Determinants Of Mobility Resource Ownership In Switzerland: Changes Between 2000 And 2010, Nicole Andréa Mathys, Matthias Kowald, Barbara Kieser, Andreas Justen 2016 Federal office for Spatial Development, University of Neuchâtel

Determinants Of Mobility Resource Ownership In Switzerland: Changes Between 2000 And 2010, Nicole Andréa Mathys, Matthias Kowald, Barbara Kieser, Andreas Justen

Nicole Andréa Mathys

The future development in mobility resource ownership is of great interest as the individual mobility behavior has critical impacts on transport infrastructure, land use, energy consumption, and environmental issues, such as greenhouse gas emissions and local air pollutants. Analysis and forecasts of mobility resource ownership as needed for example in transport modelling or forecast studies, however, usually employ data of the latest national travel surveys available. Therefore, changes in mobility resource ownership over time are often ignored. Estimating logit-based decision models on the large scale Swiss national travel survey data for 2000 and 2010, the study identifies determinants of mobility ...


Exploring Passenger Assessments Of Bus Service Quality Using Bayesian Networks, Jingxian Wu, Min Yang, Soora Rasouli, Chengcheng Xu 2016 Southeast University, China

Exploring Passenger Assessments Of Bus Service Quality Using Bayesian Networks, Jingxian Wu, Min Yang, Soora Rasouli, Chengcheng Xu

Journal of Public Transportation

Studies on public transit have emphasized the role of passenger satisfaction with service quality in travel choice decisions and indicated that satisfaction depends on various service attributes. Few studies have, however, systematically examined the underlying relationships among service attributes to assess their influence on passenger overall satisfaction. Therefore, to contribute to this rapidly-emerging literature, this paper applies Bayesian networks to quantify the influence of each service aspect on passenger overall satisfaction with regular bus service quality. This analysis involved 609 passengers who participated in a 2013 regular bus service survey in Nanjing, China. The derived Bayesian network shows the relationships ...

Trends In Mobile Transit Information Utilization: An Exploratory Analysis Of Transit App In New York City, Niloofar Ghahramani, Candace Brakewood

Journal of Public Transportation

Smartphone applications that provide transit information are now very popular. However, there is limited research that examines when and where passengers use mobile transit information. The objective of this research was to perform an exploratory analysis of the use of a smartphone application known as Transit App, which provides real-time transit information and trip planning (schedule) functionality. Backend data from Transit App were examined by time of day and day of week in the New York City metropolitan area. The results show that the pattern of both the trip planning feature and overall real-time information usage follow the typical pattern ...


Bus Transit Operational Efficiency Resulting From Passenger Boardings At Park-And-Ride Facilities, John S. Niles, J. M. Pogodzinski 2016 Center for Advanced Transportation and Energy Solutions

Bus Transit Operational Efficiency Resulting From Passenger Boardings At Park-And-Ride Facilities, John S. Niles, J. M. Pogodzinski

Mineta Transportation Institute Publications

In order to save time and money by not driving to an ultimate destination, some urban commuters drive themselves a few miles to specially designated parking lots built for transit customers and located where trains or buses stop. The focus of this paper is the effect Park-and-Ride (P&R) lots have on the efficiency of bus transit as measured in five bus transit systems in the western U.S. This study describes a series of probes with models and data to find objective P&R influence measures that, when combined with other readily-available data, permit a quantitative assessment of the ...


Improving Carbon Efficiency Through Container Size Optimization And Shipment Consolidation, Nang Laik MA, Kar Way TAN, Edwin Lik Ming CHONG 2016 Singapore Management University

Improving Carbon Efficiency Through Container Size Optimization And Shipment Consolidation, Nang Laik Ma, Kar Way Tan, Edwin Lik Ming Chong

Research Collection School Of Information Systems

Purpose: Many manufacturing companies that ship goods through full container loads found themselves under-utilizing the containers and resulting in higher carbon footprint per volume shipment. One of the reasons is the choice of non-ideal container sizes for their shipments. Consolidation fills up the containers more efficiently that reduces the overall carbon footprint. The objective of this paper is to support decisions on selection of appropriate combination of container sizes and shipment consolidation for a manufacturing company. We develop two-steps model which first takes the volumes to be shipped as an input and provide the combination of container sizes required; then ...

The goals of this research are: a) to develop a platform to collect naturalistic video bicycling data, b) to develop a methodology to integrate video data with other sensors that measure cyclists’ position and comfort levels, and c) to apply the platform and data collection methodology to a real-world route. This research effort has successfully integrated video and sensor data to describe cyclists’ comfort levels along a route. It was found ...


