Cities are now in a pivotal period that requires us to rethink all established urban systems. The New York Whydrive project, completed with the Metropolitan Collective, proposes to develop a network of autonomous, shared electric vehicles that respond within a limited area to the demand for journeys, that, to-day, are motorised. Optimised occupation of vehicles, regulation of their speed and the frequency of their journeys will give them a smaller spatial and temporal footprint. By simulating this new distribution of users’ movements, the objective of the project is to quantify the share of public spaces that can be converted for other uses, thus promoting a better metabolism. In this way, the proportion of the area dedicated to the traffic of vehicles is reduced from 80% to 24%, while parking space occupies 2% instead of 8%. Green areas, pedestrian areas and cycling paths, playgrounds and water retention ponds reinvest all the recovered space and restore the metabolism of the streets. This 4 sq.km pilot zone aims first of all to make all New Yorkers aware of the potential of transformation of their streets the tech and service-geared transition of mobility.
