Portland State University researchers have received funding for five new transportation research projects via the National Institute for Transportation & Communities (NITC), a research consortium funded by the U.S. Department of Transportation and led by Portland State. The projects listed below have been awarded to PSU faculty along with some inter-university collaborators, and will investigate a range of topics from leveraging advanced technology to create smart transportation systems to improving universal access and equity:
Travel time reliability is a key metric of interest to practitioners and researchers. This project will evaluate and develop methods to determine confidence intervals and hypothesis tests for select travel time reliability parameters. The researchers will also study the applicability of existing travel time reliability metrics for class one vehicles (bicycles and motorbikes) and the feasibility of defining an overall travel time reliability of an arterial segment that considers all modes.
