Autostrade per l’Italia experiences a system on the Naples ring road that communicates directly with vehicles to optimize the flow of traffic. The goal: reduce queues and accidents through technology.
The experimentation of the “Dynamic Speed Limit” has started on the Naples ring road, the first service in Italy suggests to motorists the optimal speed in real time to avoid the formation of queues. The project, developed by Movyon (technological company of the Autorostrade group for Italy), represents a concrete first step towards the so -called Italian “Smart Roads”.
How the system works The mechanism is based on direct communication between infrastructure and vehicles through antennas distributed along the route and devices installed on board. The traffic control center collects data from sensors, portals and intelligent cameras, while a traffic model developed by the University of Naples Federico II processes information and calculates the optimal speed for each section.
During the tests, both common vehicles of the Fleet of the Naples ring road were used, enabled to receive the same information and make it available to the driver, and a self -driving car – a Maserati Grancabrio Folgore equipped with the robber -Driver system of the Polytechnic of Milan – capable of automatically adapting the speed to the indications received. The aim is to obtain the so -called effect “green wave” reducing expectations in traffic and increasing road safety.
In a few days of activity, the system collected and developed about 3.5 million daily transit data. The classified information includes class of the vehicle, direction and lane of driving, speed, length and headway (temporal distance between consecutive vehicles).
According to Movyon estimates, based on international studies, the adoption of the system could lead to a reduction in emissions and travel times from 5 to 15% and a decrease in accidents from 10 to 30%.
The pilot project and the next steps. The first test phase took place on a stretch of 3 km from Vomero to Fuorigrotta. By the end of 2025, the goal is to extend the system to the entire ring road of Naples, equipping the entire path with antennas and sensors. Neapolitan experimentation is part of the largest highways for Italy strategy for the development of advanced technological solutions, confirming the group as the first Italian dealer to have authorized the circulation of autonomous driving vehicles on its open traffic network.
