OVERVIEW

Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes.

Recently, new sources of bicycling activity data have emerged such as Strava, Streetlight, and GPS-enabled bike share systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has been questioned, and their suitability for producing bicycle volume estimates has yet to be rigorously explored. This project develops a method for evaluating and integrating emerging sources of bicycle activity data with conventional demand data and methods, and applies the results to several locations to predict network-wide bicycle volumes.

KEY LEARNING OUTCOMES

• Familiarity with a method for evaluating and integrating emerging sources of bicycle activity data with conventional methods;
• An understanding of the limitations and opportunities of new and emerging data sets;
• Results of a test application of a new method for integrating data from various sources.

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at Portland State University and the University of Texas at Arlington. The project is supported by a pooled fund grant. Matched by NITC, funding partners include Oregon Department of Transportation, Virginia DOT, Colorado DOT, Central Lane MPO, Portland Bureau of Transportation, District DOT, and Utah DOT.

OVERVIEW

With findings from a mixed methods research study, this interdisciplinary webinar will present results from a historical public document analysis, a GIS spatial analyses, client surveys and interviews, and interviews with professionals and service providers. In 2019, the delivery of homeless sheltering services in Salt Lake County transitioned from a centralized emergency shelter to a scattered site model with multiple resource center locations, operated by multiple service providers. To understand the degree to which “proximity” to public transportation and other needed services was achieved, this study examined:

1. how the decentralization of homeless services influenced transportation demand and mobility patterns for persons experiencing homelessness; and
2. how transportation and mobility changes affected access to services.

Findings reveal that while the region’s homelessness services system changed, the transportation network went unchanged, challenging the use of transportation, mobility, and access to services. Recommendations to mitigate transportation issues when homeless services are decentralized include significant consideration of how the transportation network system will evolve alongside the restructured service system. This could include development of no- or low-cost transportation on demand options, expanding bus routes, state-level funding for a shuttle system, and education for people experiencing homelessness on how to use public transit.

KEY LEARNING OUTCOMES

• The audience will learn about a case study of a homeless shelter that was replaced by multiple shelters and how this change affected the mobility of those receiving services.
• The audience will learn about how public transportation networks need to be in dynamic cooperation with other municipal and social services, with particular attention toward how those experiencing homelessness require access to public transportation services.
• The audience will learn about the need to offer transportation on demand to persons experiencing homelessness, provide education on transportation and system navigation, and increase transportation-related funding to ensure transportation costs are not a barrier to healthcare and social services.

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at the University of Utah. Read more about the project: Understanding the Mobility Impacts of Decentralizing Homeless Services in Salt Lake County, Utah.

THE TOPIC 

In 2022, cars are ubiquitous and completely embedded into America’s economy and social fabric. American cities don’t make car plans, but all transportation plans – whether they are for people who walk, bike, take transit, run freight or delivery businesses – are all written in response to cars. Transportation planning is all about cars; supporting cars or constraining cars. How did our cities evolve into places where cars dominate, and where can we go from here? To move to a new paradigm, cities need to acknowledge car dominance and focus on cars with the same rigor they do other modal plans – the history of cars in the city, the streets cars dominate, the actual vehicles, the drivers, and our future with cars. In the process of writing a Car Master Plan for Downtown Portland, Cathy Tuttle uncovered remarkable new information about curb space use, asphalt, and the four types of drivers.

KEY LEARNING OUTCOMES

• Cars are centered in all transportation planning. This needs to change.
• People drive for a variety of reasons. In order to change car use, we need to address the needs of Four Types of Drivers.
• We direct massive resources to enable comfortable car use. A Car Master Plan identifies and reorients these resource uses.

THE TOPIC 

Transit priority lanes restrict access to certain lanes, prioritizing transit movement, while sometimes allowing for other users or specific actions - for example shared bus and bike lanes, or shared bus and right-turn lanes. Red coloring is sometimes used to reinforce the transit priority with the goal of improving the reliability, safety and compliance with the lane restrictions. The City of Portland and TriMet have been working with partners to use these tools to improve mobility and transit access under the Enhanced Transit Corridors Plan and Rose Lanes Project. This presentation will report back on early lessons learned as part of the design, implementation and evaluation of these facilities, with presenters from the City of Portland, TriMet and Portland State University.

KEY LEARNING OUTCOMES

• Planning and design approaches to improve transit service through prioritizing transit movement.
• Interagency coordination on planning, implementing and evaluating transportation projects.
• Transit lane treatments to accommodate bus activity and other permitted movements (e.g. turning movements).
• Strategies to improve road user compliance and transit service.

THE TOPIC 

Cities across the U.S. are facing alarming increases in traffic fatalities, especially among the number of pedestrians who are struck and killed by drivers. Last year, 70 percent of all pedestrian fatalities in Portland were of people experiencing houselessness. As the Portland Bureau of Transportation (PBOT) is updating the city's Vision Zero Plan, a team of PSU urban and regional planning masters students have been investigating how to reduce the risk of being hit and killed specifically for unhoused people. During this presentation, the Street Perspective team will explain the situation, review their approach, and then share the recommendations they'll be providing to PBOT to reduce the risk of pedestrian fatalities among the city's vulnerable houseless communities.

This project was conducted by graduate students in the Master of Urban and Regional Planning (MURP) program at Portland State University. They work in teams of 4–6 members to complete applied planning projects, as part of a required course known as "the MURP workshop." This course is intended to give our students hands-on experience in conceiving, planning, and implementing a community-based planning project in close consultation with a committed client/partner. 

