DRIVE-LESS LIFE The transportation sector alone contributes to 36% greenhouse gas (GHG) emission in New York State, and approximately 70% of which comes from private vehicles.Extensive highway networks, deficient infrastructures for mass transits, suburban lifestyle all facilitate a culture of car dependency and contribute to the amount of GHG emission.

To decarbonizing the transportation system in the region and meeting the goal of net-zero, we propose a hybrid system with three target design solutions while taking Poughkeepsie as a pilot site.

1. An Emission-Free Shared Vehicle system combines

+ Project Site Poughkeepsie

a network of smaller shuttles and a fleet of shared autonomous electric vehicles to replace the existing bus network with more flexible and frequent services.

2. Improve public transportation infrastructure by building new bus stops integrated with public space and urban life.

3. Remove the elevated Route 9 Highway in front of the Poughkeepsie train station to redesign the route as

MANUFACTURING PUBLIC SPACES The Industrial Business Zone in Long Island City is located in the heart of New York City. However, because the area is severely disconnected to the cityâ€™s mass transportation systems, including subways, and buses, the IBZ has also been disconnected from the local communities.

Manufacturing Public Space is an urban design proposal that attempts to using streetscapes to revitalize the IBZ for mutual benefits of the industries and local communities. The design strategies include protecting the industries and businesses in the IBZ; then, reconnecting the IBZ to the local communities, while improving the built environments of IBZ. Though designing integrated public spaces, the project attempts to reconnect the IBZ with local communities, and improve the quality of living and working for both the local residences as well as workers.
