Transportation Impacts Of Affordable Housing: Informing Development Review With Travel Behavior Analysis, Amanda Howell

PSU Transportation Seminars

Planning for affordable housing is challenged by development policies that often do not differentiate between the travel patterns of residents of market-rate housing and those living in affordable units. The development review process generally requires an evaluation of the anticipated additional transportation demand that new development places on the system and an assessment of fees or improvements to mitigate these impacts.

However, industry standard guidelines for assessment of travel demand outlined within the Institute of Transportation Engineers (ITE) Trip Generation Handbook have been focused solely on vehicle trip rates for these traffic impact analyses. Given the public goals of providing …

Project Phenom: A Smart Bike Project, Stephen Fickas

TREC Final Reports

This project introduces students to hands-on, experience-building, smart-transportation hardware and software. After completing the project, students will gain practical experience with integrating a set of inexpensive, commercial computer components to deliver a ready-to-install system that can extend the transportation grid of a city. They will also learn how to program the system to give bike riders and pedestrians in their community new power. Specifically, the system they build can give bicyclists and pedestrians a virtual push-button, allowing them to place a call for a green light prior to reaching an intersection, thus giving them the actual green light when they …

Reliability Testing Of The Star Rating For Schools (Sr4s) Mobile Application: Results From A Pilot Study, Ashley Hunt, Morag Mackay, Amira Roess

GW Research Days 2016 - 2020

Globally, approximately 3500 individuals are killed due to a road traffic injury each day, equating to nearly 1.3 million deaths each year and more than a million children are either killed by, or sustain serious injury, from road traffic incidents. School zones are locations where there may be high concentrations of children at certain hours of the day, thereby increasing their exposure to road and pedestrian injuries. The International Road Assessment Programme (iRAP), an NGO established in 2006, developed the Star Ratings measurement system, which is used globally to provide simple, comparable and objective measurements of the built-in safety of …

Improving Adolescents’ Driving Behaviors Through A Personal Narrative-Based Psychosocial Intervention In Serbia, Hagere Yilma, Rajiv Rimal, Nargis Ryskulova

GW Research Days 2016 - 2020

Objectives: Road traffic crashes continue to be the leading cause of death among adolescents. While males are more vulnerable to crashes than females, driver education interventions are less likely to succeed among males than females. Some studies suggest that stronger optimistic bias and overconfidence bias in males may be the reason for this.

Methods: In a quasi-experiment conducted in Serbia, forty schools were stratified by size and randomly assigned to watch a road traffic safety presentation utilizing personal narratives or to a control arm. Surveys were administered before the intervention (N=1,449) and again six months later (N=1,072). Data was …

Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri, Andrew Kading, Andrew Schrope, Kelly White, Edward Smaglik, Chris Aguilar, William Gil

TREC Final Reports

Over the last decade there has been increased interest in promoting active and sustainable transportation modes such as bicycling and walking especially in urban areas, as a means to alleviate congestion, lower emission levels and improve personal health. In urban areas, intersections are locations where a variety of modes converge, thus increasing the propensity for conflicts. Many bicycle-vehicle crashes occur at intersections. A common crash type involving bicycles at intersections is the “right-hook” where a right-turning vehicle collides with a through bicyclist. Intersections are also the source of increased stress for many bicyclists where the interactions with cars are more …

The Contribution Of Transportation And Land Use To Citizen Perceptions Of Livability In Oregon Mpos, Rebecca Lewis, Robert Parker

TREC Final Reports

What is livability? How does the built environment influence resident perceptions of livability? Although livability is a broadly used term and a key goal in land use and transportation plans at the state level, it is unclear whether residents think their neighborhoods are livable and what contributes to their perception of livability. The purpose of this project was to understand how Oregonians, in neighborhoods of varying densities and within Metropolitan Planning Organizations (MPOs), perceive livability at the nexus of transportation and land use. We sought to understand how residents define and perceive livability in three different MPOs in the state: …

Overcoming Barriers For The Wide-Scale Adoption Of Standardized Real-Time Transit Information, Sean J. Barbeau

