Improving Trip Generation Methods For Livable Communities, Kelly J. Clifton, Nico Larco, Kristina Marie Currans, Jael Wettach-Glosser

TREC Final Reports

Recent efforts to improve trip generation data available for transportation impact analysis of new development include the collection of multimodal trip generation data, development of models that account for the built environment, and new recommendations for practice. Building on a long line of research on transportation and built environment, many studies have identified important features of the surrounding built environment that most impact trip rates and mode shares, building on a long line of research on transportation and the built environment. Despite these improvements in data and methods, less attention is placed on identifying the conditions of the site itself …

Estimating Reliability Indices And Confidence Intervals For Transit And Traffic At The Corridor Level, Travis B. Glick

PSU Transportation Seminars

As congestion worsens, the importance of rigorous methodologies to estimate travel-time reliability increases. Exploiting fine-granularity transit GPS data, this research proposes a novel method to estimate travel-time percentiles and confidence intervals. Novel transit reliability measures based on travel-time percentiles are proposed to identify and rank low-performance hotspots; the proposed reliability measures can be utilized to distinguish peak-hour low performance from whole-day low performance. As a case study, the methodology is applied to a bus transit corridor in Portland, Oregon. Time-space speed profiles, heatmaps, and visualizations are employed to highlight sections and intersections with high travel-time variability and transit low performance. …

Current Efforts To Make Bike Share More Equitable: A Survey Of System Owners And Operators, Steven Howland

PSU Transportation Seminars

The number of public bike share systems has been increasing rapidly across the United States over the past five to ten years. To date most academic research around bike share in the U.S. has focused on the logistics of planning and operationalizing successful systems. Investigations of system users and impacts on the local community are less common, and studies focused on efforts to engage underserved communities in bike share are rarer still. This paper utilizes a survey of representatives from 55 U.S. bike share systems to better understand and document current approaches toward serving low income and minority populations. The …

Webinar: Improving Walkability At Signalized Intersections With Signal Control Strategies, Edward J. Smaglik, Sirisha Murthy Kothuri

TREC Webinar Series

The goal of signal timing at an intersection should be to maximize efficiency for all users. In many jurisdictions, however, traffic signals are timed mostly with the goal of reducing vehicular delay.

Other road users, such as pedestrians, deserve similar focus. In legacy transportation systems, pedestrians experience delays much in excess of those that would be deemed acceptable for a motor vehicle at the same location.

Excessive delay can lead to pedestrian frustration, non-compliance and ultimately decreased safety.

In the North American context, implementation of strategies to address pedestrian service varies greatly across jurisdictions, and there has been limited research …

Measuring Stress Levels For Real-World On-Road Cyclists: Do Bicycle Facilities, Intersections And Traffic Levels Affect Cyclists' Stress?, Álvaro Caviedes

PSU Transportation Seminars

This research effort presents a novel approach to measure cyclists’ stress: real-world, on-road measurements of physiological stress as cyclists travel across different types of bicycle facilities in various traffic volumes. This study addresses the question of how the characteristics of a bicycle trip affect stress levels using physiological data, specifically GSR. As detailed in the next section, GSR-based studies have been successfully employed for many years in the psychological field to recognize and associate emotions and behaviors to physiological responses. The three research questions examined in this study are: i) Does peak traffic impact cyclists’ stress levels? ii) Do intersections …

A Pathway Linking Smart Growth Neighborhoods To Home-Based Pedestrian Travel, Steven R. Gehrke, Kelly J. Clifton

PSU Transportation Seminars

Land development patterns, urban design, and transportation system features are inextricably linked to pedestrian travel. Accordingly, planners and decision-makers have turned to integrated transportation-land use policies and investments to address the pressing need for improvements in physical activity levels via the creation of walkable communities. However, policy questions regarding the identification of smart growth indicators and their connection to walking remain unanswered, because most studies of the built environment determinants of pedestrian travel: (a) represent the built environment with isolated metrics instead of as a multidimensional construct and (b) model this transportation-land use relationship outside of a multidirectional analytic framework. …

Avoiding Bus Bunching: From Theory To Practice, Ricardo Giesen

PSU Transportation Seminars

The problem of bus bunching in a high frequency service has been largely studied in the literature.

This phenomenon is produced by three main factors

(i) the variability in travel time between stops; (ii) variations in passenger demand; and (iii) drivers’ heterogeneity.

In order to tackle this phenomenon a wide range of control strategies have been proposed, however, none of them had been successfully implemented on a large transit network with high frequency services.

