The E-Bike Potential: Estimating The Effect Of E-Bikes On Person Miles Travelled And Greenhouse Gas Emissions, Michael Mcqueen, John Macarthur, Christopher Cherry May 2019

The E-Bike Potential: Estimating The Effect Of E-Bikes On Person Miles Travelled And Greenhouse Gas Emissions, Michael Mcqueen, John Macarthur, Christopher Cherry

TREC Final Reports

Many cities have goals for reducing automotive VMT in order to reduce tailpipe emissions and to reduce congestion. Conventional cycling is a good solution, though its uptake has slowed in recent years in several cities, despite the implementation of greenways, bikeshare, and bike lines (Anderson and McLeod 2017). Electric bicycles (e-bikes) could be an effective new part of the solution to combat mode shift stagnation. The e-bike is a recently introduced mode of travel that is rapidly gaining in popularity throughout the United States.

The e-bike can offer a cheaper alternative to car travel (Popovich et al. 2014) and can …

How E-Bike Incentive Programs Are Used To Expand The Market, Michael Mcqueen, John Macarthur, Christopher Cherry May 2019

How E-Bike Incentive Programs Are Used To Expand The Market, Michael Mcqueen, John Macarthur, Christopher Cherry

TREC Final Reports

The electric bicycle (e-bike) is a low emission mode of transportation that offers communities benefits in the areas of health, planning, time, cost, street safety, congestion, air pollution, noise pollution, and energy security (Blondel, Mispelon, and Ferguson 2011). In a recent study conducted by Portland State University, e-bikes have been found to enable more people to ride a bicycle for longer distances despite physical limitations, difficult terrain, and the presence of cargo (MacArthur et al. 2018). However, overall e-bike adoption in the United States remains limited due in part to high purchase cost (Dill and Rose 2012; Popovich et al. …

Value Capture To Fund Public Transportation: The Impact Of Warm Springs Bart Station On The Value Of Neighboring Residential Properties In Fremont, Ca, Shishir Mathur

Mineta Transportation Institute

This study estimates households’ willingness to pay for single-family houses and condominiums/townhouses located within 2 miles of Warm Springs (WS) BART Station in Fremont, CA. The study finds that, compared to the houses sold in the referent category (2 to 5 miles away and sold during the pre-project-announcement period of 2000-2001), an average-priced single-family house within two miles of the WS BART Station was higher in price by 9% to 15%. The total property value increment for the single-family houses is large enough to fund the $802 million Warm Springs BART Extension Project cost five times over.

“Paying” The Way For A Better Bart Future: A Call For Better Enforcement Of Fare Evasion Policies And Strategic Planning At Bart, Ethan S. Tan

Creative Activity and Research Day - CARD

The Bay Area Rapid Transit (BART) system has undoubtedly shaped the way the San Francisco Bay Area operates today. BART has molded itself to becoming a popular form of transportation for citizens of the area. However, numerous problems have arisen in recent years in regard to the overall “healthiness” of the BART system with its ex-aging fleet of trains, undertrained staff, lack of BART Police presence, rampant illegal drug use, etc. which has made BART unpopular with riders. The root cause of these problems through, is the lost revenue through “stolen” rides. At any one of BART’s 48 stations in …


Addressing Changing Demographics In Environmental Justice Analysis, Aaron Golub Apr 2019

Addressing Changing Demographics In Environmental Justice Analysis, Aaron Golub

TREC Project Briefs

Since 1994, every Federal agency has a mandate to develop a strategy for identifying and addressing disproportionately high and adverse human health or environmental effects on low income populations and minority populations. In transportation planning this means including those communities’ voices in the planning process, and evaluating the social impacts early on.

A new report from the Federal Highway Administration (FHWA), prepared by Portland State University and ICF International, provides an in-depth analysis of national demographic trends and a synthesis of best long-range planning practices borne out of five case studies

Traffic Signal Consensus Control, Gerardo Lafferriere Apr 2019

Traffic Signal Consensus Control, Gerardo Lafferriere

TREC Final Reports

We introduce a model for traffic signal management based on network consensus control principles. The underlying principle in a consensus approach is that traffic signal cycles are adjusted in a distributed way so as to achieve desirable ratios of queue lengths throughout the street network. This approach tends to reduce traffic congestion due to queue saturation at any particular city block and it appears less susceptible to congestion due to unexpected traffic loads on the street grid. We developed simulation tools based on the MATLAB computing environment to analyze the use of the mathematical consensus approach to manage the signal …


Urban Goods Movement And Local Climate Action Plans: Assessing Strategies To Reduce Greenhouse Gas Emissions From Urban Freight Transportation, Andrew R. Goetz, Serena Alexander Apr 2019

Urban Goods Movement And Local Climate Action Plans: Assessing Strategies To Reduce Greenhouse Gas Emissions From Urban Freight Transportation, Andrew R. Goetz, Serena Alexander

