Kennedy, 60 Minutes, And Roger Rabbit: Understanding Conspiracy-Theory Explanations Of The Decline Of Urban Mass Transit, Martha J. Bianco

Center for Urban Studies Publications and Reports

This paper will review the history of the GM Conspiracy Myth, as well as what legal theorists refer to as "the facts in the case." The legal explanation of what really happened goes only so far, though. The whole story about the decline of mass transit in the U.S. is a story about the failure of public policy and about conflict among competing constituencies in the transportation policy process. This paper will very briefly discuss this failure and this conflict and will then conclude with a consideration of - or at least a hypothesis for - the endurance of the …

The Connection Between Public Transit And Employment, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

Even with a considerable amount of attention being paid to the role of public transportation in addressing inner-city mobility problems, there is very little evidence of the degree to which one affects the other. In other words, little research has specifically focused on how labor participation is impacted by increases in public transportation availability. Research on the spatial mismatch hypothesis has dealt with the relationship between labor participation and the spatial separation of jobs and houses; however, most analyses concentrate on commuting time or distance as a function of auto accessibility. Few, if any, studies have considered the relative impacts …

The Politics Of Implementation: Oregon's Statewide Transportation Planning Rule - What's Been Accomplished, Martha J. Bianco, Sy Adler

Center for Urban Studies Publications and Reports

This paper is a case study of the evolution of Oregon’s groundbreaking Transportation Planning Rule, from its adoption in 1991, up through present amendments. Our analysis is an assessment of how private- and public-sector investors grapple with the coproduction of the built environment under the constraints of a value system that emanates from the state, shepherded by litigious public interest groups. In this case, this value system is articulated in the Oregon administrative rule known as the Transportation Planning Rule. This Rule emphasizes a reduction in the reliance on automobiles and, among other things, requires a decrease in vehicle miles …

Marketing Central City Residence To An Aging Baby Boom: The Transportation Angle, Daphne Spain, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

This paper proposes that the aging baby boom will contribute significantly to transportation problems in the future because 1) current land use patterns necessitate dependence on cars; and 2) aging baby boom women will drive more than elderly women do now. Policies that promote central city residence by stressing the transportation advantages of high-density living, therefore, should have particular appeal to baby boom women seeking prolonged independence. Such policies would also serve the interests of localities by reducing traffic congestion, pollution, and further sprawl. We suggest that a combination of direct and indirect housing policies comparable to those that financed …

The Impact Of Congestion Pricing And Parking Taxes On Spatial Competition, Anthony M. Rufolo, Martha J. Bianco

Center for Urban Studies Publications and Reports

Policymakers seeking to reduce reliance on single-occupant automobiles are giving serious consideration to methods to price roads during periods of congest ion and to increase the cost of parking. Such policies are intended to induce increases in carpooling and in the use of mass transit; however, they may have unintended consequences that counteract these goals in the long run. In particular, actual implementation of such policies may create differential price increases that affect the spatial competition for markets between firms located in the central city and those in the suburbs. Analyzing such policies using the spatial competition models of location …

Mineta International Institute for Surface Transportation Studies, the Silicon Valley Chapter of the Commonwealth Club, the Silicon Valley Manufacturing Group, and the San Francisco Bay Area Metropolitan Transportation Committee, the forum dealt specifically with methods of funding transportation improvements. The traditional way of funding California’s highway system, the gas tax, will soon be unable to keep up with the necessary maintenance and expansion Silicon Valley will require to maintain its status as …

Validation Of Waimss Incident Duration Estimation Model, Wei Wu, Pushkin Kachroo, Kaan Ozbay

Electrical & Computer Engineering Faculty Research

This paper presents an effort to validate the traffic incident duration estimation model of WAIMSS (wide area incident management support system). Duration estimation model of WAIMSS predicts the incident duration based on an estimation tree which was calibrated using incident data collected in Northern Virginia. Due to the limited sample size, a full scale test of the distribution, mean and variance of incident duration was performed only for the root node of the estimation tree, white only mean tests were executed at all other nodes whenever a data subset was available. Further studies were also conducted on the model error …

