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...

Integrate Socioeconomic Vulnerability for Resilient Transportation Infrastructure Planning
Liming Wang
John MacArthur , Yu Xiao
This research project develops a novel methodology for assessing transportation network vulnerability and resilience, with a particular focus on incorporating social vulnerability into the analysis. The study addresses a critical gap in existing research by integrating socioeconomic vulnerability indicators into the evaluation of transportation infrastructure vulnerabilities for areas facing multi-hazards, using the Portland metropolitan area as a case study.
The methodology combines spat...
