The study reported on here involved the performance of a broad based assessment of the community level benefits of passenger rail serv ice. The main objective of the research project was to estimate the full range of these benefits at the community level, as opposed to at the state level. Benefits were estimated for individual travelers, Amtrak expenditures, and local businesses. This research indicates local communities currently realize $62.0 million annually in benefits. Additional …
Identifying Traffic Count Posts For Origin-Destination Matrix Adjustments: An Approach To Actual Size Networks, Saeed Asadi Bagolee, Mohsen Asadi, Lorna Richardson
Identifying Traffic Count Posts For Origin-Destination Matrix Adjustments: An Approach To Actual Size Networks, Saeed Asadi Bagolee, Mohsen Asadi, Lorna Richardson
Journal of Transportation Management
For transportation planners, the use of Origin-Destination (OD) matrix adjustment, is receiving considerable attention. However, there are concerns about the validity of results, primarily related to the number and location of traffic count posts. This leads to the question “What would be the best set of traffic count posts to use in OD matrix adjustment modules?” It has been proved that solving this problem is cumbersome. There have been several attempts (either exact or heuristic approaches) to address this problem. But due to the inherent complexities, there is no efficient and easy-to-use methodology able to address situations on the scale …
The Selection Of Transshipment Ports Using A Hybrid Data Envelopment Analysis/Analytic Hierarchy Process, Byung-In Park, Hokey Min
The Selection Of Transshipment Ports Using A Hybrid Data Envelopment Analysis/Analytic Hierarchy Process, Byung-In Park, Hokey Min
Journal of Transportation Management
The accelerated globalization of logistics activities over the last several decades has spurred a rapid expansion of port facilities all cross the world. However, the recent slowdown of international trade, coupled with a global financial crisis, has created an on-going glut of international port facilities throughout the world. Although the abundance of port facilities provides more transshipment options for carriers and shippers, it makes the port selection decision more complex and difficult. To cope with this new set of challenges, this paper proposes a hybrid data envelopment analysis (DEA)/ analytic hierarchy process (AHP) model that is designed to identify factors …

A Study Of Logistics Strategies In Small Versus Large U.S. Manufacturing Firms, John E. Spillan, Jonathan W. Kohn, Michael A. Mcginnis
Journal of Transportation Management
The research reported in this manuscript empirically compares the similarities and differences of logistics strategies for small and large manufacturing firms. The hypotheses focus on whether there are significant differences between logistics strategies of small and large manufacturing firms and whether logistics strategy outcomes differ. The findings indicate that there are many similarities but differences do exist. The results identify dimensions of logistics strategy and assess their impact on logistics coordination effectiveness, customer service commitment, and company/division competitive responsiveness.
Forward Positioning And Consolidation Of Strategic Inventories, Joseph B. Skipper, John E. Bell, William A. Cunningham Iii, Daniel D. Mattioda
Forward Positioning And Consolidation Of Strategic Inventories, Joseph B. Skipper, John E. Bell, William A. Cunningham Iii, Daniel D. Mattioda
Journal of Transportation Management
The forward positioning of strategic inventory in the supply chain has an impact on transportation times and is important for sensitive demand profiles. Consolidation of stocks creates pooling effects and minimizes costs. This study analyzes a current military case where forward consolidation of equipment is considered using optimization, and payback periods are calculated for the cost of consolidating inventory at one of six locations. Results indicate that forward positioning and consolidation reduces time and cost, and also creates savings in reverse logistics flows. The study has implications for geographically diverse supply chains such as humanitarian aid and emergency response operations.
