Portland Metro: How Much Travel-Time Reliability Matters

Friday, February 27th, 2015
Figure 1.1. Overall model framework.

More than 10 scenarios were identified and modeled in this project. The analysis results indicate that both bus rapid transit and variable message signs contribute to improved reliability for the Southwest Corridor when the performance over multiple modes and facilities is being considered. Bus rapid transit contributes to improved corridor performance by increased ridership due to higher reliability, and variable message signs contribute to improved corridor reliability by balancing the arterial and freeway flow via information dissemination.

Racial Bias in Driver Yielding Behavior at Crosswalks

Friday, May 23rd, 2014

Minority pedestrians are more likely to be killed in a motor vehicle crash even after controlling for increased traffic exposure in urban areas, socioeconomic status, and alcohol use (CDC, 2013). One potential and unexplored contributing factor to these disparate outcomes is whether driver behavior differs toward pedestrians by race. Similar to other types of intergroup interactions, roadway interactions between drivers and pedestrians are likely influenced by drivers’ subtle racial attitudes and biases. The current study focuses on pedestrians’ street crossings, as pedestrians are most vulnerable when crossing traffic lanes.
