The Portland Bureau of Transportation has published its first-ever manual for temporary traffic control designs. Wonky words aside, this new guide is an important tool that could lead to safer cycling (and walking and driving) through work zones.
The guide has been endorsed by Portland’s City Traffic Engineer Lewis Wardrip and is aimed at designers, engineers, utility and maintenance workers, and even astute tactical urbanists (wink wink). Chapters include comprehensive lists of pertinent laws and city code/permitting requirements, recommended devices and products to get the job done, and how to train flaggers and traffic control measures.