Fuel Costs And Supply Chain Decisions, Cliff Welborn
Fuel Costs And Supply Chain Decisions, Cliff Welborn
Journal of Transportation Management
The affect of rising fuel costs on the individual consumer is well documented in current media. Consumers are paying more for their basic necessities. Fuel surcharge, transportation cost, and logistics have become house hold words. The rising cost of crude oil creates an increase in fuel cost, and this creates an increase in the cost to transport products from one location to another. Managers, who are responsible for acquiring products and delivering them to customers, are also feeling the impact of higher fuel prices. This article will outline three significant areas where fuel prices are affecting U.S. supply chain decisions. …
Adapting Baumol’S Inventory Theoretic To Landed Cost Decisions, Stephan P. Brady, Peter F. Swan, Richard R. Young
Adapting Baumol’S Inventory Theoretic To Landed Cost Decisions, Stephan P. Brady, Peter F. Swan, Richard R. Young
Journal of Transportation Management
Major U.S. corporations have been importers for over 200 years. A significant impetus for “offshoring” has been reducing costs—usually labor costs. Often, other costs were overlooked. There has been a growing disenchantment with sourcing goods overseas, especially when there may be domestic alternatives as other costs begin to dominate. Baumol and Vinod’s Inventory Theoretic model was useful in adding transportation considerations. However, Baumol leaves out several important costs that unless considered in offshoring decisions can lead to suboptimal solutions. This paper extends that model, providing a prescriptive model that could be operationalized by firms to evaluate offshore sourcing decisions.
Avoiding Shipper/Consignee Double Payment Liability, Roger F. Huff
Avoiding Shipper/Consignee Double Payment Liability, Roger F. Huff
Journal of Transportation Management
The purpose of this article is neither to engage in an overly technical legal analysis nor to disparage motor carriers who bring “double liability” claims against financially viable shippers/consignees; after all the trucking company has performed a valuable service and is simply trying to be paid “once” for that service - even though the financially viable shipper or consignee may have to pay twice with the bankrupt/insolvent third party absconding. The purpose of this article is generally to provide some “front-end” practical suggestions to shippers/ consignees in how to avoid being in court on one of these claims in the …
A Longitudial Study Of Private Warehouse Investment Strategies, Jonathan W. Kohn, Michael A. Mcginnis, John E. Spillan
A Longitudial Study Of Private Warehouse Investment Strategies, Jonathan W. Kohn, Michael A. Mcginnis, John E. Spillan
Journal of Transportation Management
This article revisits private warehouse investment decision making, a topic previously examined in 1989 by McGinnis, Kohn, and Myers (1990). Since then there has been a substantial amount of discussion regarding the scope and nature of logistics /supply chain management. In particular the roles of private, contract, and public warehousing has been discussed, increased emphasis on financial performance and strategic decision making may have altered the criteria for investment decisions in private warehousing, increased coordination of supply chains may have altered the relative importance of private, contract, and private warehousing, and increasing emphasis on controlling inventory investment may have shifted …
A Triadic View Of Truck Driver Satisfaction, Stephen A. Lemay, Zachary Williams, Michael Carver
A Triadic View Of Truck Driver Satisfaction, Stephen A. Lemay, Zachary Williams, Michael Carver
Journal of Transportation Management
In this research, the authors surveyed three groups concerning job satisfaction: experienced drivers, new drivers, and managers. Statistical tests were conducted using a sample of 196 new drivers, 145 experienced drivers, and 59 managers from a large TL firm based in the U.S. The results suggest that many discrepancies exist on driver satisfaction among the three perspectives. In particular, new drivers provide managers with opportunities and challenges for satisfaction. Given the current state of the trucking industry, managers will likely benefit from approaching this segment of drivers differently to meet their expectations and keep them from leaving their firms.

