L’autoroute révélateur des territoires et support de mobilités nouvelles.

Seeing the highway differently

Considering a highway built in the 1960s today means reinvesting to update a Greater Paris network designed 40 years ago, a phase of prosperity when new highways and new towns sprawled relentlessly, along with the famous RER system (rapid transit train between Paris and its suburbs).

 

Over time, Highway A4 has become a complex territorial object, a structuring network supporting local and metropolitan mobility. In any event, it is a functional and very standardized object serving a single-occupancy vehicle traffic. This use of space is no longer a sealed fate. Improving Highway A4, from the mobility point of view, amounts to broaden the range of services and give them the right of way over the question of infrastructures.Where highway trivializes landscape, our project offers a highway that reveals it. It stages a succession of dense urban and natural landscapes and dramatizes the perception of each of them.

 

The  extent of this project, its multidisciplinary nature and its cooperation system make it as completely unique as absolutely crucial for the Greater Paris metropolis. We’re at a place and time where highways can become managed spaces able to serve public transit. 

 

The study suggests to make Highway A4 a prototype for the transformation of the Paris region highways, following principles which proved feasible:

- creation of a real metropolitan public space,functional as much for the environment as for the local residents.

- reclaiming the motorway junctions to pool and enhance ongoing urban projects. The highway can support the economic development for the territories of Eastern Paris.

- an optimized distribution of the highway space : creation of a carpool and public-transit lane.

- a dynamic distribution of the highway capacity following traffic-flow peaks.

- an traffic pedagogy addressing all highway users.
