Webinar: Words Matter: Recognizing And Addressing Modal Assumptions To Shift Transportation Culture, Barb Chamberlain Feb 2019

Webinar: Words Matter: Recognizing And Addressing Modal Assumptions To Shift Transportation Culture, Barb Chamberlain

TREC Webinar Series

Search #DriverNotCar or #CrashNotAccident on Twitter and you’ll find a vigorous discussion about the power of word choices to shape our understanding of what happens on the street and who’s responsible. When we directly examine and discuss the language we use, we acknowledge its power both to reflect existing attitudes and to shape developing attitudes. This presentation will uncover embedded biases or assumptions in common transportation terminology and provide tips and tools to help us broaden our inclusion of everyone we are supposed to serve as transportation professionals.


Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang Jan 2019

Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang

TREC Webinar Series

Although connected vehicles (CVs) will soon go beyond testbeds, CVs and human-driven vehicles (HVs) will co-exist over a long period. Hence, it is critical to consider the interactions between these two types of vehicles in traffic flow modeling. In this study, we aim to develop a macroscopic model to understand how CVs would impact HVs in the traffic stream. Grounded on the second-order traffic flow model, we study the relationships among flow, density, and speed by two sets of formulations for the groups of CVs and HVs, respectively. A set of friction factors, which indicate CVs' impact to HVs, are …


Webinar: Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri Oct 2018

Webinar: Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri

TREC Webinar Series

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.

Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies …


Trec/Oapa Webinar: Authentic Community Engagement, Eryn Kehe, Wendy Serrano Aug 2018

Trec/Oapa Webinar: Authentic Community Engagement, Eryn Kehe, Wendy Serrano

TREC Webinar Series

This webinar will provide practical tools for designing effective and authentic community engagement for transportation projects. Too often, we can forget to ask ourselves who, what and why for our engagement processes. Authentic community engagement requires us to think through exactly why we need to involve the public, how they can influence project decisions and who the most impacted people may be. This session will walk you through the steps to plan a unique engagement approach for each project and share examples of what can happen when these tools are used correctly and what can go wrong when they are …

Webinar: Tools And Techniques For Teaching Collaborative Regional Planning And Enhancing Livability And Sustainable Transportation In Gateway & Natural Amenity Regions, Danya Rumore

TREC Webinar Series

Small towns and cities outside of national parks and other major natural amenities throughout the western United States are becoming increasingly popular places to visit and live. As a result, many of these gateway and natural amenity region (GNAR) communities—including places such as Jackson, Wyoming, and Moab, Utah—are facing a variety of “big city” issues, such as severe congestion, lack of affordable workforce housing, and concerns about sprawl and density. This webinar will introduce the planning and transportation concerns being experienced by GNAR communities throughout the west. It will then share the tools and resources developed by the University of …

Drawing from notable practices, public outreach, and field analysis from multiple US …


Webinar: The Effects Of Demand-Responsive Parking On Transit Usage And Congestion: Evidence From Sfpark, Nicole Ngo Sep 2017

Webinar: The Effects Of Demand-Responsive Parking On Transit Usage And Congestion: Evidence From Sfpark, Nicole Ngo

TREC Webinar Series

Parking is a serious issue in many urban areas, especially those experiencing rapid population growth. To address this problem, some cities have implemented demand-responsive pricing programs, where parking prices vary depending on the occupancy rate in a previous period. Yet, few empirical studies have rigorously evaluated these programs. In this study, we investigate the impacts of SFpark, a demand-responsive pricing parking program in San Francisco that began in 2011. We observe effects on three important aspects of urban transportation: parking availability, transit bus ridership and congestion. The timing of this program is plausibly exogenous to factors that affect these outcomes …


Webinar: Breaking Barriers To Bike Share: Insights On Equity, Nathan Mcneil, Jennifer Dill, John Macarthur Aug 2017

Webinar: Breaking Barriers To Bike Share: Insights On Equity, Nathan Mcneil, Jennifer Dill, John Macarthur

TREC Webinar Series

While the number of public bike share systems in the United States grew considerably in recent years, early evidence indicated that many systems were not serving the diverse populations of cities, particularly lower-income residents and people of color. Lack of bike share stations in neighborhoods with people of color and/or lower incomes is one factor; however, considerable disparities appear to persist even when stations are placed in these communities.

