Podcast #13 of Adelaide (un)Planned takes on transport planning with engineer and economist Scott Elaurant, as Michael and Daniel seek out the dark secrets of traffic modelling. Is something wrong with the models, or is it just the way we use them? And when did project managers take over from traffic engineers as the bogey men of urban decision making? The team also talk about Adelaide's bus reforms (!), and learn why the French build the best light rail.
