As American metropolises continue to grow, traffic increases, and capitalization of these areas often leads to gentrification. In order to address this, growing cities gradually become more dense.

Many types of programmatic spaces and circulation types of pedestrian, bike, vehicular, and train overlap at large train stations. Today in the U.S., many stations do not yet match the scale of other stations in other cities simply due to

differences in use, density, and popularity.

Many Americans still prefer to travel by the faster car or motorbike. In light of America’s planned advancements in vehicular technology, the need for housing such transportation increases. Future stations grant an opportunity to serve as

The Station & The City

In order to understand how a with increased pollution, loss of amenity station evolves, one must understand why a space and reduction of privacy” (Frey, pg. station evolves. Over the years the station 331 1999), Frey recognizes that there has manifested as a result of advancing are still supporters for “decentralized technology and the growth of the concentration”.

Cities will grow, and there must be an answer to accommodate this growth.

Issues include the transition between urban and rural communities, social segregation, and centrifugal fragmentation. One answer may be the decentralized concentration of the city, focused around social hubs to encourage interactions within.

Despite arguments that say “The compact city would cause congestion,

part of regionalization and globalization of the world and on new temporal relations in the division of labour and the everyday.”

The creation of multiple points of concentration “[increases] the density of the centers of our cities, where business affair are carried on”(Corbusier, p. 70, 1999), encouraging development of central points in the city through capitalism. The development of new centers, accommodates population growth of the city and within

Even though some state that “The compact city policy would result in the neglect of rural communities and earlier growth centres which emerged under dispersal policy.; the rural economic

This would add to

Melbourne is a prime example against Frey’s (pg. 331, 1999) argument, in which the compact city did not “result in the neglect of rural communities and earlier growth centers”, but the city was able to live and grow harmoniously with the development of the city.

Jane Jacobs (pg. 150, 1961) states that there are four conditions to generate

diversity; mixed use, “opportunities to turn corners,” buildings varying in age, and a

“dense concentration of people.” These conditions don’t only apply to city plans, but large projects as well. One project that seems to cover all these conditions is

Kyoto Station in Japan. Kyoto’s dense

concentration of people makes a large station essential for commerce in a city

enriched by history and culture. At roughly

2.5 million square feet, this station offers many corners horizontally and vertically creating an array of opportunities. It’s mixed use only adds to the appeal;

leads me to believe that in order to

successfully develop a city, one must encourage private enterprises to invest

in the populous in building not only out, but up as well perhaps in conjunction with other enterprises.

This approach makes use of large funds in a top- down approach to benefit the both the masses and the individual.

In this book, the quality of life is defined, not unlike other written articles, as safety, health, and environmental quality. Lefebvre (p. 49, 1996) suggests that “we could develop an analysis on time and space, from the positioning of the body

of life. In order to implement these

elements according to the body’s public and private, wants and needs, multiple centers are required to provide ample space and

prevent haphazard planning. In this manner, the implementation of a polynucleic plan does not seem so far off in the future.

In the past, Frey (p. 335, 1999) has noted 3 compact city plans in which the first represents “large concentrated centres”, the second represents “decentralized but concentrated and compact settlements linked by public transport,” and the third “dispersal in self-sufficient communities”.

community neglect, social segregation, and overall quality of life can be addressed by simultaneously growing up and out from central interactive points of society in sphere-like shapes. It is important to

emphasize that these central points are not dense populations of a single city center, but instead areas defined by society to have importance among the interactions of everyday life.

The main source of

circulation would be through city centers, like

Frey’s ideas, but it is important to note

that this plan would not emphasize mass transportation systems from center to

center, but rather the minor circulation that determines the transition from center

to center; the overlap of unique conditions within influential spheres.

This transition

space is integral in the public private interface and could in turn define the city center.

