(Portland, OR) -- Mayor Ted Wheeler is expected to issue an emergency order as early as today banning all homeless camps that are located along dangerous roadways. The order follows release of the city's annual traffic crash report that shows 70 percent of all pedestrians killed in Portland traffic accidents were homeless residents. The Oregonian first reported on the study. The city had planned to open six Safe Rest villages for the homeless by the end of last year but the plan was pushed back to later this year.
