While my project will focus more on what is indicated in orange  as the approximate area of the interchange, there will be a secondary component of the thesis at a larger urban scale. This component will begin to illustrate the beginnings of an emergent system of networks.  For this portion, I plan to use the abandoned subway tunnel [seen as red dotted line] as a distribution spine from the transit interchange.

I have been experimenting with Grasshopper to help demonstrate some distance mappings of possible routes to and from random points.  My second attempt to use the GH component “Shortest Walk” yielded some helpful results.  The idea is to visualize the existing subway tunnel as a spine that extends eastward from the interchange and towards Rochester’s downtown.  I used a measurement of 1/2 mile as the walking tolerance so see all the possible routes one would take from the tunnel path outward.  This GH definition is a simplified version of what may come in the near future.  I intend to incorporate other disruptions or attractions within the city’s downtown to model the more complex nuances of movement.

The US Census Bureau’s website is a labyrinth of useful data and is unnecessarily difficult to navigate.  Fortunately for us, NYTimes decided to help us out by visualizing the mystery information from the American Community Survey.  They’ve translated data into easily comprehensible maps and diagrams like many of their past data representations.  Take a look here and have fun exploring: http://projects.nytimes.com/census/2010/explorer.

Here is a closer look at Rochester [click on the image to enlarge]:

Racial distribution | racially segregated [blue dots=black; green dots=white]

Income distribution | the lighter the blue, the lower the income

Change in Median Income | the darker the blue, the higher the decline

As parking areas begin to cluster based on proximity to each other, the shortest distance is mapped to the subway tunnel. This process starts to reveal potential hotspots for interventions.

These animations show further development on the Grasshopper models seen from a previous post.   By using the proximity component [in green], I am able to create an animation mapping distances among the various parking areas to each other.  This allows us to see where clusters begin to appear/form and perhaps become potential opportunities for interventions.

The field of parking lots [outlined in red and green] spread throughout downtown Rochester prompted a Grasshopper [GH] exploration on their relationships to two corridors: the abandoned subway tunnel [shorter segment] and the Genesee River [oriented north-south].

Based on the size of each parking lot [green outlines are parking garages], points are positioned from the center of each shape while its Z-value is a factor of each individual footprint.

A modified voronoi surface creates a terrain based on parking lot sizes in top and perspective views.

After creating the 3D landform, I took perpendicular sections along each corridor to describe its relationship to the distribution of parking area.  The first set of 3 images describes the conditions along the abandoned subway tunnel.

Flattening these sections would probably help illustrate more clearly the variation in area distribution or parking [potential usable] availability along the corridor.  That will be for another time.

The following 3 images are of sections along the Genesee River.

I spent a little time trying to create a 3D diagram of my thesis through Grasshopper.  It’s in its early stages and should evolve into something more complex.

Rochester’s layers of infrastructural networks illustrate a complex history.  As I dissect the layers both in time and by system, I hope to reveal an underlying structure significant to Rochester’s current and future development.

These Grasshopper animations begin with tracing the 1892 paths of the river, canal and railroad.  Each system is then  divided into equal segments with a voronoi diagram attached to each division point.  As the number of divisions increase, the amount of system’s influence also became more clear.  The next step is to merge the 3 networks and study their interactivity.

My thesis research will, for a good first part, involve explorations in mapping methodology.  I recently came across the following publication where the current issue is on the topic of INFORMATION and various ways designers/artists have used visual means to communicate data.

How can I  use parametric technology to help visualize information and communicate my ideas?

Earlier in the year, Eric Fischer gave us maps of Geotaggers’ World Atlas.  Now, he’s introduced a new series on race and ethnicity of cities across the globe.  The one below is of New York City.

_Blue = Black

_Green = Asian

_Orange = Hispanic
