Roads, Bridges & Transport
📋 What it is
Transportation networks move people and goods; good networks are connected, redundant, and match how people actually travel.
🗣️ Coach says
A city lives or dies by how people move. A good network connects everywhere, offers backups when one route jams, and mixes walking, transit and roads. Bad transport = a city stuck in traffic; good transport = a city that flows.
🧠 Memory hook
Connected + backup routes + right mix = a city that flows.

Why did the skyscraper break up with the parking garage?
The relationship had too many levels!
😲 Whoa!
A single city bus can replace roughly 40 cars on the road — mass transit is a giant traffic-and-space saver.
✅ Quick check: Why is it risky for a city to depend on just ONE bridge or road into a neighbourhood?
Say your answer out loud first — then reveal.
If that single route floods, breaks, or jams, the whole area is cut off — networks need backup (redundant) routes.
Redundancy is a core systems idea that transfers far beyond roads.
