OVERVIEW
The aim of this research is to investigate pedestrian behavior at signalized intersections using state-of-the-art LIDAR sensing technologies and to use this data, along with vehicular data, to develop a more effective multimodal signal control system.
In the presentation, the presenters will describe a novel method of collecting pedestrian crossing behaviors at signalized intersection, discuss the findings and implications of data analytics, and introduce a novel approach to dynamic flashing yellow arrow mechanisms to reduce the conflict between left turn vehicles and crossing pedestrians.
KEY LEARNING OUTCOMES
- Understand the framework of LiDAR sensing solutions;
- Understand how to collect pedestrian behaviors at intersections;
- Understand how to provide new protection for crossing pedestrians with object-tracking technologies.

This webinar is based on a study funded by the National Institute...

OVERVIEW
Even though there are tremendous uncertainties in the timing and evolution path of the Autonomous Vehicles (AV) technology, it may become a likely reality within most MPOs' long-range regional transportation plan horizon of twenty years. Yet a recent survey of the largest MPOs in the US indicates only one of them "even mentions driverless, automated, or autonomous vehicles in its most recent RTP". One of the uncertainties in assessing the impacts of AV is their direction: on one hand, self-driving cars could increase VMT by increasing roadway capacity, lowering costs of travel; on the other, they may reduce VMT by enabling more car-sharing, improving access to transit, eliminating the fixed costs of car ownership, and reclaiming parking space. To date, there is no suitable conceptual framework or modeling tools available to MPOs for quantitatively assessing the likely long-term effects of AV or potential policy scenarios.
This project studies the possible impacts on travel and land use of the emerging AV technology and focuses on advancing this innovative mobility option by...

Summary: Although the running of red lights is perceived by motorists as a commonplace behavior for cyclists, little research has been done on the actual rates of cyclist compliance at signalized intersections. Furthermore, little is known about the factors that influence cyclist non-compliance. This research seeks to illuminate the rates of and reasons for infringement against red lights using video footage and survey data from cyclists in Oregon.
Bio: Sam became interested in transportation and planning while studying abroad in Freiburg im Breisgau, Germany. After benefiting from the efficient transit service and excellent walkability there, he came back to the states with a gusto for safe, efficient, and environmentally sustainable transportation. After finally figuring out what to do with his Civil Engineering degree, he enrolled in Portland State. Sam's research interests include cyclist behavior and the comprehension and safety implications of new infrastructure. Originally hailing from Kansas, he has grown weary of Wizard of Oz jokes but is otherwise happy to call Portland his home, especially with the abundance of good coffee, micro brews, and stellar pie that PDX has to offer.

Topic: Inaccessible Accessibility: low-income households and barriers to the “new American dream”
In many ways, the resurgence in demand for housing in highly accessible and walkable neighborhoods can be viewed as a triumph of planning and policy efforts to reinvest in walkable urban neighborhoods that support active travel. However, increased demand has resulted in price premiums that can make location-efficient housing choices more difficult for low-income households. This research uses data from a survey of recent movers in six U.S. cities, including Portland, to explore the extent to which households of different economic means are able to choose housing locations that match their accessibility and transportation preferences.
Bio: Arlie Adkins is a PhD candidate and adjunct instructor in the Toulan School of Urban Studies and Planning at Portland State University. His dissertation research focuses on better understanding how people make decisions about non-work travel behavior in the context of a new home. Arlie holds a master’s degree in city planning from UC Berkeley. He previously worked in TriMet’s project planning department as a community affairs specialist and at Flexcar in Washington, DC.

OVERVIEW
This webinar will introduce you to the concept of the Community Transportation Academy (CTA), a model which has been operating in Portland for over 30 years in the form of the Portland Traffic and Transportation (PTT) class. Now catching on in other cities, the project team recently implemented the Wasatch Transportation Academy (WTA) in Salt Lake City. The presenters also include key stakeholders (and guest lecturers) in the WTA, and the PTT instructor. The presentation will include discussions about why CTAs can be good for both community members and transportation agencies/practitioners, and how you can bring a CTA to your city.
KEY LEARNING OUTCOMES
- How to make interactions between community members and transportation agencies more effective
- How to increase human capital and community capacity by teaching community members how and where they can engage in transportation decision-making processes
- Lessons from transportation...
