APRR-AREA

 

This is a first in France. In September 2020, AREA, a subsidiary of APRR, opened an 8 km lane reserved for carpooling on the A48 motorway, at the entrance to Grenoble (Isère). This section is particularly busy during rush hour. This commissioning was made possible by the law of orientation of mobilities of December 2019, which makes it possible to reserve dedicated axes on motorways for carpooling, and not only for buses and taxis. In concrete terms, in the event of a slowdown, the left-hand lane (in the Lyon-Grenoble direction) is reserved for vehicles with at least two people on board, and for very low emission vehicles, as well as for taxis. A dynamic signage system informs drivers that the left lane is in "reserved mode" by displaying a white diamond on a black background on illuminated signs (an experimental sign compared to the Highway Code).


The aim is to fight against "auto-solicitation" and thus reduce emissions of greenhouse gases and atmospheric pollutants. This is an important issue, given that Grenoble is the fourth most congested city in France, according to the Traffic Index ranking drawn up in January 2020 by the GPS manufacturer TomTom. Before September 2020, AREA found that only 17% of travellers had at least two people in their car. Nationally, it is estimated that 70% of home-to-work journeys are made in individual cars.

Recently renamed the M6/M7 after its management was transferred to the Lyon metropolitan authority (Rhône), the section to the north and south of the Fourvière tunnel has also been converted to carpooling. Since the end of November, a lane on each side has been reserved for vehicles carrying more than one passenger. Eiffage Energie Systèmes set up the necessary system in a consortium with Pryntec.

Our consortium with Pryntec won the entire contract," explains Serge Balmonet, Director of Transport and Mobility Development for Centre-Est at Eiffage Energie Systèmes. It includes the supply, installation, connection and qualification of the control system equipment, as well as the various sensors and variable message signs informing users. "

In concrete terms, these lanes are effective on the M6, to the north, between the La Garde interchange (Dardilly, exit 33) and the Valvert interchange (Tassin-la-Demi-Lune, exit 36) and on the M7, to the south, between the Pierre Bénite interchange and the Confluence interchange. These lanes are reserved for vehicles carrying at least two people, Crit'Air 0 vehicles, taxis and future express buses on the Pierre-Bénite/Confluence section.

These two projects demonstrate that this solution is adaptable both on motorways and in dense urban areas.

In terms of sustainable development, the challenge is major: to succeed in reducing auto-solicitation and the number of short and medium distance trips. In a methodological guide on the development of regular short- and medium-distance carpooling, Ademe notes that "local mobility, which corresponds to all journeys of less than 80 kilometres, represents 60% of total mobility in terms of distance and 98% in terms of volume. Of these trips of less than 80 km, 84% are made by private car, 7% by urban public transport and 4% by train.

Ademe adds that "it is for work, home-work and home-study trips that the vehicle occupancy rate is by far the lowest (1.08 on average for home-work trips, including family accompaniment) and the only one that does not increase with distance", whereas for all other reasons, the occupancy rate increases with distance, especially beyond 20 kilometres. Implementing infrastructures to encourage carpooling is one of the recommended responses "for use by local authorities and employers alike" - bearing in mind that out of 27.4 million people in employment, 20.6 million of whom have a permanent job, 14.9 million, or 72.2%, use their car to go to work (although they do not use their vehicle every day).

Sustainable Development

    APRR and Eiffage Énergie Systèmes are committed to sustainable mobility in order to contribute to the energy transition and fight against climate change.

    Carpooling lanes, by encouraging the sharing of vehicles, reduce noise and pollution, thus promoting well-being among city dwellers as well as for users of motorway networks.

    In general, carpooling contributes to reducing the number of vehicles on French roads while there are 250 km of traffic jams every day on average in the large cities of France .

    The carpooling lane on the A48 reduces autolism (being alone in your vehicle), and, with it, the impact of traffic on the environment, as well as congestion phenomena and also allows limit the costs of mobility. Before September 2020, AREA found that only 17% of travelers were at least two in their car. By making the journey time of carpoolers more reliable, the reserved lane is a lever to encourage the practice of carpooling.

Testimony / Feedback

    APRR-AREA, Eiffage Énergie Systèmes and Pryntec are experimenting with carpooling . For the reserved lane to meet the fluidity objectives, it is essential to check that the vehicles present on this lane are indeed authorized to circulate there.

    Concretely, the innovative Pryntec solution installed on the central reservation makes it possible, thanks to software equipped with artificial intelligence combined with cameras and sensors, to analyze the occupancy rate of vehicles, both at the front at the rear - regardless of their speed, the occupants' position in the passenger compartment, the weather or light conditions.

    This new generation of sensors is based on technology known as “deep learning” or self-learning, which enriches the performance of the system as it is used.


    Since December 21, 2020, to promote the practice of carpooling, the Métropole de Lyon has opened reserved lanes on the M6 and M7 axes between Dardilly / Limonest and Pierre-Bénite . Between Dardilly / Limonest and Pierre-Bénite, there is no longer a motorway but two urban boulevards: M6 and M7.

    Why carpool lanes?

    • to reduce the number of cars in circulation,
    • lower air pollution,
    • and reduce noise around these roads