Wide-Area Incident Management System On The Internet, Kaan Ozbay, Pushkin Kachroo

Electrical & Computer Engineering Faculty Research

The incident management process consists of four sequential steps-incident detection, response, clearance and recovery. Each of these components comprises of a number of operations and coordinated decision-making between the agencies involved. The provision of computer based support tools for the personnel involved will help develop appropriate strategies and increase efficiency and expediency. Existing systems are developed on various traditional computing platforms. However, with the advent of World Wide Web and Internet based programming tools such as Java, it is now possible to develop platform independent decision support tools for the incident management agencies. Any agency will be able to use …

Twenty Years Of Airline Deregulation: The Impact On Outlying Small Communities, J Richard Jones

Journal of Transportation Management

Many rural communities over the years have had to endure reduced levels of scheduled transportation services to the point that some have indeed experienced a cessation of services. Accompanying the deregulation of airlines in 1978 was the expressed fear that transportation services would continue to spiral downward and various communities would lose their population bases. This study investigates the two decades of airline deregulation and the impact that that 1978 legislation has had on small communities that are situated 100 air miles or more from any hub airport. Chief among the findings are: (1) that service levels have indeed deteriorated …

The Oregon Dot Slow-Speed Weigh-In--Motion (Swim) Project: Final Report, James G. Strathman

Center for Urban Studies Publications and Reports

Weigh-in-motion (WIM) systems have provided an effective means of data collection for pavement research and facility design, traffic monitoring, and weight enforcement for over 40 years. In weight enforcement, WIM systems have been increasingly used to screen potentially overweight vehicles. Vehicles that exceed weight limits as measured on a WIM scale are then weighed on a static scale, which is subject to accuracy standards specified by the National Institute of Standards and Technology (1998). The use of WIM for screening purposes reduces queuing at weigh stations, resulting in considerable savings for both truckers and enforcement agencies. To date, however, WIM …

The Commercialization Of Space Transportation: Exploring The Impact Of The National Space Transportation Policy, Thomas L. Johnson

Theses and Dissertations

The 1994 National Space Transportation Policy designates the roles of the DoD, NASA and the Departments of Transportation and Commerce to identify and promote innovative types of arrangements between the U.S. government and the private sector in order to reduce the cost to access space. DoD, civil and commercial industry leaders agree that the price to access space is currently exorbitantly expensive. The solution to this expense, which the United States Government is relying upon, is the commercialization of space transportation technology. This research focuses on investigating the industry and policy commercialization trends which led to the 1994 NSTP, and …

Automatic Replenishment: The Relationship Between Resource Commitment And Program Performance, Alexander E. Ellinger, Patricia J. Daugherty, Chad W. Autry

Journal of Transportation Management

Some firms have adopted a new approach to order fulfillment, i.e., automatic inventory replenishment. With automatic replenishment programs (ARPs), sellers replenish or restock inventory based upon actual product usage and stock level information provided by buyers. This paper reports on a recent survey of logistics professionals regarding .ARP involvement. In addition to providing a profile of current usage, the research also examines the relationship between investment in automatic replenishment related resources and .ARP performance. Firms making a greater commitment to ARP (in terms of resource allocation) reported enhanced day-to-day operational performance and greater success in the overall performance of the …

Assessing The Impact Of The Shortage Of Aviation Maintenance Technicians On Air Transportation, Blaise P. Waguespack Jr., Aleksandar Savic Jr., James S. Baker

Journal of Transportation Management

Global aviation activity is poised for a decade of sustained growth. While economic difficulties are a fact of life in the aviation transportation industry, the future demand for aviation transportation services is promising. One factor that may greatly dampen this projected growth may be the lack of qualified aviation maintenance technicians (AMTs) necessary to keep the air transport fleet flying. This investigation examines the future of global aviation activity while presenting factors impacting the corresponding lack of growth in the AMT population that threaten the future of air transportation.

