The ease with which people understand the layout of a place based off of recognizable patterns that exist in the cityscape (i.e. the hills of San Francisco)
68
City Planning According to Artistic Principles
- Author is Camillo Sitte
- Published in 1889
- Suggests that the quality of urban space is more important than architectural form (the whole is more important that the parts)
- Planning cannot be done in 2D, only in 3D
- Argues that the agora and forum are great urban spaces
- Fears Urbanism might become a mere technical task without any artistic involvement
- Proposed cities be laid out on the principles of medieval towns, with curving and irregular streets
- Conceived of the turbine square, which created civic spaces around a pinwheel arrangement
- Not concerned with the historical circumstances that generated old forms since urbanism is to be lived today and must be judged according to today's aesthetics
69
Kevin Lynch
- Author of the Image of the City
- Discusses a concept known as legibility/imageability: how users perceive and organize space as they navigate a city by recognizing paths, edges, districts, nodes, and landmarks
70
Camillo Sitte
- Author of City Planning According to Artistic Principles
- Criticizes the aesthetic of the late nineteenth century urbanism
- Most important belief is that architectural shape and form is not as important as the inherent creative quality of urban space (the whole is bigger than its parts)
- Proposed that cities be laid out on the principles of medieval towns to create irregularity and variety - current Urbanism was too technical, not enough artistic involvement
71
The Neighborhood Unit
- Author is Clarence Perry
- Published in 1929
- Framework for urban planners to design functional, self-contained desirable neighborhoods in industrializing cities
- Major highways and arterial streets form the perimeter, but do not go through the neighborhood
- School and community center would be at the center of the neighborhood - children would only have to walk 1/4 to 1/2 mile to get home without having to cross any major streets
- Shopping, churches, and services would be placed at the edge of the neighborhood so that nonlocal traffic wouldn't intrude on the neighborhood
- 10% of the land would be dedicated for parks and community open space
72
Clarence Perry
- Author of The Neighborhood Unit
- Established the framework to design a self-contained and desirable neighborhood in industrializing cities of the early 1900s