For example, looking at Melbourne, to the city, and states that it invariably the Yarra River runs along the edge of “depends upon… centrality”. In creating city center. This river like many cities multiple centers we give the city back to determined the original grid layout of the its closest inhabitants, and maintain the city at its establishment. It is a natural circulation and ease of access through border, and it’s existence presents the center by shortening travel distances conditions for social interactions (like both horizontally and vertically. Already festivals) and capital gain. It is a condition as a social center people gravitate towards to recognize Pallasmaa’s eyes of the skin these centers, creating a sort of rippling where “experience” would be “moulded by geocentric pattern that radiates outwards hapticity and peripheral unfocused vision.” not only in one plan horizontally but (Pallasma, pg. 10, 2005) also vertically. The nature in which these By creating a nucleus the urban circles radiate outwards depends on the fabric becomes de-centralized and people and their interactions with the rapid growth is relocated to a more surroundings, including other centers. accommodating area, and we give the city Likewise, Howard (p.347, 1898) back to its inhabitants. We create multiple points out that “it is at once seen that points of interest or “attraction” (Howard, nothing short of the discovery of a method p. 347, 1898) much like Howards Garden for constructing magnets of yet greater City. Lefebvre (p. 195, 1996) contributes power than our cities possess can be the overall success of the city, the effective for redistributing the population “[appearance] on all the networks and in a spontaneous and healthy manner.” circuits of communication, information, By creating various points of interest at and exchange,” to the citizens rights each center with more frequency, not

unlike Jane Jacobs idea to open up the neighborhood block, we distribute the power within our cities.

The points of interest are the “foci” Schultz (p. 151, 1979-1980) speaks of and are more or less organically determined by the social spheres of society.

This is evident in Alexanders observation of housing, or the combination thereof.

The above. This sense of organization can

also lend to the avoidance of interaction entirely and consequently develop social

segregation. In the case of the apartment complex, unless there is a rooftop deck

or other function above ones room, what purpose is there to take the elevator

further than your apartment floor? If we were to mix the program vertically as

well as horizontally, we would essentially raise the ground plane, allow access

to a wider range of people, and create

opportunities for business. As Lozano (p.

316, 1990) says “the greater the number and variety of urban activities, the richer the life of a community; thus urbanity is based on density.â€? Private living quarters would remain among the vertical façade, but they may also be closer to a coffee shop, and a walk away from the nearest public transport.

This vertical stacking could be related to Le Corbusiers idea of circulation as well, by providing new entrances vertically we provide reason and opportunity for new avenues of raised

circulation decreasing traffic congestion.

Climate: warm-summer Mediterranean climate characteristic of California’s coast, with moist mild winters and dry summers. San Francisco’s weather is strongly influenced by the cool currents of the Pacific Ocean on the west side of the city, and the water of San Francisco Bay to the north and east. This moderates temperature swings and produces mild year-round climate with little seasonal temperature variation.

The scale and density requirements of stations change based on location and needs. Some stations exclude amenities altogether. As technology advances we may find that circulation becomes more straightforward, and there are ways in which one can bypass systems currently in place; for example digital ticketing.

Design 62

Design Goals: • Reactivate historic Union Staiton with additional amenities updated efficient transportation, and an inviting atmosphere • Energize the station and new technology with renewable resources such as PV and kinetic floors.

• Explore. Create open public areas, such as viewing platforms, where people can linger, wander, and visually explore to satiate the visitors impressions of Los Angeles.

A Few Assumptions: • Public transportation will be more reliable • Public transportation will run on time • With the invention of Autonomouse Vehicles the ability to go from place to place wil be more direct and mainstream. Union Station’s current infrastructure does not support such vehicular traffic, and thus the current historical building will be but a historical ornament (much as it is already) to add to the mixed use and culture of LA. •

Nature’s Application Bio- Thought Experiment Figure 4.1

77 Circulation

Slime Mold |

Problem: How do we determine the best path of circulation?

Solution:Slime mold reflects “swarm intelligence” in which the mold can effectively travel from point A to point B in the quickest possible route with great efficiency. Other routes away from the most efficient are retracted. The mold “remembers” where it’s been by leaving a trail behind. Like the human population, the mold grows and disperses in search for more resources using minimal energy.

Application: This mold is already being used to track train routes, and has nearly successfully replicated the Tokyo Rail Network based on the locations of stations. On a smaller scale, could this experiment reflect circulation on site? Could it work vertically?

