In this episode of the Grand Parade Matt Stickland sits down with Wes Marshall, the author of Killed by a Traffic Engineer.

His book is a meta analysis of traffic engineering studies, and he tells Matt how to determine if Halifax's traffic engineers are doing a good job.

Just one note: In the episode Matt says that the HRM has made it's traffic impact statements better, and Wes points out that if they were an improvement they would consider safety. The good news is that the new traffic impact statements consider non-car modes of travel, but only consider safety in the context of car on car collisions. Not driver vs pedestrian. There's still a long way to go before Halifax's traffic impact statements are good, even if they are slightly improved from 2017