Benefit-Cost Analysis For Transportation Planning And Public Policy: Towards Multimodal Demand Modeling, Matthew Holian, Ralph McLaughlin 2016 San Jose State University

Benefit-Cost Analysis For Transportation Planning And Public Policy: Towards Multimodal Demand Modeling, Matthew Holian, Ralph Mclaughlin

Mineta Transportation Institute Publications

This report examines existing methods of benefit-cost analysis (BCA) in two areas, transportation policy and transportation planning, and suggests ways of modifying these methods to account for travel within a multimodal system. Although the planning and policy contexts differ substantially, this report shows how important multimodal impacts can be incorporated into both by using basic econometric techniques and even simpler rule-of-thumb methods. Case studies in transportation planning focus on the California Department of Transportation (Caltrans), but benchmark California’s competencies by exploring methods used by other states and local governments. The report concludes with a list and discussion of recommendations ...

Improving Pathways To Transit For Persons With Disabilities, Stephanie Dipetrillo, Andrea Lubin, Anastasia Loukaitou-Sideris, Carla Salehian, Stephen Gibson, Kristen William, Theodore Trent Green

Mineta Transportation Institute Publications

Persons with disabilities can achieve a greater degree of freedom when they have full access to a variety of transit modes, but this can only be achieved when the pathways to transit – the infrastructure and conditions in the built environment – allow full access to transit stops, stations, and vehicles. Since passage of the Americans with Disabilities Act (ADA) in 1990, many transit agencies and governmental jurisdictions have made significant progress in this area. Policy initiatives, incremental enhancements, modifications, and other measures undertaken by transit agencies and their partners have significantly improved access to transit for persons with disabilities, others who ...

Experimental Modeling Of Nox And Pm Generation From Combustion Of Various Biodiesel Blends For Urban Transport Buses, Ashok Kumar, Dong-Shik Kim, Hamid Omidvarborna, Manideep Yarlagadda, Sudheer Kumar Kuppili, Nader Sawtarie

Mineta Transportation Institute Publications

Biodiesel has diverse sources of feedstock and the amount and composition of its emissions vary significantly depending on combustion conditions. Results of laboratory and field tests reveal that nitrogen oxides (NOx) and particulate matter (PM) emissions from biodiesel are influenced more by combustion conditions than emissions from regular diesel. Therefore, NOx and PM emissions documented through experiments and modeling studies are the primary focus of this investigation. In addition, a comprehensive analysis of the feedstock-related combustion characteristics and pollutants are investigated. Research findings verify that the oxygen contents, the degree of unsaturation, and the size of the fatty acids in ...


Emergency Management Training For Transportation Agencies, Frances Edwards, Daniel Goodrich, James Griffith 2016 San Jose State University

Emergency Management Training For Transportation Agencies, Frances Edwards, Daniel Goodrich, James Griffith

Mineta Transportation Institute Publications

State transportation agencies have a variety of responsibilities related to emergency management. Field personnel manage events--from day-to-day emergencies to disasters--using the Incident Command System (ICS) as their organizational basis. At the headquarters level, the Emergency Operations Center (EOC) coordinates the use of resources across the department and its districts, with other state departments and agencies, and through the federal Emergency Support Function 1. District-level EOCs coordinate with the department. In extreme events, the transportation department may only be able to deliver limited essential services in austere conditions, so a continuity of operations/ continuity of government plan (COOP/COG) is essential ...


Modeling Bus Priority Using Intermodal Dynamic Network Assignment-Simulation Methodology, Khaled F. Abdelghany, Ahmed F. Abdelghany, Hani S. Mahmassani, Akmal S. Abdelfatah 2016 Southern Methodist University

Modeling Bus Priority Using Intermodal Dynamic Network Assignment-Simulation Methodology, Khaled F. Abdelghany, Ahmed F. Abdelghany, Hani S. Mahmassani, Akmal S. Abdelfatah

Ahmed Abdelghany

This article presents a modeling framework that represents bus priority at signalized intersections in the context of its potential network-level and intermodal effects. The model incorporates bus priority within an intermodal dynamic traffic assignment simulation model. It dynamically assigns travelers to different modes and routes in the network according to prevailing traffic conditions, which result from applying a certain network control/bus priority scheme. The model considers changes in traffic conditions as a result of (1) drivers’ route choice adjustments due to changes in traffic signals settings and (2) modal shifts by travelers to take advantage of improved transit service ...

