The Physical Distribution Security System: Who Is Affecting The Vulnerability Of Goods Transprtation?, Luca Urciuoli

Journal of Transportation Management

The purpose of this study is to explore the vulnerability of physical distribution networks to antago- nistic threats. Previous research identifies globalization and Just in Time (JIT) as the main causes of vulnerability. However, cargo crime has always existed, even before the identification of these trends. In this explorative study new factors are brought to light. In particular, it appears that stake- holders’ dynamics are influencing the level of security.

Case Study: University At Albany Develops A Guide To Examine Commuting Behavior And Patterns, Catherine T. Lawson, Mary Ellen Mallia, Chris Franklin, Benjamin Fischer, David Hogenkamp, Matt Ryan

Publications

The University at Albany conducted an examination of campus commuting patterns and behaviors over an eighteen month period. The components included a review of existing options, the development of GIS maps indicating origin points of commutes, a survey of campus perceptions of barriers to using alternative transportation and on-time tracking of mass transit offerings. The study revealed that the success of alternative transportation is hindered by limitations in bus routes and frequency in scheduling, the need for commuters to make additional trips outside their commute route and a distrust of bus reliability.

Carnage Interrupted: An Analysis Of Fifteen Terrorist Plots Against Public Surface Transportation, Research Report 11-20, Brian M. Jenkins, Joseph Trella

Mineta Transportation Institute

This report examines 13 terrorist plots against public surface transportation that were uncovered and foiled by authorities between 1997 and 2010 and two failed attempts to carry out attacks. Certainly, this is not the total universe of foiled or failed terrorist plots in these years, but they were selected on the basis of what is known about them and the accessibility of information. The report focuses on terrorist plots in the West. Seven of the 15 plots took place in the United States, and four occurred in the United Kingdom. These two countries figure prominently as targets of terrorism, and …

An Examination Of Women's Representation And Participation In Bicycle Advisory Committees In California, Research Report Wp 11-03, Hilary Nixon, Cathy Deluca

Mineta Transportation Institute

In the United States, women bicycle at significantly lower rates than men. One method of remedying this disparity is to ensure that women are engaged in bicycle planning and policy making through, for example, participation in bicycle advisory committees (BACs). No research has been conducted on women’s representation and participation in these committees. This study attempts to fill that gap by examining women’s membership levels in and experiences serving on California bicycle advisory committees and bicycle/pedestrian advisory committees. In addition, we explore some of the barriers to participation faced by female cyclists. A survey of 42 committees revealed that women …

A Comparison Of Logistics Strategies And Integration In The U.S. And Ghana, Michael A. Mcginnis, John E. Spillan, Ali Kara, King Obed Domfeh (Dok)

Journal of Transportation Management

This manuscript empirically compares logistics strategies and outcomes in Ghanaian and U.S. firms to test the underlying factor structure and measurement equivalences of the Bowersox/Daugherty model and its relationship with critical success factors. A structured questionnaire was used to gather data from Ghanaian and American logistics managers. Using confirmatory factor analysis (CFA), we compared the three dimensions of Overall Logistics Strategy (OLS) - Process Strategy, Market Strategy, and Information Strategy – in the two countries. A structural equation model (SEM) was then used to assess the impact of OLS on perceived organizational competitiveness in the two countries. Although the economic, …

Assessing The Strategic Evolution Of U.S. Low Cost Airlines In The Post-9/11 Environment, Carl A. Scheraga, Paul Caster

Journal of Transportation Management

It has been suggested in the literature that low-cost airlines have, in varying degrees, departed from the original low-cost model introduced by Southwest Airlines. This study provides a multi-year analysis in the post-9/11 time period, for the years 2004-2009, of the demonstrated strategic positioning choices of U. S. low-cost airlines. The sample utilized is restricted to U. S. low-cost carriers so as not to conflate operating environments. Furthermore, a quantitative methodology is employed to measure effectively these choices and to facilitate inter-airline comparisons. Airlines, as part of their strategic planning process, articulate positions with regard to cost leadership, product differentiation, …

Understanding Supply Chain Security Strategy, Zachary Williams, Jason E. Lueg, Sean P. Goffnett, Stephen A. Lemay, Robert L. Cook

Journal of Transportation Management

In the post-9/11 environment, organizations are acutely aware of the need to secure their supply chains from risks of being a target of, or an unwilling participant in, a terror attack. However, supply chain security (SCS) comes at a cost and increasing levels of protection have increasing levels of costs to the firm. So some firms engage in strategic initiatives to secure the supply chain (SC) while others do not; and each firm engages in varying degrees of activities to ensure SCS. Therefore, in this study, the researchers sought to explore what types of SCS strategies exist. The researchers analyze …

The Role Of Returns Management Orientation, Internal Collaboration, And Information Support In Reverse Logistics, Enping (Shirley) Mai, Haozhe Chen, Kenneth Anselmi

Journal of Transportation Management

While reverse logistics has gained significant interest in recent years, the research on its antecedents is still far from comprehensive. The current study utilizes data collected from China to empirically test a conceptual model that is developed based on the resource based view of the firm. It is proposed that returns management orientation, internal collaboration, and information support are important predictors of reverse logistics performance. The structural equation modeling analysis supports these proposed relationships. Furthermore, the current study also confirms the positive relationship between a firm’s reverse logistics performance and market performance.

