Evaluation Of Bicyclists Exposure To Traffic-Related Air Pollution Along Distinct Facility Types, James F. Pankow, Miguel A. Figliozzi, Alexander Y. Bigazzi

Civil and Environmental Engineering Faculty Publications and Presentations

While bicyclists and other active travelers obtain health benefits from increased physical activity, they also risk an uptake of traffic-related air pollution. But pollution exposure for urban bicyclists is not well understood due to a lack of direct measurements and insufficient analysis of the determinants of exposure. This knowledge gap impedes pollution-conscious transportation planning, design, and health impact assessment. The research presented in this report generates new connections between transportation system characteristics and pollution exposure for bicyclists. The primary research questions are: 1) How does urban bicyclists’ exposure to air pollution vary with roadway and travel characteristics? and 2) To …

Associations Between Travel Behavior And The Academic Performance Of University Students, Qianying Wu

All Theses

Purpose: Different travel behavior, particularly the choice of commuting modes, will have different impacts on students. On one hand, it has been suggested that active commuting (walking, cycling, and taking transit) will add routine daily exercise. Moreover, health benefits (improved cognitive function and reduced anxiety) from physical activity might increase students' academic performance. Nevertheless, too much physical activity may reduce the time for students to study. Travel time may shorten study time, and study time has been identified as positively contributing to academic performance. Considering that there is limited research examining travel behavior and academic achievement of university students, this …

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the past, the studies in the U.S. on high speed rail have been on economic impact. Recently, there are a few studies on the multimodal connectivity at high speed rail stations. High speed rail stations are viewed as hubs that are connected by different modes of public transportation by which passengers are transported to their destinations. How and in which way these different modes are connected to high speed rail stations influence the ridership of high speed rail stations. As the development of high speed rail system in the U.S. has come to the stage for actual design and …

Modeling And Analysis Of Pedestrian Flows, Romesh Khaddar

UNLV Theses, Dissertations, Professional Papers, and Capstones

According to the Traveler Opinion and Perception Survey of 2005, about 107.4 million Americans regularly use walking as a mode of transport during their commute, which amounts for 51% of the total American population. In 2009, 4092 pedestrian fatalities were reported nationwide, out of 59,000 pedestrian crashes. This amounts for 12% of the fatalities in the total traffic accidents recorded, and shows an over-representation of pedestrians incidents. Thus, it is imperative to understand the causes behind such statistics, and conduct a comprehensive research on pedestrian walking behavior and their interaction with surroundings.

A lot of researches on pedestrian flows have …

Evaluating The Level-Of-Service Of Protected Bike Lanes, Nick Foster

PSU Transportation Seminars

Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods …

Can Protected Bike Lanes Help Close The Gender Gap In Cycling? Lessons From Five Cities, Jennifer Dill, Tara Goddard, Christopher Monsere, Nathan Mcneil

Urban Studies and Planning Faculty Publications and Presentations

Even in areas with increased levels of bicycling, there remains a significant “gender gap” in bicycling in the United States, in contrast to many other countries with high rates of bicycling. The primary objective of this paper was to explore whether protected bike lanes could help reduce the gender gap. To do so, the authors used survey data from a comprehensive evaluation of protected bike lanes in five large U.S. cities (Austin, TX, Chicago, IL, Portland, OR, San Francisco, CA, and Washington, DC) that included survey responses of 1,111 intercepted bicyclists and 2,283 residents. Both men and women overwhelmingly felt …

Historical Traffic-Tolerant Paths In Road Networks, Pui Hang Li, Man Lung Yiu, Kyriakos Mouratidis

Research Collection School Of Computing and Information Systems

Historical traffic information is valuable for transportation analysis and planning, as well as for route search services. In view of these applications, we propose the k traffic-tolerant paths problem (TTP) on road networks, which takes a source-destination pair and historical traffic information as input, and returns k paths that minimize the aggregate (historical) travel time. Unlike the shortest path problem, the TTP problem has a combinatorial search space that renders the optimal solution expensive to compute. We propose an exact algorithm and a heuristic algorithm for this problem. Experiments on real traffic data demonstrate the effectiveness of TTP paths and …

An Approach For Actions To Prevent Suicides On Commuter And Metro Rail Systems In The United States, Mti Report 12-33, Jan L. Botha, Marissa K. Neighbour, Satnam Kaur

Mineta Transportation Institute

The primary goals of this report are to discuss measures to prevent suicides on commuter and metro rail systems, and to outline an approach for suicide prevention on rail systems. Based on existing literature and analysis of data obtained from the Metrolink system in Southern California, it was found that most suicides occur near station platforms and near access points to the track. Suicides occurred most frequently when relatively more trains were in operation and in areas of high population density. There do not appear to be suicide “hot spots” (e.g., linked to mental hospitals in the proximity, etc.), based …

Trick Or Treat(Ment)? : Impact Of Route-Level Features On Walk And Bike Decisions, Joseph Broach

PSU Transportation Seminars

Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip?

Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike …

Accessibility's Influence On Population Location Near Light Rail In The Denver Region, Christophe Michael Zuppa

USF Tampa Graduate Theses and Dissertations

Accessibility is the most important concept in transportation planning because it describes the ease of travel to opportunities vital for everyday needs. Theoretically, people locate closer to transit corridors if accessibility improves. One desired benefit from light rail is denser land use patterns in the form of Transit Oriented Development (TOD) that captures population growth. In October 1994, the City of Denver, CO, joined the list of American cities that have implemented light rail within the last 33 years. Since then, five corridors have opened there, and planners are retooling their zoning codes to allow TOD near light rail. The …

Examining The Role Of Internal Planning Decisions In Improving Transit Performance And Economic Outcomes, Michal Jaroszynski

PSU Transportation Seminars

Scholars and practitioners continuously seek best practices to increase transit ridership, efficiency, and modal share. The ongoing suburbanization and decentralization of U.S. metropolitan regions brings new challenges for accomplishing these goals. Investigating possible strategies for improving transit outcomes in the existing socioeconomic setting, scholars from the Florida State University have pointed to the role of internal performance factors. In a series of research studies, they have found that improving transit service characteristics, such as frequency, connectivity, regional coverage, intermodal integration, as well as decentralization of network structures, could result in increased transit ridership and productivity. These positive effects could be …

Using "Big Data" For Transportation Analysis: A Case Study Of The La Metro Expo Line, Mohja L. Rhoads

PSU Transportation Seminars

Access to a comprehensive historical archive of real-time, multi-modal multi-agency transportation system data has provided a unique opportunity to demonstrate how “big data” can be used for policy analysis, and to offer new insights for planning scholarship and practice. We illustrate with a case study of a new rail transit line. We use transit, freeway, and arterial data of high spatial and temporal resolution to examine transportation system performance impacts of the Exposition (Expo) light rail line (Phase 1) in Los Angeles. Using a quasi-experimental research design, we explore whether the Expo Line has had a significant impact on transit …

Go Before You Go: How Public Toilets Impact Public Transit Usage, Kate M. Washington

PSU McNair Scholars Online Journal

The emphasis on sustainable solutions in Portland, Oregon includes developing multi-modal transportation methods. Using public transit means giving up a certain amount of control over one’s schedule and taking on a great deal of uncertainty when it comes to personal hygiene. Buses, the MAX, and the Streetcar – the cornerstones of public transit in Portland – are not equipped with toilets and rarely are their stations, while most shops and restaurants reserve toilets for patrons only. As a result, many people may bypass public transit in favor of cars, which afford travelers greater autonomy and flexibility. Theories of New Urbanism …

Heavy Vehicle Rollover Propensity At Roundabouts On Highspeed Roads, Thomas M. Hall

Open Access Theses

There is a recent trend of building roundabouts on high-speed roads, often with significant heavy vehicle traffic. With the increased presence of trucks on roundabouts, the issue of rollover has become a concern. Geometric features that allow excessive speed on the approach and entry have been connected to rollover, as well as sudden changes in crossfall and radius. However, the effect on the rollover threshold of changing the roundabout's circulatory superelevation is not fully understood. The impact of aggressive driving behaviors, as displayed by high driver speed far from the roundabout, as well as errors that are manifested by the …

Capacity-Related Driver Behavior On Modern Roundabouts Built On High-Speed Roads, Shaikh Ahmad

Open Access Theses

The objective of this thesis was to investigate the factors that affect capacity-related driver behavior on modern roundabouts built on high-speed roads. The capacity of roundabouts is strongly affected by the behavior of drivers as represented by critical headway (critical gap) and follow-up headway (follow-up time). The effects of heavy vehicles (single-unit truck, bus, and semi-trailer) and area type (rural or urban) on roundabout capacity were investigated by comparing the critical headways for roundabouts located on high-speed and low-speed roads. The effects of nighttime conditions (in the presence of street lighting) were also considered. Data were collected using the Purdue …
