Research Highlights

Understanding Factors Affecting Arterial Reliability Performance Metrics

Avinash Unnikrishnan
Sirisha Kothuri
With worsening congestion, travel time reliability is increasingly becoming as critical as average travel times in affecting travel choices. This research project will first study the data requirements for existing travel time reliability metrics being used or being considered for use by practitioners and researchers. The research team will then use bluetooth travel time data from arterial corridors in Portland to get an understanding of the temporal variation in travel time reliability metri... Read More

Inclusive planning to evaluate improved non-emergency medical transportation services for patients with End Stage Renal Disease

Jenny Liu
The objective of the project is to evaluate the effectiveness and efficiency of non-emergency medical transportation services (NEMT). The first objective of this project was to design a framework that could be used to evaluate the effectiveness and efficiency of non-emergency transportation services (NEMT). In addition to the development of the framework, this project aimed to establish connections between Portland State University (PSU) researchers with regional connections involved in publ... Read More