The research reported in this manuscript empirically compares the private warehouse investment strategies of small and large manufacturing firms. Mail surveys were administered to independent samples of small and large United States manufacturing firms. This research is based on a series of identically worded questions administered to both samples. Data was factor analyzed and cluster analyzed to identify three private warehouse investment strategies for small and large firms and two strategies for large firms. Analyses of three independent variables further evaluated differences in private warehouse investment strategies. Finally, the warehouse mix of small and of large firms was compared. This …
The Impact Of Hours-Of-Service Regulations On Transportation Productivity And Safety: A Summary Of Findings From The Literature, Hokey Min
Journal of Transportation Management
Since driver fatigue has known to be the primary cause of serious truck crashes, the Federal Motor Carrier Safety Administration (FMCSA) has attempted to implement new hours-of-service (HOS) regulations that aimed to promote safer driving environments. The new HOS regulations effective on October T‘ of2005, however, may lead to substantial cost increases for the trucking industry which will in turn hurt shippers and ultimately customers. For instance, motor carriers may need to hire additional drivers to comply with new HOS regulations requiring that drivers be placed out of service until they accumulated enough off-duty time. In particular, off-duty breaks required …
Roles And Capabilities Of The Retail Supply Chain Organization, C. Clifford Defee, Wesley S. Randall, Brian J. Gibson
Roles And Capabilities Of The Retail Supply Chain Organization, C. Clifford Defee, Wesley S. Randall, Brian J. Gibson
Journal of Transportation Management
Supply chain management (SCM) has become a critical strategic function in recent years. Research in the discipline has been focused toward the upstream side of the supply chain on functions such as warehousing, transportation, procurement and production. As power has shifted downstream toward retailers and their customers, SCM research has been slow to respond. This represents a significant gap, and a significant opportunity. Retailers face challenges that differ from those found in upstream suppliers and manufacturers. We present findings from a study of senior supply chain executives in the retail industry that focuses on the supply chain challenges of greatest …

Results provided include a demographic respondent profile, their organization /functional area preferences and their perspectives on selected entry-level employment issues. These research results are intended to provide employers, educators and students with information that can be used to improve job placement success.
Safety Attitudes And Behavioral Intentions Of Municipal Waste Disposal Drivers, Swartz M. Stephen, Matthew A. Douglas
Safety Attitudes And Behavioral Intentions Of Municipal Waste Disposal Drivers, Swartz M. Stephen, Matthew A. Douglas
Journal of Transportation Management
The Theory of Planned Behavior was used to study factors useful for predicting Behavioral Intentions to commit unsafe acts while driving for commercial drivers working for municipal waste management operations centers. The Theory of Planned Behavior was found to be moderately effective in predicting behavioral intentions, particularly through the constructs of Attitude and Perceived Control. Driver perceptions of safety climate, self-assessed personal safety performance, risk aversion, and attitudes toward behavioral factors associated with engaging in risky behaviors while operating motor vehicles were studied. Risk aversion and driver perception of their own safety performance were also useful predictors of intention.
Moving Towards A Resilient Supply Chain, John Mascaritolo, Mary C. Holcomb
Moving Towards A Resilient Supply Chain, John Mascaritolo, Mary C. Holcomb
Journal of Transportation Management
The nature of supply chain management—global in scope, the existence of interdependent activities in the various processes, the need for collaborative relationships between members, and the uncertainty that is inherent in both supply and demand - makes it vulnerable to unexpected events that have the potential to disrupt operations as planned. Disruptions to the supply chain can have a profound effect on the firm ranging from loss of revenue to increased costs when operations don’t proceed as planned. Firms realized that it was critical to their business interests to proactively manage, and even mitigate, the risks that are inherent in …
Profit Contribution Information’S Impact On Internal Integration, Scott J. Grawe, Haozhe Chen, Daniel D. Mattioda, Patricia J. Daugherty
Profit Contribution Information’S Impact On Internal Integration, Scott J. Grawe, Haozhe Chen, Daniel D. Mattioda, Patricia J. Daugherty
Journal of Transportation Management
An exploratory quantitative study on the relationship between profit contribution information and firm-wide internal integration is presented. Specifically, the authors examine how profit contribution information availability impacts firm-wide internal integration and, subsequently, logistics performance. This study provides greater insight into the area; only a few studies have empirically examined the impact of profit contribution information within a firm. The primary implication is that firms should utilize specific types of information, i.e. profit contribution information, for making more informed operational and strategic decisions. The paper also underscores the managerial value of using profit contribution information in decision making and planning.
