauna to motorists by means of flashing or variable message panels. The system works through one or more infrared sensors that record the passage of animals and transmit the information via radio to an electronic control unit, which activates a signal.
A radar sensor registers whether the vehicle slows down to the desired speed. Otherwise, the system doubles the flashing of the optical signals to increase the driver's attention to be careful. The Doppler radar sensors have a detection range of 200 meters and are able to detect speeds between 0 and 299 km/h.
Councilor for Roads Stefano Deidda was keen to point out: «Thanks to discussions with the Region and in particular with the Department of the Environment, we have managed to obtain significant funding aimed at remedying a particularly serious problem that has been present for years, such as the presence of wild fauna near the Strada Statale 195, where several dozen road accidents occur every year. With the system we are about to implement, we expect to significantly reduce the problem».
