The transportation sector is rapidly changing due to changes in vehicle, communications, and sensor technology. Given these changes, how can universities develop these new technologies to address mobility, accessibility, energy, environmental, and equity issues?

Portland State has a newly established center to explore these very issues. The Digital City Testbed Center is here to create research and development partnerships with cities, firms, and non-profits to develop and test new technologies. Check for more updates soon.
