THE RIVER BECOMES A PUBLIC SPACE

Greywater from the public restroom units that hover the scooter stations refuels the scooters. These public restrooms also have multi-functional qualities such as resting and showering.

On the water, a new type of public space is rendered: the images of the fueling of environment that emerges from this new transportation network.

WATER FUEL: A Water-Fueled Scooter Network. Silo & Studio Marsman

An alternative to commuting by car in street traffic and crowded subways in Manhattan, the Water Scooter Network proposes a way for individuals to travel in the city through a water-fueled system of shared scooters. With fueling mats floating on the water, a new form of public infrastructure comes into play. Electrolyzers act as heating sytems in each of the fueling units along the mats, introducing possibilities of recreation such as heated pools and barbecue pits powered by the water-hydrogen technology of the mats. At the street scale are refueling stations, where public restrooms can attach to existing street elements such as streetlamps and bollards while hovering over parked scooters.

A closer look at transit environments in the city, specifically along Market Street, a major road for not only automobile and transit traffic but bicycle and pedestrian traffic as well. The Street Inventory highlights common elements found in current station-street intersections.

WALK/BIKE

With the majority of the traffic congestion located in the neighborhoods of Downtown San Francisco, SoMa, and the Financial District, Market Street remains one of the most congested and transit-heavy streets in the city. Job density and accessibility, along with population, is also the greatest in this corner of the city (see following page). Transit crowding is greatest in travel in this area as well. Trip patterns also point toward a large portion of travel occuring to and from downtown San Francisco, both in public transit as well as pedestrian and bicycle travel. Pedestrian injury studies also show that while most congested, these specified areas in the city have less risk than elsewhere around of the city. For the most part, there exists more risk for pedestrian injury in areas that are less transit-heavy with no lightrail lines going through or nearby. With the amount of multimodal travel alternatives to the automobile, streets such as Market Street and other areas of heavy transit use should meet the needs of travelers and integrate the street to accommodate for the growing population of future transit and multimodal commuters.

Current street conditions in transit environments consist of the same elements throughout the city. However, most of these elements lack the capacity to accommodate the needs of city commuters. Common street elements, such as the streetlight, are used as static leaning spaces for travelers wanting to sit and wait. Trees have become spots for scooters to lean on. There is a lack of public space in these areas, with little space to wait or store bicycles for those who travel multimodal. Analyzing the street in transit environments calls for the introduction of alternatives that work for the people and combine functionality with

The Site.

Located in SoMa, San Francisco, Hallidie Plaza is currently serves as a connection to the Powell Street transit stations in the city. The plaza is divided on the street through a tunnel. Since the site is a significant access a 16’ deep sunken plaza that Street Station, one of the busiest street level and connected below access point for tourists and residents alike, there is a lot of activity flowing in and out of the plaza. The tunnel consists of a Visitor Information Center, scheduled to move to the Moscone Center a few streets away. Adjacent to the site is the Westfield San Francisco Centre, the historic cable-car stop, and an abundance of retail, restaurant, and hospitality spaces nearby.
