Webinar: Engaging Youth To Choose Car-Free Mobility, Autumn Shafer

TREC Webinar Series

Today’s youth are tomorrow’s riders, bikers, walkers, voters, and transportation planners. As more transit agencies begin to offer free fare passes to public middle and high school students, it is important to have good communication strategy in place to encourage transit usage so they don't miss out on the potential to affect behavior change.

Thus, transit agencies need to develop age-appropriate messaging strategies and tactics that promote youth car-free mobility.

This webinar will present results from a NITC research project that sought to create and evaluate communication messaging that fosters more positive attitudes, intentions, and behaviors related to transit and …

Making The Seemingly Impossible Project Real Through Local Improvement Districts, Andrew H. Aebi

PSU Transportation Seminars

The planning process identifies community needs but often needs the creative use of financial leverage to make those projects a reality on the ground. Timing is important on Local Improvement District (LIDs), and the window of opportunity is often short.

For Portland's Bureau of Transportation, managing the public's desire for streets in good condition with room to walk and bike safely and accommodating freight movement and population growth can be a tall order. Add in the need to work with water, sewer and underground utilities, and things get complicated.

When needs exceed resources, smart strategies can help fill the gap. …

Do Transportation Network Companies Decrease Or Increase Congestion?, Gregory D. Erhardt, Sneha Roy, Drew Cooper, Bhargava Sana, Mei Chen, Joe Castiglione

Civil Engineering Faculty Publications

This research examines whether transportation network companies (TNCs), such as Uber and Lyft, live up to their stated vision of reducing congestion in major cities. Existing research has produced conflicting results and has been hampered by a lack of data. Using data scraped from the application programming interfaces of two TNCs, combined with observed travel time data, we find that contrary to their vision, TNCs are the biggest contributor to growing traffic congestion in San Francisco. Between 2010 and 2016, weekday vehicle hours of delay increased by 62% compared to 22% in a counterfactual 2016 scenario without TNCs. The findings …

That Bike Is Too Heavy: Merging Bicycling Physics, Human Physiology And Travel Behavior, Alexander Y. Bigazzi

PSU Transportation Seminars

Are the Biketown bikes too heavy? Does better gear motivate people to cycle more? How much faster will someone go on an e-bike?

Although urban cycling is widely known as physically active transportation, the actual physics of cycling have been given little attention in transportation engineering and planning. In contrast, the field of sports science has developed detailed data and models of road bicycle performance, but only for sport and racing cyclists.

What can we learn about utilitarian cycling by integrating knowledge of the physical attributes of bicycles and cyclists?

This seminar examines the ways in which bicycle physics, and …

Auto-Calibration Of Wim Using Traffic Stream Characteristics, Johnson Baker

Graduate Theses and Dissertations

This project evaluates the performance of Weigh-in-Motion (WIM) auto-calibration methods used by the Arkansas Department of Transportation (ARDOT). Typical auto-calibration algorithms compare the WIM measured weights of vehicles from the traffic stream to reference values, using five-axle tractor-trailer configured trucks for comparisons, e.g. Federal Highway Administration (FHWA) Class 9. Parameters of the existing algorithms including the Front Axle Weight (FAW) reference value, the sampling frequency required to update the calibration factor, and thresholds for Gross Vehicle Weight (GVW) bins were evaluated. The primary metric used to estimate algorithm performance was Mean Absolute Percent Error (MAPE) between the WIM and static …

How Will Autonomous Vehicles Change Local Government Budgeting And Finance? Case Studies Of On-Street Parking, Curb Management, And Solid Waste Collection, Benjamin Y. Clark

TREC Final Reports

This report is an examination of parking, curb zones, and government service changes in the context of AVs. Given that there are very few actual AVs on the road, the analysis in this report is an attempt to project what we might see, using the current phenomenon as starting points. The report uses a mix of econometric modeling, cost accounting, and case studies to illustrate these projections. The first section of this report looks at the effects of transportation network companies (TNCs)—Uber and Lyft in particular—on parking revenue in the city of Seattle. The results of the study indicate that …

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

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. …

How And Where Should I Ride This Thing? “Rules Of The Road” For Personal Transportation Devices, Kevin Fang, Asha Weinstein Agrawal, Ashley M. Hooper

Mineta Transportation Institute

In recent years, “Personal Transportation Devices” (PTDs) have exploded onto streets and sidewalks. These small devices transport individual persons at slow speeds and are either human-powered or motorized. Examples include electric (kick) scooters, skateboards, e-skateboards, roller blades, and Segways. One key to successfully integrating PTDs into community streets will be the implementation of consistent and suitable regulations over user behavior: “rules of the road” for PTD riders. To help local officials identify appropriate rules for rider behavior, this report documents and analyzes existing PTD regulations across 176 jurisdictions and then presents recommendations for a set of state-level “rules of the …

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.

Modeling Driver-Pedestrian-Infrastructure Interactions At Signalized Midblock Crosswalks, Boniphace Kutela

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cities and metropolitan areas are increasingly facilitating pedestrians’ movement by the provision of pedestrian walking facilities. As pedestrian traffic increases, the risk of crash involvement increases, especially at midblock locations, where pedestrians are exposed to unsafe interactions with vehicular traffic. To improve pedestrians’ safety at midblock locations, various countermeasures are provided, which include signalized crosswalks. Several studies have analyzed driver-pedestrian interactions, as well as pedestrian-infrastructure interactions at signalized midblock crosswalks. However, more in-depth studies are necessary, due to shortfalls of study assumptions, which have led to the application of improper statistical models, as seen in the literature. Improved models are …

“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 …

Low-Income Access To Employer-Based Transit Benefits: Evidence From 10 Large Metropolitan Regions, Andrea Hamre

Journal of Transportation Demand Management Research

While national aggregate statistics suggest employer-based transit subsidies may be inaccessible to the majority of the working poor, this is the first study to investigate the subject with disaggregate data while controlling for additional factors. This study uses household travel surveys for 10 of the largest Metropolitan Planning Organizations, grouped into seven cases. In each case, the share of workers offered an employer-based transit subsidy is lowest for workers in the lowest income quintile. Binary logistic regression results for the odds of being offered an employer-based transit subsidy are presented for two cases, Washington, DC, and Denver, CO, and the …

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