Mineta Transportation Institute

This report examines how freight transport/goods movement has been addressed in U.S. city climate action planning. Transportation generally is a major contributor of greenhouse gas (GHG) emissions, and freight transport represents a growing component of transportation’s share. Almost all climate action plans (CAPs) address transportation generally, but we wished to focus on efforts to reduce GHG emissions from freight transport specifically. We analyzed 27 advanced local CAPs to determine the degree to which freight transport was targeted in goals and strategies to reduce GHG emissions. We found only six CAPs that included direct measures or programs to reduce freight emissions. …

Housing And Mobility Toolkit For San Mateo County, Serena Alexander, Joseph Kott, Bruce Appleyard, Mark Garrett, Shannon Mcdonald, Maaza Mekuria, Udeme J. Ndon, Anurag Pande, Eric Peterson

Mineta Transportation Institute

Since the end of the Great Recession, San Mateo County has attracted new workers at a record rate without building anywhere near enough housing. This jobs-housing imbalance drives the cost of housing up and forces many moderate and lower-income employees and their families out of the County. A lack of access to quality affordable housing in the County and the entire Bay Area along with limited transportation options means that an increased number of employees drive in and out of the County every workday. The resultant congestion, gridlock, and long commutes along with other negative environmental, social, and economic impacts …


Webinar: E-Bikes For Everyone: Electrifying Communities In New Ways, John Macarthur, Sergio Lopez Mar 2019

Webinar: E-Bikes For Everyone: Electrifying Communities In New Ways, John Macarthur, Sergio Lopez

TREC Webinar Series

Electric bicycle (e-bike) use is a rising phenomenon in North America. In 2018, John MacArthur of Portland State University conducted a national survey to understand issues facing e-bike owners. Reducing physical exertion, conquering challenging topography and replacing car trips are a few of the most important reasons for buying an e-bike. The electric assist of the e-bike helps to generate more trips, longer trips and different types of bicycle trips. Through analysis it also became evident that e-bikes are making it possible for more people to ride a bicycle, many of whom are incapable of riding a standard bicycle or …

PedPDX prioritizes sidewalk and crossing improvements and other investments, policies, strategies and tools to make walking safer and more comfortable across the city.

Come learn about the strategies PedPDX is using to address transportation equity in Portland, including establishing a data-based prioritization for citywide pedestrian investments, identifying roadway and behavioral characteristics most closely …


Public Transportation And New Mobility, Chris Pangilinan Mar 2019

Public Transportation And New Mobility, Chris Pangilinan

PSU Transportation Seminars

New mobility options such as bike share, scooters, and transportation network companies (e.g. Uber) are proliferating across the United States and beyond. Early research has shown that while the private automobile continues to be the main competition for transit, new mobility options may also be siphoning off some riders. In this seminar, we will explore what the role of public transportation should be in this era of rapidly expanding private transportation options. We will also examine how private transportation could be harnessed to help public transportation succeed and allow for cities to meet their mobility goals.


V2x: Bringing Bikes Into The Mix, Stephen Fickas Mar 2019

V2x: Bringing Bikes Into The Mix, Stephen Fickas

TREC Final Reports

This project demonstrates how an inexpensive system (hardware and software) can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system integrates three components: (1) a Bike Connect box that resides near the signal-controller and is connected to it, (2) an application that runs on a Bike Connect device (currently an iPhone) and requests a green light at the correct approach-distance, and (3) a cloud-based publish/subscribe (pub/sub) component that handles cellular-communication between phone app and box. One stumbling block for the project was a means to obtain reliable GPS data to …

Odot Highway Cost Allocation Study Review: Challenges In Including Regional Revenues, Northwest Economic Research Center, Thomas Potiowsky, Emma Willingham, Katelyn Kelley, Devin Bales

Northwest Economic Research Center Publications and Reports

This report, written for the Oregon Department of Transportation (ODOT) by Portland State University’s Northwest Economic Research Center, outlines the challenges that regional revenue collection poses for ODOT’s biennial Highway Cost Allocation Study (HCAS). The HCAS assesses the relative burdens of light and heavy vehicle classes on state infrastructure, in relation to the amount of revenue that said vehicle classes generate. In other words, it ensures that light vehicles and heavy vehicles are “paying their share” of state transportation expenditures.

Differences in vehicle traffic or differential impacts to vehicle classes are the root cause of most of the problems that …

From Knowledge To Practice: Rethinking Streets For People On Bikes, Marc Schlossberg, John Rowell, Roger Lindgren

TREC Project Briefs

For too long we’ve been building streets as though they have one function–to move cars quickly. The reality is that streets can to do more than just move cars. They can move people on foot, on bikes, on transit, without hurting vehicular throughput and safety. They can be more than a way to get somewhere else. Good streets are good places, too – public places where people meet, sit and socialize, conduct business, wander about, play, and more.

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 …