Mergers And Alliances In The Liner Shipping Industry: An Historical Perspective, David A. Menachof, Anthony Damian

Journal of Transportation Management

This article chronicles the history of mergers and alliances in the liner shipping industry during the past century before focusing on the latest wave of mergers to hit the industry Each merger wave in the liner shipping industry generally coincided with merger waves from the general industrial world. The incentive for each wave of mergers seemed to be different, with the most recent wave focusing on synergy between the merging companies. The reduction of competing firms through mergers has implications for the shipper and these are also examined.

Determinant Criteria In The Ocean Carrier Selection Process, R Stephen Parker, John L. Kent

Journal of Transportation Management

This study examines key determinant criteria used by import and export shippers when selecting an international containership carrier. A sample of import and export shippers were asked to evaluate eighteen service characteristics based on whether or not the characteristics were required by their international containership carriers. The results of Pearson chi-square tests indicate a significant difference between import shippers and export shippers on three of the eighteen service characteristics. Import shippers were more demanding of their carriers by requiring door-to-door transportation rates, shipment expediting, and shipment tracing services.

Increasing Private Sector Participation Of The Airports Authority Of Thailand: A Suggested Model, Upama Jaihong

All-Inclusive List of Electronic Theses and Dissertations

The dynamics of the airport industry have induced a number of countries to undertake airport privatization as a way to provide higher quality airport services and achieve better financial result for both government and the privatized airports. The Airports Authority of Thailand (AAT), facing the increased pressure on airport infrastructure that can accommodate increased air traffic volume, is considering a privatization program to achieve its goals and objectives of enhancing revenues and efficiency. In a study of airport privatization models, research was conducted by analyzing the objectives of privatization, the characteristics and existing environments of major privatized airports in Britain, …

Automated Bus Dispatching, Operations, Control, And Service Reliability: Baseline Analysis, James G. Strathman, Kenneth Dueker, Thomas J. Kimpel, Rick Gerhart, Ken Turner, Pete Taylor, Steve Callas, David Griffin, Janet Hopper

Center for Urban Studies Publications and Reports

The authors of this report are engaged in a long term project to assess the impacts of Tri-Met's BDS on service reliability and transit use. The framework designed for this assessment focuses on documenting service reliability and passenger activity at three major junctures:

• The pre-operational (baseline) period;

• The initial (passive) period following implementation of the new system, when both drivers and dispatchers have access to schedule adherence information in real time, but before the development and use of operations control practices that exploit the information generated by the system;

• Full implementation, when operations control practices are defined …

Household Travel/Activity Decisions: Who Wants To Travel?, Catherine T. Lawson

Center for Urban Studies Publications and Reports

Researchers are using activity-based survey data to better understand the nature of the derived demand for travel. However, a strong theoretical construct for derived demand has yet to be developed. In order to understand the ramifications of considering travel as a derived demand, it is necessary to review some of the basic tenets of economics.

Some activities require travel (i.e. shopping or picking up children from daycare), while others are conducted entirely within the confines of the home. There is a set of activities that can be conducted either in or out of the home. A need to travel arises …

Effects Of Light Rail Transit In Portland: Implications For Transit-Oriented Development Design Concepts, Kenneth Dueker, Martha J. Bianco

Center for Urban Studies Publications and Reports

In the Portland, Oregon, region many local planners have embraced the neotraditional planning concept in the form of transit-oriented development (TOD). One of the primary components of transit-oriented development, light rail transit (LRT), has been in place in Portland long enough to provide data for analysis. Because neotraditional planners often emphasize LRT as a crucial element in decreasing auto use and in encouraging high-density development, this paper examines the effects of LRT in the Portland region including mode share, density, and property values. The empirical analysis provides evidence that light rail alone has not been sufficient to have an appreciable …
