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 …

Transportation Network Companies: Influencers Of Transit Ridership Trends, Richard A. Mucci

Theses and Dissertations--Civil Engineering

The major transit systems operating in San Francisco are San Francisco Municipal (MUNI), Bay Area Rapid Transit (BART), and Caltrain. The system of interest for this paper is MUNI, in particular the bus and light rail systems. During the past decade transit ridership in the area has experienced diverging growth, with bus ridership declining while rail ridership is growing significantly (Erhardt et al. 2017). Our data show that between 2009 and 2016, MUNI rail ridership increases from 146,000 to 171,400, while MUNI bus ridership decreases from 520,000 to 450,000. Direct ridership models (DRMs) are used to determine what factors are …

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 …

Impact Of Reclaimed Asphalt Pavement And Recycled Asphalt Shingles On Laboratory And Field Performance Of Texas Asphalt Concrete Pavements, Berenice Salaices Gomez

Open Access Theses & Dissertations

The use of recycled materials in Asphalt Concrete (AC) mixes is highly promoted in the transportation industry. Recycled materials minimize the use of virgin materials, reduce the consumption of resources, and cut costs for new construction or rehabilitation projects. The incorporation of Reclaimed Asphalt Pavement (RAP) and Recycled Asphalt Shingles (RAS) in the AC mixture is promoted as long as equal or improved performance is achieved. The Texas Department of Transportation (TxDOT) is currently placing asphaltic concrete (AC) mixes that are lasting less than their expected performance life when recycled materials are used.

The objective of this Thesis is to …

Analysis Of Infectious Diseases Screening Systems For Transatlantic Air Passengers, Lukas Gold