TREC Final Reports

In the last few years, a real-time counterpart to GTFS, GTFS-realtime [10], has begun to emerge, with agencies sharing their real-time data in this format. Previously, real-time transit information had only been shared in proprietary formats specific to each vendor or agency. GTFS-realtime offers the opportunity for application developers to create a mobile app that can function across a large number of cities and agencies, and for practitioners and researchers to be able to easily study and compare actual system performance across different transit systems using the same tools, without the overhead of manually transforming data into a consistent format. …

Electric bicycle (e-bike) use is a rising phenomenon in North America, as a growing number of manufacturers produce a variety of bicycles which can accommodate the needs of diverse populations. With the growth of the e-bike industry, e-bike users are an increasingly integral part of both the transportation network and recreational trail system. However, little research has been conducted on e-bikes within North America, especially on the individuals who have purchased e-bikes.

Do Americans’ Opinions About Federal Transportation Tax Options Depend On Survey Mode? A Comparison Of Results From Telephone And Online Surveys, Hilary Nixon, Asha Weinstein Agrawal

Mineta Transportation Institute

This research project compared the results from a public opinion survey about transportation taxes that was administered using two different survey modes, a national, random-digit-dial (RDD) telephone survey and an online survey with respondents recruited from a panel. There is considerable interest among survey researchers in using online survey panels as a replacement for RDD surveys. RDD surveys are becoming much more expensive to conduct, and researchers also worry that the quality of the results may be dropping because of rising refusal rates for phone surveys. However, a key question for researchers is to understand how a study’s results may …

Insights On Walkability And Walking In Lisbon With The Iaape Method, Filipe Moura

PSU Transportation Seminars

Walkability and walking are being intensively researched today and the literature provides a wealth of references and examples on how to measure walkability of the built environment. IAAPE is one method that was developed at the Instituto Superior Técnico (Lisbon) to measure walkability at the micro-scale, bringing solutions that were disregarded in two aspects: it is a participatory process; and it provides different evaluations for different population segments (adults, children, seniors, impaired) or for different trip motivations.

Transit Demand Analysis And User Classification Using Automatic Fare Collection (Afc) Data, Alireza Khani

PSU Transportation Seminars

Development of origin-destination demand matrices is crucial for transit planning. The development process is facilitated by transit automated data, making it possible to mine boarding and alighting patterns on an individual basis. This research proposes a novel stochastic trip chaining method which uses Automatic Fare Collection (AFC) and General Transit Feed Specifications (GTFS) data to infer an origin-destination (O-D) matrix.

Citizen Advocacy For Safe Streets In Bremen, Germany, Anne Kirkham

PSU Transportation Seminars

Although Germany may be known internationally for its environmentalism, over the past 20 years German cities have chronically underinvested in transportation networks, both for public transport as well as non-motorized options. The lag in the development and expansion of sustainable options combined with the rapid growth in private automobile ownership (itself the result of automobile-industry-friendly policymaking) means that cities like Bremen have been left behind in terms of transportation planning. As in America, SUV sales continue to increase despite considerably narrower streets, particularly in cities.

Nowhere is this more visible than in Bremen’s Neustadt, a dense neighbourhood with the most …

Development Of Rdsetgo: A Rapidly Deployable Structural Evaluation Toolkit For Global Observation, Charles Riley

TREC Final Reports

The most expensive and critical links in the nation’s transportation network are its bridges. Historical and contemporary bridge failures have highlighted our reliance on these structures. While the nation’s bridge management system is robust and well administered, the tools needed to evaluate individual bridges to determine their condition, whether for asset management or in response to a significant loading event such as the imminent Cascadia Subduction Zone earthquake in the Pacific Northwest, are currently highly specialized. The goal of this study was to develop a cost-effective, accurate, and easily deployed evaluation tool using widely available mobile technology, specifically iPods, to …

A Portable Toolkit For Testing Bridge Structural Integrity, Charles Riley

TREC Project Briefs

The goal of this study was to develop a cost-effective, accurate, and easily deployed evaluation tool using widely available mobile technology (specifically iPods) to measure the dynamic structural response of a bridge subjected to harmonic forcing. Researchers leveraged principles of structural mechanics, dynamics, and vibrations, as well as a significant body of literature, to conceive a system that could complement existing visual inspection methods to support bridge condition evaluation and rating.