In this talk, we present a control scheme based on a rolling horizon optimization problem that has been successfully implemented for real-time control of two high …

Improving Walkability Through Control Strategies At Signalized Intersections, Sirisha Murthy Kothuri, Andrew Kading, Edward J. Smaglik, Christopher Sobie

TREC Final Reports

As cities and communities nationwide seek to develop Complete Streets that foster livability and accommodate all modes, signal timing control strategies that include pedestrians in the operational decision process are gaining importance. This research tested several efficiency-focused pedestrian treatments – coordination, actuated-coordination, free operation, short cycle lengths – and safety-focused treatment including leading pedestrian intervals and Barnes Dance. Using a software-in-the-loop simulation, the operational impacts of these treatments on all users (vehicles, heavy vehicles, bicyclists and pedestrians) at an intersection were evaluated. Results showed that among the efficiency-based treatments, free operation was most beneficial for reducing minor-street pedestrian delays. Both …

Cross-Laminated Timber: An Innovative Building Material Takes Hold In Oregon, Andrew Crampton

Metroscape

In a rapidly urbanizing world fueled by the enormous demand to house and shelter billions of people in the upcoming decades, building materials must be utilized that have a lighter climate impact than today’s commonly used energy-intensive building materials.

Is there an alternative to the energy-intensive concrete jungle that is both sustainable and financially viable? How can our built environment enhance, rather than destroy, the natural environment? Part of the solution lies in a recent innovation that uses one of the world’s oldest building materials, wood, with a modern twist: cross-laminated timber, often abbreviated as CLT. These wood-based structures can …

Differences Of Cycling Experiences And Perceptions Between E-Bike And Bicycle Users In The United States, Ziwen Ling, Christopher R. Cherry, John Macarthur, Jonathan X. Weinert

Civil and Environmental Engineering Faculty Publications and Presentations

E-bikes are bicycles that provide pedal-assistance to aid people in cycling. Because of the potential of promoting sustainable transportation, more attention has been focused on the e-bike market. This paper investigates the differences of the cycling experience and perceptions between e-bike and conventional bicycle users, using samples drawn from independent bicycle dealer customers. A total of 806 respondents in the United States took the on-line survey, including 363 e-bike-owning respondents. The results show that e-bikes play a more important role in utilitarian travel, such as commuting and running errands, compared to a conventional bicycle. Conventional bicycle-owning respondents use their bicycles …

Impact Of Last Mile Parking Availability On Commercial Vehicle Costs And Operations, Miguel Figliozzi, Chawalit Tipagornwong

Civil and Environmental Engineering Faculty Publications and Presentations

This research analyses how parking availability levels affect commercial vehicle parking costs and operations in congested urban areas. Unlike passenger vehicles, parking availability has an impact on route characteristics and commercial vehicle fleet sizes. Hence, commercial vehicles parking costs cannot be captured solely by estimating delays and/or the cost of parking fines. This research combines logistics, queuing, and optimization models to study the impact of last mile parking availability on commercial vehicle costs and operations. Scenarios are built to study the impact of parking availability on typical less-than-truckload (LTL) and courier service costs. Results indicate that parking availability levels do …

From Climbing Walls To A Culture Of Caring, Kirk Kelly, Brenna Miaira Kutch

Office of Information Technology Publications and Presentations

Ultimately, creating a culture of caring will make the difference between paying employees to work for the organization and having them get up in the morning wanting to work for the organization. Staff will be more engaged, more committed, and more productive, will encourage others, and will live longer lives. Caring can't be faked. While this article has mentioned many ways to focus on a culture of caring, caring is not a list of boxes to check off. It is never "finished." Training people to genuinely care is difficult to do, so organizational leaders must keep this attribute in mind, …

However, these fields of research are only recently beginning to converge, and we see great potential for further engagement. Here, we present an approach and conceptual tools for how the sense of place perspective can contribute to social-ecological systems research. A brief review focuses on two areas where relation to …

The Fountain District: Framework Plan, Kara Boden, Alyssa Brook, Jennifer Davidson, Michael Kimble, Julia Lui, Raina Smith, Steven Rosen, Laura Voss, Victoria Weakley

Urban Design Workshop

The 'South Auditorium' neighborhood established itself in the days when loggers and other workers filled the district’s hotels due to its proximity to the river. In the wake of the Great Depression and as the logging trade declined, the area began to fall into disrepair and development shifted away from the Willamette River. By the 1950s, many of its 2,000+ inhabitants were low-income or elderly and living in small, poorly maintained apartments, shuffling from one to the next as they were forced out of their prior home. The neighborhood was also extremely diverse, housing numerous immigrant families, particularly Italian, Jewish, …

Using transportation data and examples, it also aims to help students tackle the challenge of “drinking from a hose” when dealing with the overwhelming amount of data that is increasingly common in transportation research and practice.

Although computing is now an integral part of every aspect of science and engineering, transportation research included, most students of science, engineering, and planning are never taught how to build, use, validate, and share software …

The Compassion Of “Compassionate Migration”, John Shuford

Conflict Resolution Faculty Publications and Presentations

“Compassionate migration” carries social significance and implies moral criteria. This practical notion should provide means to review, envision, and develop laws, policies, and practices for how we engage noncitizens and build political community within wider human relations. Yet “compassion” is an elastic concept; competing discourses and practices reveal conflicting meanings, assumptions, and orientations. “Compassionate migration” needs criteria upon which its “compassion” is evaluated, including how this notion evolves and what practical results it inspires—such as social cohesion, immigrant integration, strengthened community, and societal transformation. Bookending the chapter’s conceptually driven discussion are two recent, and opposite, case studies in the American …
