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 ...


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 2016 Rutgers University - New Brunswick/Piscataway

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 2016 The University of Toledo

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 ...


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 ...


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 ...

Planning For Bike Share Connectivity To Rail Transit, Greg P. Griffin, Ipek N. Sener 2016 Texas A&M Transportation Institute

Planning For Bike Share Connectivity To Rail Transit, Greg P. Griffin, Ipek N. Sener

Journal of Public Transportation

Bike sharing can play a role in providing access to transit stations and then to final destinations, but early implementation of these systems in North America has been opportunistic rather than strategic. This study evaluates local intermodal plan goals using trip data and associated infrastructure such as transit stops and bike share station locations in Austin, Texas, and Chicago, Illinois. Bike sharing use data from both cities suggest a weak relationship with existing rail stations that could be strengthened through collaborative, intermodal planning. The study suggests a planning framework and example language that could be tailored to help address the ...


Transforming Bus Service Planning Using Integrated Electronic Data Sources At Nyc Transit, Jeffrey Hanft, Shrisan Iyer, Brian Levine, Alla Reddy 2016 New York City Transit

Transforming Bus Service Planning Using Integrated Electronic Data Sources At Nyc Transit, Jeffrey Hanft, Shrisan Iyer, Brian Levine, Alla Reddy

Journal of Public Transportation

The installation of an Automatic Vehicle Location (AVL) system alongside existing Automated Fare Collection (AFC) data spurred development of an inferred bus boarding and alighting ridership model at New York City Transit (NYCT), allowing for 100% passenger origin-destination (O-D) data citywide. Analysis techniques that relied primarily on professional judgment due to lack of data were replaced by more sophisticated statistical techniques. This paper describes two case studies and the resulting service planning potential from having access to fully-integrated big data sources: a neighborhood-wide analysis of performance and ridership, where 100% data allowed planners to pinpoint specific, low-cost reroutes and stop ...


Connecting People To Places: Spatiotemporal Analysis Of Transit Supply Using Travel-Time Cubes, Steven Farber 2016 University of Utah

Connecting People To Places: Spatiotemporal Analysis Of Transit Supply Using Travel-Time Cubes, Steven Farber

TREC Final Reports

Despite its importance, temporal measures of accessibility are rarely used in transit research or practice. This is primarily due to the inherent difficulty and complexity in computing time-based accessibility metrics. Estimating origin-to-destination travel times that include the “last mile” of travel between the transit network and actual start and endpoints of the trip is technically difficult. Not only do such estimations require multimodal network structures, they also require detailed knowledge of transit schedules and sophisticated algorithms for calculating shortest paths using such inputs. Recently, new standards for sharing transit schedules and geographic data, namely the General Transit Feed Specification (GTFS ...
