Dealing With The Need Of Greek Ports Expansion : A Public-Private Partnership Opportunity?, Dimitrios Dalaklis, Petros Siousiouras, Antonios Maniatis

Conference Papers

Greece, located at the eastern portion of the Mediterranean Sea (Med) and a country with an enormous number of islands, is a shipping superpower. The Med is amongst the world’s busiest waterways. It provides access to the Black Sea and quite often it is characterized as the most important element of the transport chain between Asia and Europe. The Greek Prime-Minister himself has openly declared his strategic vision to transform the country into a major hub for Europe's commerce; numbers of port-visits in the country under discussion are extremely high and expectations are that with the upcoming recovery of the …

The Long-Term Impact Of Rail Abandonment On Manufacturing In Arkansas, John D. Ozment, Ahren Johnston

Journal of Transportation Management

Despite the fact that railroads are an important part of the U.S. economy, the number of rail carriers and miles of rail lines have been declining. The resulting lack of transportation alternatives could have a negative impact on local manufacturing. This study examined the effects of rail abandonment in Arkansas between 1980 and 2000 by comparing measures related to manufacturing in counties that did not have or had lost some rail service with those in counties that had rail service and had not lost any. The analysis revealed no meaningful differences, suggesting the lack of any adverse economic impacts due …

Key Advertising Components And Media Channels For Recruiting Long Haul Drivers, Marla B. Royne, Carol C. Beinstock, Tracy Anna Cosenza

Journal of Transportation Management

This research examines how trucking companies can develop effective advertising media and messages for reaching and recruiting qualified long distance long distance truck drivers. Long distance truck driver candidates seem most interested in competitive pay, paid vacation, a weekly payment schedule (along with direct deposit), assigned equipment, 24/7 dispatch, a large volume of hub group freight, and flexible home time. To reach this audience and its needs, we suggest advertisements emphasizing these benefits be placed on the Internet and social media sites, as well as in selected professional magazines frequented by truck drivers searching for jobs.

The Role Of Logistics Alliance Orientation On Forming The Alliance Structure: A Conceptual Framework, David M. Gligor, Mary C. Holcomb

Journal of Transportation Management

Little is known about how a firm decides what type of relationship to develop with a LSP and how the type of arrangement affects the service quality performance. This article proposes a conceptual framework to better understand how shippers decide what type of relationship to develop with a logistics service provider (LSP) within the strategy- structure-performance theoretical framework. A systematic literature review is used to develop a conceptual framework that considers the association between the firm’s strategic perspective on outsourcing and the resulting effect on the alliance structure. The concept of a logistics alliance orientation (LAO) is introduced to examine …

Outsourcing Expert Services By State Transportation Departments: A Look At Effects On Cost, Quality, And Changing Employment Levels, Juita-Elena Yusuf, Lenahan O'Connell

School of Public Service Faculty Publications

Privatization has increasingly become a policy option for government agencies struggling to meet rising demands for services but with fewer resources. In the transportation arena, many state departments of transportation (DOTs) have privatized by outsourcing highway functions to the private sector. But the outsourcing of technical and expert services such as those related to the design and construction of highway infrastructure may result in a smaller or less knowledgeable DOT workforce that is unable to perform the necessary contract management to ensure the quality of the work done by contractors. We posit an outsourcing process in which DOTs respond to …

Model Of Urban Freight Transportation: The Case Of Waste Collection, Radim Vecera

Open Access Theses & Dissertations

This thesis introduces the role of urban freight transportation in global economies and its negative environmental impacts. Because the volume of urban freight is continually increasing sustainable measurements have to be implemented during all phases of transportation planning and operation processes.

The thesis is mainly focused on waste collection, as it is an often neglected part of urban freight transportation. Since urban areas are growing the waste collection is starting to be complex problem which is difficult to manage. Therefore different types of optimization software are used to improve the whole process. In this thesis TransCAD software is used to …

Human System Engineering Applications From Distracted Driving Simulations, Holly A.H. Handley, Cansu Kandemir, S. Long (Ed.), E.-H. Ng (Ed.), C. Downing (Ed.)

