Freight travel-time reliability
Most supply chains cannot thrive without access to an efficient and reliable freight system. Since congestion in the highway system has a significant impact on the productivity and competitiveness of the Pacific Northwest Economy, the objective of this research is to evaluate travel time reliability in the main freight corridors connecting the Pacific Northwest to California, the Midwest, and Southwest.

How well do bike boxes at intersections work?
While bicycle commuting has increased 145 percent over 10 years in Portland, many residents limit their cycling because of traffic safety concerns. Most crashes happen at intersections, many as vehicles make right turns into cyclists. Portland’s bike boxes were designed to address this problem. Portland State University’s Jennifer Dill and Chris Monsere looked at the bike boxes’ potential to reduce conflicts and measured drivers’ and cyclists’ impressions of the traffic control devices, which hadn’t been used widely elsewhere in the United States.
