What invisible system decides the fastest route on your phone, the best place to build a fire station, and how cities respond when a water main breaks underground? In this episode, we take a deep dive into transport network analysis and uncover the hidden mathematical logic that quietly organizes modern life. What looks like everyday movement through roads, pipes, rails, and digital infrastructure is actually governed by a powerful framework of nodes, edges, costs, capacity, impedance, and flow that turns the physical world into a solvable graph.

This transcript explores how the field began with Euler’s Seven Bridges of Königsberg problem and evolved into the modern GIS systems that power GPS apps, route optimization, delivery logistics, public utility monitoring, and urban planning. Along  ...