The Effects Of Interdepartmental Customer Orientation On Distribution Center Performance, Nancy M. Scott, M Douglas Voss, Scott B. Keller, Matt Schlosser
The Effects Of Interdepartmental Customer Orientation On Distribution Center Performance, Nancy M. Scott, M Douglas Voss, Scott B. Keller, Matt Schlosser
Journal of Transportation Management
Firms have begun to look internally for ways to increase external service quality. ANOVA is used to examine the effect of interdepartmental customer orientation on time, inventory, and customer service-based performance variables in distribution centers. Findings indicate that high interdepartmental customer orientation positively affects distribution center performance in terms of time-based performance measures and customer satisfaction. Interdepartmental customer orientation was found to have only a marginal affect on inventory performance. Implications of the current research for distribution centers and transportation managers are discussed along with limitations and opportunities for future research.

Journal of Transportation Management
Since the terrorist events in the United States on September 11, 2001, the Federal Motor Carrier Safety Administration has been testing and evaluating cargo tracking technologies to improve the safety, security, and efficiency of commercial motor vehicle operations. While satellite-based systems used for tracking vehicles and cargo provide sufficient geographic coverage in the majority of the United States, there remain several vital regions that are uncovered and difficult to monitor. One such region is Alaska, where officials arc particularly concerned with the hazardous materials shipments that are transported parallel to the Trans-Alaska Pipeline. This article analyzes the risks and benefits …
Entry-Level Heavy Truck Drivers And Highway Safety: Is It Finally Time For Federally Mandated Training?, Harry L. Sink
Entry-Level Heavy Truck Drivers And Highway Safety: Is It Finally Time For Federally Mandated Training?, Harry L. Sink
Journal of Transportation Management
This article examines the need for mandated instruction and a uniform curriculum for entry-level commercial drivers. The study also addresses the discontinuity resulting from the establishment of a uniform licensing standard without requiring preparatory training. The research involves a review of Federal regulations pertaining to obligatory operator instruction in the air, water and rail mode. The investigation concludes that weak support and lobbying efforts by certain trucking interests have thwarted the adoption of mandatory instruction and/or a uniform curriculum. The study also highlights a pressing need for policy revision given the imminent retirement of many “baby boom” generation drivers.
A Decision Support Approach To Designing The Inland Logistics Network In China, Hokey Min, Hyun-Jeung Ko, Chin-Soo Lin
A Decision Support Approach To Designing The Inland Logistics Network In China, Hokey Min, Hyun-Jeung Ko, Chin-Soo Lin
Journal of Transportation Management
With the unprecedented growth of international trade, a growing number of multinational firms have coped with logistical challenges of shipping products to and from unfamiliar territories in many countries. These logistical challenges include the cross-border transportation of products originated from inland port to another inland port isolated from major waterways. In particular, the lack of access to major waterways would not only constrain the intermodal transportation option, but also make door-to-door, containerized delivery services nearly impossible. Such a limited option would eventually lead to increased transportation costs and transit time, and thereby offset low-cost global sourcing advantages. To aid multinational …

Transportation Management Systems: An Exploration Of Progress And Future Prospects., Stanley E. Griffis, Thomas J. Goldsby
Transportation Management Systems: An Exploration Of Progress And Future Prospects., Stanley E. Griffis, Thomas J. Goldsby
Journal of Transportation Management
This research reports the experiences of both adopters and non-adopters of transportation management system (TMS) technology. TMS adopters represent a diverse array of companies, with a surprisingly high percentage of adopters using outsourced services for decision support activities. Motives for adoption tend to align with the firm’s strategic needs though functionality focuses on the shipper’s day-to-day operational needs. While expectations of system performance and return on investment vary greatly, TMS users illustrate a generally high level of satisfaction. Non-adopters view decision support for transportation activities as a low priority. The article explores future prospects for TMS development and adoption.
