The new dynamic lanes on the highway that are increasing in number, and how to use them and exploit the important advantages


there Dynamic fourth lane It was implemented as a response to deal with traffic congestion at busy times by relying on road signs. This innovative solution is adopted to increase the capacity of an important arterial road, which records a large volume of daily traffic, with a peak of up to 200,000 vehicles per day, with a special effect of heavy vehicles.

Due to the presence of residential and industrial settlements that prevent vehicular widening, the dynamic fourth lane represents an effective congestion management solution without the need for permanent structural modifications. Let’s dive into it all:

  • What is a dynamic lane on a highway?
  • New examples of dynamic lane on the highway

What is a dynamic lane on a highway?

there Dynamic fourth laneIt is defined as an emergency lane that can be used by cars and heavy vehicles, and is opened or closed based on traffic conditions detected along the arterial route. The remote sensing and analysis system installed along the road uses sensors, radars, scanners and cameras to constantly monitor traffic flow.

By modeling and Use of artificial intelligencethe conditions under which the fourth lane can be opened, thus facilitating the flow of traffic, are determined, in particular on the sections leading to the interconnection with the A8 and A4 motorways towards Turin.

there technology platform Developed and managed by Movyon, a division of Autostrade in l’Italia that specializes in developing new mobility technologies, it plays a key role in this process. The conditions under which the fourth lane can be used are determined by vehicle flow analysis and prediction algorithms based on data collected by the detection sensors.

The signaling system communicates in real time with users while they are crossing the range Changes in lane use and applicable speed limits. Another device, known as Automatic Crash Detection, detects events occurring on the road and can affect fourth lane use. This monitoring is done through the use of AI-powered radars, laser scanners and cameras that constantly analyze the condition of lanes and traffic.

According to Autostrade per l’Italia, the implementation of this new system is not only Improving travel conditions for users in critical traffic situations, but it also generates environmental benefits. It is estimated that about 1.5 tons of carbon dioxide will be saved per hour from the activation of the dynamic fourth lane in the planned 10 kilometer stretch.

New examples of dynamic lane on the highway

The urban section of the A4 motorway, between Viale Certosa and Sesto San Giovanni, represents one of the busiest sections in Italy. Every day, about 200,000 vehicles pass through this section, ie Three times more congestion than the Autostrade average for all of l’Italia’s network. Motorists often find themselves stuck in a heavy traffic area, with long waiting times to get to the exits.

To resolve the vehicle discomfort, Autostrade per l’Italia introduced a dynamic fourth lane between the Cormano and Viale Certosa exits in both directions. This project spans a Total stretch of 9.3 kmwhich extends from the Certosa exit to the Cinallo Balsamo antiphonic gallery.

The intervention was conducted in collaboration with Movyon, an ASPI Group company specializing in technological innovation. Movyon has developed a control system to manage the transition from a three-lane plus emergency lane to a four-lane configuration.
