Improving Walkability Through Control Strategies at Signalized Intersections
Sirisha Kothuri
Christopher Monsere
The goal of signal timing at an intersection should be to separate conflicting movements in time, maximizing safety and efficiency for all users. In many jurisdictions, however, signal timing objectives have traditionally focused on allowing vehicle progression and reducing vehicular delay and stops. While these are important considerations in many contexts, other users (especially pedestrians) deserve similar focus and control strategies. Recent updates to the Highway Capacity Manual (HCM 20...

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...
