Narratives of Marginalized Cyclists: Understanding Obstacles to Utilitarian Cycling Among Women and Minorities in Portland, Oregon
Amy Lubitow
Everyday cycling for transportation can have positive, population-level health impacts. Significant deterrents to cycling remain, however, particularly for women and minorities. Narratives of Marginalized Cyclists, a NITC project conducted by Amy Lubitow of Portland State University, explores the experiences of women and minorities biking in Portland, Oregon. Lubitow interviewed 28 Portlanders who self-identified as a woman or as a racial/ethnic minority (or both), and based on the insights g...

A Decentralized Network Consensus Control Approach for Urban Traffic Signal Optimization
Gerardo Lafferriere
The main contribution of this project is the simulation platform that allows for comparison between the proposed consensus approach and a standard traffic signal control protocol. The main features of the mathematical model and the simulation tools are explained and illustrated in the report. The complete open source for the code is available in the online depository. The code is in the form of MATLAB files with extensive comments explaining the various parts of the model. The tool has an int...
