Episode Description: In this episode of Location Matters, host Nick Chai is joined by Oliver Looker, Director of Transport and Smart Cities at NGIS, to talk about what it actually takes to measure road congestion across an entire city. The average person living in a major Australian city loses around 80 hours a year to traffic, and building more roads is rarely the affordable answer. Oliver explains how TraceMark Flow turns Google’s Road Management Insights data into something transport agencies can work with, refreshed every two minutes and covering a whole city or a whole country without putting a single new camera or sensor in the ground. He also covers how the approach compares with SCATS and inductive loop sensors, where AI fits into predicting the effect of storms and big events, a case study from Thessaloniki that measured a 40% travel time impact from a major road project, and why the congestion an agency knows about is often not the congestion costing it the most.
