The stakes of the Grand Paris Express project

BRION Marc & SCHWAB Oscar

Le Grand Paris is an ambitious project that aims to redefine the Paris region by creating a more competitive, sustainable and attractive metropolis.

The project was born out of a desire to unite Paris and its suburbs into a single urban body, in order to solve the problems of fragmentation and territorial inequality that have plagued the region for decades.

The Grand Paris project involves the development of a high-performance public transport network with the creation of the Grand Paris Express, a new automated metro line connecting the various centers of activity and life of the metropolis.

The aim is to increase the economic attractiveness of the region by encouraging the establishment of enterprises and research and innovation centres.

Furthermore, the Paris Metropolitan Area aims to improve the quality of life of local residents by strengthening the presence of nature in the city and promoting cultural and social exchanges between the different regions of the metropolis.


The network in Ile-de-France

Curent transport network

The Ile-de-France transport network is one of the densest and busiest in the world, with over 12 million passengers per day.

However, they are often criticized for being unreliable and uncomfortable, especially during rush hours.

Subway and RER lines are often crowded, making travel stressful for passengers. In addition, the bus network is often overloaded, and trams are still few in number and mainly operate on the outskirts of the region.

In light of these challenges, the Grand Paris project aims to modernize and expand the region's public transport network in order to offer travelers a more comfortable and reliable travel experience.

The Grand Paris Project

Lines of the Grand Paris Project

The Grand Paris project is underway and progressing steadily. Construction of the Grand Paris Express, a network of automatic metro lines designed to link the metropolis's various centers of activity and life, is well underway. To date, two lines are already in service (15 Sud and 14), and work is continuing on the other lines due to come into service between 2024 and 2030. Other projects to modernize and extend the public transport network are also underway, including the extension of certain metro and tramway lines, as well as improvements to existing stations. Although the project is encountering delays and difficulties, it should eventually lead to a significant improvement in the quality and fluidity of travel in the Paris region.

An example of the advantage offered by the Grand Paris Express

Comparison of path with and without GPE

In this example: Reuil - Suresnes - Mont Valérien to Arcueil - Cachan. The journey would take 16 minutes and 15 seconds with Metro 15 and therefore the Grand Paris Express, compared with 1 hour 5 minutes and 35 seconds with the usual route. The Grand Paris project should offer many advantages for people coming from the outskirts of Paris compared with the current transport network. First and foremost, the Grand Paris Express will provide better service to outlying areas, connecting the suburbs to each other and reducing journey times to the metropolis' hubs of activity and life. In addition, the construction of new automatic metro lines should improve the fluidity and regularity of journeys, reducing waiting times and delays. Last but not least, the project should help to relieve congestion on existing public transport systems, by offering travel alternatives to passengers in the region's most densely populated and congested areas. In short, the Greater Paris project should enable people living on the outskirts of Paris to benefit from a more efficient, comfortable and faster transport network for getting around the metropolis.

The Grand Paris and the 2024 Olympic Games

Comparison of the stations of the Grand Paris located at less than 800 meters of the Olympic Games structures and the others.

Stations of the GPE and Olympic Games facilities

Even if the future stations of the Grand Paris system are not specifically located near the sports facilities of the 2024 Olympic Games, they will nonetheless play a key role in smoothing traffic flow and facilitating travel for athletes and visitors in Paris's outer ring. By connecting the cities and towns of the Paris region via modern, high-speed public transport lines, these new stations will facilitate access to sports facilities located on the city's outskirts. Travellers will be able to avoid traffic jams and delays by taking the metro, streetcar or train lines linking the various urban areas. The new Grand Paris stations can also contribute to the economic development of the districts they serve, by stimulating job creation in the tourism, hotel and restaurant sectors. Even if the stations are not located close to the 2024 Olympic sports facilities, the future stations of Greater Paris will play a key role in the success of the event by facilitating travel for participants and visitors, while improving urban mobility in Paris' outer ring.

Comparison between current station services and future Grand Paris stations at 800m of Olympic Games sports complex

The Grand Paris stations will play a crucial role in the success of the 2024 Olympics, bringing spectators closer to the Olympic venues and facilitating their access to the various competitions. The new metro, tramway and commuter train lines will serve the various Olympic venues and make it easier for spectators to travel between different urban areas. If the Grand Paris stations are too far from the Olympic venues, spectators will be able to use existing public transport lines to get to the various competitions. The existing stations, as well as the new Grand Paris stations, will also help to relieve congestion on the roads, thereby enhancing the spectator experience and reducing the environmental impact of the event. The Grand Paris stations will be key to ensuring the success of the 2024 Olympic Games by bringing spectators closer to the Olympic venues and facilitating their access to the various competitions while improving urban mobility in the Paris region.

Impacts of delays on GPE sites on the 2024 Olympic Games

The arrival of the Olympic Games in Paris in 2024 is a real source of economic and cultural development for many areas on the outskirts of Paris. The main driving force behind this development is the installation of the various GPE lines. The completion date was scheduled for the opening of the Olympic Games. In fact, the management of the 2024 Olympic Games had placed numerous sports venues and centers in the vicinity of the planned future stations. However, several GPE infrastructures are behind schedule and will not be delivered in time for the 2024 Olympic Games.

As a result of these delays, the Olympic management has decided to relocate a number of sports centers, including the volleyball and shooting complexes, the handisport centers and the aquatic center from St Denis to Nanterre. Beyond the undeniable budgetary impact on the organization of the Olympic Games, there are other major repercussions. The economic repercussions are clear. In fact, some areas will not have the expected influx of visitors, inevitably impacting the sales of local businesses and lessors. Many real estate markets that were created to meet the future housing needs of Olympic visitors are beginning to feel the pinch. As a result, the growth of many of the more precarious areas will not reach the expected development forecasts.

As a result, fans, athletes and visitors will have easier and faster access to sports facilities in the Paris region. The introduction of these new public transport stations can also contribute to the economic development of the surrounding districts, attracting more tourists and stimulating job creation in the hotel, restaurant and retail sectors. Locating public transit stations close to sports facilities is a key factor in encouraging the practice of sports and facilitating access to culture and leisure for all.


Conclusion

The existing and future public transport stations under the Grand Paris project play an important role in urban mobility in the Paris region.

The new Grand Paris station will help ease road traffic and bring spectators closer to the various Olympic venues, while placing the station closer to sporting venues. These facilities will facilitate access to infrastructure and facilitate the smooth movement of athletes and visitors.

The development of an efficient and accessible public transport network is a major challenge for the city of Paris and the Ile-de-France region, which faces increasing mobility challenges.

The Grand Paris project and investments in transportation infrastructure represent an ambitious response to these challenges, improving the quality of life for residents, promoting economic development in the districts they serve, and increasing the number of visitors. This increases the attractiveness of the region to investors and investors.
