Research Highlights

Implementing Oregon’s Energy Plan: Opportunities for Operations and ITS

Jon Makler
Oregon’s 10-Year Energy Plan identifies intelligent transportation systems (ITS) as a key strategy for reducing energy consumption in the transportation sector. Other strategies, including fleet turnover, will take a look time to realize benefits for the state while ITS can be implemented and produce results sooner. This project’s goal was to identify operations/ITS opportunities whose near-term implementation or acceleration can aid the accomplishment of the energy plan’s goals. The research... Read More

Statistical Inference for Multimodal Travel Time Reliability

Avinash Unnikrishnan
Miguel Andres Figliozzi , Subhash Kochar
Travel time reliability – or the consistency and dependability of travel times from day to day, and at different times of day – is a key metric that significantly affects people’s travel behavior. Since businesses rely heavily on transportation systems, an unreliable transportation network can also impact the economic competitiveness of urban areas. As such, reliable travel times are important for transportation agencies to promote economic stability within a community. Having accurate method... Read More