KEY LEARNING OUTCOMES

• The solution is more complex than simply sweeping camps near high-crash corridors and moving people experiencing houselessness to safer locations.
• Sweeping in and of itself only makes the problem worse, contributing to declining mental, physical, and emotional health for unhoused people.
• Access to basic needs and services is crucial to the well-being of houseless individuals, and creating safer access should be a priority.

SPEAKERS

Street Perspective is a team of six MURP students from a variety of backgrounds, interests, and experiences: Peter Domine, Nick Meusch, Asif Haque, Angie Martínez, Sean Doyle, and Meisha Whyte. We are all committed to making Portland and other cities safer, more equitable, and more accessible places for all residents.

OVERVIEW

Shared electric scooters (e-scooters) are fast becoming a mobility option in cities across the United States. This new micromobility mode has the potential to replace car usage for certain trips, which stands to have a positive impact on public health and sustainability goals. However, many aspects of this emerging mode are not well understood.This webinar explores the findings of three NITC studies examining transportation mode choices, safety, and public health outcomes of electric scooters.

KEY LEARNING OUTCOMES

By the end of this presentation, the participant will be able to:

• describe the ways in which electric scooters may provide new substitutive, complimentary or synergist transportation opportunities for different activities, compared with conventional modes (e.g., vehicles, transit, biking, walking).
• distinguish different types of crash and injury behaviors and risks for electric scooter users in the built environment.
• recognize relationships between mode choices around e-scooters may influence other health outcomes, including those related to changes in physical activities.

THE RESEARCH

The three studies were funded by the National Institute for Transportation and Communities (NITC):

• Evaluation of Portland Shared E-Scooter Pilot Program Goals and Outcomes: The primary objective of this research is to quantify the impacts of scooter operations on vehicle miles traveled (VMT). Led by John MacArthur, Portland State University.
• Scooting to a New Era in Active Transportation: Examining the Use and Safety of E-Scooters: This study examined the interplay between demographics, behaviors and trip purposes in order to better understand the potential impacts of e-scooters on land use, infrastructure and sustainability goals. Led by Kristi Currans, University of Arizona.
• E-Scooters and Public Health: Understanding the Implications of E-Scooters on Chronic Disease: This project investigates the impact of e-scooter use on chronic disease and public health, examining factors such as pollution exposure and physical activity. Led by Nicole Iroz-Elardo, University of Arizona.

OVERVIEW

Transportation systems play a critical role in maintaining supply chains for effective post-disaster recovery. Modeling the potential economic impact of transportation-related disruptions, therefore, is an important step to promoting pre-event communitywide recovery and resilience planning. But existing supply chain and economic impact models are cost prohibitive and overly sophisticated for use by public sector entities with limited resources. There is also limited understanding of how small and medium enterprises (SMEs) adjust to post-disaster transportation disruption and how this experience influences their future preparedness for similar events. Since SMEs make up a majority of businesses within the US, post-disaster transportation loss can significantly affect the local economy and the recovery trajectory for the entire community.

This project has two objectives:

1. To develop a collaborative university-community partnership framework for analyzing the economic impact due to transportation disruptions in earthquake country
2. To examine SME preparedness to such managing such disruptions.

In phase one, the project used the scenario of an M7.0 earthquake in Utah’s Wasatch Front and brought together a common set of public sector actors (namely, emergency management departments, metropolitan planning organizations, port authorities, and university research centers) and tools they already use (namely, HAZUS, travel demand modeling and REMI+) to help assess the potential impact of catastrophic earthquakes on the regional economy.

The second phase of the study surveyed 150 SMEs within the top 10 worst-affected industrial sectors identified in Phase 1 to understand how they are currently navigating supply disruptions due to COVID-19 and their future earthquake preparedness. In addition to generating deeper understanding of economic impacts of transportation disruption, the project also develops a collaborative framework that can easily be transferred to other communities that need similar supply chain and economic impact assessments for their resilience planning purposes.

KEY LEARNING OUTCOMES

• Understanding of how small and medium enterprises (SMEs) adjust to post-disaster transportation disruption;
• Introduction to a collaborative framework for supply chain and economic impact assessments;
• How to transfer this framework to other communities where it can be of use.

THE TOPIC 

This project investigated strategies towards development, marketing and implementation of employer programs for reducing single occupancy vehicles to mitigate traffic congestion. It was guided by the following research questions: which socio-economic factors influence carpooling; how do environmental factors influence carpooling; and what are effective traffic management strategies for enhancing carpooling. The presentation will also strive to introduce the US context for purposes of perspective.

KEY LEARNING OUTCOMES

• To understand the context of rideshare issues in developing countries (Kenya).
• To gain a comparative perspective between US and Kenyan context of rideshare practices.
• To appreciate challenges and opportunities of rideshare programs in general.

COVID-19 SAFETY PROTOCOLS

Effective March 19, 2022, Portland State University no longer requires that masks be worn in classrooms, offices, and most other public and private indoor spaces.
As PSU shifts into the next phase of the response to COVID-19, we understand that some in our community may feel more comfortable continuing to wear a mask. That is a personal decision that we wholeheartedly support. We ask that our community respect the choice of people who keep their masks on, but to refrain from asking others to wear a mask. Disposable masks will continue to be available at PSU building entrances.
