A new post by Michael Anderson introduces the new podcast, which includes an interview with Peter Koonce, the division manager for Portland's signals and street lighting division.

The interview goes behind the scenes to explain the technical decisions that dictate the flow of traffic on Portland's streets. As the post explains, "signals have quietly become one of the most important and unique ways that Portland has made itself a better place for walking, biking and driving cars at reasonable speeds rather than at noisy and unsafe ones."
