The Transportation Podcast from Traffic Technology International is a trade publication putting questions to the people it covers. Tom Stone, editor of TTI, conducts the interviews. Saul Wordsworth, the publication's Editor-at-Large, sometimes introduces an episode by naming the guest and listing what the conversation will cover, and several episodes lead with a quick run of pulled quotes before anyone says hello. The guests include a turnpike chief, an MP, industry experts and equipment makers. Road cameras come up in several episodes. In the ghost plates debate, Sarah Coombes MP is joined by Chris Shepard of sponsor Mav Systems, and the talk turns to a camera that, it is claimed, can read the plates whether they are ghost or not. One case described there traced a car through footage back to where it was parked, and when the vehicle was found it had ghost plates on. The policy argument is practical: punish low-level users seriously, and police can concentrate on the more serious criminals. Worth knowing: the sponsor is not confined to the ad break. A separate installment, 'Episode 47: MAV System's game-changing ANPR camera', is given over to the camera, and the case for plate reading is made in everyday terms, from cars kept on driveways to dangerous parking outside schools. With Brett Ferrin of Traffic Logix, a developer of traffic calming products, the talk turns to concerns over privacy and profiteering. It also covers how US states and cities are each deciding where the technology is allowed, in some places only in school zones or work zones. Tolling gets the operator's view. Mark Compton, CEO of the Pennsylvania Turnpike Commission, is asked about open road tolling from its start to its next steps, in an episode titled 'Podcast 56: Open road tolling and integrating AI with Mark Compton, CEO of the Pennsylvania Turnpike Commission'. Someone in it calls a test site named Penn Start 'the Disney world of test sites', and it ends on a sober note, with a funeral recalled and what still keeps him up at night. Europe supplies the policy end. Three experts, among them the CEO of Ertico, discuss connected vehicles, the ITS Directive and a delegated act from 2013 that one of them suggests came before connected vehicles and connected roads existed. One voice insists the work is for the public good, not for monetizing data. Giles Perkins discusses Live Labs 2, a program spread across seven places and described as starting to publish reports on the good, the bad and the ugly of what has been learned so far. That episode is 'Podcast 55: Why EVs aren’t enough to decarbonize road travel, with Giles Perkins'. The ghost plates debate is the most direct way in, since it puts a lawmaker, a vendor and the editor on one problem. For regulatory detail, pick the connected vehicles conversation.