Efforts to overcome access and use barriers (such as cost, payment options, and familiarity with the system) to bike share for underserved communities have been initiated in a number of cities. …


Webinar: Developing Practical Dynamic Evaluation Methods For Transportation Structures, Charles Riley May 2017

Webinar: Developing Practical Dynamic Evaluation Methods For Transportation Structures, Charles Riley

TREC Webinar Series

Deteriorating transportation infrastructure is constantly in the news. Government agencies at all levels are pursuing methods to monitor structural health, so that they can prioritize repairs. In Oregon, the Cascadia Subduction Zone megathrust earthquake looms as a significant natural hazard for which our transportation network is ill-prepared. The Oregon Department of Transportation (ODOT) estimates that it will take around $2.6 billion over seven years to repair or replace many of the existing bridges in the state’s network to maintain lifeline routes after a Cascadia event. Funding for the scenarios envisioned by ODOT is not forthcoming, and the project …


Webinar: The Association Between Light Rail Transit, Streetcars And Bus Rapid Transit On Jobs, People And Rents, Arthur C. Nelson Nov 2016

Webinar: The Association Between Light Rail Transit, Streetcars And Bus Rapid Transit On Jobs, People And Rents, Arthur C. Nelson

TREC Webinar Series

What are the job, residential development and market rent outcomes of Light Rail Transit (LRT), Streetcar Transit (SCT) and Bus Rapid Transit (BRT)?

LRT, SCR and BRT investments are spreading rapidly across the country but there is scant evidence of their effect on where people work and live, and effects on market rents as an indicator of value. This webinar will summarize several years of NITC-sponsored research into development outcomes associated with these transit investments. The webinar will be led by NITC researcher Arthur C. Nelson who was the principal investigator of two projects: Do TODs Make a Difference? and …


Webinar: Evaluation Of An Electric Bike Pilot Project In Portland, Oregon, John Macarthur Apr 2016

Webinar: Evaluation Of An Electric Bike Pilot Project In Portland, Oregon, John Macarthur

TREC Webinar Series

Oregon, and Portland in particular, is internationally known for its love for bikes. Not only does the region have some of the highest bike ridership in the nation but the Oregon bike manufacturing industry is quickly growing as well. Oregon’s electric bike (e-bike) market is also growing, but little data are available on the potential market and e-bike user behavior and interest.

Only a limited amount of research has explored the potential new market segments for e-bikes and the economic, operational, safety, and transportation issues surrounding e-bikes in the United States. This webinar will present findings from a research project …


Webinar: Transport Cost Index: A New Comprehensive Performance Measure For Transportation And Land Use, Liming Wang Oct 2015

Webinar: Transport Cost Index: A New Comprehensive Performance Measure For Transportation And Land Use, Liming Wang

TREC Webinar Series

Recent federal and state policies are placing increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making processes covering policy areas ranging from mobility, safety, economy and livability, to issues of equity and environment. While it is relatively easy to build consensus on mobility measures that center on the transportation system alone, it is much harder for performance measures to incorporate both transportation and land use, loosely defined as accessibility measures, even with continuous efforts to catalog and design such measures.

Two projects at PSU sponsored by Oregon DOT and National Institute of Transportation Communities (NITC) aim …


Webinar, Part I: Americans' Views Of Transportation And Livable Communities, Jennifer Dill, Hugh Morris Aug 2015

Webinar, Part I: Americans' Views Of Transportation And Livable Communities, Jennifer Dill, Hugh Morris

TREC Webinar Series

The National Association of Realtors® and Portland State University conducted a nationwide survey in the 50 largest metropolitan areas, asking Americans about where they live, where they want to live, and their travel habits.

This webinar will present the key findings from that survey, including people’s preferences to live in mixed-use, walkable communities and what may help them walk, bicycle, and take transit more. The large sample (3,000) allows us to look at demographic differences, including between the generations (Millennials, Baby Boomers, etc.).


Webinar: A Comprehensive Evaluation Of Protected Cycling Facilities: Lessons From Five Cities, Christopher Monsere Mar 2015

Webinar: A Comprehensive Evaluation Of Protected Cycling Facilities: Lessons From Five Cities, Christopher Monsere

TREC Webinar Series

As cities move to increase levels of bicycling for transportation, many practitioners and advocates have promoted the use of protected bike lanes (also known as “cycle tracks” or “protected bikeways”) as an important component in providing high-quality urban infrastructure for cyclists. These on-street lanes provide more space and physical separation between the bike lane and motor vehicle lane compared with traditional striped bike lanes. However, few U.S. cities have direct experiences with their design and operations, in part because of the limited design guidance provided in the past. There is limited research from North America on protected bike lanes, but …
