Key ideas in Navigating the American Metropolis
- Older cities grew organically along old paths before modern planning
- Grids provide multiple routes but many intersections
- Newer cities were often mapped out all at once on flat, open land
- Why older East Coast cities have irregular streets compared to Midwestern ones
- Sprawl limits through-traffic but creates confusing dead ends
- The trade-offs between grid and sprawl layouts
- Grids prevent traffic from bottlenecking on a single main road
- Curving streets were designed to mimic a park-like, rural feel
- Sprawl forces all neighborhood cars onto one or two 'collector' roads
- Cul-de-sacs were intended to keep through-traffic out of residential areas
- How street patterns affect traffic capacity
- What a sprawl layout reveals about original land use
- Early growth followed natural terrain and animal trails
- Mid-era growth focused on industrial and commercial efficiency
- The typical evolution of a city's street pattern over time
- Natural obstacles like steep hills or rivers force the grid to bend