Engineering Management & Systems Engineering Faculty Publications

Most of the studies to explore the impact of distracted driving have been descriptive in nature; i.e. the research is conducted in naturalistic settings to evaluate the performance of the driver with and without distracters. However simulation models can also be used that predict the workload for driving tasks. Using concepts from process modeling, baseline models of driving tasks can be created for different driving sequences that include the associated fine motor, visual and cognitive human resources. These models can then be used to evaluate incidents of workload overload caused by different distracters, from both the internal and external vehicle …

For Whom The Tunnel Be Tolled: A Four-Factor Model For Explaining Willingness-To-Pay Tolls, Juita-Elena (Wie) Yusuf, Lenahan O'Connell, Khairul A. Anuar

School of Public Service Faculty Publications

This research examines citizen acceptance of tolls and road pricing, and specifically focuses on determinants of the individual’s expressed willingness-to-pay tolls to use a tunnel express lane that would be free of traffic delays. We answer the research question “What factors influence citizens’ willingness-to-pay tolls” by empirically estimating a four factor model of willingness-to-pay: (a) direct benefit to the respondent; (b) relative cost over time; (c) community concern; and (d) political and environmental liberalism. We use data about citizen perceptions from the Life in Hampton Roads Survey, a survey of residents of Hampton Roads, Virginia. We find that willingness-to-pay is …

Modelling Follow Up Time At A Single-Lane Roundabout, Xiaobo Qu, Jin Zhang, Shuaian Wang, Zhiyuan Liu

School of Public Service Faculty Publications

The follow up time is an important parameter for estimating the entry capacity of roundabouts. However, its variability and contributing factors have long been ignored in the literatures. In this study, 171 follow up samples and contributing factors (traffic volume, vehicle position, waiting vehicles behind, vehicle type, and drivers’ gender) are collected at a roundabout in Pacific Pines, Australia. It is found that the follow up time is indeed significantly affected by traffic volume, waiting vehicles behind, vehicle type, and drivers’ gender. In order to establish the relationship between the follow up time and its contributing factors, an inverse Gaussian …

The Modern Streetcar In The United States: Do Cities Have The Information Needed To Make Informed Choices?, Elle Hull

MPA/MPP/MPFM Capstone Projects

Streetcars have made a comeback in cities in North American in the last several decades; there are now over 45 cities operating, building, or planning streetcars. The majority of these streetcars are viewed primarily as catalysts for economic development, rather than as a means of public transportation. However, the streetcar’s claim of promoting development is backed by surprisingly little evidence.

Although carrying out an analysis of the impact of streetcars on economic development is beyond the scope of this paper due to problems with data availability, methods of performing such an analysis are discussed. This includes a list of cities …

Generic Incident Model For Investigating Traffic Incident Impacts On Evacuation Times In Large-Scale Emergencies, Andrew J. Collins, Peter Foytik, Erika Frydenlund, R. Michael Robinson, Craig A. Jordan

VMASC Publications

Traffic incidents cause a ripple effect of reduced travel speeds, lane changes, and the pursuit of alternative routes that results in gridlock on the immediately affected and surrounding roadways. The disruptions caused by the secondary effects significantly degrade travel time reliability, which is of great concern to the emergency planners who manage evacuations. Outcomes forecast by a generic incident model embedded in a microscopic evacuation simulation, the Real-Time Evacuation Planning Model (RtePM), were examined to quantify the change in time required for an emergency evacuation that results from traffic incidents. The incident model considered vehicle miles traveled on each individual …

International Trade With Increasing Returns In The Transportation Sector, Haiwen Zhou

Economics Faculty Publications

In this general equilibrium framework, the transportation sector is modeled as a distinct sector with increasing returns. A more advanced technology has a higher fixed cost but a lower marginal cost of production. Even with both manufacturing firms and transportation firms engaged in oligopolistic competition and optimally choosing their technologies, the model is tractable and results are derived analytically. Technology adoptions in the manufacturing sector and transportation sector are reinforcing, and multiple equilibria may exist. Firms choose more advanced technologies and the prices decrease when the size of the population is larger.