Hissing Cockroach

Pollution

|

Problem: In the case of a transit hub, how can we reduce air pollution on site produced from urban environment and vehicular traffic?

Solution: The Hissing Cockroach both creates and filters carbon dioxide within it’s body. Like buildings,the hissing cocroach respiratory system consists of a unidirectional airflow, in which clean air is brought in at one location and spent air is released at another. Thoracic pores collect internal spent air and release it externally allowing airflow in one direction preventing backflow.

Application: Parallels can be drawn between the thoracic pores of the hissing cockroach and an interior space in which spent air can be passively collected, and then filtered before being released to the exterior.

Figure 4.3

Elephant Seal

|

Water

Problem: In an arid environment where water is scarce, how can capture water and minimize loss?

Solution: The Elephant Seal has a trunk like nose in which boney structures called nasal turbinates maintain bodily water levels. The function of these nasal turbinates cools warm air exhaled from the Elephant Seal, lowing the dew point and condensing water along the nasal passages as it exits the body.

Application: My mimicking the structure of nasal turbinates water can essentially be captures from moist/ humid heated air and dewpoint can be lowered to capture water within the same system.

Flow of Sitting

MATERIALS + TECHNIQUES

Movement varies in both growth and scale.

In order to create an environment suitable to movement one must understand how people move and why, or the flow of human movement.

In this study, the Flow of Sitting attempts to encourage movement in solid wood through kerfs, or cuts meant to purposefully weaken the integrity of the wood, just enough to bend under stress without breaking. Like a crowd pushing through narrow walkways, pressure builds, but is accounted for in an adjacent space encouraging movement. The organization and

structure of these kerfs creates its own kind of 79 dynamic rhythm as a result of accounting for stress. As such the pattern varies to account for where people move the most; cuts are further apart in the seat to account for a larger load while they are closer together in the backrest to promote a wider range of motion in the upper torso to shoulders. Moments of tensions are located where the user applies pressure. The form of the seat and backrest are then meant to be formed by the body.

For this experiment I tested a number of cutting techniques and woods before settling on this combination. I found that I wanted to cut perpendicular to the grain to allow enough range of movement without too much pressure, and in contrast the wood was more likely to splinter or snap when cutting parallel to the grain. Likewise cutting perpendicular to the core of the wood allowed for the least amount of flexibility, but was too rigid. Cutting perpendicular to the core of the wood was also not ideal as it meant buying wood in long lengths, which was not always available.

The width and depth of the cut also created parameters for the range of motion that the wood could withstand. For this experiment I used 1/8” wide table saw for the cuts.

Depending on the flexibility of the wood a thinner blade or CNC would have been more ideal in order to create more control and support in the motion of the wood. In contrast to my precedent, Carolien Laro’s “Spring Wood”, whenever I overlapped cuts the wood had a tendency to break towards the adjacent cut. With my weight of 140 lb. I could sit on cuts as deep as 7/8” deep on both sides of a 2” piece of wood with great flexibility, however someone with a weight of 150 lbs. would break this, thus I ended up settling at ¾” deep cut on both ends of a 2” piece of wood which allows anyone up to about 200 lbs. to sit on it though it is not as flexible to those who weigh less.

FRAME

In addressing the material, I took precedent again, from Carolien Laro’s “Spring Wood” stool which also flexes using kerf patterns. In her project she uses Ash wood. I tested Doug Fir, plywood, and ultimately settled on Ash as well. During this testing I found that with an elastic modulus of 1,765,000 lbf/in2, Doug Fir snapped too easily. Plywood with minimal cuts and basswood were too flexible. Ash wood has an elastic modulus of 1,360,000 lbf/in2, and thus Ash wood does not snap as easily and is more flexible than Doug Fir, but less flexible then plywood and basswood.

In order to support this flexible seat and back, a rigid frame was necessary, however the joints ultimately had to allow for motion. To create this twisting motion I went with 3/8” round solid steel rod that I would bend, weld, and cut so that the wood could sit and rotate on at least one axis of motion. This axis of motion becomes a part of the design following the kerf cuts along the wood. This round rod is present throughout the project to create a cohesive and supportive design.