Exploring Bicycle And Public Transit Use By Low-Income Latino Immigrants: A Mixed-Methods Study In The San Francisco Bay Area, Jesus M. Barajas, Daniel G. Chatman, Asha W. Agrawal 2016 University of California - Berkeley

Exploring Bicycle And Public Transit Use By Low-Income Latino Immigrants: A Mixed-Methods Study In The San Francisco Bay Area, Jesus M. Barajas, Daniel G. Chatman, Asha W. Agrawal

Asha W. Agrawal

Latin American immigrants will continue to make up a large share of transit ridership, bicycling and walking in the United States for the foreseeable future, but there is relatively little research about them. This mixed-methods study compares the travel patterns of low-income immigrants living in the San Francisco Bay Area with that of other groups and investigates the barriers and constraints faced by low-income immigrants when taking transit and bicycling. Much of the previous work on immigrant travel has relied on national surveys and qualitative analysis, which underrepresent disadvantaged population groups and slower modes of travel, or are unable to ...


Comparing Data Quality And Cost From Three Modes Of On-Board Transit Passenger Surveys, Asha W. Agrawal, Stephen Granger-Bevan, Gregory Newmark, Hilary Nixon 2016 San Jose State University

Comparing Data Quality And Cost From Three Modes Of On-Board Transit Passenger Surveys, Asha W. Agrawal, Stephen Granger-Bevan, Gregory Newmark, Hilary Nixon

Asha W. Agrawal

This report presents the findings from a research project investigating the relative data quality and administration costs for three different modes of surveying bus passengers that produce results generalizable to the full passenger population. The three modes, all of which used survey methods distributed or administered onboard the transit vehicle, were: self-complete paper surveys, self-complete online surveys, and interviewer-assisted tablet-based surveys. Results from this study indicate several implications for practitioners choosing a survey mode. First, and most importantly, the analysis reinforces the point that there is no single, best survey mode. The choice of mode must depend on an agency ...


Aspirational Planning: A Statistical Model Of Hawthorne Bridge And Tilikum Crossing Bicycle Ride Counts, Robert McCullough, Ramon Cabauatan, Jacob Gellman 2016 McCullough Research

Aspirational Planning: A Statistical Model Of Hawthorne Bridge And Tilikum Crossing Bicycle Ride Counts, Robert Mccullough, Ramon Cabauatan, Jacob Gellman

Hatfield Graduate Journal of Public Affairs

Portland city planners have routinely planned for an increase in bicycle commutership and a decrease in automobile commutership. This paper discusses the latest data on Portland car and bicycle use. Portland and Multnomah County are observing an increase in single occupancy vehicle commuters, car ownership, and gasoline consumption. Bicycle use in Portland is found to have followed a logistic curve pattern since the early 1990s. The authors present an ordinary least squares model to explain bicycle ridership on the Hawthorne Bridge and the recently constructed Tilikum Crossing. When controlling for other factors such as weather and daylight, the Tilikum Crossing ...


The Cycling Gender Gap: What Can We Learn From Girls?, Jennifer Dill 2016 Portland State University

The Cycling Gender Gap: What Can We Learn From Girls?, Jennifer Dill

TREC Friday Seminar Series

In the U.S., women are far less likely to bicycle for transportation than men. Explanations include, among others, safety concerns (traffic and crime), complex travel patterns related to household responsibilities, time constraints, lack of facilities that feel safe, and attitudes. This talk will explore how this gender gap emerges in childhood, using data from the Family Activity Study. The study collected data from 300 Portland families (parents and children) over two years, allowing us to see how things change over time.


On Both Sides Of The Tracks: Light Rail And Gentrification In Portland, Oregon, Nathan Eric Rochester 2016 Portland State University

On Both Sides Of The Tracks: Light Rail And Gentrification In Portland, Oregon, Nathan Eric Rochester

Dissertations and Theses

This study draws on census data and geographic information systems (GIS) to investigate the relationship between light rail transit (LRT) infrastructure development and gentrification in Portland, Oregon. While recent research using comprehensive measures of neighborhood socioeconomic status (SES) supports a potentially causal link between transit development and gentrification, research into the effects of transit on property values alone tends to dominate the discourse. This study therefore seeks to build on previous research to develop an index measure of neighborhood SES and SES change based on measures of education, occupation, and income, using census data from 1980-2010. This multifaceted measure of ...