An Explanatory And Comparative Analysis Of Freight Transportation In Eu And U.S. Highways, Luis Alberto Hernandez

Open Access Theses & Dissertations

This thesis provides resources for data collection regarding road freight transportation in the Unites States and the European Union, as well as an explanatory description of data available at each source. Afterwards, individual analysis of the current state of affairs of the highway freight transportation systems in U.S. and EU are performed. Thereafter, an explanatory and comparative analysis between the two land freight transportation systems is performed in terms of regulatory authorities and associations, trucks volume flow, freight weight and volume flow, major issues affecting the system, infrastructure funding sources, and major logistics hubs. Besides, a correlation analysis was performed …

Impacts Of Transportation Infrastructure Proximity And Accessibility On Real Property Values, Arturo Bujanda

Open Access Theses & Dissertations

Investments in public infrastructure such as highways, airports, mass transit, and stadiums can increase adjacent property values, generating a value premium for private developers and adjacent property owners. A portion of this value can be "captured" as public revenue via property taxes to assist financing such improvements. States and local governments aim to anticipate and capture the economic value created by transportation accessibility. While value capture (VC) represents an opportunity for regional agencies to recapture some transportation infrastructure costs, it is not clear how much value is added by the infrastructure in a particular region. This research applies geographic weighted …

Wider Dissemination Of Household Travel Survey Data Using Geographical Perturbation Methods, Kelly J. Clifton, Steven R. Gehrke

Civil and Environmental Engineering Faculty Publications and Presentations

Public agencies spend vast amounts of money collecting information about passenger travel in household travel surveys. These data are valuable for the rich and detailed information they provide, which contribute to regional and statewide travel demand models. These data have utility beyond travel demand modeling in their application to transportation policy and travel behavior research. As the demand on these data increase, so have the quantity of information collected. Detailed geospatial referencing of the home, work and other travel destinations are common practice and permit the integration with other spatially archived data sources, such as land use characteristics, transportation system …

Transportation Needs Of Latinos In Pittsfield, Ma, Daniela Bravo, Aida Palencia, Chanel Fields, Luis Natal, Francisco Rodriguez, Patricia Guardado, Edna Dacosta, Zaida Ismatul, Melissa Correa, July Suarez, Joseli Alonzo, Andrea Ornelas, Phillip Granberry, María Idalí Torres

Gastón Institute Publications

Latinos in Pittsfield are a small but fast growing population. The most significant issue they face is related to transportation. Because the area's lack of population density, Berkshire County Regional Transportation Authority provides limited bus routes. In Massachusetts in 2012, 72% of the population drove to work, while in Berkshire County 86% did. Likewise, in Massachusetts, 9% used public transit but in Berkshire County only 2% did. Massachusetts has failed to enact a Safe Driving Bill, even though Sen. Patricia Jehlen and Rep. Tricia Farley-Bouvier have sponsored H.3285.

Towards Proactive And Flexible Agent-Based Generation Of Policy Packages For Active Transportation, Araz Taeihagh, Rene Bañares-Alcántara

Research Collection School of Social Sciences

One of the approaches gaining ground in policy design is the implementation of combinations of policy measures as policy packages with the aim of increasing efficiency and effectiveness of the designed policies. In this paper, we describe the recent advancements in the developments of a virtual environment for the exploration and analysis of policy packages. The virtual environment uses an agent-based modelling approach for the generation of different configurations of policy measures in the policy packages. The benefit of using the approach is the proactive and flexible generation of policy packages as the agents can react to the changes that …

Investigation Motorcycle Safety At Exit Ramp Sections By Analyzing Historical Crash Data And Rider’S Perception, Hongyun Chen, Chanyoung Lee Ph.D., Aicp, Ptp, Pei-Sung Lin

CUTR Faculty Journal Publications

The purpose of this study is to evaluate the safety performance of four exit ramp types and the major contributing factors on motorcycle crashes and injury severity of motorcycle riders. A six-year crash data were collected in Florida, and a web-based survey (234 samples) was conducted. 573 crashes were found at 419 exits, including 178 diamond exits, 71 directional exits, 85 loop exits and 85 outer connection exits. For a diamond exit, both the survey and crash data showed that this type was safer and more preferable by motorcycle riders; while a loop exit was the most dangerous exit due …

How Livable Is Your Transit System?, Marc Schlossberg

TREC Project Briefs

The U.S. Department of Housing and Urban Development has identified some “livability principles” which include healthy, safe and walkable neighborhoods and safe, reliable and economical transportation choices. Transit agencies and local governments routinely use metrics to evaluate the performance of transit systems, but a uniform standard of transit data collection does not exist outside of the reporting requirements of the National Transit Database (NTD). Because of the types of data collected for the NTD, the focus of performance measurements is often on ridership and financial performance, leaving aside the question of livability.

In an OTREC-sponsored project, principal investigator Marc Schlossberg …
