Dan Haneckow publishes a blog on "Travel, History and Portland, Oregon" called cafe unknown.  Back in March of 2008, he posted an article about one of the city's first efforts at a motorist public safety campaign.  The article gives an insightful glimpse into our city's past and our longtime attempts to make the roads safer.

The most interesting ephemera Haneckow's published, I think, are videos taken by the Portland Traffic Engineering Bureau and the Portland Traffic Safety Commission in the 1930s.  The videos were used to evaluate new traffic control features - stoplights!