Evaluating Network Analysis And Agent Based Modeling For Investigating The Stability Of Commercial Air Carrier Schedules, Sheila Ruth Conway

Engineering Management & Systems Engineering Theses & Dissertations

For a number of years, the United States Federal Government has been formulating the Next Generation Air Transportation System plans for National Airspace System improvement. These improvements attempt to address air transportation holistically, but often address individual improvements in one arena such as ground or in-flight equipment.

In fact, air transportation system designers have had only limited success using traditional Operations Research and parametric modeling approaches in their analyses of innovative operations. They need a systemic methodology for modeling of safety-critical infrastructure that is comprehensive, objective, and sufficiently concrete, yet simple enough to be deployed with reasonable investment. The methodology …

Spatial Analysis Of Travel Behavior And Response To Traveler Information, Xin Wang

Civil & Environmental Engineering Theses & Dissertations

Transportation planners have long recognized that it is urgent to integrate emerging spatial analysis with travel behavior studies. A clearer understanding of the spatial interactions among travelers and the complex environment they face has the potential to reap benefits of the ongoing technologies of travel behavior, spatial analysis and Advanced Traveler Information Systems (ATIS).

Considering that spatial patterns have been overlooked in the literature of travel behavior and ATIS, the main objective of this research is to use robust methods of spatial analysis to enhance the understanding of how the associations between traveler decisions, built environment and socio-demographic characteristics are …

Integrating Probe Vehicles And Stationary Detector Data To Construct Accurate Cumulative Curves To Study Bottlenecks, Khairul Azfi Anuar

Civil & Environmental Engineering Theses & Dissertations

Advancements in sensors technologies have given researchers and practitioners access to an immense amount of traffic data from multiple types of sensors. However, because of the diversity of the data types, developing a relationship between the different data sources can be challenging. To further complicate the issue, the presence of error or noise makes it difficult to infer any reliable conclusions from the data. To develop a relationship between different data sources, a new methodology is proposed in this thesis for fusing stationary detector data and probe vehicle data to construct an accurate cumulative curve. To remove or to reduce …

Analysis Of Primary-Secondary Incident Events On Urban Freeways, Hongbing Zhang

Civil & Environmental Engineering Theses & Dissertations

The objective of this study is to understand the nature of primary and secondary traffic incidents, assess their impacts and explore the implications in traffic operations, safety, and planning. To achieve the objective, a queue-based secondary incident identification method was developed and applied based on detailed incident, traffic and geometric data sets from Hampton Roads, Virginia. This identification method can overcome the limitations in earlier studies and identify secondary incidents in both road directions. An innovative event categorization defines the term "primary-secondary incident event", as one characterized by a primary incident and one or more associated secondary incidents in both …

Shared-Use Bus Priority Lanes On City Streets: Case Studies In Design And Management, Mti Report 11-10, Asha Weinstein Agrawal, Todd Goldman, Nancy Hannaford

Mineta Transportation Institute

This report examines the policies and strategies governing the design and, especially, operations of bus lanes in major congested urban centers. It focuses on bus lanes that operate in mixed traffic conditions; the study does not examine practices concerning bus priority lanes on urban highways or freeways. Four key questions addressed in the paper are: How do the many public agencies within any city region that share authority over different aspects of the bus lanes coordinate their work in designing, operating, and enforcing the lanes? What is the physical design of the lanes? What is the scope of the priority …

The Impact Of Center City Economic And Cultural Vibrancy On Greenhouse Gas Emissions From Transportation, Research Report 11-13, Matthew J. Holian, Matthew E. Kahn

Mineta Transportation Institute

Urban planners and scholars have focused a great deal of attention on understanding the relationship between the built environment and transportation behavior. However, other aspects of the urban environment – including the vibrancy and quality of life in urban areas – have received little attention. This report seeks to close this gap by analyzing the effects of both land-use and urban vibrancy on transportation patterns. Analysis of data from a variety of sources suggests that in addition to the built-environment, the vibrancy of the urban environment also affects transportation behavior. Moreover, vibrancy affects land-use patterns. By integrating objective measures of …
